Do a good job in heatstroke prevention and cooling, and understand what can cool down and what can prevent heatstroke. Eat more fruits, such as watermelon and some fruits with high vitamin C content, and keep some heatstroke prevention and cooling drugs: Huoxiang Zhengqi Water, Cool Oil, Ren Dan, etc. Just in case! Save some tea, such as sour plum soup, strong tea, mung bean soup, etc., for better heatstroke prevention and cooling effect. Avoid hot and cold. If you come out and blow into the cold air conditioner just after sweating, or wash your face and take a bath with ice water, you will be comfortable for a while, and the consequences will only be at your own risk.
