Heat Exhaustion

Symptoms of Heat Exhaustion

  • Headache, dizziness, or fainting
  • Weakness and wet skin
  • Irritability or confusion
  • Thirst, nausea, or vomiting

What Should I Do If I Think I Have Heat Exhaustion?

If you think you have heat exhaustion, get out of the heat quickly. Rest in a building that has air-conditioning. If you can't get inside, find a cool, shady place. Drink plenty of water or other fluids. Do NOT drink alcohol or caffeinated drinks (such as soda). These can make heat exhaustion worse. Take a cool shower or bath, or apply cool water to your skin. Take off any tight or unnecessary clothing.

If you do not feel better within 30 minutes, you should contact your doctor. If heat exhaustion is not treated, it can progress to heatstroke.

Symptoms of Heat Stroke

  • High fever (104°F or higher)
  • Heat StrokeSevere headache
  • Dizziness and feeling light-headed
  • A flushed or red appearance to the skin
  • Lack of sweating
  • Muscle weakness or cramps
  • Nausea
  • Vomiting
  • Fast heartbeat
  • Fast breathing
  • Feeling confused, anxious or disoriented
  • Seizures

Heatstroke is when the internal temperature of the body reaches 104°F. It can happen when your body gets too hot during strenuous exercise or when exposed to very hot temperatures, or it can happen after heat exhaustion isn't properly treated. Heatstroke is much more serious than heat exhaustion. Heatstroke can cause damage to your organs and brain. In extreme cases, it can kill you.

What Should I Do If I Think Someone Has Heatstroke?

If you think someone might have heatstroke, call emergency medical personnel immediately. While you are waiting for medical assistance, take the person into an air-conditioned building or a cool, shady place. Remove the person's unnecessary clothing to help cool him or her down. Try to fan air over the person while wetting the skin with water. You can also apply ice packs to the person's armpits, groin, neck and back. These areas contain a lot of blood vessels close the surface of the skin. Cooling them with ice packs can help the person cool down.
