Definition. Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C).
The medical term is bromhidrosis. Occasional abnormal body odor may be a temporary effect of a metabolic change, such as fruity breath in diabetic ketoacidosis, but by far the most common cause of abnormal body odor is excessive perspiration or hyperhidrosis (overactive sweat glands).
Isovaleric acid is the one associated with a cheesy or sour smell. As a matter of fact, the sweat-bacteria combo ranks the first among the causes of body odor. Adopting proper hygiene measures can help with the problem. An antibacterial soap also often helps and so does deodorants and antiperspirant.
