Quick Cool Down

First, put down the towel. Research shows that resisting the urge to mop your brow can actually help you cool down quicker. Standing in front of a fan or using your blow dryer’s cool setting helps sweat evaporate naturally and pulls heat away from your body, says kinesiologist Dr. Ed Coyle from the University of Texas at Austin. You can also put an ice pack on the back of your neck, where your blood flows close to the surface of your skin, suggests Dr. Lewis Maharam, who often treats overheated runners as medical director for the ING New York Marathon. As the blood circulates through your body, you chill out. Running cool water on the insides of your wrists has a similar effect.
