Treatment

Untreated, heat exhaustion can lead to heatstroke, which is a life-threatening condition. If you suspect heat exhaustion, take these steps immediately:

• Move the person out of the heat and into a shady or air-conditioned place.
• Lay the person down and raise the legs and feet slightly.
• Remove tight or heavy clothing.
• Have the person sip chilled water, a sports drink containing electrolytes or another nonalcoholic beverage without caffeine.
• Cool the person by spraying or sponging with cool water and fanning.
• Monitor the person carefully.

Contact a healthcare professional if symptoms get worse or if the person doesn't improve after taking first-aid measures.
