Skin Fun Facts
Your skin is your largest organ and plays a vital role in detecting hot and cold, regulating your body temperature and protecting your muscles, bones and internal organs from outside infection and disease. But that’s just for starters. There is so much more to your skin than you might think. Here are some of the most interesting facts about your skin:
- The average person’s skin covers an area of 2 square meters.
- Skin accounts for about 15% of your body weight.
- The average adult has approximately 21 square feet of skin, which weighs 9 lbs and contains more than 11 miles of blood vessels.
