Many assume that the facts about the skin only resemble the problem of zits, red rashes, and other skin diseases. But did you know that skin has an important role in the human body? Come on, see the explanation of the following important facts about the skin.
Some facts about human skin
1. The skin is the body's biggest organ
The skin is the largest organ in the human body. David Bank, a director at the Center for Dermatology and Cosmetic Surgery in New York, said that the skin in adults is about 1.73 square meters in width and serves to cover bones and humans. Then, your body weight is affected by 16% overall skin weight.
2. The skin plays an important role in regulating body temperature
Did you know if the skin plays an important role in regulating the temperature of the human body? In fact it's true that the skin functions as the body's thermostat, and functions to regulate sweat glands to cool the body when the weather is hot.
Under normal conditions, usually sweat comes out to 1 liter per day. In addition, when you are in very cold temperatures, the blood vessels in the skin will tighten by themselves and limit the amount of blood reaching the skin surface. It is intended to prevent heat loss in the body.
Pores on the skin will also shrink by itself when in cold temperatures, so that your body does not feel extreme cold.
3. The color of the skin is made of pigment called melanin
Why sometimes skin color can suddenly be bright and sometimes pale? Basically the color of human skin is produced by the pigment melanin in the body. Every human has the same number of cells to produce melanin, and is made by the epidermal layer on the skin. But, the more the body produces melanin, the darker your skin will be.
Never confused, why if the heat of the skin becomes dark? According to the Journal of the American Medical Association, exposure to sunlight makes the body produce more melanin to protect the skin from UV light (ultra violet). It's not uncommon for you to bask in the sun, the skin becomes a little dark and red. This is one of the safeguards of melanin the skin against the dangers of UV light produced.
4. Millions of bacteria live on the skin
The surface of the skin on the human body is plagued by various bacteria, and is generally known as mircrobiota of the skin. These bacteria usually thrive due to negligent humans or rarely clean up dead skin cells that accumulate.
It's a good idea to routinely exfoliate (remove dead skin cells) on the skin to get a clean, bright skin tone. Andre Bank recommends that, if your skin is of the sensitive type, do one exfoliation per week using oatmeal to prevent acne and bacteria coming to the surface of the skin.
5. Dust actually consists of dead skin cells
Dust is one of the results of facts about the skin made from dead skin cells. Usually the skin will peel itself every 28 days and blend into dust. Not only that, dust is also made of other factors such as sand, animal fur, insects and eventually your skin that dies and exfoliates by itself.
