Humans aren’t put together to withstand high temperatures for long amounts of time. Sure, the body has some survival mechanisms, but even in those with health and youth on their side, they’re not foolproof.

Humans aren’t made to withstand high temperatures for long durations. Sure, the body has some survival mechanisms, but even in those with health and youth on their side, they’re not foolproof.

The first thing an overheated body wants to do is cool itself down. In less extreme conditions the heat inside the body will simply move towards the skin and then escape into the air.

More serious circumstances lead to sweating. This occurs when the temperature outside of the body is over 100 degrees Fahrenheit, and the body starts to absorb the heat.

When this occurs the sweat heats up and rises to the skins surface. If the atmosphere is dry, it just evaporates into the air.

Humidity aggravates the process, making it harder for the body to release the heat energy.

Humid or dry, it’s vital that the liquids lost are replaced. Once the temps get up to heatwave levels, a person can lose up to a quart and a half of water an hour.

Symptoms that your body’s had enough heat include weakness and nausea. If delirium and fainting occur, it’s best to seek medical attention.
