* increased viability of the influenza virus (A and B) on exposed surfaces (doorknobs, countertops, etc.) in low humidity and low temperature conditions
* cold temperatures lead to drier air, which may dehydrate mucus, preventing the body from effectively expelling virus particles
* effect of vitamin D levels on immunity to the virus [2]; vitamin D levels fall when people stay out of the sun.
