The skin is the largest organ in the human body obviously and most things that happen to us basically gets through the skin. But apart from these common facts, what else do you know about your skin? Here are 8 Amazing Facts About Our Skin
1. There are four main receptors in the skin that respond to pressure: Meissner’s corpuscles, Merkel’s discs, Ruffini endings, and Pacinian corpuscles. Each receptor responds to a different type of touch. “Meissner responds to light touch, Merkel to pressure and texture, Ruffini to stretching, and Pacinian to vibration and deep pressure,” Dr. Bank says. Additionally, there are countless free nerve endings in the skin that gauge pain and temperature.
2. Skin plays an important role in regulating body temperature. Your skin acts as your body’s thermostat. When temperatures rise, sweat glands activate to cool the body down. “Sweating is a bodily function that helps regulate your body temperature” Bank says. “Normal sweating can be as much as a quart of fluid per day.” When temperatures are lower, blood vessels in the skin tighten and limit the amount of hot blood that can reach the skin, preventing heat loss. Pores also become smaller when exposed to colder temperatures in order to retain heat, Bank says.
3. Skin gets its color from a pigment called melanin. Skin color can range from very pale to very dark, depending on how much melanin the body makes. Everyone has the same amount of cells that produce melanin, which is made in the outer layer of the skin called the epidermis; but not everyone produces the same amount. The more melanin your body produces, the darker your skin.
4. Your skin regenerates itself. “Your skin sheds its dead skin cells on a daily basis, creating a new layer of skin every 28 days,” Bank says. “Even while you sleep, Mother Nature is doing her job by making sure your skin exfoliates itself, without your help.” That said, dead skin cells can remain on the skin, so it is important to remove them with an additional exfoliator
5. Dust is partly made up of dead skin cells. Dust is an accumulation of many materials, including dirt, animal dander, sand, insect waste, and even dead skin cells. “In fact, each time you vacuum, you’re picking up dead skin cells off the floor, the chair, and the walls,” Bank says.
6. Millions of bacteria live on the skin. “The skin’s surface is home to surprisingly diverse communities of bacteria, collectively known as the skin microbiota,” Banks says. “The harmless bacteria that thrive on the skin can help immune cells fight disease-causing microbes.”
7. Changes in the skin can reveal a lot about your health. Changes to the skin can be a sign that something is wrong. Rashes, hives, and itching may signal an allergic reaction, a bacterial skin infection, a viral infection, or an autoimmune disease. A mole may be a sign of skin cancer
8. Pimples are not caused by dirt or diet. These are common misconceptions, Bank says, but there are some common culprits that can offset breakouts. “Acne can be caused or aggravated by menstruation and/or pregnancy due to changes in hormone levels, sweating, humidity, some medications, and certain cosmetics or hair preparations,”
