How to prevent heatstroke and cool down in hot weather requires everyone to do a good job in many aspects.

1. Drink plenty of water, but don't drink ice or sugar. In hot weather, no matter how much you exercise, you need to increase your liquid intake, and you can't wait until you are thirsty to drink water. If you need to do manual labor or strenuous exercise in a high temperature environment, drink at least 2~4 cups of cold water (500- 1000 ml) every hour. The water temperature should not be too high. Drink more water.

Don't drink or eat too much sugar in hot weather. These drinks will cause the human body to lose more body fluids. At the same time, avoid drinking too cold frozen drinks to avoid stomach cramps. For some patients who need to limit liquid intake, the amount of drinking water at high temperature should be in accordance with the doctor's advice.

2. Pay attention to supplement salt and minerals. Excessive sweating will lead to the loss of salt and minerals in the body, and the lost salt and minerals must be supplemented to meet the normal needs of the human body. Sports drinks can help people replenish the salt and minerals they need when sweating. If you are on a low-salt diet, you should consult your doctor before drinking sports drinks or eating salt tablets.

3. Eat a light and nutritious diet to ensure adequate sleep. Eat less high-oil and high-fat foods and try to eat lightly. Indigestible food will bring extra burden to the body. However, it should be noted that people need to consume enough calories, supplement protein, vitamins and calcium, and eat more fruits and vegetables in high temperature environment. Ensure adequate sleep and avoid direct blowing by electric fans or air conditioners when sleeping.

4. Wear appropriate clothes and sunscreen. Outdoor, you should try to choose thin, loose and light clothes. If you must do outdoor activities, you should pay attention to sun protection and cooling. You can wear a sun hat and wide-brimmed sunglasses and apply SPF 15 sunscreen.

05

Plan your trip and avoid going out at noon. Try to avoid going out in hot weather. If you must exercise outdoors, it is best to avoid noon, try to arrange the time in the morning or evening, try to exercise or rest in the shade, and avoid direct sunlight.

If you need to walk or exercise in high temperature, please don't do strenuous exercise immediately. You should start slowly, gradually increase the intensity and adapt your body to the external environment. When you feel your heartbeat is getting worse and you feel chest tightness, especially dizziness, confusion, fatigue or even syncope, you should immediately stop all activities and quickly find a cool or ventilated place to rest.
