Ten Less-Known Fascinating Facts About Your Skin
Skin varies in type, color and texture from one person to another; but despite this divergence, everyone’s skin serves one main purpose, and that is: to protect the inside of the body. People are quite conscious of skin on some locations of the body, especially the more visible ones, like facial skin and the skin of your arms and legs. Generally though, we think of skin as something that’s always been there since we were born and as long we take reasonable care of it, it will continue to function as it should. Thus, in a sense, skin is probably one of the most taken-for-granted parts of the human body and most people know very little about skin. Here are some fascinating basic facts about your skin that not so many people know about.
10. Largest organ.
Skin is the body’s largest organ (no matter if Maxim readers think otherwise) and accounts for 12 – 16% of the total body weight. The average adult skin extends to about 20 – 21 square feet and weighs from 6 to 9 lbs, which is almost twice as much as the brain weighs.
9. Skin composition.
The skin is composed of approximately 300 million skin cells. Each square inch has an estimated 72 feet of nerve fibers, which when put together totals to about 45 miles or 72 kilometers of nerves in the skin. Every half square inch of the human skin has more or less 100 sweat glands, 10 hairs, 15 sebaceous glands, and 3.2 ft of tiny blood vessels (in effect, the entire skin system has a total of 11 miles of blood vessels).
8. Humans shed skin, too.
Your house pet isn’t the only creature in your household with shedding issues. Did you know that humans shed around 600,000 particles of dead cells from the skin surface every hour without even realizing it? That amounts to an equivalent 1.5 lbs per year. This means that by the time an average individual reaches the age of 70, he or she would have lost 105 lbs of skin.
7. Skin as dust.
Given that the skin can shed that much quantity of dead cells, where do you think those skin flakes go? You guessed right. They’re everywhere. Seventy to ninety percent of dust in a single household is made up of dead skin cells shed by humans. In a global perspective, dead skin accounts for about a billion tons of dust floating in the atmosphere at any given moment.
6. Skin regeneration.
The good thing about it is, if the skin can shed so many flakes, it is also capable of re-growing new outer skin. The skin is constantly renewing from the bottom up every 27 or 28 days totaling 1,000 new skins in a lifetime.
