The Skin

Skin is the body’s largest organ and accounts for about 15% of your body weight. The average adult has approximately 21 square feet of skin, which weighs 4 kgs and contains more than 17.5 kms of blood vessels. The average person has about 300 million skin cells and a single square inch of skin has about 19 million cells and up to 300 sweat glands.

Skin is one of the most important organs of the human body and acts as your body’s thermostat besides being the protective barrier for the human body. When temperatures rise, sweat glands activate to cool the body down. The skin’s surface is home to surprisingly diverse communities of bacteria, collectively known as the skin microbiota. The harmless bacteria that thrive on the skin can help immune cells fight disease-causing microbes.

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.

It’s important to visit a Skin Specialist / Dermatologist if you start observing any unexplained changes to your skin.
