German Chancellor Angela Merkel recently recommended a simple and accessible protective measure against the new coronavirus: regular room ventilation. Silviu Gurlui, professor at the Iaşi Faculty of Physics, explained to Digi24 why this measure is effective and can protect us from COVID-19 infection. All the more so since many Romanians avoid keeping all the windows open, for fear of the “draft”.
„This virus is adapted to environmental conditions. Where there are more viruses, we must intervene and the simplest solution – which also applies in Germany – is to ventilate that building, that space, because it leads to the spread of the virus and its number per cubic centimeter is reduced. and then the probability of getting infected is significantly reduced, “Gurlui said.
„Ventilation is within our reach and should be done periodically or as often as possible so that we can spread the virus and freshen the air in the home or office. It is very important, he added.
The teacher also spoke about the situation of rooms without windows and where air conditioning is used.
„I saw that there are many traders that have been adapted to manufacture equipment to refresh the air, to clean it of this type of particles. There are many solutions, if necessary, but it is preferable to find solutions to have very good ventilation conditions. It is important during this period to always be clean, ”he said.
Gurlui says that natural light is also important.
„There are gifts of nature that we must use suitable. In addition to this ventilation, it is very important to create the conditions for natural light to enter the room, especially UVA light. It helps a lot and is a gift, a solution that is available to everyone. That is why I recommend that in the students’ classes, whenever possible, they choose those classes that are better lit and those intervals of time in which there is more light ”, he explained.
Regular ventilation in all public and private premises can significantly reduce the risk of infection, “said the German government. which strongly encourages people to ventilate rooms, given that according to some studies, no less than 90 percent of COVID-19 patients have received the virus from poorly ventilated places.
For maximum efficiency, “cross ventilation” is recommended, that is, simply opening all the windows in a house or apartment to allow for drafts and thus a complete renovation.
However, many Romanians They are reluctant to naturally air the rooms. “northdraws the flow ”is a myth well ingrained in popular belief, which, however, has no cover in reality, explained Dr. Mihai Craiu to Digi24. In addition, he says that air conditioning in COVID is much more dangerous in communities, so especially in schools and offices it would be good to keep it closed, if natural ventilation is not possible.
“It just came to our knowledge then. Most people are frightened by drafts as a potential source of airborne infections and colds, from the simplest to pneumonia or otitis. Microbes cause these diseases. In principle , air currents have a really beneficial effect from a respiratory point of view, because they do not allow the accumulation of a concentration of inhalable particles, which we can see, on the dust, but also some things that we cannot see. A room without ventilation it is more dangerous when it comes to reducing oxygen and increasing carbon dioxide than wearing a mask. In our country, as I said, we are afraid of the current, from public transport to classes and we keep the windows very tightly closed, even when it’s hot, ”said pediatrician Mihai Craiu on Digi24.
