The best tips to protect yourself from heat-related illnesses are:

  • Stay hydrated by limiting caffeine and drinking at least half of your body weight in ounces.
  • Limit time outdoors after 9 a.m. and before sunset.
  • Take lots of breaks in the AC if you do have to be outside.
  • Wear lightweight and loose-fitting clothing when outdoors.
