Sweat is "our interior coolant." Similar to an air-conditioner, it is used to cool down the temperature of the body, drips, and can even stall. Sweat is important because it keeps our body's at a healthy temperature.
 * (1) Why is sweat like your personal air-conditioner and why is that important?**

We can tolerate our body's too much cooling and routinely are able to get back to normal from hypothermic temperatures. We can live through temperatures twenty degrees less than regular body temperature.
 * (2) The human body can tolerate cooling. How much? Give examples.**

We have far less toleration for over heating. The highest limit we can survive at is 110ºF, and any temperature six or seven degrees above normal will cause major brain malfunction.
 * (3) The human body can not tolerate over heating. How much? Give examples.**

Without sweat glands, we would still be like our ape-like ancestors. Sweat glands allow us to have less, thinner hair because we can cool our body temperature.
 * (4) Why do we think humans evolved sweat glands? Give examples.**

Factors that affect the number of sweat glands that a person has include weight, age, sex, and genetics. Therefore, some people have more sweat glands than others just because of various physical factors.
 * (5) Describe some of the variation in the amount of sweat glands. Give examples.**

In menopause, the body falsely recognizes places with heat. The sweat glands then produce excessive amounts of sweat.
 * (6) What happens during menopause with respect to sweat? Give examples.**

As we grow older, we begin to sweat less and less. This is dangerous because older people cannot cool down their body temperature, which can raise their heart rate and put them at higher risk for a heart attack.
 * (7) What happens as we age? Why is that dangeous? Give examples.**

Clothing helps absorb a great deal of external heat, which helps because less heat enters the body and leaves less work for the body to do as far as cooling down the body.
 * (8) Is clothing good or bad when it comes to sweat? Why? Give examples.**

Heat acclimation is when the body has to adapt to higher temperatures so that it can be effective in cooler temperatures. Football players that begin to train in the heat of the summer lose a lot of salt, sweat a lot, and even feel sick.
 * (9) Describe what happens during heat acclimation. Give examples.**

Adam is a life size doll that is supposed to sweat like humans. He used to see how much people sweat, and people use it for studies in air conditioning for cars.
 * (10) Who is "Adam"? Why is he being used for scientific experimentation?**
