Sweating is a controlled process that cools the skin and helps regulate body temperature. Sweat glands are located all over the body, particularly on areas of high heat production such as the palms and soles of hands, back of neck, forehead and underarms. The sweat produced from these glands contains water which evaporates through tiny microscopic pores in our skin to cool it down. In very hot environments however this mechanism may not be enough to keep us comfortable so we sweat too!
How does sweating help protect against overheating?
In addition to cooling our bodies down when needed, sweating also protects us from overheating by removing excess moisture from our skins surface. This allows it to become cooler for longer before becoming saturated with fluid again.
