Why does sweat smell?
Sweat cools us down and lubricates those parts of the body that rub against each other, such as the crotch or the armpits. Actually, the body produces two different kinds of sweat, eccrine and apocrine. Neither type of sweat has an odour, but apocrine reacts with the bacteria on our skin. As the bacteria break down the apocrine, the musty, stale smell we know as BO occurs.
Everyone has their own body odour, as unique as a thumbprint. The Australian Civil Service has actually explored using body odour as a security method to restrict access to classified information on computers! However, though body odour may be a necessary and individual trait, when it becomes offensive to others it can be very embarrassing.
Some peoples apocrine glands are bigger and more active than others. Similarly, some of us have more tenacious skin bacteria. Some people may find that they sweat much more than normal, a condition known as hyperhydrosis. Certain unusual-smelling body odours are symptoms of more serious complaints.
Occasionally, people believe that they smell bad when in fact they do not. More often, though, it is the opposite case. We arent as aware of our own smell as others are because we live with our personal odour all the time. If you suspect you have a body odour problem, it can usually be resolved by regular bathing, using deodorant and washing your clothes.
To make sure:
Sometimes a bad smell can in fact be a symptom of something worse. If you notice any of the following body odours, or any consistent odour that is not your normal personal smell, you may need to consult your GP for tests:
