Heat is the number one weather-related killer, and as carbon pollution continues destroying earth’s atmosphere, global temperatures will keep climbing, bringing us hotter summers and more dangerous heat.

The ability to sweat is one of the primary mechanisms your body uses to cools you down.

When humidity levels rise, sweat does not evaporate as efficiently, which keeps your body from releasing heat as fast as it may need, and this leads to overheating.

Always drink plenty of fluids when you are sweating. Excessive sweating can accelerate dehydration and worsen the situation in high heat environments.
