Today, masks have become an indispensable supplies in life. But in the hot summer, can you wear a cool mask? Ordinary masks are monotonous, can you wear something good? The reporter's investigation found that the mask on the market was no longer blue and white "divided the world" -not only colorful color, but also printed with elements such as plants, animals, characters, texts, etc. Flatus, etc., rich in shape and beautiful style, loved by young people.
"There is no problem to print the mask and cartoon characters, but it is necessary to consider that the manufacturing process of the mask will cause the mask to be worse." Wu Sheng, deputy director of the Senior Disease Control Office of Beijing Tsinghua Chang Geng Hospital, told reporters that the mask of the mask was There are many relatively uniform holes in the non -woven fabric. After the pattern is printed, if the coatings and dyes in the process cause these holes to be closed, then it is like spraying paint and obsessed, which may affect the comfort of the mask.
The dazzling printed mask meets people's aesthetic needs, but in summer, everyone has more sunscreen demands. The online shopping platform has launched many masks with cool and breathable functions, such as the eye protection corner of the eye to prevent UV -proof blue light silk mask, ultra -thin single -layer 3D stereo mask, velvet tulle breathable mask ...
Is this kind of breathable covering pipe with sunscreen effect? "No matter what material, structure and shape design, be sure to see if the mask obtains national certification." Wu Sheng introduced that there are generally two ways to improve the breathability of the mask, that is, make the hole larger or more. "If you use the method of many holes to achieve breathable, you can still block some harmful substances; if it is only a large hole, it may reduce its protective effect."
There are also many "ice masks" on the market. In Wu Sheng's view, the discomfort of wearing ordinary masks in summer may be psychologically, not physiological. "In the past, many women also wore masks in summer, which did not affect daily activities. Some people even wore only two masks that revealed two eyes. In fact, some people like to wear cotton masks. The ordinary surgical mask is good, but people feel that they are more comfortable from psychologically. "
Recently, many brands have launched new electric masks, which claims to block the droplets, and can also filter PM2.5 particles, while solving the problem of poor breathing that ordinary masks may bring. Can you really achieve this effect? "If you send the wind in the mask, there is no problem. If it is rowing outward, it cannot be worn, and its cooling is not significant." Wu Sheng reminded that although the electric mask has certain protection effects, the electric mask is not related to the related related correlation. Standards and excellent effects, so it is not recommended to use electric masks in high -risk fields such as hospitals in special areas.
In addition to introducing new heatstroke prevention and cooling masks, many e -commerce companies have also launched the mask to assist the "artifact" -nasal support, brackets, anti -fog bars ... "These internal support or external products have a certain supporting effect, but it is also accompanied by damage. The risk of mask sealing has reduced the protection effect. "Wu Sheng reminded," To use these products, you should pay attention to ensure the closure of the mask -the mouth and nose can be covered, and the edge of the mask must fit the face. After it is raised, let the mask have a large gap, and even the nose is exposed outside the mask. "
In response to long -term wearing masks, there is a smell of odor, and the shopping platform has also launched "fragrant" products such as masks, cool stickers, and aromatherapy buckles. In this regard, Wu Sheng suggested that everyone should change the mask. "Regular replacement is because the pores are easy to block for a long time, and the second is that the moisture we exhaled will wet the non -woven fabric, which is easy to bring in bacteria and viruses. For ordinary people, the probability of contacting the pathogen is lower. Change every day and change it every two or three days, but the mask must be dried in the ventilation place, it is best to have the sun. "
Wu Sheng particularly reminds that how to choose and wear masks should be based on reducing the risk of virus transmission and protecting their own safety and health. Regardless of the "fancy mask" or "anti -stuffy artifact", it should be carefully identified.
