Scientists recommend using humidifiers to avoid the high risk of contracting the SARS-CoV-2 coronavirus indoors, reports Science Alert.
According to Linsey Marr of Virginia Polytechnic University, humidity needs to be kept above 40 percent, but below 60 in the winter months. Under these conditions, the virus does not survive, and the body’s defense system, including the mucous membrane of the respiratory system, works better than in dry air.
Aerosol researcher Ajit Ahlawat and colleagues have shown that the likelihood of airborne transmission of coronavirus is higher in dry areas than in wet areas. This is due to the fact that viral particles remain in the air with low moisture content and retain the ability to infect longer. In humid air, the lipid membrane of the coronavirus is destroyed faster, which inactivates the pathogen.
Higher temperatures can also inhibit the spread of the virus through surfaces, although this type of transmission is rare. In addition, scientists advise against maintaining excessive humidity, as it can promote mold growth, causing asthma and allergic reactions.
