Sunlight as a dietary supplement #HealthHack

Our daily lives of being confined to the brutal ritual of “AC Home – to – AC Car – to – AC Office” has a surprise stealthy demon lurking in it, and it is called “the lack of sunlight” and to be specific “the lack of natural Vitamin D”.
Researchers at NBER in  Working Paper No. 24340 have investigated whether sunlight affects influenza incidence. Influenza is a highly contagious viral infection and a great public health hazard.

The researchers conclude that their study “reinforces the long-held assertion that vitamin D protects against acute upper respiratory infections.” With sunlight serving “as an alternative, natural path through which humans can and do secure vitamin D,” something as simple as a walk outdoors on a sunny day can offer protection against influenza.
