What Causes Bad Body Odor, and How Do I Get Rid of It?

Stress

If it's not because of something you ate, your funk may have to do with relationship drama or an overloaded work schedule. "One of the number one reasons that body odor can increase, become a little bit more pungent, or have a more lingering scent, is stress," says Sonpal.Your body has two types of sweat glands, according to the Mayo Clinic: eccrine and apocrine. Eccrine glands are everywhere, producing the watery sweat that builds up when you're working out. Apocrine glands, however, are concentrated in your armpits and groin and produce a different kind of fatty sweat. When your anxiety kicks up and the apocrine glands switch on, "that milieu of sweat from the gland in the armpit and the normal surface body bacteria make a smell," Sonpal explains.
