Body odor is the smell produced by bacteria breaking down sweat on the skin. Everyone has a natural scent, but factors like diet, hygiene, and health can influence how strong that odor is. Common areas where body odor occurs include the armpits and feet, where sweat glands are more concentrated. Maintaining good hygiene, such as regular bathing and using deodorants, can help manage body odor. Certain foods, like garlic and onions, can also affect how a person smells. In some cases, medical conditions may lead to unusual body odors, which may require consultation with a healthcare professional.
