Why is body odor usually confined to the armpit, even when a lot of people take extra measures to protect against it?
The human body has two types of sweat glands: eccrine and apocrine. Eccrine glands are present all over, and typically secrete sweat that is mostly made of water. Their purpose is to keep your body cool when you're exposed to heat or enduring intense exercise.
The Short Answer
The human body has two types of sweat glands: eccrine and apocrine. Eccrine glands are present all over, and typically secrete sweat that is mostly made of water. Their purpose is to keep your body cool when you're exposed to heat or enduring intense exercise. Apocrine glands, however, are located in targeted areas of the body—the armpits, for example—and they don’t really do much to cool you down. Instead they release proteins and lipids, and those molecules are the real smell culprits. Bacteria that live on the outside of your armpits feed on the secreted lipids, allowing them to thrive. They also disrupt the outer shell of the proteins that are secreted, releasing odor.
