5 Things: Your Skin

I don't think about my skin that much, except on sunny Summer days when I coat myself with sunscreen or when I get the occasional blemish on my chin. More than just a fleshy covering for our muscles, skin is an organ and without it, we would evaporate. Here are five facts you should know about the skin you're in.

  1. Skin, not the liver, is the body's largest organ. Altogether, the skin of an average adult weighs between eight and nine pounds. Skin also grows faster than any other organ. In fact, we are constantly shedding skin cells, to the tune of 50,000 cells every minute.
  2. The skin of an average-sized adult covers 21-square feet and contains over 11 miles of blood vessels. Skin is only 2 millimeters thick. So we are all truly thin skinned. Speaking of thin skin, the eyelids are the thinnest skin of the body and the soles of your feet are the thickest.
  3. On a hot and humid day, your skin can produce up to three gallons of sweat in a 24-hour period. But not all of your body sweats. The nail bed, margins of the lips, tip of the penis, and eardrums do not sweat.

For a couple more cool facts about your skin,


  1. You skin houses at least five types of nerve receptors that respond to pain and to touch. These receptors help keep your brain in touch with the outside world.
  2. Skin does more than just keep the insides of your body inside your body. It also secretes an antibacterial substances to prevent infection, making your skin the immune systems first line of defense. Skin also manufactures the ever important sun shine vitamin — vitamin D, which promotes the absorption of calcium to produce healthy bones.

Hey! Your epidermis is showing. Hope these facts help you appreciate the skin your in.
