Some cool skin facts

Introduction and background

Our skin has always been an object of mesmerization for scientists, researchers and therapists for hundreds of centuries.  People from ancient civilisations such as those of Greece, Rome and Egypt was almost obsessed by the value and beauty of their skins. For the same reason, we find countless depictions of skin and skin related phenomena in art, culture and history. The following article is intended to highlight some of the very cool (interesting) facts about our own human skin. Read on to discover:


Some cool skin facts

  • There are two types of skin on the basis of hair distribution i.e. hairy skin (our whole body excluding soles of the feet and palms of our hands) and skin of our soles and palms.
  • Skin is the largest “organ” of our body with respect to the body area it covers.
  • Skin comprises about 15% of our total body weight.
  • Believe it or not, skin actually performs some really functions such as excretion of waste materials, salt and water (in the form of sweating) and also temperature regulation.
  • An average size of the skin of an adult human being is 21 Sq ft.
  • Our skin continuously regenerates its cells. What it means is that older cells are shed away and are replaced by the new ones.  The whole process may take up to 77 days, on an average. The same phenomenon is also related with  scarring and healing of wounds and dead cells.
  • The above-mentioned process of “skin-shedding” is interesting.  It is estimated that by the age of 70, an average human adult has lost up to 105 pounds of skin.
  • This “dead skin or dead skin cells” make up the billions of tons of dust in our atmosphere.
  • Similarly, most of the dust found in our homes actually comprises of the same dead skin cells that we shed on regular (daily) basis.
  • The so called “goose bumps” are actually tiny, microscopic pimples that are permanently present on our skin and become “erect” due to the sensory nerve endings that are present in various skin layers whenever we are excited or frightened.
  • On an average, each half square inch of our skin has up to 10 hairs, depending on the site and part of our body.
  • Our skin has three major layers i.e. epidermis (the outermost or superficial layer), the dermis  (the middle one) and hypodermis (or subcutis) the innermost or deepest layer of our skin.
  • Our skin is even present in our eyelids. However, it is the thinnest there.
  • Our skin swells up a little whenever it absorbs water.
  • Our skin actually protects our body from germs, bacteria, viruses, fungi, parasites and other foreign invaders.
  • Our skin is one of the most “sensitive” organs of our bodies that is can be easily “hypersensitive” (or allergic) to any foreign substance.
  • One of the most important functions of our skin is that of “sensory function”. It helps us feel the temperature (hot or cold) and texture of a particular object with the help of  touching.
  • At the same time, our skin is also very much prone and vulnerable to common diseases such as acne.
  • Acne is one of commonest skin disorders in the world that can affect both genders with the same intensity.
  • Most of the skin diseases have a profound impact on one’s psychophysical and mental status because of the “appearance” effect.
  • Contrary to the popular belief or myth, most of the skin diseases can actually be completely cured or controlled by practising simple measures and tips.
