Heat-Related Illnesses

 

*2010 Local Cooling Center Contact Information by jurisdiction:

Local cooling centers are activated where applicable, when weather conditions require.

 

Usually your body can cool itself by letting heat escape through the skin. However, when that fails, a person can become ill.

Who is susceptible to Heat-Related Illnesses?

Anyone can be a victim of a heat-related illness, such as people working or exercising under the sun. However, those most at risk are:

  • Children under five
  • People over age 65
  • People with chronic illnesses and disabilities
  • People taking certain medications

How to Prevent Heat-Related Illness

  • Dress for the heat. Wear lightweight, light-colored and loose clothing. Light colors reflect away some of the sun’s heat. Wear a hat or use an umbrella.
  • Drink plenty of water. Carry water or juice with you and drink even if you don’t feel thirsty. Avoid alcohol or caffeine, which dry out the body.
    Eat smaller meals and eat more often. Avoid foods that are high in protein which increases your metabolic heat.
  • Slow down. Avoid strenuous activity. Limit activity to the coolest part of the day, usually in the morning between 5am and 8am.
    Stay indoors as much as possible.
  • Take regular breaks when active on a hot day. If you or someone else is showing signs of a heat-related illness, stop the activity and find a cool place to rest.
  • When possible stay in air-conditioned areas. If your home is not air-conditioned, consider a visit to a shopping mall or public library.
  • NEVER leave pets or young children in a car, even with the windows down.
  • Check on elderly relatives or neighbors at least once daily.

Signs and Symptoms of a Heat-Related Illness

  • Heat Cramps. These can happen because of loss of water and salt from heavy sweating. Heat cramps can cause muscle pain and spasms, but are not as serious as heat exhaustion and heat stroke.
  • Heat Exhaustion symptoms include cool, moist, pale or flushed skin; heavy sweating; headache; nausea or vomiting; dizziness; and exhaustion. Body temperature may be near normal.
  • Heat Stroke symptoms may include hot, red skin; fainting or passing out; rapid, weak pulse; and rapid, shallow breathing. Body temperature can be 105 degrees or higher.
  • Both heat exhaustion and heat stroke can become serious and even deadly if not taken care of right away.

First Aid Treatment for Heat-Related Illnesses

Heat Cramps:

Get the person to a cool place and have him or her rest comfortably. Lightly stretch the cramped muscle and give the person a half glass of cool water every 15 minutes. Do not give liquids with alcohol or caffeine in them.

Heat Exhaustion:

Get the person out of the heat and into a cool place. Remove or loosen tight clothing and apply cool, wet cloths. If the person is conscious, give the person a half glass of cool water every 15 minutes. Do not give liquids with alcohol or caffeine in them. Let the victim rest in a comfortable position and watch carefully for changes in his or her condition. If there is no visible change in condition, or if the person is unconscious, call 911.

Heat Stroke

Heat Stroke is a life threatening situation, and help is needed fast. If you suspect a person is suffering from heat stroke, call 911, and move the person to a cool place. Quickly cool the person by putting them in a cool bath or by wrapping wet sheets around their body and fanning them. Keep the person lying down. If the person is unconscious, refuses water, or is vomiting, do not give anything to drink.
