It is important because if we didn't have this "air conditioning system" then our bodies could overheat or become too cold.

(2) The human body can tolerate cooling. How much? Give examples. Our bodies can tolerate overcooling and recover from degrees below 20.

(3) The human body can not tolerate over heating. How much? Give examples. The human body can not tolerate over heating because the brain will malfunction if our temperature is six or seven of a fever. If our bodies reach 110 or higher, this is considered the upper limit compatible for life.

(4) Why do we think humans evolved sweat glands? Give examples. WE think human evolved sweat glands because body hair was starting to evolve away, which began the growth of an alternative cooling system which are the plentiful sweat glands we have. We needed something to keep us cool from the long sunny days and the active life we had.

(5) Describe some of the variation in the amount of sweat glands. Give examples. The amount of sweat glands varies from person to person based on their age, sex, weight, and shape. Some people have fewer than two million and some have more than four million. People who are heavier than others may have glands five times bigger than others, it all depends on your body shape.

(6) What happens during menopause with respect to sweat? Give examples. During menopause, the sweat glands imagine heat on a woman's body, which is the cause of unnecessary sweat.

(7) What happens as we age? Why is that dangerous? Give examples. As we grow older, we tend to sweat less. This is dangerous because when elders are exposed to extreme heat conditions, for example like now as temperatures in every season are rising rapidly, they don't sweat to cool themselves down. This leads to severe heart strokes.

(8) Is clothing good or bad when it comes to sweat? Why? Give examples. Clothing is good when it comes to sweat because they absorb some of the sweat that would have been caused by the environment. During WWII, a study was shown that soldiers who wore the standard uniform and soldiers who were wearing the standard exercise clothes, the solders with the exercise clothes sweated 30% more than the other soldiers.

(9) Describe what happens during heat acclimation. Give examples. During heat acclimation, the body can adjust to higher temperatures and rev it up to high efficient gear. This is usually seen in athletes who train in very hot temperatures. In the beginning of their training, they sweat mass amounts and tend to feel ill, but when they become used to the temperatures. They still sweat large amounts, but they don't feel ill.

(10) Who is "Adam"? Why is he being used for scientific experimentation? Adam is a mannequin that was built to sweat like human beings. Adam has been used to help reduce fuel consumption by ways to evaluate air conditioner use. He has also been used to evaluate clothes for astronaut to wear under space suits and devices to warm wounded soldiers.
