What causes sweat?
It’s helpful to think of sweat as your body’s natural air conditioning system. When you’re in a warm environment, your body cools you down by producing sweat.
Being active or working out turns up your body’s temperature. Sweating is your body’s way of getting rid of the extra heat.
Emotions such as stress can trigger sweating as well. Feeling embarrassed, anxious or even angry can trigger a release of the hormone adrenaline which leads to sweating.
There are many other factors that can also cause us to perspire:
- Eating hot or spicy food
- Side effects from medication or surgery
- Illness, as our bodies fight infections or fevers
- Hormonal changes such as menopause, pregnancy, menstruation or puberty
Why does sweat smell?
The familiar smell associated with sweat doesn’t come from sweat itself. Body odour is actually a result of sweat reacting with the natural bacteria on your skin.
When your body sweats, it releases fluid from two sets of glands – eccrine and apocrine.
Eccrine glands are found all over the skin and secrete a simple sterile fluid to the surface whenever the temperature rises.
Most apocrine glands in your body are located in the underarms and groin. They first start to function around the time you hit puberty.
When the body sweats, these apocrine glands release a combination of fats, lipids and proteins. The natural bacteria on your skin feed on this mixture, which causes them to thrive and create smelly odours.
