AT SOME point in our lives, all of us have experienced being next to a person with body odour. It’s never a pleasant experience to sit next to a smelly classmate or be crammed on a train full of sweaty people.

More importantly, people with body odour may suffer from personal and social relationships. Feelings of embarrassment and decreased self-confidence are common.

SWEATING IT OUT
Sweating is the body’s biological way of regulating temperature, that’s why sweating is more profuse when it’s hot. Composed mainly of salt and water, sweat produces a cooling effect on the body as it evaporates from the skin.

Although about two to four million sweat glands are distributed on the skin, some body parts are more likely to sweat because they have more sweat glands.

According to Dr Chan Yuin Chew, a dermatologist at Gleneagles Medical Centre, “The palms, soles and underarms contain a lot of sweat glands.”

Sweat glands occurring over most parts of the body are called eccrine glands and they are responsible for producing the watery component of sweat.

Those found in hairy areas such as the scalp, armpits and groin are called apocrine glands. Bacterial breakdown of sweat produced from these glands is most likely to produce body odour because it contains protein, carbohydrate, ammonia and fats.

As these glands only mature during puberty, young children rarely develop body odour.

Several factors influence the way people sweat. Certain foods (spicy) and beverages (hot and those with alcohol or caffeine) can make you sweat.

Other factors that increase sweating include certain medical conditions (fever, hyperthyroidism, heart attack, tubeculosis, malaria) and medicines (morphine, anti-depressants).

“When one is excited or angry, there is increased sympathetic activity and one will notice that he or she will start sweating more profusely,” says Dr Eileen Tan, a dermatologist at the Eileen Tan Skin, Laser and Hair Transplant Clinic in Mount Elizabeth Medical Centre.

DECODING BODY ODOUR
Body odour is an unpleasant smell produced by a sweating and unhygienic person. Most of us would point to sweating or perspiration as the culprit, but it is not.

Sweat is actually odourless.

Dr Tan says, “Body odour is caused by a natural process involving sweat that occurs on the skin’s surface. However, if sweat is left on the skin for a long period of time, the bacteria that normally live there feed on it and break it down. This process releases chemicals that cause the unpleasant smell.”
