Treating Heat Exhaustion

Heat exhaustion is dangerous and can lead to death.
Heat exhaustion symptoms include rapid pulse, nausea, fatigue, and lightheadedness.
Heat exhaustion usually happens in hot, humid environments when the body is dehydrated and can't cool itself properly.
There are simple ways to prevent this.
Stay hydrated.
Try to avoid exercising, or otherwise exerting yourself, during the hottest parts of the day.
