The following excerpt is from an article by Toby Graham posted by our friends at KPA.io:
According to a new study in the American Society for Microbiology’s journal mSystems, fresh air and sunlight can reduce the spread of the coronavirus. Researchers at the University of California, Davis and the University of Oregon found that “increasing the amount of air flowing in from outside and the rage of air exchange can dilute virus particles indoors.”
“Virus particles like drier air, so maintaining a high relative humidity can help. Virus-bearing droplets get bigger in humid air, meaning the settle out more quickly and don’t travel as far. Humidity also seems to interfere with the lipid envelope around viruses such as SARS-CoV-2. Too much humidity, however, can promote mold growth.”
Please note that better airflow is not a complete virus mitigation strategy unto itself. You’ll still need to make sure employees are washing their hands frequently, keeping their distance from others, cleaning and disinfecting shared surfaces regularly, and following other guidelines from local health authorities. But with proper ventilation and sunlight, they can do all that in a brighter, happier, slightly less dangerous environment.
Turns out Grandma was right again! Fresh air and sunshine are important for good health – even indoors.
