Body Odor, often abbreviated as B.O., or bromhidrosis (also called bromidrosis, osmidrosis and ozochrotia) is the smell of bacteria growing on the body. These bacteria multiply rapidly in the presence of sweat, but sweat itself is almost completely odorless. Body odor is associated with the hair, feet, groin (upper medial thigh), anus, skin in general, armpits, genitals, pubic hair, and mouth.
Body odor is largely influenced by major histocompatibility complex (MHC) molecules. These are genetically determined and play an important role in immunity of the organism. The vomeronasal organ contains cells sensitive to MHC molecules in a genotype-specific way. Experiments on animals and volunteers have shown that potential sexual partners tend to be perceived more attractive if their MHC composition is substantially different. This behavior pattern promotes variability of the immune system of individuals in the population, thus making the population more robust against new diseases.
Body odor affects millions of people, some are not bothered by it at all. Others however suffer greatly and are constantly seeking body odor remedies. The psychological impact on people who have excess body odor, or foul body odor can be devastating. These people are constantly embarrassed and are unable to eliminate body odor by taking a bath or shower. They suffer because of various reasons. Fishy body odor for example affects people who are unable to digest certain foods. This condition is especially noticeable during menstruation. Trimethylamine is the main cause of the fishy smell and can be avoid if a person ate a proper body odor diet.
- After washing with soap and completely drying, immediately apply an underarm antiperspirant. Remember, deodorants do not prevent sweating. They mainly mask the smell of the bacteria on your sweaty skin. Antiperspirants are chemical agents that reduce sweating. Many antiperspirant preparations also contain a deodorant, which helps to mask the smell. Check the product you use to make sure it contains an antiperspirant.
- Keep your underarms dry. Bacteria have a hard time breeding in dry areas of the body.
- Try a solution of hydrogen peroxide and water to fight body odor. Use one teaspoon of peroxide (3%) to one cup (8 ounces) of water. Wipe this on affected areas (underarm, feet, groin) with a washcloth. This may help destroy some of the bacteria that creates odor.
- If sweat from working out is your No. 1 cause of body odor, wash your workout clothes often. Sweaty gym clothes are a bacteria-breeding ground.
- Change your diet. Sometimes, fatty foods, oils, or strong-smelling foods like garlic, curry, and onions, can seep through your pores and cause body odor. (Always see a doctor or dietician before making drastic dietary changes.)
- If you have excessive sweating (called hyperhidrosis), talk to your doctor. There are many treatment options for those with more severe sweating who desire more permanent treatments. Also, certain medical problems can lead to excessive sweating. Your doctor can make a diagnosis and prescribe treatment.
- Shaving your underarm regularly will help prevent the accumulation of bacteria and can reduce sweat and odor.
