THE SKIN SECRETS

Less than a millimeter thick in places,the skin is composed of three layers.The outermost layer is the bloodless epidermis.The dermis includes collagen,elastin and nerve endings.The innermost layer,subcutaneous fa,contains tissue that acts as anenergy source,cushion and insulator for the body.

    It is the skin that provides the sensory stimulation for our body.We can live without hearing or seeing-in fact ,with out any of our other senses.But babies born without effective nerve connections between skin and brain can fall to thrive and may even die.For humans insufficient touching in early years can have lifelong results, “in touching cultures,adult aggression is low,whereas in cultures where touches are limited adult aggression is high” writes Tiffany Field,director of the Toud research institute at the university of Miami school of Medicine.Studies of a variety of cultures show a correspondence between high rates of physical affection in childhood and low rates of adult physical violence.

    The skin has millions of nerve cells of various shapes at different depths.When the nerve cells are stimulated,physical energy is transformed into energy used by the nervous system and passed from the skin to the spinal cord and brain.In simploe terms people perceive  three basic things through skin;pain,temperature,and pressure.

   Over exposure to sun is highly dangerous to skin.repeated sunburn and prolonged exposure to utra violet radiation from sunlight can cause irreppairable damage to the DNA within skin cells and allowing cancerous cells to take root.the colour of the skin depends mainly on melanin a brownish pigment produced by the melanocytes in the epidermis.

    When we age,the skin loses its ability to retain moisture;the dermis loses its elasticity and its collagen stretches;and lines and wrinkles from laughter and other habitual facial expression deepen.Toxins in cigarette smoke accelerate skin-cell aging.
