 having these long duration heat waves like in Phoenix last year when they broke their record of 110 plus degree days and also within that had a broken record of overnight lows not going below 90 degrees. When your body doesn't have a chance to cool down, you haven't done it. So hydrate early, hydrate before, stay in the shade. My understanding is even five degrees cooler can make a difference. Ginger Zee, thank you so much. Thank you.
