Drink More Fluids!
Drink more fluids, regardless of how active you are.
Don’t wait until you’re thirsty to drink.
Warning: If your doctor limits the amount you drink or has you on water pills, ask how much you should drink while the weather is hot.
Stay away from very sugary or alcoholic drinks—these actually cause you to lose more body fluid.
Also avoid very cold drinks, because they can cause stomach cramps.
