What are the Warning Signs of Heat Exhaustion

(CNN) It seems counter intuitive, but the temperatures overnight may actually be just as dangerous, or even more dangerous than when temperatures are highest during the day. Studies show that when temperatures don't cool off at night, and especially when they remain above 80 degrees, your body, which should be in recovery mode, can't recover. The results of not being able to fully cool down can be deadly.

Another surprising fact is that most heat-related deaths don't occur in the hottest weather zones. People in those regions are more equipped to deal with the heat, with better infrastructure, building materials, and access to air conditioning.Heat stroke can happen very quickly after heat exhaustion settles in.
  • Drink plenty of water. Avoid drinks with alcohol or caffeine, which will only dehydrate you faster.
  • Eat light meals. Avoid heavy meals that are high in protein, which cause the body to work harder to digest. Eat more carbohydrates so your body doesn't have to use as much energy to digest.
  • Wear light-colored clothing, which will reflect sunlight instead of absorbing it. It could keep your body temperature down several degrees.
  • Studies show the best clothes to wear while exercising are none at all! This is because air needs to flow over your skin in order for sweat to cool you off -- as much of it as possible. But if that's not an option, loose-fitting clothing is your next best bet.
  • Find an air conditioned place to get out of the heat. In temperatures above 80 degrees, fans won't do you any good -- they just blow more hot air around.
