The human body makes use of evaporative cooling by perspiration to give off energy even when surrounded by a temperature higher than body temperature.
What happens to the body in hot weather?
The hotter and more humid it gets the more the body has to sweat, increasing the risk of dehydration. In extreme heat the body starts to struggle to cool itself down, which can then lead to heat cramps, heat exhaustion or even heatstroke – also known as sunstroke.
What happens to the body when the temperature gets to 50c?
