The weather is getting hotter and hotter, and many office workers wearing masks are miserable. The test results are as follows: The temperature of the cheeks inside the mask can reach 34°C to 35°C. Among them, wearing N95 masks warming up nearly twice that of medical masks.

In a ventilated room with a room temperature of 25°C, and without a mask, the skin surface temperature on the cheeks is generally 32.4°C. After wearing the mask, the temperature of the cheek rose by 0.1°C; after 9 minutes, the temperature of the cheek rose to 34.1°C. After 13 minutes, the temperature of the cheeks rose to 34.3°C. Since then, the cheek temperature has been maintained between 34.1℃ and 34.3℃.

Subsequently, a control measurement of the N95 mask was carried out. At the beginning, the temperature of the cheeks was 33°C. After wearing the N95 mask for 3 minutes, the temperature of the cheek rose to 34.8°C. Over time, the temperature of the cheeks continued to rise, and after 13 minutes, the temperature of the cheeks rose to 36°C. Since then, the temperature on the cheeks has been maintained between 35.5°C and 36°C.

Should ordinary medical masks be worn during the hot season? From a professional point of view, not everyone has to wear N95 masks. The main purpose of wearing a mask is to prevent the spread of droplets. Ordinary medical masks can completely play a protective role. N95 masks have high airtightness, but if you walk or ride a bicycle for a long time, the mask wearer will be in a state of insufficient oxygen supply, and there will be a certain lack of oxygen.

If you need to wear masks throughout the day, in hot weather, it is best to prepare a few more masks and replace them at any time to reduce the secondary pollution of the masks. In addition, before wearing a mask for a long time, you can apply emollients to the bridge of the nose, cheekbones, and ear roots to keep the skin smooth and reduce friction caused by friction. Every one or two hours, the position of the mask should be changed appropriately to reduce local pressure. If possible, you can put a cold towel on your face.
