Heat exhaustion is a heat-related illness that can occur after exposure to high temperatures, and it often is accompanied by dehydration. The first signs of heat exhaustion may start suddenly or progress over time, especially with prolonged periods of exercise. Possible symptoms include:
- Cool, moist skin with goosebumps when in the heat
- Heavy sweating
- Faintness
- Dizziness
- Fatigue
- Weak, rapid pulse
- Low blood pressure upon standing
- Muscle cramps
- Nausea
- Headache
If you think you have heat exhaustion, it is essential to immediately get out of the heat and rest, preferably in an air-conditioned room. If you cant get inside, try to find the nearest cool and shady place. Other recommended strategies include:
- Drink plenty of fluids, especially sports drinks to replace lost salt (avoid caffeine and alcohol)
- Remove any tight or unnecessary clothing
- Take a cool shower, bath, or sponge bath
It is important to seek medical attention if your symptoms get worse or they dont improve within one hour. If youre with someone who has heat exhaustion, seek immediate medical help if they become confused or distressed, lose consciousness, or are unable to drink. If their core body temperature reaches 104 F (40 C) or higher, they need immediate cooling and urgent medical attention.
