(1) Why is sweat like your personal air-conditioner and why is that important? sweat cools your body down when it is hot. It is important because the body cannot suffer high temperatures for long periods of time. Even a fever that is 110 can be deadly. Humans have a resistance to really cold weather but when it comes to hot weather humans are extremely susceptible to overheating and thats why sweat is important. (2) The human body can tolerate cooling. How much? Give examples. The human body can tolerate cooling from 20 degrees below natural temperature which is 98.6F. Hypothermia is an example of extended period of overcooling. (3) The human body can not tolerate over heating. How much? Give examples The brain malfunctions with 6 or 7 degree of overheating. An internal temperature of 110 is life threatening. (4) Why do we think humans evolved sweat glands? Give examples. Humans evolved sweat glands as they lost hair. Humans evolved sweat glands to keep body temperatures down even when one really active in hot heat. Fur hinders the ability to make and produce sweat which is why furry animals dont have sweat glands. (5) Describe some of the variation in the amount of sweat glands. Give examples. Age, sex, genes and weight are all factors of how much a person sweats. People generally have 2 to 4 million sweat glands but people who sweat profusely can have sweat glands five times the average size. (6) What happens during menopause with respect to sweat? Give examples. The bodies thermostat goes a little haywire. Bodies can imagine excessive heat when there is none which causes profuse sweating. (7) What happens as we age? Why is that dangeous? Give examples. Men and women starting at about the age of sixty start sweating less regardless of physical shape. There body cannot keep itself cool enough the elderly are at risk for heat stroke during heat waves and stuff because they cant stay as cool as everyone else. (8) Is clothing good or bad when it comes to sweat? Why? Give examples. Clothing can be good because it blocks direct heat from going on the body. In one test people sitting in the California desert the one near naked wasnt nearly as well off as the other clothed ones because their bodies were absorbing heat from the environment. (9) Describe what happens during heat acclimation. Give examples. During heat acclimation the body is exposed to temperatures hotter than it is used to. They start sweating profusley and lose large quantities of salt in their sweat. Eventually the body reacts to this by cooling skin and internal temperatures. Sweat glands in monkeys almost doubled in size after keeping them at hot temperatures for two weeks. (10) Who is "Adam"? Why is he being used for scientific experimentation? Adam is a mannequin who can sweat and complain like humans and has 120 temperature sensors on his body. He was made to figure out a way to limit using the air conditioners in cars to get better fuel consumption rates. He was used for clothing to see how the human body would react to wearing it and how much and where it would sweat. He helped evaluate clothes for astronauts and soldiers.
