There are several natural methods to lower your body temperature, whether you're looking to cool off or reduce a fever. Start by staying hydrated and eating foods rich in water. You can also try home remedies like foot baths or warm showers. However, in cases of heat stroke or high fever, immediate medical attention is needed. If you experience severe symptoms, it's crucial to contact emergency services right away.
Steps
Quick Response

Wear loose-fitting, light, and light-colored clothing. If possible, remove layers of clothing. Thin, breathable fabrics like silk, chiffon, lightweight cotton, and linen are the best choices for hot weather. Additionally, try to wear white or light-colored clothes, as these can help reflect sunlight and keep you cooler.

Sit in front of a fan or air conditioner. If possible, find a place with air conditioning. If your home doesn't have one, go out to public places like grocery stores, movie theaters, or a friend's house. At the very least, you can cool down by sitting in front of a fan.
- If you only have a fan, try moistening your skin with cool water while sitting in front of the fan. The water on your skin will provide a refreshing feeling, and you'll feel cooler as it evaporates.
Use a gentle and slow hand fan movement. If you don’t have air conditioning or an electric fan, you can fan yourself to help reduce body heat. It’s important to use a fan (or any object that can work like one) with a wide surface, avoiding vigorous fanning.
- If the fanning is too fast, your blood will rush to the surface and make you feel warmer. A gentle motion will help sweat on your skin evaporate and lower your temperature.
- Moisturizing your skin with cool water while fanning is also a helpful method.

Try using relaxation techniques. Sit comfortably and take slow, deep breaths. Inhale for a count of 4, hold your breath for a count of 7, and exhale for a count of 8. Practice controlled breathing for at least 10-15 minutes to lower your heart rate and reduce body temperature.
- If it helps, you can listen to relaxing music or nature sounds like waves or whale songs.
- Try meditating. You can find guided meditation sessions aimed at relaxation on YouTube and other services.
- Relaxation methods can make you feel cooler if you are experiencing a hot flash.

Soak your feet in cold water. Fill a small basin with cold water and ice, and soak both feet in it. For the best results, soak them for at least 60 minutes.
- If you just want to cool off a bit, you can soak for as long as you like. However, if you need to lower your body temperature (e.g., from a fever), soak for more than 60 minutes. Soaking for less than 60 minutes won't effectively reduce your temperature.
- Change the ice or add more cold water when the water starts to warm up.

Take a warm bath or sponge off with a wet cloth. If you want to reduce a fever, a warm bath is better than a cold one. You may start shivering when you soak in cold water, which can raise your body temperature.
- If you don't have a bathtub, try using a damp sponge, washcloth, or piece of cloth to wipe your body.
- Turning on a fan while bathing or wiping yourself down is also a good idea.
Stay Cool with Food and Drinks

Drink small amounts of cool water frequently. Drinking water is a great way to lower your body temperature and replenish fluids lost through sweat. It's more effective to drink 180-240 ml every 15 minutes than to drink a large amount all at once.
- Drink cool water instead of ice-cold water. Very cold water can cause stomach pain or headaches.

Drink sports drinks. If you're exercising in hot weather, grab a sports drink to rehydrate. Sports drinks will replenish both water and essential salts and minerals lost through sweat.
- Maintaining proper hydration is crucial, so avoid sodas and drinks containing sugar, alcohol, or caffeine. These drinks can raise your body temperature and contribute to dehydration.
- You might also try electrolyte drinks like Pedialyte.
- Make sure to choose sports drinks that aren't energy drinks, as they may contain caffeine, which can increase heat production in the body.
- Also, be mindful of the sugar content in sports drinks. High sugar means more calories, which will accumulate with each drink.

Suck on ice cubes. Besides feeling refreshing, sucking on ice cubes can help reduce body temperature, preventing heat exhaustion and heat stroke.
- Remember, you still need to hydrate. A few ice cubes won’t provide as much hydration as a full glass of water.

Eat water-rich foods. Foods with high water content can help lower your body temperature. Watermelon, cucumber, and leafy greens are excellent choices.
- Water-rich foods are also easy to digest, meaning less energy is used during digestion, which generates less heat in the body.

Tránh rượu bia, caffeine và đường. Khi cần làm mát cơ thể, bạn sẽ rất dễ bị cám dỗ tìm đến bia lạnh, cà phê đá, trà đường hoặc nước thể thao (một số loại nước thể thao có thể chứa hàm lượng cao caffeine và đường). Tuy nhiên, các thành phần này khi được uống vào sẽ gây mất nước, tăng nhiệt trên da và ngăn cản khả năng kiểm soát nhiệt của cơ thể.

Tránh các thức ăn chứa hàm lượng cao chất béo, protein và carbohydrate. Nghe có vẻ ngược đời, nhưng món kem lạnh rốt cuộc sẽ khiến bạn ấm lên, mặc dù tạm thời cũng giúp bạn mát hơn trong thời gian ngắn. Chất béo, protein và carbohydrates đều đòi hỏi nhiều năng lượng hơn trong quá trình tiêu hóa. Năng lượng nhiều hơn cũng có nghĩa là nóng hơn.
- Các thực phẩm khác nên tránh khi đang nóng bao gồm thịt đỏ, quả hạch và gạo lứt.
Xử lý các trường hợp cấp cứu

Gọc bác sĩ nếu bạn bị sốt cao hoặc các triệu chứng nghiêm trọng. Sốt cao trên 40 độ C là tình trạng đáng lo ngại ở cả người lớn và trẻ em. Đối với trẻ sơ sinh dưới ba tháng tuổi, bạn cần gọi cho bác sĩ khi trẻ sốt trên 38 độ C.
- Các triệu chứng nghiêm trọng khác bao gồm co giật, mất ý thức, lú lẫn, cứng cổ, khó thở và đau dữ dội.

Gọi cấp cứu khi thấy một người có các dấu hiệu sốc nhiệt. Sốc nhiệt là tình trạng nghiêm trọng hơn cảm giác nóng hoặc căng thẳng do nhiệt và cần phải được chăm sóc y tế khẩn cấp. Các dấu hiệu sốc nhiệt bao gồm thân nhiệt tăng cao trên 40 độ C, lú lẫn hoặc kích động, buồn nôn và nôn, thở nhanh, tim đập nhanh và đổ mồ hôi bất thường.

Move the heatstroke victim to a cooler place. While calling for emergency services, take the victim to the shade. If possible, move them into a building with air conditioning or a fan.

Apply ice packs to the neck, groin, and armpits. Following the advice of emergency dispatch, you should cool the victim while waiting for the ambulance. Applying ice packs or cold towels is an effective method. A cold shower can also help lower body temperature, but make sure the victim doesn't start shivering.
- If you're outdoors, the best option might be a water hose or a nearby body of water, like a river or lake.
