When outdoors

  • Wear a sunscreen with a minimum SPF 15. Apply at least 30 minutes prior to going outdoors, and reapply as necessary.
  • Rest frequently in shady areas so that the body's temperature has a chance to recover.
  • If unaccustomed to working or exercising in a hot environment, gradually increase the pace and limit exercise or work time.
  • Wear lightweight, loose-fitting clothing; sunglasses to protect the eyes; and a wide-brimmed hat to provide shade and keep the head cool.
  • Take special precaution with infants and young children by dressing them in loose, cool clothing and shading their heads and faces with hats or an umbrella. Protect their feet with shoes.

To avoid heat-related illness

  • Never leave children or pets inside a parked vehicle, even if the windows are open.
  • HYDRATE. Increase fluid intake, regardless of activity. Don't wait until you’re thirsty to drink.
  • Avoid drinks containing alcohol, caffeine or large amounts of sugar. They dehydrate the body.
  • Avoid exercise or outdoor activity between the hours of 11 a.m. and 3 p.m. when the sun is at its peak intensity.
  • If air conditioning is not available, put shades over windows and use cross-ventilation and fans to cool rooms.
  • Take a cool shower or bath.
  • Some medications may increase the risk of heat-related illness. Consult your physician.
