Heat exhaustion is a heat-related illness that can occur after you've been exposed to high temperatures, and it often is accompanied by dehydration.
Causes[edit]
There are two types of heat exhaustion:
- Water depletion. Signs include excessive thirst, weakness, headache, and loss of consciousness.
- Salt depletion. Signs include nausea and vomiting, muscle cramps, and dizziness.
Although heat exhaustion isn't as serious as heat stroke, it isn't something to be taken lightly. Without proper intervention, heat exhaustion can progress to heat stroke, which can damage the brain and other vital organs, and even cause death.
Symptoms of Heat Exhaustion[edit]
The most common symptoms of heat exhaustion include:
- Confusion
- Dark-colored urine (a sign of dehydration)
- Dizziness
- Fainting
- Fatigue
- Headache
- Muscle or abdominal cramps
- Nausea, vomiting, or diarrhea
- Pale skin
- Profuse sweating
- Rapid heartbeat
Treatment[edit]
If you, or anyone else, has symptoms of heat exhaustion, it's essential to immediately get out of the heat and rest, preferably in an air-conditioned room. If you can't get inside, try to find the nearest cool and shady place.
Other recommended strategies include:
- Drink plenty of fluid (avoid caffeine and alcohol).
- Remove any tight or unnecessary clothing.
- Take a cool shower, bath, or sponge bath.
- Apply other cooling measures such as fans or ice towels.
If such measures fail to provide relief within 15 minutes, seek emergency medical help, because untreated heat exhaustion can progress to heat stroke.
Prevention[edit]
Prevention is the best way to deal with heat exhaustion. Some preventive measures include:
- Drink plenty of fluids.
- Wear loose, lightweight clothing and a hat.
- Apply sunscreen of SPF 30 or higher.
- Take it easy during the hottest parts of the day.
- Be a good role model.
