Myth Busters #47

Im dripping with sweat! Somebody get me a towel!

Do not wipe off your sweat! Sweating is like your body’s own air conditioning system, used to cool itself down. When you exercise your body temperature rises and you begin to sweat to try and bring your body temperature back down to a normal level. This is done through a process of evaporation where the heat from your skin will cause the sweat to evaporate, which results in heat loss. If you were to wipe the sweat off your body it will take longer for you to cool yourself down and will also result in a extra fluid loss. So no matter how yucky it feels try to avoid wiping off your sweat.
