Sweating is one of the natural ways the human body maintains its normal temperature. The body has two types of sweat glands: Apocrine, which are located in the armpits, face, scalp and parts of the trunk; and Eccrine, which are distributed throughtout the body and give off a quart or more of perspiration a day.
Apocrine sweat is scant, milkly, and made up of water, carbohydrates, proteins and lipids ; these substances have a distinctive odor when they are broken down by the bacteria that live on the skin.
In contrast, Eccrine sweat is mostly water, with varying amounts of salt, potassium, urea and ther substances. It has little or no odor itself, but eccrine sweat can transmit the smells of alchol and certain foods, especially garlic and onions, resulting in an unpleasant body odor.

Areas that are normally encased in clothing — the feet, armpits, and genital and anal areas — are most affected by odor problems because bacteria and yeast organisms proliferate in moist, dark places.
