Heat exhaustion occurs when your body overheats and loses too much water and salt through sweating. It is often caused by prolonged exposure to high temperatures, especially when combined with dehydration or physical activity. If left untreated, heat exhaustion can progress into heat stroke, which is a life-threatening emergency.
If you notice these symptoms in yourself or someone else, it is important to act quickly.
Move to a shaded area, an air-conditioned building, or even a parked car with the air conditioning running. Reducing exposure to direct heat is the first and most important step.
Drink cool water slowly. Sports drinks can help replace lost electrolytes, but avoid alcohol or caffeine, which can worsen dehydration.
Use cool, damp cloths on your neck, wrists, and forehead. If possible, take a cool shower or sit in front of a fan. Removing excess clothing can also help your body cool down more efficiently.
Lie down and elevate your legs slightly. Give your body time to recover before returning to any activity.
If symptoms last longer than an hour, worsen, or include confusion, fainting, or a very high body temperature, seek medical attention immediately. These may be signs of heat stroke, which requires emergency care.
Drink water consistently throughout the day, not just when you feel thirsty. In extreme heat, your body loses fluids quickly.
Schedule outdoor activities early in the morning or later in the evening when temperatures are lower. Avoid peak heat hours, typically between late morning and early evening.
Wear lightweight, loose-fitting, and light-colored clothing. Hats and sunglasses can provide additional protection from the sun.
If you are working or exercising outdoors, take frequent breaks in shaded or air-conditioned areas.
Sunburn reduces your body’s ability to cool itself, increasing your risk of heat-related illness.
