Everyone needs to know how to recognize the symptoms of heat illness. Knowing how to treat heat exhaustion and heat stroke could save your life or the life of someone else.

The key to avoid heat illness—pay attention to how you feel and take necessary preventative measures:

• Hydration—Stay well hydrated, and possibly aim toward overhydration if you know you’ll be in the heat for a lengthy amount of time.
• Wear proper clothing—Loose fitting and light colors.
• Time your activities—Avoid the hottest parts of the day if possible.
