#Hydrating the respiratory tract: an alternative explanation why masks lower severity of #COVID-19
The seasonality of respiratory diseases has been linked, among other factors, to low outdoor absolute humidity and low indoor relative humidity, which increase evaporation of water in the mucosal lining of the respiratory tract. We demonstrate that normal breathing results in an absorption-desorption cycle inside facemasks, in which supersaturated air is absorbed by the mask fibers during expiration, followed by evaporation during inspiration of dry … Continue reading #Hydrating the respiratory tract: an alternative explanation why masks lower severity of #COVID-19
