What is sweating?

Everybody sweats.

Sweat, also known as perspiration, is a normal and healthy bodily function and it starts to occur just a few months after birth.

Why people sweat?

We mainly sweat to cool our bodies down, a process called thermoregulation. Our brain sends a signal to over 3 million glands in our body to release sweat (a clear fluid made of water, salts and proteins). As this fluid evaporates from our skin, it lowers our body temperature.

There are many factors that can cause us to perspire:

  • Hot environments
  • General movement and physical activities
  • Emotional feelings, including stress
  • 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
