Extreme Heat

Heat kills by pushing the human body beyond its limits. In extreme heat and high humidity (which is when the air has moisture and feels sticky) the body must work extra hard to maintain a normal temperature and keep the body comfortable. A heat wave is an extended period of extreme heat, and there is often high humidity. These conditions can be dangerous for people who don’t take care of themselves properly.






Know what to do before, during and after extreme heat

  • Create a communications plan with your family before extreme heat hits.
  • Have emergency supplies in place at home, at work, and in the car.
  • Listen to local officials.





Creating your Family Emergency Communication Plan starts with one simple question: “What if?”

“What if something happens and I’m not with my family?” “Will I be able to reach them?” “How will I know they are safe?” “How can I let them know I’m OK?” During a disaster, you will need to send and receive information from your family.

Communication networks, such as mobile phones and computers, could be unreliable during disasters, and electricity could be disrupted.

Planning starts with three easy steps


Here are some tips on staying cool and safe during extreme heat:

Be familiar with your local weather forecast by visiting or on your phone

  • Cover windows that receive morning or afternoon sun with drapes, shades, awnings, or louvers. (Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent.)
  • Eat well-balanced, light, and regular meals. Avoid using salt tablets unless directed to do so by a physician.
  • Drink plenty of water and limit intake of alcoholic beverages. Persons who have epilepsy or heart, kidney, or liver disease; are on fluid-restricted diets; or have a problem with fluid retention should consult a doctor before increasing liquid intake.
  • Check on family, friends, and neighbors who do not have air conditioning and who spend much of their time alone. Never leave children or pets alone in closed vehicles.
  • Avoid strenuous work during the warmest part of the day. Use a buddy system when working in extreme heat, and take frequent breaks.
  • And hotter weather also affects pets, so remember to give them plenty of water and keep them inside. Check out for more tips on getting prepared, for any emergency.
