Zhang Wenhong said that you can turn on the air conditioner and wear a mask in hot weather. What happened?

18 night, Dr. Zhang Wenhong said in the live broadcast that the epidemic prevention and control in China is very good, and the probability of COVID-19 infection is very small when people wear masks. You can turn on the air conditioner and wear a mask when it is hot, but you still have to open the window.

The weather is getting hotter and hotter. Test results show that the temperature rise of wearing N95 mask is nearly twice that of medical mask. Dr. Wu, deputy director of the emergency department of Chaoyang Hospital, said that the main purpose of wearing masks is to prevent the spread of droplets, and ordinary medical masks can completely play a protective role. The N95 mask is highly airtight, but if you walk or ride a bike for a long time, the person wearing the mask will be in a state of insufficient oxygen supply, and there will be some hypoxia.

Dr. Wu suggested that ordinary medical masks can play a protective role in daily office environment.

Extended data:

Dr. Wu suggested that if you need to wear masks all day, in hot weather, it is best to prepare more masks and change them at any time to reduce the secondary pollution of masks.

In addition, before wearing the mask for a long time, you can apply emollients on the bridge of the nose, cheekbones, ear roots and other parts to keep the skin smooth and reduce the damage caused by friction. The wearing position of the mask should be changed properly every one or two hours to reduce local pressure. If conditions permit, you can apply a cold towel to your face.

China Net-Zhang Wenhong said that you can turn on the air conditioner and wear masks in hot weather, so you should pay attention to sun protection to avoid creating masks.
