PRE-INSTRUCTIONAL ACTIVITY

Vocabulary

epidermis - skin has two main layers / the top layer, called the epidermis, is a tough, waterproof barrier / it holds moisture inside your body and keeps germs out / germs can't pass through your skin unless the epidermis is broken; that's why it's important to wash cuts and scrapes and keep them clean until they heal

dermis - skin has two main layers /  the bottom layer, called the dermis, is thicker than the epidermis, and it contains blood vessels, nerve endings, and oil glands

oil glands - contained in the dermis (bottom layer of skin), oil glands make oil that helps soften your skin and reaches the surface of your skin through openings called follicles

sweat glands - structures in the dermis (bottom layer of skin) that produce sweat

pores - openings in the skin through which sweat travels to reach the skin's surface

sunscreen - a lotion or cream that protects your skin from the sun's harmful rays / sunscreen containers list the Sun Protection Factor (SPF), a number between 2 and 50 / the higher the number, the more protection the sunscreen will give you

READ: Your Skin & Its Care


Your bones hold you up. Your muscles help you move. Your heart pumps your blood. All these important organs are enclosed and protected by your largest organ—your skin. Taking care of your skin helps your skin take care of you.


What is your skin?


As the diagram below shows, skin has two main layers. The top layer is called the epidermis. The epidermis (eh•puh•DER•muhs) is a tough, waterproof barrier. It holds moisture inside your body and keeps germs out. Germs can't pass through your skin unless the epidermis is broken. That's why it's important to wash cuts and scrapes and keep them clean until they heal.

The top of the epidermis is made of dead skin cells that flake off easily. This hardened layer of cells prevents germs from entering your body. The lower cells of the epidermis rapidly divide to make new cells. In time the lower cells die and are pushed toward the surface. As the top skin cells flake off, the new cells from below replace them.


The bottom layer of skin is called the dermis. The dermis (DER•muhs) is thicker than the epidermis, and it contains blood vessels and nerve endings. It also contains oil glands. Oil glands make oil that helps soften your skin. Oil reaches the surface of your skin through openings called follicles.


Sweat is produced by structures called sweat glands in the dermis. Sweat reaches the skin's surface through openings called pores. You sweat the most when you are hot because sweat helps cool your body. Sweat changes from a liquid to a gas in a process called evaporation. Evaporation takes energy. The energy for sweat evaporation comes from the heat of your body. So your body loses heat and cools as sweat evaporates.


You might be surprised to learn that your hair and nails are also made of dead skin cells. Hair and nail cells form deep inside your skin. A strand of hair is a narrow stack of dead skin cells piled one on top of the other. A fingernail or toenail is a broad, flat sheet of dead skin cells. Your hair and nails grow because new cells push against the dead cells from below.


How can you take care of your skin?


Keeping your skin clean is one of the best ways to help it stay healthy. If your hands and face are dirty, germs might enter your body when you touch your eyes, nose, or mouth. Germs that cause colds and flu are often spread this way.


When you wash your hands, germs you have picked up from things you've touched are rinsed away. It's important to wash your hands after blowing your nose and after sneezing or coughing into your hands. Also, wash your hands after you go to the bathroom or handle anything that is dirty. If you touch an animal, wash your hands afterward. Always wash your hands just before you handle or eat food.


When you wash your hands, rub them all over with soap and warm water. Squeeze the suds between your fingers. Wash the skin on your knuckles and around your fingernails. Get underneath your nails, too, because dirt and germs tend to build up there. Use a nailbrush to do a thorough job. Then rinse your hands well to wash away the dirt and germs. You can use lotion if your hands feel tight and dry after washing.


Wash your face at least twice a day. Most people wash their faces before going to bed and after waking up. Use soap, warm water, and a clean washcloth. Having a clean face helps you look good and feel good about yourself.


Bathing also helps you look and feel refreshed. If you are very active, take a bath or shower every day. When the weather is cold and dry, you might bathe every few days instead so your skin won't get too flaky or itchy. Wash your hair with shampoo when it begins to look or feel dirty. Some people need to wash their hair daily. Others can go for several days without shampooing.


Washing is not the only way to take care of your skin. You also need to protect your skin from the sun. Sunlight can harm your skin. It can cause your skin to burn, dry out, and wrinkle. Over time, too much sun can cause a serious disease called skin cancer.


Sunscreen is a lotion or cream that protects your skin from the sun's harmful rays. Sunscreen containers list the Sun Protection Factor (SPF), a number between 2 and 50. The higher the number, the more protection the sunscreen will give you. If possible, stay out of the strongest sun, between 10:00 A.M. and 3:00 P.M., to protect your skin. Protecting your skin from sun now will help you have healthy skin all your life.


REMEMBER...Taking care of your skin is important for your health. Understanding how your skin protects you can help you make good choices about caring for it.
