Why is fresh air so important?
Making sure there is good ventilation in a room is something we sometimes overlook, but it’s one of the basic measures we should all be taking to reduce the risk of catching or spreading coronavirus (COVID-19).
When a person infected with coronavirus coughs, talks or breaths, they release droplets and aerosols which can be breathed in by another person. While larger droplets fall to the ground quickly, smaller droplets and aerosols containing the virus can remain suspended in the air for some time indoors, especially if there is no ventilation.
Opening windows to bring in fresh air from outside is important. The more fresh air there is to breathe, the less likely a person is to inhale infectious particles.
With roughly one in every three people with coronavirus not showing any symptoms of having it, it’s important to take every precaution, and remember that good ventilation is one of those measures.
