It's so sad to say in hot summer. Health experts believe that the most important thing in summer health care is to prevent heatstroke and cool down, so that you can spend the summer better. How much do you know about heatstroke prevention and cooling in summer? I am here to share some with you! One, take a bath with cold water. In summer, many people begin to love cold water bath. When taking a bath, their left foot will feel cool as never before, but cold water will make blood vessels contract, make people's immune function disorder, and make you hotter after taking a bath. The correct way is to take a bath with warm water. You may sweat during the washing, but it is more conducive to cooling down after washing. Second, applying sunscreen sunscreen too thick will also affect the effect of sunscreen. The correct way is to apply a layer, because ultraviolet rays can actually burn the skin through clouds, so the most important thing is appropriate. Third, swimming can cool down Many people think that swimming can cool down, so playing in a dedicated swimming pool is actually crowded, which is actually not conducive to cooling down. On the contrary, if you really want to take a bath at home, it is more effective to take a bath directly in your own home with warm water. Fourth, drink cold drinks to cool down. Open the frost in hot summer, pick up the cold drink and drink it. It is true that you will feel cold at the moment you drink it, but after that, you will be hotter. At this time, it is better to let yourself drink a cup of green flowers to quench your thirst and prevent heatstroke. Speaking of indoor physical cooling, I have three ways to tell you here. One is to put a basin of water indoors, the other is to turn on the electric fan, and the third is to turn on the air conditioner. You can also put a basin of water and turn on the electric fan. Close the windows during the day, or hot air will rush into the room.
