Airing out effectively prevents droplet spread indoors.
When someone coughs or sneezes, most droplets fall to the ground. Most of these droplets, so-called microdroplets, can remain in the air for some time, which is why the risk of infection is higher indoors and when many people are gathered in small spaces for longer periods of time.
Therefore, you can prevent the spread of infection and reduce the concentration of airborne microdroplets by ventilation and creating a cross draft by opening windows and doors.
You can increase ventilation by:
- Creating a cross draft by opening windows and doors
- Opening windows and doors for 5-10 minutes 4-5 times a day
- Airing out more often if several people are gathered indoors, for example before and after you have had guests in your home
- Creating a draft every hour if you are together for an extended period of time
Intermittent draughts only affect room temperature temporarily and do not increase energy consumption.
