If you're experiencing symptoms of mild dehydration or heat injury, or you're just plain sweating a lot, make sure you replace your salt. Don't just chug salt straight from the box, however. Try eating pretzels, salted crackers or salty nuts.
And to slough off the dry, flaky skin that comes from dehydration, try this: After you bathe and while your skin is still wet, sprinkle salt onto your hands and rub it all over your skin. This salt massage will remove dry skin and make your skin smoother to the touch. It will also invigorate your skin and get your circulation moving. Also, if your skin is itchy as a result of dehydration, soaking in a tub of salt water can be a great itchy-skin reliever. Just add 1 cup table salt or sea salt to bathwater. This solution will also soften skin and relax you.
