Ever since we were children, we have known that the home must be regularly ventilated in order for fresh air to enter. But after the start of the pandemic, comments about the need to ventilate the premises began to come from every expert
How important is it, does ventilation help protect against coronavirus and how often should you ventilate your room in general?
How to ventilate the room
Usually the air outside the room is much cleaner than the air inside. Therefore, ventilating the place where you study, work or live is an easy way to breathe more fresh air and feel better.
How often is it needed? According to the WHO, polluted air kills several million people worldwide every year. People who live in rooms that are heated with wood, coal or even treated manure are at the greatest risk. Although in a city apartment there are enough factors that worsen the air quality.

It is now clear that most often people get infected with coronavirus in closed rooms. Church, office, restaurant, dormitory are places that are not safe to visit. After all, this is where the main method of transmission of infection is realized - from person to person when talking, coughing or sneezing.
And if heavy polluted droplets quickly descend to the surface, then small particles circulate along with the air. Therefore, it is enough to be in such an unventilated room, breathing in polluted air, to catch COVID-19. And no amount of distancing will save you.
Therefore, it is necessary to ventilate rooms that are regularly visited by many people. However, ventilation is only part of prevention. This is a way to reduce risk, as is social distancing, wearing masks, disinfecting surfaces and washing hands thoroughly with soap and water.
Ventilation also helps to get rid of cigarette smoke, which easily spreads indoors and accumulates on clothes and various surfaces. Breathing such air is not only unpleasant, but also very harmful, especially for children.
It is worth ventilating after cooking on the gas stove. The reason is that nitric oxide is formed, the inhalation of which makes the body defenseless against respiratory infections. That's why you should regularly use the hood or ventilate.
How often should you ventilate
You should ventilate the room as often as possible. For example, in the summer, experts advise airing the house every hour by opening a window for 10-15 minutes. In cold weather, many forget about ventilation. But even in winter, you should ventilate your home at least 4-5 times a day for at least a few minutes.

Many fear drafts in vain. However, the common cold and COVID-19 itself are viral diseases. They are not related to the fact that a person is simply "high". But still, if there are small children in the room when you are going to ventilate, then it is better to send them to another, already ventilated room.
Of course, it is worth ventilating the house more often when there is fresh air outside. But if you live in an apartment next to a busy road, then this will not bring much benefit. Then you better grow indoor plants that help purify the air.
You can also get an air purifier at home. You just need to know that in any really efficient device there is a filter that will need to be changed regularly. If this is not done, then there will be no point in such an air purifier.
