What Is Extreme Heat?

Extreme heat is defined as when there are 2–3 days in a row of intense heat and humidity with temperatures 90 degrees or above. This includes days when the temperature “feels like” it is that hot, based on the air temperature and relative humidity.

Extreme heat is the number one weather-related cause of death in the United States. There has been a steady increase in heat-related fatalities over the last few years. 2023 had the highest number of heat related fatalities ever recorded. Take action now to prepare!

During Extreme Heat
Take Action
Stay Cool

If possible, stay out of the sun and stay in air-conditioning.

 

Slow down on strenuous activity and exercise, especially during the sun's peak hours: 11 a.m. to 4 p.m.

 

When outdoors, wear loose-fitting, lightweight, light-colored clothing that cover as much skin as possible. Lightweight, light-colored clothing reflects the heat and sunlight and helps maintain normal body temperature.

 

Never leave children or pets alone in a closed vehicle. Even with the windows cracked open, interior temperatures can rise almost 20°F within 10 minutes. Limit outdoor exposure time for both children and pets.

 

Stay Hydrated

Drink plenty of fluids - preferably water.

 

When working in the heat you should drink one cup (8 ounces) of water every 15 – 20 minutes. That translates to at least 24-32 ounces of water per hour during extreme heat, even if you do not feel thirsty. Drinking water at shorter intervals is more effective than drinking large amounts infrequently.

 

Your body needs water to keep cool. Avoid beverages containing alcohol or caffeine.

 

Avoid using salt tablets unless directed to do so by a physician. Salt causes the body to retain fluids, resulting in swelling and affects areas of your body that help you sweat. Persons on salt-restrictive diets should check with a physician before increasing salt intake.

People who live alone are at a greater risk for heat illness and death. If you have any family, friends or neighbors who may live alone, connect with them, and invite them to join you in your plan to stay cool.
