How do you choose masks?

As the hazy days continue, netizens have humorously shared: "It's not a dog, but there's a leash in his hand, and the dog is nowhere to be seen. The dog called me to go." In response to this, a new 16-character Jiangsu spirit emerged: "Houde Zaiwu, self-improvement, don’t suck, work hard, and create something again." The persistent smog has brought a lot of inconvenience to daily life and seriously impacted our health. As a result, many people now wear masks when going out. But do you really know how to choose the right one?

First, gauze and disposable masks are not effective against PM2.5. These masks are mainly designed for larger particles like PM3 or above. They offer little protection against finer particles such as PM2.5, which can easily penetrate the mask and enter the lungs.

Second, is a tighter mask always better? While it’s true that more protective material can block more particles, a mask that’s too tight can make breathing difficult. This can lead to dizziness due to insufficient oxygen intake. For example, wearing an N95 mask for long periods might cause discomfort, especially for those with heart conditions. It’s important to be cautious and take breaks if needed.

Third, proper cleaning and care are just as important as choosing the right mask. Whether you’re using a cloth mask or a disposable one, it’s essential to clean and disinfect it daily. Boiling the mask for a few minutes and then drying it in the sun helps kill bacteria and keep it hygienic. Also, make sure to store your mask in a clean bag after use, avoid flipping it over, and don’t wear it for extended periods. Prolonged use can reduce its effectiveness and increase the risk of infection.

Additionally, it’s worth noting that the body naturally warms the air we breathe before it reaches the lungs. This process helps protect the respiratory system. However, wearing a mask for too long can prevent this natural function from occurring, potentially weakening the nasal mucous membranes over time. As a result, people may become more susceptible to colds and other respiratory issues.

In conclusion, while masks are essential during smoggy days, it’s important to choose the right type, wear it correctly, and maintain good hygiene practices. Balancing protection with comfort and health is key to staying safe without compromising your well-being.
