Humidifiers Can Hinder the Flu

Outbreaks of influenza are seasonal in nature, with transmission and death rates increasing in winter months. Dry air and cold temperatures are particularly known to promote the spread of influenza, and, in temperate regions, flu outbreaks have been closely correlated with decreased humidity. While it’s previously been shown that low ambient humidity encourages the transmission of viruses, what this means for infection in humans, as well as outcomes among those infected, is less clear, leading researchers to look into whether changes in humidity could play a role in influenza infection. It turns out that altering humidity levels could be one way to not only reduce the transmission of flu, but also to bolster humans’ resistance against infection.  Read more....
