Body odor, commonly referred to as BO, is the unpleasant smell that can arise from the body, particularly in areas like the armpits and feet. It is primarily caused by the breakdown of sweat by bacteria on the skin. While sweat itself is mostly odorless, the interaction with bacteria can produce various compounds that lead to a noticeable scent. Factors such as diet, hygiene, and genetics can influence the intensity of BO. Regular bathing and the use of deodorants or antiperspirants can help manage body odor. Additionally, certain foods, like garlic and onions, may contribute to stronger body odor due to their chemical composition.
