Facts about human skin that you should know

Many think that the facts about the skin only resemble the problem of acne, red rash, and other skin diseases. But did you know that the skin has an important role in the human body? Come on, see an explanation of the following important facts about skin.

Some facts about human skin

1. The skin is the largest organ of the body

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 adult skin is about 1.73 square meters in length and width, and serves to cover bones and humans. Then, your body weight is affected by 16% of your total skin weight.

2. The skin plays an important role in regulating body temperature

Did you know that the skin plays an important role in regulating the human body temperature? In fact, it is true that the skin functions as the body's thermostat, and functions to regulate the sweat glands to cool the body when the weather is hot.

Under normal conditions, usually 1 liter of sweat per day. In addition, when you are in very cold temperatures, the blood vessels in the skin will tighten on their own and limit the amount of blood reaching the surface of the skin. This is intended to prevent heat loss in the body.

The pores on the skin will also shrink automatically when it is in a cold temperature, so that your body does not feel extreme cold.

3. Skin color is made of a pigment called melanin

Why is it that sometimes the skin color can suddenly become bright and sometimes pale? Basically, human skin color is produced by the melanin pigment in the body. Every human being has the same number of cells to produce melanin, and it is made up by the epidermal layer of the skin. However, the more your body produces melanin, the darker your skin will be.

Have you ever been confused, why if you get dark your skin color? According to the Journal of the American Medical Association, sun exposure causes the body to produce more melanin to protect the skin from UV (ultra violet) rays. It's not uncommon if you bask in the sun, your skin gets a little dark and red. This is one of the protection of skin melanin against the dangers of UV rays produced.

4. Millions of bacteria live on the skin

The surface of the skin on the human body is infested with various bacteria, and is generally known as the skin microbiota. These bacteria usually thrive because humans neglect or rarely clean the accumulated dead skin cells.

It's a good idea to regularly exfoliate (remove dead skin cells) on the skin to get a clean bright skin tone. Andre Bank recommends, if your skin is a sensitive type, exfoliate once a week using oatmeal to prevent acne and bacteria from coming to the surface of the skin.

5. Dust actually consists of dead skin cells

Dust is a result of the fact that skin is made of dead skin cells. Usually, the skin will peel off by itself once every 28 days and blend into dust. Not only that, dust is also made of other factors such as sand, animal hair, insects and finally your skin that dies and peels off by itself.
