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.

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.

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.
ndex 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.

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.

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.

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.

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

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. 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 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.

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.

Dermatology is the branch of medicine dealing with the skin, nails, hair and its diseases.

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.

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

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).

Why Should You Not Shower Too Often?

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.

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.   Skin

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.

Cold Shower
After a nice 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.

Cold Shower for Health

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.

Echini Sweat Glands are the major sweat glands distributed over much of the body, found in virtually all skin, with the highest density in palms and soles, then on the head, but much less on the trunk and the extremities.

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. eat GlandSweat Gland are small tubular structures of the skin that produce sweat.

Exercising (sweat)

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.
