I don’t feel any difficulty breathing when I wear a mask?

Friends who feel this way are probably not wearing the mask correctly... If you still feel comfortable breathing after wearing the mask, you should check whether the shape of the metal nose clip on the bridge of the nose has been pressed to fit the bridge of the nose and chin. Is there an air leak? If the mask is worn correctly, there should be some obstruction when breathing. If your glasses fog up when you wear a mask in winter, it means that the bridge of your nose is probably not adjusted properly.

Masks and cotton swabs contain graphene, will it harm your health?

Most of the so-called "graphene masks" currently on the market are gimmicks. For example, a certain "biomass graphene" raw material has been found to be processed from straw. It is worth noting that some mask materials use nanoscale activated carbon, and there is indeed a risk of inhaling particles when wearing activated carbon masks for a long time. For daily epidemic prevention, the public should choose protective masks that meet national standards. As for cotton swabs, adding graphene or activated carbon is nonsense.

The higher the protection level of the mask, the better?

Not necessarily. Ordinary people do not necessarily need to wear N95 or above standard masks in their daily lives.

For the masks we wear every day, the first choice is ordinary medical masks, such as N95 or masks with higher filtration performance, which are more suitable for professionals in high-risk environments. Ordinary people are prone to discomfort if they wear N95 masks for a long time. In addition, people who are already prone to difficulty breathing, such as smokers, emphysema patients, obese people, etc., wearing N95 masks will make their breathing problems worse and even aggravate.

In addition, for patients with certain lung diseases such as pulmonary fibrosis, wearing a mask may indeed affect blood oxygen. However, such patients are more likely to develop critical symptoms when infected with the new coronavirus, so if you need to Wearing a mask for a short period of time in closed public places has more advantages than disadvantages.

In fact, when we ordinary people choose for daily use, we only need to pay attention to the implementation standards of masks. For example, medical surgical masks correspond to YY0469-2011; disposable medical masks correspond to YY/T0969-2013, one time GB/T 32610-2016 for sexual protective masks, which is also the "national standard". In addition, masks for children should comply with the requirements of GB/T 38880-2020. In addition, when choosing N95, KN95 and above masks, be careful to avoid models with breathing valves.

You must shake the mask before wearing it, otherwise the residue on the mask will cause cancer?

Qualified medical masks do not have this risk. The mask can absorb ethylene oxide used in disinfection. Although ethylene oxide is a type of carcinogen, the toxicity depends on the dose. According to national standards, masks are safe if the residual ethylene oxide content does not exceed 10μg/g. After manufacturers use ethylene oxide to sterilize masks, they will wait until the residual amount is qualified before leaving the factory. In addition, residual ethylene oxide will naturally evaporate during the circulation process. Therefore, masks that meet national standards can be used normally, and there is really no need to shake them a few times.

Finally, to summarize, for ordinary people to prevent COVID-19, it is recommended to wear protective masks that meet medical standards or national standards. For healthy people, such masks do not bring risks. Even though the COVID-19 epidemic is recurring and new mutant strains are emerging one after another, correctly wearing a mask is still a simple and effective daily protective measure.
