EXTREME HEAT PREPAREDNESS

Nebraska summers can bring high temperatures and humidity that are not only uncomfortable, but dangerous. Extreme heat can cause serious illness, especially during prolonged periods of hot weather.

Know the Heat-Related Terms

Heat Wave:
- A prolonged period of unusually hot weather, often accompanied by high humidity.
Heat Index:
- A measure of how hot it feels when humidity is combined with the air temperature. Full sunshine can increase the heat index by as much as 15°F.
Heat Cramps:
- Muscle pains or spasms caused by heavy exertion and excessive sweating. They can be an early warning that your body is struggling with the heat.
Heat Exhaustion:
- A serious condition caused by excessive sweating and fluid loss. Symptoms may include heavy sweating, weakness, dizziness, nausea, headache, and cool or clammy skin.
Heat Stroke:
- A life-threatening emergency in which the body can no longer regulate its temperature. Signs include confusion, loss of consciousness, seizures, and very high body temperature. Call 911 immediately and begin cooling the person.

Prepare for Extreme Heat

  • Make sure air conditioners are working properly and filters are clean.
  • Seal gaps around windows and doors to keep cool air inside.
  • Use shades, curtains, awnings, or window reflectors to block direct sunlight.
  • Have fans available to circulate air.
  • Weather-strip doors and sills to keep cool air in.
  • Identify nearby cooling centers and other air-conditioned public spaces.

Stay Safe During Extreme Heat

  • Stay indoors and out of direct sunlight as much as possible.
  • Spend the hottest part of the day in an air-conditioned location if your home is too warm.
  • Drink plenty of water and don't wait until you are thirsty.
  • Wear loose-fitting, lightweight, light-colored clothing and use sunscreen.
  • Avoid strenuous activity during the hottest part of the day. If you must work outside, take frequent breaks and use the buddy system.
  • Take cool showers or baths and sleep in the coolest part of your home.
  • Limit alcohol, which can contribute to dehydration.
  • Check on family, friends, and neighbors who may be especially vulnerable to extreme heat.
  • Never leave children, vulnerable adults, or pets alone in a parked vehicle.

Find a Cooling Center

If you need relief from the heat, visit an air-conditioned public facility such as a library, community center, shopping mall, or cooling center. Call 211 to find a nearby cooling center or other heat-relief resources.
