Opening your bedroom window at night reduces the risk of coronavirus infection by 50% – this is the result of research by British scientists quoted by national media. It turns out that poor airflow increases the risk of catching Covid-19. The problem is that the smog season has already begun in the south of Poland when the air quality is deteriorating day by day, so it is not advisable to ventilate the rooms. “The main recommendation at this time is to close the windows at night” – emphasizes Ewa Lutomska from the Krakow Smog Alert.

British scientists are cited by, among others Radio Zet. Researchers point out that poor airflow increases the risk of catching Covid-19. It turns out that airborne Coronavirus particles can travel in microscopic aerosols over a distance of over two meters. The report says that by improving ventilation and increasing air circulation by opening windows, exposure to the virus is cut in half.
The problem is that in many cities and villages – especially in southern Poland – the smog season has just started, their inhabitants burn coal and wood in stoves to heat their homes. This makes the air very polluted again. Representatives of the Krakow Smog Alert (KAS) warn to choose other methods in the capital of Małopolska and neighboring municipalities that will reduce the risk of infection with a dangerous virus than the one suggested by scientists.
The conditions outside the window should be taken into account. Not only in Krakow, but also throughout Poland, because the problem of air pollution affects the entire country. The smog season has already started and one of the recommendations at that time is not to ventilate the apartment when there are high concentrations of suspended dust.

Air Quality in Krakow is deteriorating
In fact, the air quality in Krakow has deteriorated more and more in recent days. Particularly at night, the permissible standards are exceeded significantly. The concentration of PM 10 dust has recently been well above 100 micrograms per cubic meter (the acceptable daily standard is 50 µg / m3).
In Krakow, I do not recommend anyone to open windows at night. Air quality is actually deteriorating, the main reason being that residents of neighboring municipalities start heating their homes with coal and wood in the afternoon. And as we know, Krakow is located in a basin, these pollutants flow down to us and the air is of very poor quality at night

Invest in air purifiers!
If someone really wants to ventilate the room, it is rather during the day. – But before that, let’s check the air quality. In Krakow, the availability of tools for this purpose is high – emphasizes Lutomska. And he adds that, especially in autumn and winter, it is worth getting an air purifier, which can be an alternative to airing your apartments and houses.
