Extreme Heat Safety

Climate change is making extreme heat more frequent, severe and longer-lasting. Extreme heat describes temperatures that are much hotter than average.ā€‹ Summer heat waves can be dangerous, especially for young children, older adults, people with chronic diseases and disabilities, outdoor workers, people who are unhoused and those who are pregnant. Itā€™s important to protect yourself and your loved ones by checking in on friends and family who may need assistance, monitoring weather forecasts, staying hydrated, limiting time in the heat and staying in or visiting cool spaces.

Follow these tips foā€‹r staying cool during extreme heat:

Stay Cool (Especially During the Hottest Times of the Day):

  • Those without air conditioning should visit a local cooling center or public locations such as a library or shopping mall.
  • Avoid physical exertion or exercising outdoors.
  • Wear lightweight, light colored, loose clothing, hats, sunglasses and sunscreen.

Stay Hydrated:

  • Drink plenty of fluids, especially water, even when not thirsty; drink low-sugar sports drinks (alternating with water) to help replace electrolytes lost if engaging in vigorous exercise.
  • Avoid sugary, alcoholic and energy drinks.
  • Eat plenty of fruits and vegetables.

Stay Connected:

  • Check in on those at high risk of heat-related illness.
  • Use a buddy system when working in the heat.

Stay Informed:

  • Check the local news for weather forecasts, extreme heat alerts, and cooling centers.
  • Look up the 7-day ā€œHeatRiskā€ forecast to plan ahead and prepare for heat

Heat-related illnesses are preventable. Use this toolkit to inform your community about heat and summer safety. For more related messaging, visit our Summer & Warm Weather Safety Toolkit, Drowning Prevention Toolkit and Wildfire Safety Toolkit.
