Tips for sleeping and heatstroke prevention 1, warm water bath can dissipate heat faster.

Many people think that taking a shower with cold water is more comfortable and can cool down. But in fact, showering with cold water when sweating will make the pores of the whole body close quickly, so that the heat in the body can not be dissipated and stay in the body, which is easy to cause various diseases. The correct way is to choose warm water bath, because warm water bath can dissipate heat faster, and it will make people feel refreshed after bathing.

2. It is not advisable to drink too much after being thirsty.

Drink water in time in summer, don't wait for thirst to drink water. The scientific approach is to drink a cup of cold boiled water (about 200ml) every morning, 2 -3 cups in the morning and 3 -4 cups in the afternoon. It is best to drink another cup before going to bed at night. After the elderly wake up in the middle of the night to go to the toilet, they should drink some water. It's best to drink water several times, slowly, and don't drink too much. After sweating a lot in labor and exercise, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be supplemented appropriately, because after sweating a lot, too much salt is lost in the human body, accounting for about 0.5% of sweat. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously out of balance, leading to metabolic disorder.
