Exposure to high temperatures, particularly when combined with high humidity, can lead to heat exhaustion or heatstroke.

Take these steps to prevent heat-related illnesses during hot weather:

  • Prevent a sunburn. Protect yourself outdoors with a wide-brimmed hat and sunglasses and use a broad-spectrum sunscreen with an SPF of at least 15.
  • Drink plenty of fluids. Staying hydrated will help your body sweat and maintain a normal body temperature.
  • Never leave anyone in a parked car. This is a common cause of heat-related deaths in children. When parked in the sun, the temperature in your car can rise 20 degrees F (more than 11 C) in 10 minutes.
  • Take it easy during the hottest parts of the day. If you can't avoid strenuous activity in hot weather, drink fluids and rest frequently in a cool spot. Try to schedule exercise or physical labor for cooler parts of the day, such as early morning or evening.
  • Get acclimated. Limit time spent working or exercising in heat until you're conditioned to it. People who are not used to hot weather are especially susceptible to heat-related illness. It can take several weeks for your body to adjust to hot weather.
  • Wear loose fitting, lightweight clothing.
