This summer tip could literally save your life. When the heat hits hard, your body works overtime and most people don’t realize how quickly things can go wrong. Stopped sweating and feeling dizzy? That’s not just discomfort. That could be heat stroke, and it can cause brain damage if you don’t act fast. The fix? Hydration – but done right. Here’s what you need to know:

• Drink 1 quart of water per hour when working or exercising in the heat
• Break it down to 1 cup every 15 minutes – steady, not all at once
• Don’t forget salt – chugging water without it can still land you in the hospital
• Skip meals and you’re putting yourself at even more risk

And when you finally get out of the heat? Keep drinking. Your body needs time to gradually replace everything it sweated out. Stay smart, stay cool.
