What causes body odor? – Mel Rosenberg

Body odor is what you smell when your sweat comes in contact with the bacteria on your skin. Sweat itself doesn’t smell, but when the bacteria on your skin mix with your sweat, it causes an odor. Body odor can smell sweet, sour, tangy or like onions. The amount you sweat doesn’t necessarily impact your body odor. That’s why a person can have an unpleasant body odor but not be sweatyEccrine glands secrete sweat directly to the surface of your skin. As the sweat evaporates, it helps cool your skin and regulate your body temperature. It doesn’t produce a smell.Sweating is a natural body process, but due to certain foods we eat, hygiene practices or genetics, sweat can have a bad smell once it comes into contact with your skin. Changes in the amount you sweat or the smell of your body odor could indicate a medical condition.Some people are more susceptible to foul body odor than other people.

Stress or anxiety.

Genetics.Several medical conditions and diseases are associated with changes in a person’s usual body scent:
