I got heat exhaustion in high school during one game in central valley CA. I kept drinking water and taking deep breaths, but nothing cooled me down nor could I catch my breath. The refs had to stop the game, the other team brought me to their sideline and started shoving bags of ice into my uniform, then they had me go soak in their school's pool for a few minutes to cool me down.

I've tried to avoid excessive heat ever since. I carry a water bottle with me wherever I go and it's full anytime I leave the house.

I actually quit football my junior year because we moved across the country to a much warmer and more humid place, and I was not about to deal with that bullshit again.
