why do we smell when we sweat

Sweat itself does not in fact smell. The familiar smell of body odour, or B. O, comes from normal skin bacteria breaking down the sweat secretions released from the sweat glands. Body odour mainly originates from the apocrine glands [link to section] in the armpits, which release a thick, oily sweat rich in proteins and lipids which bacteria on the skin feed on. Body odour occurs during exercise and when we feel strong emotions, because these are the triggers for the apocrine gland to secrete sweat.
