It is very hot to play indoor badminton in summer. What's going on?

It should be caused by the high temperature. One thing to remind you: indoors: it is best to turn on the air conditioner at 26℃ or 27℃

In today's weather of 40℃, I'm afraid no one will practice badminton outdoors. "It is not recommended to play outdoors, which is easy to get heatstroke." Gao Zhihong suggested with a professional eye, "In summer, the ultraviolet rays in the sun are particularly strong, and skin exposed to the scorching sun for a long time will cause burns of 1~2 degrees, and heatstroke will occur. Ultraviolet rays can also penetrate the skin and bones, radiate to the meninges and retina, and cause damage to the brain and eyeballs. So be sure to bring a sun hat, sunglasses, sunscreen, towels, etc. Go to general activities. "

Then, how about playing badminton indoors? What will happen if the air conditioner is turned off? "It is best not to play for more than half an hour. In this weather, there is no air conditioning indoors, which is not only a heat problem, but also a heatstroke phenomenon. " Gao Zhihong suggested that it is best to carry out badminton activities in air-conditioned venues. Even if there is some air conditioning, amateurs will not have much influence. "It is best to turn on the air conditioner at 26℃ or 27℃, which is too low. Once it is still, it is easy to catch a cold. "
