This reduces the risk of coronavirus infection


Humid air could be a good weapon against the spread of the dreaded coronavirus. According to scientists from the RIKEN Center and the Japanese University in Kobe, higher indoor humidity can reduce the risk of spreading the infection.

“The researchers compared the amount of droplets caught on the face of a person who was sitting 1.8 meters from a sneezing person who has potential Covid-19 disease. At 90% humidity, many more droplets fell on the table next to the sneezing person than at 30% humidity, when the droplets floated further and longer, “ stated by Veronika Salayová from

Simply put, the more moisture in the air, the better. This was also confirmed by the well-known Slovak infectologist Peter Sabaka: “With higher humidity, infectious particles fall to the ground faster. The water vapor in the air is packed on them, they are heavier and fall to the ground. So they won’t fly that far. “

Similar conclusions were reached by researchers from Germany and India, who analyzed 10 studies from around the world. They found that at low humidity, the virus not only stays in the air longer, but also more easily enters the body through the dry mucosa in the human nose. “Dry air is not good because it dries the mucous membranes and could in some ways contribute to the better spread of the coronavirus.” the infectologist explained.

Studies show that the risk of coronavirus infection in dry enclosed rooms during the winter months may be greater for a large number of people living in heated rooms because heating dehumidifies the air. The use of, for example, humidifiers can therefore significantly help to reduce infection in enclosed rooms. It is therefore recommended to keep the relative humidity in the room between 40 and 60%.
