Many people continue to wear personal protective equipment outside. However, as it turns out, this should not be done in cold weather. Immunologist Vladislav Zhemchugov said on the air of the NSN that the mask cools down and gets wet very quickly in the cold.
“It practically reduces it to zero. In a frost of 5-10 degrees, the virus lives for a second and cannot spread, as droplets of saliva immediately freeze, – said the specialist. – In principle, even in warm weather, the masks on the street did not matter if there was no large crowd of people. And in winter, masks on the street are even harmful, as condensation will accumulate in them, which interferes with breathing and increases the chance of infection with microbes.
