What does skin do? The most important function of skin is a protective one. It is the main barrier between the environment and the internal organs of the body, shielding them from injury, bacteria, chemical invasion and the harmful rays of sunlight. The skin is a sensory organ containing many cells that are sensitive to touch, temperature, pain, pressure and itching. It also plays a role in regulating temperature. The skin secretes sebum (normal oil produced by skin) and sweat through glands and absorbs creams through pores. Use the skin structure overhead to highlight the structure of skin. Focus soley on the three layers of skin. The skin consists of 3 main layers: - epidermis is the outer protective layer - dermis is the supporting structure of skin - subcutaneous tissue is a fatty tissue layer below the dermis that pads and insulates.

<span style="font-family: 'Century Gothic','sans-serif';">One of the most effective ways we have to protect ourselves and others from illness is good personal hygiene. This means washing your hands, especially, but also your body. It means being careful not to cough or sneeze on others, cleaning things that you touch if you are unwell, putting items such as tissues (that may have germs) into a bin, and using protection (like gloves or condoms) when you might be at risk of catching an infection. Personal hygiene, such as bathing, is very much dependent on the culture in which you live. In some cultures, it is expected that you will wash your body at least every day and use deodorants to stop body smells. Other cultures have different expectations.
 * <span style="font-family: 'Century Gothic','sans-serif';">Body odour **<span style="font-family: 'Century Gothic','sans-serif';">Body smells are caused by a number of factors working in combination, including:
 * <span style="font-family: 'Century Gothic','sans-serif';">Chemicals in sweat, including pheromones, which are made by the body and sexually attract (or repel) other people.
 * <span style="font-family: 'Century Gothic','sans-serif';">Wastes excreted through the skin.
 * <span style="font-family: 'Century Gothic','sans-serif';">The actions of bacteria that live on the skin and feed on dead skin cells and sweat.
 * <span style="font-family: 'Century Gothic','sans-serif';">Unwashed clothes, such as underwear and socks.


 * <span style="font-family: 'Century Gothic','sans-serif';">Hand washing **<span style="font-family: 'Century Gothic','sans-serif';">Most infections, especially colds and gastroenteritis, are caught when we put our unwashed hands, which have germs on them, to our mouth. Some infections are caught when other people’s dirty hands touch the food we eat. Hands and wrists should be washed with clean soap and water, using a brush if your fingernails are dirty. Dry your hands with something clean, such as paper towels or hot air dryers. You should always wash your hands:
 * <span style="font-family: 'Century Gothic','sans-serif';">After using the toilet
 * <span style="font-family: 'Century Gothic','sans-serif';">Before making or eating food
 * <span style="font-family: 'Century Gothic','sans-serif';">After handling dogs or other animals
 * <span style="font-family: 'Century Gothic','sans-serif';">If you have been around someone who is coughing or has a cold.
 * <span style="font-family: 'Century Gothic','sans-serif';">Personal hygiene for women **<span style="font-family: 'Century Gothic','sans-serif';">The vagina is able to clean itself no special care is needed, other than washing the external genitals. Here are some personal hygiene suggestions for women:
 * **<span style="font-family: 'Century Gothic','sans-serif';">Menstruation **<span style="font-family: 'Century Gothic','sans-serif';"> - wash your body, including your genital area, in the same way as you always do. Change tampons and sanitary napkins regularly, at least four to five times a day. Always wash your hands before and after handling a tampon or pad.
 * **<span style="font-family: 'Century Gothic','sans-serif';">Thrush **<span style="font-family: 'Century Gothic','sans-serif';"> - some soaps and detergents can irritate the skin of the vagina, and make thrush infections more likely. Some people find that they often get thrush when they use antibiotics. Use mild soap and unperfumed toilet paper. Avoid tight, synthetic underwear. Try cotton underwear, and change regularly. There is medical treatment for thrush, so talk to your doctor or pharmacist.
 * **<span style="font-family: 'Century Gothic','sans-serif';">Personal hygiene for men **<span style="font-family: 'Century Gothic','sans-serif';">A build-up of secretions called smegma can form under the foreskin of uncircumcised men. If you are uncircumcised, gently pull back the foreskin when you have a shower and clean with water. You can use soap if you like, but make sure you rinse it off well.**Bad breath**Good dental hygiene includes regular brushing and flossing. Bad breath can be caused by diseases of the teeth, gums and mouth, such as infections. Most people have bad breath first thing in the morning because saliva is not made while you’re asleep. Some foods that can cause bad breath include garlic and onion. Mouth washes, mouth sprays and flavoured chewing gum can make your breath smell better for a while, but if you have a health problem in your mouth, you need to see your dentist.
 * <span style="font-family: 'Century Gothic','sans-serif';">Things to remember **
 * <span style="font-family: 'Century Gothic','sans-serif';">Good personal hygiene is one of the most effective ways to protect ourselves and others from many illnesses, such as gastroenteritis.
 * <span style="font-family: 'Century Gothic','sans-serif';">Wash your hands regularly, especially before preparing or eating food and after going to the toilet
