Trotec practical knowledge: Tips for a better indoor climate 3/7 – How to avoid dry indoor air and reduce corona infection risks

In the last few weeks, winter has once again made us feel what ‘really cold’ means. Many people at home have turned the heating knobs all the way to the left – and are now suffering from the consequences of dry heating air. It dries out our mucous membranes, reduces their cleansing function and creates an ideal habitat for viruses. It also causes undesirable effects such dry nose and irritated eyes, as well as coughs, colds and sore throats. Because low humidity also increases the lifetime of infectious corona aerosols in the room air, there is virtually every reason to humidify the air as much as possible in the future.

Trotec practical knowledge: Tips for a better indoor climate 2/7 – How to ventilate your room correctly and sustainably

Rarely has there been so much talk about ‘ventilation’ as in the past and current year. No wonder, since the exchange of air in rooms was and still is considered a tried and tested means against potential corona virus load caused by infectious aerosols. So far, there is no measuring device that is able to prove the contamination of indoor air by SARS-CoV-2. However, it is possible to determine a necessary ventilation interval via the ‘detour’ of a permanent measurement of CO2 values. Because the more people are in living rooms, office spaces, production rooms, schools and daycare centres, the more the exhaled carbon dioxide level increases – to the point of a CO2 alarm: time to open all the windows!

Why can winter worsen the corona pandemic?

The dreaded second corona virus wave has arrived just in time for the beginning of the cold season. Since the start of the pandemic epidemiologists and virologists have been warning us of the effect winter can have, whereby the cold weather outside keeps people in their homes, spreading the virus more and more indoors in closed rooms. For example, after analysing contact tracing, a study by Japanese researchers found that people that people are 19 times more likely to become infected indoors than outdoors.

Scientists have demonstrated: too little humidity in indoor air increases the risk of coronavirus infection

Who had even heard of ‘aerosols’ a year ago? It is now clear that these long-living infectious particles floating in the air are responsible for the majority of Corona infections. The renowned aerosol specialist Prof. Dr. Alfred Wiedensohler from the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig warns that “in cold and temperate climates, the indoor climate is usually very dry during the heating season. This could promote the spread of coronaviruses”. This is because at higher air humidity, the droplets grow faster and fall to the ground earlier, and can therefore be inhaled less by healthy people.
