Diagram Showing the Skin in a Cold Environment . Skin diseases affect 20-33% of the UK population at any one time (All Parliamentary Group on Skin, 1997) and surveys suggest around 54% of the UK population will experience a skin condition in a given year (Schofield et al, 2009). At one point in time, the skin is vasoconstricted, and the skin temperature approaches ambient temperature; a few seconds later, the skin is vasodilated, and its temperature approaches deep body temperature. Sweat from glands in the epidermis also play a role in the body’s fluid balance. A portion of the follicle also contains stem cells capable of regrowing damaged epidermis. When you’re out in cold weather, your skin triggers shivering so the blood vessels will contract and keep you as warm as possible. Body temperature is not homogeneous: deep thoracic, abdominal, and central nervous system (i.e. Binding in moisture when necessary and preventing moisture loss. Skin colors in humans range from extremely fair/light to extremely dark depending on racial/ethnic background, but the density of melanocytes in a given area (e.g. The ultimate multi-tasker, skin plays many other roles essential to our health and well-being. Prevents loss of moisture. Inhibiting the sympathetic center in posterior hypothalamus.
