Why Do We Sweat?

The video explains why our bodies sweat, focusing on its role in cooling down the body when it overheats due to physical activity or high temperatures. It describes the process where the brain signals sweat glands to produce sweat, which is primarily water but also contains electrolytes and other substances. As sweat evaporates from the skin, it removes excess heat, thus cooling the body. The video concludes with a recap of the reasons behind sweating.
