Human Armor: Our Amazing Skin
When we look at God’s wonderful world, we see many marvelous things He created. Sometimes, we do not realize just how amazing God’s designs are. For instance, have you ever taken time to think about how important and valuable skin is?
Just think about all the different kinds of skin. Human skin is thin and mostly smooth. Sharkskin is rough and feels like sandpaper. Elephant skin is thick. Many reptiles have scaly skin. God made all these different types of skin to help humans and animals survive. Let’s look at some amazing skin.
Take a minute to look at your arms and hands. Did you know that the skin you see is busy protecting you even though you are not thinking about it? Your skin covers your body and protects your internal organs from harmful germs. Special cells in your skin act as “security guards.” When these little guys detect bad germs that are trying to get in, they tell your body to make cells that fight the germs.
Not only does your skin protect you, but it also helps keep your body the right temperature. What happens when you run fast, or play a game of tag? That’s right, you sweat. Did you know that your skin produces sweat and moves it to the outside of your body? When the air around you causes the sweat to evaporate, it cools you down so you don’t overheat.
Your skin also works like a factory. When the Sun shines on your body, your skin tells your body to make vitamin D. This vitamin is very important. It helps keep your body healthy and your bones strong. Without the vitamin D that your skin helps produce, your bones would get soft and break easily.
The cells in your body need water in order to work correctly. Your skin holds water inside your body so your cells can do their jobs. Without your skin, the water that you drink would evaporate into the air and your body would dehydrate (a fancy word that means “dry out”).
