First, buy a special anti-fog mask. The reason why smog is easy to harm human health is because there are a lot of PM2.5 particles in it, so small that it is difficult for you to cover your nose and mouth to stop it from entering the human body. Instead, buy a special anti-smog mask, also known as PM2.5 mask, which is extremely airtight and can filter out dust and bacterial particles that we can't see in the air, thus avoiding the transmission mode of inhaling smog. Of course, everyone should also pay attention to the need to change the mask after two days of use. Don't use the mask for a long time to save money, which can't guarantee the wearing effect of the mask.
Choose the right time to go out. We know that even if there is smog, there will be different conditions in one day, so it is very important to choose a relatively good time for smog, and the choice of time is also regular. Usually, the smog in the morning is more serious, because pollutants in the air are easy to gather at night, and when the temperature drops to a minimum in the morning, condensed water vapor will form more serious smog. Friends who have the habit of running in the morning had better not go out at this time. When the sun comes out and the temperature rises, it forms the smog blown away by the wind. It is relatively appropriate to go out at this time.
Smog prevention is very important, and everyone must pay attention to it. Some people think that smog means inhaling some dirty things, which will not affect the body. Actually, it is not, because these tiny particles are inhaled into the lungs and respiratory tract, which will be harmful to the body for a long time.
