Heat exhaustion is a serious condition that affects millions of people each year. It happens when your body gets too hot and can’t cool down properly. I have seen many people end up in the hospital because they didn’t know how to prevent this dangerous condition. The good news is that heat exhaustion can be prevented with the right steps. This guide will teach you simple ways to stay safe when temperatures rise.
What is Heat Exhaustion?
It is your body’s way of telling you it’s overheating. When temperatures climb high, your body works hard to stay cool through sweating. But sometimes, this system fails.
Picture heat exhaustion as your body running hot like an overworked motor. When a car overheats, it stops working properly. The same thing happens to your body during heat exhaustion. Your body temperature rises, and you lose important fluids and salts through heavy sweating.
Heat exhaustion differs from heatstroke vs heat exhaustion. Heat stroke is more dangerous and life-threatening. But heat exhaustion can quickly turn into heat stroke if you don’t treat it fast.
