CATEGORIES AND MORE ON SCIENTISTS //sweat:// interior coolant why do we sweat? when we work out, the muscles generate too much heat and our bodies need to be cooled down in order to keep functioning. (also happens when temperatures reach the 90's). temperature-sensing nerves in the skin and brain tell the body to release water to cool us.

 * a nerve sends a signal from the brain to the sweat gland, telling it to release sweat

when does the brain send a signal via the nerve to the sweat gland?
 * when the nerves in the skin detect temperature and send a signal to the brain that the skin it hot
 * when the skin is at a temperature in the 90s
 * whether the heat source is
 * internal: muscles contract and generate heat

two million - 4 million sweat glands, depending on the human
 * bigger sweat glands mean more sweat
 * they are more sensitive to nerve stimuli

women sweat more than men obese people may differ
 * especially during menopause, ovulation
 * 1) fat may insulate the interior
 * 2) compromises heat transfer
 * 3) grow more sweat glands

global warming: what will happen to our sweat glands? //acclimation//
 * at first, sweat more and lose more salt and water
