How to wear a mask in summer and feel difficult to breathe?
Judging from the current situation of epidemic prevention and control, wearing a mask is still an effective protective measure. If the weather is hot and you feel that you can't breathe well, you can take off your mask at home or in an open outdoor place to breathe.
If you are in a crowded and poorly ventilated place, it is not recommended to take off your mask even if you feel stuffy, so as to avoid direct exposure of your mouth and nose to possible adverse environment.
When should I wear a mask? 1. For the general public, it is unnecessary to wear masks at home. If they are in a well-ventilated outdoor place in a low-risk area and keep a certain social distance, they can also take off their masks.
2. When traveling, if you drive by yourself, there are no strangers in the car or have a history of epidemiological contact, you don't need to wear a mask, but you need to wear a disposable medical surgical mask when you take a long-distance bus, train, ship, plane, etc.
3. When entering supermarkets, cinemas, museums and other places, you should consciously wear medical surgical masks.
How long the shelf life of the mask depends on the situation.
Generally speaking, ordinary medical masks and surgical masks can be kept for about 2-3 years without being opened, while in the case of opening, the shelf life of masks with low protection level is about 5-7 days, and those with high protection level can be kept for about 10-20 days.
Masks should be stored in a dark, hygienic and dry place. It is recommended to choose independent packaging when purchasing. If it is a large package mask, try to put it in a medicine box or a sealed bag after opening.
How often do you change the mask in summer? 1-2 hours.
Generally speaking, it is recommended to change disposable medical surgical masks at least every 4 hours. The longer you wear it, the worse the protective ability of the mask. Due to the sultry weather in summer, it is recommended to change the mask every 1-2 hours.
When the mask is soaked by sweat, the protective effect will become worse, and COVID-19 cannot be effectively prevented. Therefore, it is best to prepare more masks when going out in summer for easy replacement.
