The higher the level of absolute humidity in the air could, according to their research, help to reduce the incidence (and likelihood) of the flu virus.
Shaman and Kohn explain further: “In temperate regions, both outdoor and indoor AH possess a strong seasonal cycle that minimizes in winter."
They add, "This seasonal cycle is consistent with a wintertime increase in IVS and IVT and may explain the seasonality of influenza.”
They conclude, “Thus, differences in AH provide a single, coherent, more physically sound explanation for the observed variability of IVS, IVT and influenza seasonality in temperate regions.”
Although not yet proven, they hope their hypothesis will be further tested to prove its validity.
