Hygiene Hypothesis is a hypothesis that states that a lack of early childhood exposure to infectious agents, symbiotic microorganisms (such as the gut flora or probiotics), and parasites increases susceptibility to allergic diseases by suppressing the natural development of the immune system. In particular, the lack of exposure is thought to lead to defects in the establishment of immune tolerance. Personal Hygiene

Cholera is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. Undercooked seafood is a common source. Humans are the only animal affected. Risk factors for the disease include poor sanitation, not enough clean drinking water, and poverty. Cholera can be diagnosed by a stool test.  A rapid dipstick test is available but is not as accurate. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Wiping your Butt.

Hands Back and front Hand is a prehensile, which is the quality of an appendage or organ that has adapted for grasping or holding. A multi-fingered organ located at the end of the forearm or forelimb.
Index Finger is the first finger and the second digit of a human hand. (pointer finger)
Middle Finger is the third digit of the human hand, located between the index finger and the ring finger. It is usually the longest finger.
Ring Finger is the fourth proximal digit of the human hand, and the second most ulnar finger, located between the middle finger and the little finger.
Little Finger or pinky, is the most ulnar and usually smallest finger of the human hand, opposite the thumb, and next to the ring finger.
Thumb is the first digit of the hand. When a person is standing in the medical anatomical position (where the palm is facing to the front), the thumb is the outermost digit.

Feet Foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws or nails. The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments. The joints of the foot are the ankle and subtalar joint and the interphalangeal articulations of the foot.

Podoconiosis also known as nonfilarial elephantiasis, is a disease of the lymph vessels of the lower extremities that is caused by chronic exposure to irritant soils. It is the second most common cause of tropical lymphedema after filariasis, and it is characterized by prominent swelling of the lower extremities, which leads to disfigurement and disability. Prior to the development of lymphatic failure and frank lymphedema, a prodrome consisting of itching, burning, hyperkeratosis, plantar edema, and rigid digits may occur. As with other forms of tropical lymphedema, chronic disease can lead to fusion of the toes, ulceration, and bacterial superinfection. The disease has an acute component, and sufferers may experience recurrent episodes of lower extremity warmth, firmness, and pain. The cornerstone of prevention and treatment of podoconiosis is avoidance of exposure to irritant soils. Wearing shoes in the presence of irritant soils is the primary method of exposure reduction. In Rwanda, a country of high disease prevalence, the government has banned walking barefoot in public, in order to curtail podoconiosis and other soil-borne diseases. Once the disease has developed, rigorous foot hygiene including daily washing with soap and water, application of an emollient, and nightly elevation of the affected extremity has been shown to reduce swelling and disability. Compression wrapping and decongestive physiotherapy of the affected extremity has been shown to be effective in other forms of lymphedema, but the benefits of these therapies have not been rigorously studied in podoconiosis. Nodules will not resolve with these conservative measures, although surgical removal of the nodules can be performed.

Nails


Finger Nail Diagram Nail is a horn-like envelope covering the tips of the fingers and toes in humans. Nails are similar to claws in other animals. Fingernails and toenails are made of a tough protective protein called keratin which is a fibrous structural proteins that protects epithelial cells from damage or stress. It is the key structural material making up the outer layer of human skin.

Nail Biting (bad habits)

Fingernail Care: To keep your fingernails looking their best: Keep fingernails dry and clean. This prevents bacteria from growing under your fingernails. Repeated or prolonged contact with water can contribute to split fingernails. Wear cotton-lined Rubber Gloves when washing dishes, cleaning or using harsh chemicals. Practice good nail hygiene. Use a sharp manicure scissors or Clippers. Trim your nails straight across, then round the tips in a gentle curve using a Nail File. Use moisturizer. When you use hand lotion, rub the lotion into your fingernails and cuticles, too. Apply a protective layer. Applying a nail hardener might help strengthen nails. Ask your doctor about biotin. Some research suggests that the nutritional supplement biotin might help strengthen weak or brittle fingernails.

Manicure consists of filing and shaping the free edge, pushing and clipping (with a cuticle pusher and cuticle nippers) any nonliving tissue (but limited to the cuticle and hangnails), treatments with various liquids, massage of the hand, and the application of fingernail polish. When the same is applied to the toenails and feet, the treatment is referred to as a pedicure, which is treatment of the feet and toenails that include care not only for the toenails; dead skin cells are rubbed off the bottom of the feet using a rough stone (often a pumice stone). Skin care is often provided up to the knee, including granular exfoliation, moisturizing, and massage.



Hair


Hair Types Hair is a protein filament that grows from follicles found in the dermis, or skin. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine Vellus Hair. Most common interest in hair is focused on Hair Growth, hair types and Hair Care, but hair is also an important biomaterial primarily composed of protein, notably Keratin, which is one of a family of fibrous structural proteins. It is the key structural material making up hair, horns, claws, hooves, and the outer layer of human skin. Keratin is also the protein that protects Epithelial cells from damage or stress. Keratin is extremely insoluble in water and organic solvents. Keratin monomers assemble into bundles to form intermediate filaments, which are tough and form strong unmineralized epidermal appendages found in reptiles, birds, amphibians, and mammals. The only other biological matter known to approximate the toughness of keratinized tissue is Chitin, which is a long-chain polymer of N-acetylglucosamine, is a derivative of glucose. It is a primary component of cell walls in fungi, the exoskeletons of arthropods, such as crustaceans (e.g., crabs, lobsters and shrimps) and insects, the radulae of molluscs, cephalopod beaks, and the scales of fish and lissamphibians. The structure of chitin is comparable to another polysaccharide - cellulose, forming crystalline nanofibrils or whiskers. In terms of function, it may be compared to the protein keratin. Chitin has proved useful for several medicinal, industrial and biotechnological purposes.

Hair Follicle resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides and immune cells. This complex interaction induces the hair follicle to produce different types of hair as seen on different parts of the body. For example, terminal hairs grow on the scalp and lanugo hairs are seen covering the bodies of fetuses in utero and in some new born babies. The process of hair growth occurs in distinct sequential stages. The first stage is called anagen and is the active growth phase, catagen is the resting stage, telogen is the regression of the hair follicle phase, exogen is the active shedding of hair phase and lastly kenogen is the phase between the empty hair follicle and the growth of new hair. Hair Pulling

Human Hair Growth occurs everywhere on the body except for the soles of the feet, the lips, palms of the hands, some external genital areas, the navel, scar tissue, and, apart from eyelashes, the eyelids. Like skin, hair is a stratified squamous keratinized epithelium made of multi-layered flat cells whose rope-like filaments provide structure and strength to the hair shaft. Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen phases. Each phase has specific characteristics that determine the length of the hair. All three phases occur simultaneously; one strand of hair may be in the anagen phase, while another is in the telogen phase. The body has different types of hair, including vellus hair and androgenic hair, each with its own type of cellular construction. The different construction gives the hair unique characteristics, serving specific purposes, mainly warmth and protection. Most humans develop the longest thickest hair on their scalps and (mostly observed in males) faces. This hair will usually grow to several feet before terminating, but many humans develop much longer hair.

Ingrown Hair is a condition where hair curls back or grows sideways into the skin. The condition is most prevalent among people who have coarse or curly hair. It may or may not be accompanied by an infection of the hair follicle (folliculitis) or "razor bumps" (pseudofolliculitis barbae), which vary in size. While ingrown hair most commonly appears in areas where the skin is shaved or waxed (beard, legs, pubic region), it can appear anywhere. Anything which causes the hair to be broken off unevenly with a sharp tip can cause ingrown hairs. Ingrown hairs are also caused because of lack of natural exfoliation in the skin.

Hair Care is an overall term for hygiene and cosmetology involving the hair which grows from the human scalp, and to a lesser extent facial, pubic and other body hair. Hair care routines differ according to an individual's culture and the physical characteristics of one's hair. Hair may be colored, trimmed, shaved, plucked, or otherwise removed with treatments such as waxing, sugaring, and threading. Hair care services are offered in salons, barbershops, and day spas, and products are available commercially for home use. Laser hair removal and electrolysis are also available, though these are provided (in the US) by licensed professionals in medical offices or specialty spas.

Hair Cutting - Styling Hair - Hair Washing

Bowl Cut or bowl haircut, is a simple, plain, and short haircut where the hair is cut with a straight fringe on the front and the rest of the hair is the same length all the way around or is cut short on the sides and back. It is so named because it looks as though someone were to place a bowl on the head and cut off or trim all of the hair to a very short length. A bowl cut is also known for being a cheap and easy haircut often sported by children, typically in less developed countries worldwide. Historically, the bowl haircut was popular among common people of various nationalities as an easy and relatively neat cut by a non-professional. Indeed, it was done by putting a cooking pot of a fit size to the level of the ears, and all hair below the rim was cut or shaved off. In some cultures it was a normal type of haircut. In other cultures the bowl cut was viewed as an attribute of poverty, signifying that the wearer could not afford to visit a barber.

Layered Hair is a hairstyle that gives the illusion of length and volume using long hair for the illusion of length and short hair for volume, as an easy style to manage. Hair is arranged into layers, with the top layers (those that grow nearer the crown) cut shorter than the layers beneath. This allows the tips of the top layers to blend apparently seamlessly with layers beneath.

Your hair stores a permanent record of the toxins you ingest. A standard hair drug test searches for traces of drugs consumed over the last 90 days. But take longer strands of hair or some slow-growing body hair and you can easily put the last year of your life under the microscope.

Body Hair, or androgenic hair, is the terminal hair that develops on the human body during and after puberty. It is differentiated from the head hair and less visible vellus hair, which are much finer and lighter in color. The growth of androgenic hair is related to the level of androgens (often referred to as male hormones; due to the production levels in males being higher on average, but it is actually present in both sexes, and therefore is a unisex hormone) in the individual.

Vellus Hair is short, thin, slight-colored, and barely noticeable thin hair that develops on most of a person's body during childhood. Exceptions include the lips, the back of the ear, the palm of the hand, the sole of the foot, some external genital areas, the navel, and scar tissue. The density of hair – the number of hair follicles per area of skin – varies from person to person. Each strand of vellus hair is usually less than 2 mm (1/13 inch) long and the follicle is not connected to a sebaceous gland. Vellus hair is most easily observed on children and adult women, as it generally has less terminal hair to obscure it. Vellus hair is not lanugo hair. Lanugo hair is a much thicker type of hair that normally grows only on fetuses. Vellus hair is differentiated from the more visible terminal or androgenic hair, which develops only during and after puberty, usually to a greater extent on men than it does on women. The Latin language uses the word vellus to designate "a fleece" or "wool". In slang usage, vellus hair is sometimes referred to as "peach fuzz" due to its resemblance to the downy epidermic growths on the peach fruit. Compared to other animals, humans appear relatively hairless, but you have more hair follicles crammed onto each square inch of your skin than the hairiest chimpanzee, monkey, or gorilla. The difference is that most of your hair (whether you’re a man or a woman) is nearly invisible. It consists of a fine, slow-growing, almost colorless covering of downy hair called vellus hair. Vellus hair blankets your body, insulating your skin and heightening your sensitivity to touch. It’s the reason you can sometimes “feel” a person moving past you in a darkened room—the passing air currents disturb your fine hairs and trigger the sensitive nerves attached to them. However, vellus hair is easily overlooked and nearly invisible without a magnifying glass. It’s sometimes known as “peach fuzz.”

Terminal Hair are thick, long, and dark, as compared with vellus hair. During puberty, the increase in androgenic hormone levels causes vellus hair to be replaced with terminal hair in certain parts of the human body. These parts will have different levels of sensitivity to androgens, primarily of the testosterone family. The Pubic area Hair is particularly sensitive to such hormones, as are the armpits which will develop axillary hair. Pubic and axillary hair will develop on both men and women, to the extent that such hair qualifies as a secondary sex characteristic, although males will develop terminal hair in more areas. This includes facial hair, chest hair, abdominal hair, leg and arm hair, and foot hair. Human females on the other hand can be expected to retain more of the vellus hair. Terminal Hair is the more obvious hair found on your body, including the hair on your head, your eyebrows, and your eyelashes. After puberty, terminal hair appears in many more places on your body—some where it’s wanted, and some where it’s decidedly inconvenient. Your eyebrow and eyelash hair also provide a home for a bizarre, sausage-shaped created called Demodex. It doesn’t spread disease or cause irritation, except in people who have severely compromised immune systems due to some other disease. The terminal hair on your eyelashes keeps dirt and insects out of your eyes. Your ear hairs and nose hairs play a similar role. The terminal hair on your eyebrows prevents sweat and rain from dripping onto your face. On your head, terminal hair helps prevent sunburns on sunny days and heat loss on cold ones. Pubic Hair is a type of terminal hair that serves as a secondary sexual characteristic. That means it’s there to advertise that you’re a fully functioning adult with the appropriate baby-making abilities. Hair doesn’t grow faster or thicker after you shave it (on any part of your body). Hair doesn’t grow faster at night. Female hair doesn’t grow faster during menstruation. Instead, all hair grows at a constant rate with a brief resting period. Frequent washing, blow drying, and dyeing your hair activities might make your current hair more brittle and fragile. But even if you damage a hair to the point of falling out, the same hair follicle will produce a new one to take its place. You’re born with all the hair follicles you’ll ever have. As you grow and your skin stretches from infant-sized to adult proportions, your hair follicles simply become more spread out. While you’re pregnant, each hair clings on a little bit longer, eventually giving you a fuller head of hair. After you give birth, your body sheds its hair more quickly to make up for lost time. The only ways to remove hair permanently are laser hair removal and electrolysis. Both treatments take numerous sessions over the course of many months, and neither treatment works for all people or all hair. Wearing hats doesn’t cause hair loss. Male-pattern baldness, which causes the infamous ring-around-the-bald-spot effect, develops gradually and eventually affects about two-thirds of all men. Its causes are genetic, and its treatments are few.

The average scalp has 100-150 thousand hairs. Hair is so strong that if you made all of your hair into a rope, it could hold 10-15 tons or about 3.5 ounces per strand. Hair also has the highest rate of cell division in the body. It grows at .3mm per day on average, and 1 cm per month. Thankfully, each hair has its own life cycle. If it didn’t, instead of losing hair randomly, we would molt. Hair grows in three phases: Anagen- The active growth stage (80-85% of hair is in this phase); Catagen- This phase is also known as the transitional phase, when hair begins to stop growing; and telogen- this phase is when hair growth is completely shut down and the fibers fall out (10-15% of our hair is in this phase at any given time). After your hair goes through the Telogen phase, Anagen begins again and voila! More hair! Melanin is a common amino acid in most all living organisms on planet Earth. Interestingly, spiders are one of only a few species that do not produce melanin.

Nitpicking is the act of removing Nits (the eggs of Lice, generally Head Lice) from the host's hair. As the nits are cemented to individual hairs, they cannot be removed with most lice combs and before modern chemical methods were invented, the only options were to shave all the host's hair or to pick them free one by one. This is a slow and laborious process, as the root of each individual hair must be examined for infestation. It was largely abandoned as modern chemical methods became available; however, as lice populations can and do develop resistance, manual nitpicking is still often necessary.

Shaving is the removal of hair, by using a razor or any other kind of bladed implement, to slice it down—to the level of the skin or otherwise. Shaving is most commonly practiced by men to remove their facial hair and by women to remove their leg and underarm hair. A man is called clean-shaven if he has had his beard entirely removed.

Bathing


How often you should bathe depends on many different factors

Hygiene for Kids Bathing is the washing of the body with a fluid, usually water or an aqueous solution, or the immersion of the body in water.

Personal Grooming is the art of cleaning, grooming, and maintaining parts of the body.

Experts tend to agree that most people should avoid showering too frequently and in fact, if they reduce the frequency it can be an incredibly healthy decision for their skin. The exceptions to this rule are people who commute in the subway or other crowded spaces, go to the gym daily or are in contact with potentially sick people (such as those coughing, sneezing or sniffling during the flu season). In most cases you only need to shower twice out of each three days and some people can do so just every other day. When you avoid showering daily, your skin is better able to maintain its balance, making it radiant and healthy. The important thing is to remember to use a wash cloth on any specific areas that need daily attention for hygienic or smell-related reasons. Washing your hair no more than two times a week should help maintain the natural oil production, while achieving moisture balance. And if you have coarse or curly hair, try once every seven days. If you feel the need to wash your hair every day because you use public places that are filled with bacteria (like the subway or buses), or have a job that is physically demanding, or exercise regularly, don't worry. Try to use sulfate-free shampoos and protein conditioning treatment

Shower Cap is a cover worn on top of the head while showering or bathing to protect hair from becoming wet.

Bathing Tips
Don't forget to clean your feet. Shampoo your hair no more than two times a week. Apply hair conditioner on your roots first. A long shower can actually remove much-needed moisture from the skin, especially a hot shower. This can leave your skin feeling dry and itchy. A shower should be 5 to 10 minutes long. A burst of cold water at the end of your shower can be quite good for you. helps increased tolerance to stress, can boost your immune system, increased fat burning, and has anti-depressant effects. Use a fluffy towel to lightly pat, not scrub or rub, your body. Moisturize your skin while it is still damp.

Mindfulness Showering
When taking a shower you should use that moment to notice your senses, feel the temperature of the water, intimately experiencing the soap against your skin and the sensual experience of a showering. Smell the aromas of the soap, listen to the running water or the feeling of rubbing shampoo into your scalp. Think of your showering as a metaphor for washing away stale irrelevant thoughts, feelings and bad memories. Negative ions produced by running water can also cleanse the aura.

Skin Layers Skin is the soft outer covering of vertebrates. An organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs. Cuts

Skin Color - Pore Sweat Glands - Skin Picking - Touching - Skin Product Warnings

Integumentary System is the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside. The system comprises the skin and its appendages (including hair, scales, feathers, hooves, and nails).

Epidermis is the outer two layers that make up the skin (or cutis), the inner layer being the dermis. It provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss (TEWL). The outermost part of the epidermis is composed of a stratified layer of flattened cells, that overly a basal layer (stratum basale) composed of columnar cells arranged perpendicularly. Stratum Corneum is the outermost layer of the epidermis, consisting of dead cells (corneocytes). This layer is composed of 15–20 layers of flattened cells with no nuclei and cell organelles. Their cytoplasm shows filamentous keratin. These corneocytes are embedded in a lipid matrix composed of ceramides, cholesterol, and fatty acids. Stratum Spinosum is a layer of the epidermis found between the stratum granulosum and Stratum Basale, which is the deepest layer of the five layers of the epidermis, the outer covering of skin in mammals.

Dermis is a layer of skin between the epidermis (with which it makes up the cutis) and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain. It is divided into two layers, the superficial area adjacent to the epidermis called the papillary region and a deep thicker area known as the reticular dermis. The dermis is tightly connected to the epidermis through a basement membrane. Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat. In addition, hair follicles, sweat glands, sebaceous glands, apocrine glands, lymphatic vessels and blood vessels are present in the dermis. Those blood vessels provide nourishment and waste removal for both dermal and epidermal cells. Your Fingerprints were formed while you were still in your mother’s womb. To biologists, fingerprints are known as friction ridges, and they’re thought to improve our sense of touch. They might also give you a better grip on small, wet objects. And thanks to your sebaceous glands and your sweat glands, your fingerprints leave wet, oily tracks wherever they’ve been.

A newfound organ, the interstitium, is seen here beneath the top layer of skin, but is also in tissue layers lining the gut, lungs, blood vessels, and muscles. The organ is a body-wide network of interconnected, fluid-filled compartments supported by a meshwork of strong, flexible proteins.

Sun Burn - Degree of Burns

Acne also known as acne vulgaris, is a long-term skin disease that occurs when hair follicles are clogged with dead skin cells and oil from the skin. It is characterized by blackheads or whiteheads, pimples, oily skin, and possible scarring. It primarily affects areas of the skin with a relatively high number of oil glands, including the face, upper part of the chest, and back. The resulting appearance can lead to anxiety, reduced self-esteem and, in extreme cases, depression or thoughts of suicide. The role of diet and cigarette smoking is unclear, and neither cleanliness nor exposure to sunlight appear to play a part. During puberty, in both sexes, acne is often brought on by an increase in hormones such as testosterone. A frequent factor is excessive growth of the bacterium Propionibacterium acnes, which is normally present on the skin. Many treatment options for acne are available, including lifestyle changes, medications, and medical procedures. Eating fewer simple carbohydrates such as sugar may help. Treatments applied directly to the affected skin, such as azelaic acid, benzoyl peroxide, and salicylic acid, are commonly used. Antibiotics and retinoids are available in formulations that are applied to the skin and taken by mouth for the treatment of acne. However, resistance to antibiotics may develop as a result of antibiotic therapy. Several types of birth control pills help against acne in women. Isotretinoin pills are usually reserved for severe acne due to greater potential side effects. Early and aggressive treatment of acne is advocated by some in the medical community to decrease the overall long-term impact to individuals. In 2015, acne was estimated to affect 633 million people globally, making it the 8th most common disease worldwide. Acne commonly occurs in adolescence and affects an estimated 80–90% of teenagers in the Western world. Lower rates are reported in some rural societies. Children and adults may also be affected before and after puberty. Although acne becomes less common in adulthood, it persists in nearly half of affected people into their twenties and thirties and a smaller group continue to have difficulties into their forties.

Dermatitis also known as eczema, is a group of diseases that results in inflammation of the skin. These diseases are characterized by itchiness, red skin, and a rash. In cases of short duration there may be small blisters while in long-term cases the skin may become thickened. The area of skin involved can vary from small to the entire body. Dermatitis was estimated to affect 245 million people globally in 2015. Some common emollients for the relief of eczema include Oilatum, Balneum, Medi Oil, Diprobase, bath oils and aqueous cream. Sebexol, Epaderm ointment, Exederm, and Eucerin lotion or cream may also be helpful with itching. Lotions or creams may be applied directly to the skin after bathing to lock in moisture. Moisturizing gloves (gloves which keep emollients in contact with skin on the hands) can be worn while sleeping. Generally, twice-daily applications of emollients work best. While creams are easy to apply, they are quickly absorbed into the skin, and therefore need frequent reapplication. Ointments, with less water content, stay on the skin for longer and need fewer applications, but they can be greasy and inconvenient. Recently, ceramides, which are the major lipid constituent of the stratum corneum, have been used in the treatment of eczema. They are often one of the ingredients of modern moisturizers. These lipids were also successfully produced synthetically in the laboratory. A randomized control trial in infants found that subjects with atopic dermatitis that were treated with emollients (e.g., Eucerin, Cetaphil, Nutraderm) had significantly decreased requirements for topical steroids compared with a control group who were not treated with them. Emollients are best applied immediately after bathing when the skin is well hydrated.

Necrosis is a form of cell injury which results in the premature death of cells in living tissue by autolysis, which refers to the destruction of a cell through the action of its own enzymes, which are catalysts that increase the rate of a reaction by lowering its activation energy. Most enzymes are proteins.

Swimmer's Itch is a short-term immune reaction occurring in the skin of humans that have been infected by water-borne schistosomatidae. Symptoms, which include itchy, raised papules, commonly occur within hours of infection and do not generally last more than a week. It is common in freshwater, brackish and marine habitats worldwide. Incidence may be on the rise, although this may also be attributed to better monitoring. There are no permanent effects to people from this condition. Orally administered hydroxyzine, an antihistamine, is sometimes prescribed to treat swimmer's itch and similar dermal allergic reactions. In addition, bathing in oatmeal, baking soda, or Epsom salts can also provide relief of symptoms.

Schistosomatidae is a family of digenetic trematodes with complex parasitic life cycles. Immature developmental stages of schistosomes are found in molluscs and adults occur in vertebrates. The best studied group, the blood flukes of the genus Schistosoma, infect and cause disease in humans. Other genera which are infective to non-human vertebrates can cause mild rashes in humans. Schistosomatids are dioecious (individuals are of separate sexes) which is exceptional with regards to their phylum, Platyhelminthes, in which most species are hermaphrodidic (individuals possess both male and female reproductive systems). Cercarial Dermatitis.

Germ Theory of Disease states that some diseases are caused by microorganisms.

Exfoliation (cosmetology) involves the removal of the oldest dead skin cells on the skin's outermost surface. Exfoliation is involved in the process of all facials, during microdermabrasion or chemical peels. Exfoliation can be achieved through mechanical or chemical means. You should exfoliate two to three times a week for normal and combination skin, and once a week for sensitive skin.

Facial is a family of skin care treatments for the face, including steam, exfoliation, extraction, creams, lotions, facial masks, peels, and massage. They are normally performed in beauty salons, but are also a common spa treatment. They are used for general skin health as well as for specific skin conditions. Types of facials include European facial, LED light therapy facials, and mini-facials.

Why is skin thick on the soles of the feet?

Callus is a toughened area of skin which has become relatively thick and hard in response to repeated friction, pressure, or other irritation.

Blister is a small pocket of lymph within the upper layers of the skin, typically caused by forceful rubbing (friction), burning, freezing, chemical exposure or infection. Most blisters are filled with a clear fluid, either serum or plasma. However, blisters can be filled with blood (known as blood blisters) or with pus (if they become infected).

Tissue (biology) is a cellular organizational level between cells and a complete organ. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.

Tetrakaidecahedrons Skin Layer A few millimeters of tissue keeps their blood from oozing out of their body. It helps keep water and nutrients inside your body, where they belong, and it keeps undesirable elements—like toxins and marauding bacteria—outside most of the time. Skin does far more than the obvious task of keeping your insides on the inside. It’s a washable, stretchable, self-repairing fabric that lasts a lifetime with minimal care. It’s also home to your hair, nails, and sweat glands. If your skin was laid flat, your skin occupies about 20 square feet of space.

When your body produces fresh skin cells, these newcomers push the older cells out of the crowded neighborhood at the base of the epidermis and toward the surface of the skin. The trip takes anywhere from a couple of weeks to a month. By the time a skin cell reaches the surface, it’s little more than a dead, scale-like structure that’s filled with keratin but none of the ordinary cellular machinery. Each surface skin cell lasts about 30 days on the outside, which means you get an entirely new skin every month.

You lose millions of dead skin cells every day, that's 30,000 or so scales of skin that flake off your body every minute. Because skin flakes are thin and nearly transparent, your household dust almost always has a light, silvery-grey color. Dust mites are common, they're very tiny and distant relatives of the common household spider. Dust Mites live in our houses by the millions, with most of them taking up residence in upholstered furniture, drapery, carpets, and—above all—mattresses. Dust mites need just three things for a life of contentment: warmth, moisture, and a steady diet of skin flakes. In your bed, they get all three. Dust mites have absolutely no interest in crawling on your body. But dust-mites may cause allergies that include sore eyes, an itchy throat, and sneezing fits. You can wash your bedding at high temperatures—at least 130 degrees Fahrenheit, or use zippered covers for mattresses and pillows that can reduce the number of dust mites. Dust mites actually eat and excrete the same skin flake several times, until they’ve finally digested all the goodness out of it.

capillary loop regulates skin temperature Body Temperature Regulator. Using a design that’s the human equivalent of a hot-water radiator, your body sends warm blood to the surface of your skin so it can radiate heat away to the cooler world outside. When you need to conserve heat, your body clamps down on this process, tightening the blood vessels in your skin. That reduces the flow of blood near the skin and slows your rate of heat loss. This system explains why people become flushed when they’re hot (it’s from the increased blood flow). It also explains how frostbite inflicts its damage. The cold itself doesn’t harm your body—instead, the extremely reduced blood flow starves your cells of the oxygen they need to survive.

Vitamin D: Sun exposure that you need to synthesize vitamin D is very little in the summer months (or in a tropical climate). But in late fall and winter, you can run around in boxer shorts without producing a microgram of vitamin D. But try not to linger in the sun between 10 a.m. and 3 p.m. (11 a.m. and 4 p.m. during daylight-saving time). If you find yourself in strong sun, seek shade. Always wear a wide-brimmed hat, long-sleeved shirt, and long pants on sunny days. Use sunscreen that protects against both UVA and UVB Rays and offers a sun protection factor (SPF) of at least 15. Use sunscreen properly. Apply sunscreen 15 to 30 minutes before going out. Repeat every two or three hours, more often if you’re swimming.

Don't Shower too Much


1. Make the Skin Softer
Your skin receives its hydration from two main sources. It attracts moisture that is in the air and it also gets hydration from the beneficial oils and water found within your body. It is important to keep in mind that when the air outside gets dryer, your skin will as well as there is less moisture for it to attract. Some people decide to use a lot of moisturizer to solve the problem but a better option can be showering less often. That is because when you use hot water (which most people do, especially in cooler months), it will soften your skin’s oils, making it easier for them to wash away and therefore dry out your skin. This means that ideally you should shower less frequently and opt for a nontoxic soap in the locations you need it. If you do this, your skin should be able to find a happy healthy balance by itself. If you feel you need more, opt for pure shea butter creams or organic raw oils such as olive, jojoba and coconut. Hot water is bad for two reasons: First it removes too much of your natural oils, second, hot water brings blood circulation to your skin which is why your skin turns red like a lobster. With the circulation comes inflammatory building blocks to create more itch and even a rash. Water temperature should be tepid, meaning skin temperature or just a little warmer—especially if you have fragile skin that’s prone to dryness. You shouldn’t shower for more than 5 to 10 minutes, and use a non-drying soap only on the oily and odor-causing parts of your skin such as your face, armpits, buttocks, groin, and feet. Try not to soap your arms or legs. Sebaceous Gland are microscopic exocrine glands in the skin that secrete an oily or waxy matter, called sebum, to lubricate and waterproof the skin and hair of mammals. In humans, they occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of the hands and soles of the feet. The type of secretion of the sebaceous glands is referred to as holocrine. Cleaning Hair with Just Water

2. Give Off the Natural Scent
When talking about giving off your natural scent, it is important to clarify that this should only be obvious when someone gets close to you; if they can smell you from far away you should consider switching deodorants. Experts have linked smell with sexual attraction as well as selecting a mate both on the physiological and psychological level. This means that by showering less, you may actually do better at attracting a partner.

3. Preserve Helpful Bacteria
Most people realize that our stomachs need good bacteria to function but not everyone realizes that this is true of the skin cells as well. The New York Times had an article in which Dr. Richard Gallo who is the dermatology chief at the University of California pointed out that good bacteria in the skin cell help these cells learn how to produce their own antibiotics that can help protect us from bad bacteria. Body lotion and most soaps don’t provide this benefit; only showering less frequently does.

4. Protect from Harmful Chemicals
You may be surprised to learn that having oils and dead skin cells on your skin is actually beneficial. These elements provide a kind of protection from harmful bacteria. They also make it more difficult for certain chemicals to penetrate the skin. This is crucial as these chemicals can damage the skin and in some cases other parts of the body as well. When you shower, you remove these oils and dead skin cells from your skin and in the process make it easier for chemicals to get in. this is even worse if you are using harsh soaps or body washes that contain chemicals. Because of this, experts suggest always selecting a nontoxic soap with a minimal number of ingredients and only using it when necessary and in the locations that truly need it.

5. Reduce Skin Irritations
Skin irritations are fairly common and people who deal with these issues such as rashes, general irritation or even something specific such as rosacea and eczema know that taking hot showers makes the problem worse. In fact, their Skin tends to behave better when they take fewer hot showers. Some people with psoriasis, eczema or other similar conditions will actually be allergic to the sensitizers found in shampoos and soaps. If you remove these toxic products from your routine, you are likely to notice a significant decrease in rashes and irritations. Some people will even see their problems completely disappear.

Proper Moisturizing Protocol
Try not to wait longer than 3 minutes after leaving the shower to moisturize your skin. After stepping from the shower, gently pat excess water from your skin, leaving some droplets behind. Then apply a liberal amount of a moisturizer that contains ceramide (a natural oil found in skin). When skin gets dry and cracks, it lets in bacteria and allergens.

Moisturizer are complex mixtures of chemical agents (often occlusives help hold water in the skin after application, humectants attract moisture and emollients help smooth the skin.) specially designed to make the external layers of the skin (epidermis) softer and more pliable. They increase the skin's hydration (water content) by reducing evaporation. Naturally occurring skin lipids and sterols, as well as artificial or natural oils, humectants, emollients, lubricants, etc., may be part of the composition of commercial skin moisturizers. They usually are available as commercial products for cosmetic and therapeutic uses, but can also be made at home using common pharmacy ingredients. Mechanisms of actionare Occlusives: These work by forming a thin film on the surface of the skin to prevent loss of moisture. Humectants: These attract water vapor from the air to moisturize the skin. Restoration of deficient materials: These are more complex and try to restore natural moisturizing factors on the skin, such as amino-lipids. Antipruritic action (anti-itching): Down regulate cytokines and cooling effect from evaporation of water for water-based moisturizer. Antimitotic (mitoic inhibitor): Slow the process of mitosis (cell division) on the epidermis by mineral oil, which could be helpful for people who have psoriasis disease. UV Protection: Moisturizers also contain sunscreen which will protect your skin from UV light. Inhibit proinflammatory prostanoids production: Blocking cyclooxygenase activity which causes soothing and lower skin inflammation. Wound healing: Hyaluronic acid, Antimicrobial effect by act against microbe surface. Xeroderma. Two factors have to be considered when assessing the safety of a moisturizer: The safety of the ingredients it contains and The risk of bacterial contamination. Some people are sensitive or allergic to certain chemical components, which can cause irritation, rashes, and other allergic reactions. As with most skin-care products, there is a risk of moisturizers being contaminated with bacteria that can cause disease.

Oil is any neutral, nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (immiscible with water, literally "water fearing") and lipophilic (miscible with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and surface active.

Humectant is a hygroscopic substance used to keep things moist; it is the opposite of a desiccant. It is often a molecule with several hydrophilic groups, most often hydroxyl groups; however, amines and carboxyl groups, sometimes esterified, can be encountered as well (its affinity to form hydrogen bonds with molecules of water is the crucial trait).

Lubricant is a substance, usually organic, introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking (oils and fats in use in frying pans, in baking to prevent food sticking), bioapplications on humans (e.g. lubricants for artificial joints), ultrasound examination, medical examination.

Cold Shower
Take more cold and cool showers then hot and warm showers. If you do take a occasional hot shower, the last couple of minutes of your shower should be cold water. Ending your shower with cold water will help lock in moisture, increase circulation, and benefit your skin and hair. Cold temperature decreases Transepidermal Water Loss, contributing to better skin hydration. Cold temperature also reduces your skin’s sensitivity to irritants. A chilled end to your shower may “cause superficial blood vessels to constrict, which can be beneficial to those who are prone to facial flushing or rosacea. Due to decreased facial redness, the skin tone/complexion may appear improved. Cold showers also speed up sore muscle recovery. Cold temperature also redirects blood flow to deep blood vessels, improving blood flow to the heart. This improved blood return may help the body’s metabolism and processing of waste products. Lymphatic System. Cold water also increases your heart rate, so it wakes you up. Cold water can also improve your mood. Cold water could also increase your stores of brown fat (the “good” fat that burns calories/energy in order to produce heat) Cold water should not be so cold that it causes discomfort.

Take short showers if you shower more than once a day. Don't stand under water for minutes at a time. Hot water strips away natural oils and damages the skin faster, so stick to a lukewarm or cooler shower.

Hair is made of dead skin cells and doesn't need as much washing as the rest of our skin. Wash your scalp at least weekly and
wash your face, chest and back after conditioning the Hair.
Dry Hair Shampoo - Shaking corn starch into hair has achieved the same effect, but most current products deliver the drying agents via an aerosol spray.

Conditioner-Only Hair Washing or Co-Washing is the process of only using conditioner to wash, condition, and moisturize your hair. According to experts, conditioner is more gentle on the hair and still lifts dirt and product from strands, as a shampoo would. It must be a silicone-free conditioner to keep from weighing your hair down. Add a cleansing conditioner to your routine if your hair is dry.

You want to soften the hair before shaving, but not too much. Shaving should happen at the end of a short shower so the hairs are damp but not too swollen from too much heat and steam, which causes hair swelling that later leads to Ingrown Hair  when the shaved hairs dry and shrink below the skin surface. Pat your skin with a towel instead of rubbing vigorously. Apply moisturizer right away, within two to three minutes of showering.

Messaging the Skin


Sweat


Perspiration is the production of fluids secreted by the sweat glands in the skin. Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. Exocrine Gland are glands that produce and secrete substances onto an epithelial surface by way of a duct. Hydration

Sweat Gland are small tubular structures of the Skin that produce sweat. Sweat glands are a type of exocrine gland, which are glands that produce and secrete substances onto an epithelial surface by way of a duct. There are two main types of sweat glands that differ in their structure, function, secretory product, mechanism of excretion, anatomic distribution, and distribution across species: Echini Sweat Glands are distributed almost all over the human body, in varying densities, with the highest density in palms and soles, then on the head, but much less on the trunk and the extremities. Its water-based secretion represents a primary form of cooling in humans. Apocrine sweat glands are mostly limited to the axilla (armpits) and perianal areas in humans. They are not significant for cooling in humans, but are the sole effective sweat glands in hoofed animals, such as the camels, donkeys, horses, and cattle. Apocrine Sweat Gland is a type of merocrine sweat gland composed of a coiled secretory portion located at the junction of the dermis and subcutaneous fat, from which a straight portion inserts and secretes into the infundibular portion of the hair follicle. In humans, apocrine sweat glands are found only in certain locations of the body: the axillae (armpits), areola and nipples of the breast, ear canal, eyelids, wings of the nostril, perianal region, and some parts of the external genitalia. Modified apocrine glands include the ciliary glands in the eyelids; the ceruminous glands, which produce ear wax; and the mammary glands, which produce milk. The rest of the body is covered by eccrine sweat glands. Sweat Glands are small tubular structures of the skin that produce sweat. Ceruminous glands (which produce ear wax), mammary glands (which produce milk), and ciliary glands in the eyelids are modified apocrine sweat glands.

Gland is a group of cells in an animal's body that synthesizes substances (such as hormones) for release into the bloodstream (endocrine gland) or into cavities inside the body or its outer surface (exocrine gland).

Pore is any tiny hole admitting passage of a liquid, fluid or gas. Any small opening in the skin or outer surface of an animal.

Heat Index is an index that combines air temperature and relative Humidity, in shaded areas, as an attempt to determine the human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade. Sometimes feeling like it's 30 degrees hotter then the actual temperature. The result is also known as the "felt air temperature" or "apparent temperature". For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F). This heat index temperature has an implied (unstated) humidity of 20%. This is the value of relative humidity for which the heat index formula indicates 41 °C feels like 41 °C. A heat index temperature of 32 °C has an implied relative humidity of 38%. The human body normally cools itself by perspiration, or sweating. Heat is removed from the body by Evaporation of that sweat. However, high relative humidity reduces the evaporation rate. This results in a lower rate of heat removal from the body, hence the sensation of being overheated. This effect is subjective, with different individuals perceiving heat differently for various reasons (such as obesity, metabolic differences, pregnancy, menopause, effects of drugs and/or drug withdrawal); its measurement has been based on subjective descriptions of how hot subjects feel for a given temperature and humidity. This results in a heat index that relates one combination of temperature and humidity to another. Because the humidity index is based on temperatures in the shade, while people often move across sunny areas, then the heat index can give a much lower temperature than actual conditions of typical outdoor activities. Also, for people exercising or active, at the time, then the heat index could give a temperature lower than the felt conditions. For example, with a temperature in the shade of only 82 °F (28 °C) at 60% relative humidity, then the heat index would seem 84 °F (29 °C), but movement across sunny areas of 102 °F (39 °C), would give a heat index of over 137 °F (58 °C), as more indicative of the oppressive and sweltering heat. Plus when actively working, or not wearing a hat in sunny areas, then the feels-like conditions would seem even hotter. Hence, the heat index could seem unrealistically low, unless resting inactive (idle) in heavily shaded areas. Heat Index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature. A quantity expressing the discomfort felt as a result of the combined effects of the temperature and humidity of the air. Bodies lose heat in water very fast due to the big heat capacity of water.

Heat Exhaustion - Exercising (sweat)

New microfluidic devices help athletes and enhance physical rehab. A new wearable system measures sweat and sweat biomarkers. It is a soft, flexible device that measures the bodies’ response to exercise.

Wearable device measures cortisol in sweat. By drawing in a bit of sweat, a patch can reveal how much cortisol a person is
producing. Cortisol is known as the stress hormone but is involved in many important physiological functions.

Chloride compounds or chlorine atoms, often attached to sodium ones to form salt – are important for maintaining the body’s internal pH balance, regulating the movement of fluids in and out of cells, and transmitting impulses across nerve fibres. Also mixed in with sweat is urea, ammonia, proteins, sugars, potassium and bicarbonate. Not to mention trace metals like zinc, copper, iron, nickel, cadmium, lead, and even a tiny bit of manganese. For some of those metals, sweat is an important mechanism for excreting them from inside of the body. Sweat exits the body through one of two types of glands. Apocrine glands are found in the armpits and nostrils and on the nipples, ears and parts of the genitalia Eccrine Glands, millions of which are distributed over most of the rest of the human body When the body and skin get too warm, thermoreceptors send a message indicating as much to the brain. There, the hypothalamus – a small cluster of cells that controls our hunger, thirst, sleep, and body temperature – sends a message to the apocrine and eccrine glands, which begin pumping out sweat. Perspiration left behind on your skin can allow bacteria to grow, so you may need a shower after strenuous exercise or work.

Don't Sweat the Small Stuff (worrying)

Body Oder

Body Odor is present in animals and humans, and its intensity can be influenced by many factors (behavioral patterns, survival strategies). Body odor has a strong genetic basis both in animals and humans, but it can be also strongly influenced by various diseases and physiological conditions. Body odor is generally considered to be an unpleasant odor among many human cultures. In humans, the formation of body odors is caused by factors such as diet, gender, health, and medication, but the major contribution comes from bacterial activity on skin gland secretions.

Pheromones (sense of smell). - Why I don't smell my own Stink?

Diet quality and the attractiveness of male body odor. Greater fruit and vegetable intake, was significantly associated with more pleasant smelling sweat (with more floral, fruity, sweet and medicinal qualities),and greater carbohydrate intake with stronger smelling less pleasant sweat.

Ammonium Aluminium Sulfate, also known as ammonium alum or just alum, is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH4)Al(SO4)2·12H2O. It is used in small amounts in a variety of niche applications. The dodecahydrate occurs naturally as the rare mineral tschermigite. Ammonium alum is made from aluminium hydroxide, sulfuric acid and ammonium sulfate. It forms a solid solution with potassium alum. Pyrolysis leaves alumina. Such alumina is used in the production of grinding powders and as precursors to synthetic gems. Ammonium alum is not a major industrial chemical or a particularly useful laboratory reagent, but it is cheap and effective, which invites many niche applications. It is used in water purification, in vegetable glues, in porcelain cements, in deodorants and in tanning, dyeing and in fireproofing textiles. The pH of the solution resulting from the topical application of ammonium alum with perspiration is typically in the slightly acid range, from 3 to 5. Ammonium alum is a common ingredient in animal repellant sprays. Alum was once a common pickling ingredient used to promote crispness in preserved vegetable, due to the way it reacts with natural pectin. It has fallen out of use from a suspected link to Alzheimer's Disease, and is no longer recommended for pickling. Aluminium sulfate, closely related to ammonium alum, is considered nontoxic up to LD50 of 6207 mg/kg. For reduced concentrations no human or ecological toxicity officially registered.
