Did you know that there’s a way to tell if you’re too dehydrated? You'll know you're too dehydrated if you start to feel dizzy, or notice your body's temperature going up fast. If that happens, lie down immediately and start downing liquids. Even moderate heat can cause mild dehydration. The fix: Drink a full glass of water in the morning to replenish the fluid you lose overnight. Then, sip eight glasses during the day, even if you don’t feel thirsty- especially in these hot, hazy days of Summer!
