Drink more fluids (2 – 4 glasses of cool, nonalcoholic fluids each hour), regardless of your activity level. Don’t wait until you’re thirsty to drink; by then you’re already dehydrated.
Don’t drink liquids that contain large amounts of sugar or caffeine– these actually cause you to lose more body fluid.
Take frequent rest breaks in shady areas or in air- conditioned spaces on campus, if available. Air conditioned, indoor spaces provide the best relief from outdoor heat and sun exposure.
Electric fans may provide comfort, but when the temperature reaches the high 90s or above, fans WILL NOT prevent heat-related illness. Splash your face and any exposed skin with cool water or moving to an air-conditioned location to cool off.
Wear lightweight, light-colored, loose-fitting clothing made of natural fibers like cotton. Synthetic fibers like polyester don’t breathe and won’t allow for evaporation of sweat, which cools your body.
Do not sit in a closed vehicle. Studies show that there is an average increase in interior temperature of 40°F in 30 minutes, meaning if it’s 100°F outside, it will be 140°F inside the vehicle, or even hotter, within 30 minutes. And cracking the window made no measurable difference in temperature.
Although anyone can suffer from heat-related illness, some people are at greater risk than others so check regularly on people aged 65 and over; and those who have a physical illness.
Protect yourself from the sun by wearing a hat and sunglasses and wear sunscreen of SPF 15 or higher.
Apply the sunscreen at least 30 minutes BEFORE sun exposure, as sunscreen takes 30 minutes to reach full effectiveness. Reapply after sweating, vigorous activity, or toweling
