Staying safe in the heat and humidity
Summer heat and humidity can be dangerous , especially for those with underlying health conditions or who work or exercise outdoors.
It’s important to be prepared and stay healthy for hot days as climate change brings more frequent extreme weather.
Stay informed about weather conditions
If you are working, playing, or exercising outdoors, it is important to understand how hot and humid days will impact you.
- Stay informed about heat alerts, which are issued by the National Weather Service (NWS) and publicized by local media.
- If you are planning to be active outdoors, check your local weather forecast. Use the National Weather Service HeatRisk page to help the current and forecasted heat risk where you live.
Stay safe in hot weather
Take the following steps to keep yourself cool and safe when temperatures rise:
Cold-water cooling
You can use cold water or ice to stay cool in various ways, including:
- Showering or bathing
- Place damp or frozen towels on your body
- Spraying yourself
- Immerse your feet
Dress for heat
- Wear light, loose-fitting clothing
- Light-colored clothes will reflect light and keep you cooler
Eat for heat
- Drink plenty of water to help your body cool itself
- Eat water-rich foods like vegetables, fruits, and drinks with lots of water
- Avoid diuretics like coffee and tea so your body can retain more water
- Eat smaller, but more frequent meals to reduce stress on your body
- Avoid heavy, fried foods or big meals

Talk to your healthcare provider or pharmacist about your medications and how you can protect yourself in hot weather.
Cool your home
Keep your home safe and comfortable when temperatures rise.
Fan and air conditioning
- Use fans to safely move cool air around your home up to 95 degrees indoors
- Maintain air conditioning filters to maximize efficiency and improve air quality
- Set your air conditioning or thermostat to 72 to 78 degrees to keep your home safe and cool while decreasing your energy bill
Ventilate
- Allow cool air to enter the home at night and close windows when it’s hot
- Blow air out a window to allow cooler air to move into the room
- Weatherize your home to block hot air drafts
Block sunlight
- Cover sunny windows
- Open shades at night to radiate heat outside
- Install or extend outdoor awnings to create shade
- Limit use of lights, cooking equipment, and computers
- Consider cooking early in the day or in the evening
Safety with no power
- Store refrigerated medications in a tightly sealed, waterproof bag in a cooler
- Check on your neighbors, especially the elderly and young
- If you are on life saving devices that require electricity, check with your utilities ahead of time to have your power prioritized
Find a place to stay cool
If you can’t cool yourself, go to a library, community center, or shaded park. Malls or indoor retail centers can be a good spot to be active and cool.
