Why do we sweat?

Sweating is the biological phenomenon that regulates the temperature of the human body.  When the body’s temperature increases above 36 degrees, the hypothalamus — our brain’s thermostat — signals our body to activate its sweat glands.  Once our body begins to perspire, our sweat evaporates and lowers your body temperature closer to 36 degrees.
We often sweat more while exercising or working out, but plenty of other activities prompt our body’s temperature to rise, including situations that make us feel anxious, embarrassed or even angry at times.

What is the difference between stress sweat and workout sweat?

Stress sweat is caused when our body reacts to an emotion, for instance, anxiety, embarrassment or anger.  Stress sweat is released from the apocrine glands, generally situated near hair follicles under our arms, around the groin and on our scalp. Stress sweat is initially odourless during secretion. However, its slow evaporation as compared to the quick evaporation of workout sweat can lead to the development of strong, unpleasant odours by its combination with bacteria on the skin.
Workout sweat is released due to physical exertion, hot and humid weather conditions or even the excess intake of spicy foods.  This type of sweat is secreted through the eccrine glands, which cover nearly the entire body (but are concentrated near the forehead, palms and feet). These glands produce a clear, watery fluid during exercise or and while we eat spicy food items.
