Lifestyle and home remedies
Home treatment isn't enough for heatstroke. If you have signs or symptoms of heatstroke, seek emergency medical help. Others should take steps to cool you off while waiting for emergency help to arrive. Don't drink any fluids while waiting for medical assistance.
If you notice signs of heat-related illness, lower your body temperature and prevent your condition from progressing to heatstroke. In a lesser heat emergency, such as heat cramps or heat exhaustion, the following steps may lower your body temperature:
- Get to a shady or air-conditioned place. If you don't have air conditioning at home, go someplace with air conditioning, such as the mall, movie theater or public library.
- Cool off with damp sheets and a fan. If you're with someone who's experiencing heat-related symptoms, cool the person by covering him or her with damp sheets or by spraying with cool water. Direct air onto the person with a fan.
- Take a cool shower or bath. If you're outdoors and not near shelter, soaking in a cool pond or stream can help bring your temperature down.
- Rehydrate. Drink plenty of fluids. Also, because you lose salt through sweating, you can replenish salt and water with some sports drinks. If your doctor has restricted your fluid or salt intake, check with him or her to see how much you should drink and whether you should replace salt.
- Don't drink sugary or alcoholic beverages to rehydrate. These drinks may interfere with your body's ability to control your temperature. Also, very cold drinks can cause stomach cramps.
Heatstroke is predictable and preventable. Take these steps to prevent heatstroke during hot weather:
- Wear loosefitting, lightweight clothing. Wearing excess clothing or clothing that fits tightly won't allow your body to cool properly.
- Protect against sunburn. Sunburn affects your body's ability to cool itself, so protect yourself outdoors with a wide-brimmed hat and sunglasses and use a broad-spectrum sunscreen with an SPF of at least 15. Apply sunscreen generously, and reapply every two hours — or more often if you're swimming or sweating.
- Drink plenty of fluids. Staying hydrated will help your body sweat and maintain a normal body temperature.
- Take extra precautions with certain medications. Be on the lookout for heat-related problems if you take medications that can affect your body's ability to stay hydrated and dissipate heat.
Never leave anyone in a parked car. This is a common cause of heat-related deaths in children. When parked in the sun, the temperature in your car can rise 20 degrees F (more than 6.7 C) in 10 minutes.
It's not safe to leave a person in a parked car in warm or hot weather, even if the windows are cracked or the car is in shade. When your car is parked, keep it locked to prevent a child from getting inside.
- Take it easy during the hottest parts of the day. If you can't avoid strenuous activity in hot weather, drink fluids and rest frequently in a cool spot. Try to schedule exercise or physical labor for cooler parts of the day, such as early morning or evening.
- Get acclimated. Limit time spent working or exercising in heat until you're conditioned to it. People who are not used to hot weather are especially susceptible to heat-related illness. It can take several weeks for your body to adjust to hot weather.
- Be cautious if you're at increased risk. If you take medications or have a condition that increases your risk of heat-related problems, avoid the heat and act quickly if you notice symptoms of overheating. If you participate in a strenuous sporting event or activity in hot weather, make sure there are medical services available in case of a heat emergency.
