How to control BO | A body odor mini quiz
Sweat -- it is the ingenious way our bodies have of keeping us cool during hot weather and strenuous physical activity. As perspiration flows from the 2-4 million sweat glands onto our skin, air blows across it causing evaporation, which cools our body. Many mammals have far fewer sweat glands than us. That's why, in order to stay cool, dogs pant (though dogs and cats have sweat glands in their feet), pigs wallow in water (their sweat glands are in the nose), elephants fan their huge, vascular ears, bears are more active at night, and rats burrow or seek shade during the heat of the day.
Unfortunately, since the late 1950's when deodorant advertisements became common, most of us have come to associate human sweat with something far more sinister -- body odor. The following mini quiz will help you learn more about sweat and how to control body odor.
