DOES SUNSHINE IMPACT THE COVID VIRUS?
We've been hearing from many public health experts and scientist that sunlight does indeed have an effect on killing viruses in a couple ways. First the UV rays from sunlight have a detrimental effect on virus cells on surfaces. Second, sunlight absorbed by our bodies produces huge amounts of vitamin D which has proven to increase our immune system along with other benefits to our cells and well being. I've been searching, but unable to find, any recent studies on how those living in "sunny states" would compare to those living in "cloudy states" in terms of COVID-19 deaths so I decided to to my own.
I used the source linked below to determine the top 10 "sunny states" which are AZ, NV, NM, WY, CA, UT, ID, GA, SD, FL (in descending order) based on the total average sunshine in the state. Using the same source, the top 10 most cloudy states are AK, NY, WA, OH, VT, OR, MI, WI, IN, NJ (also in descending order).
So here are the cumulative numbers as of noon today ...
Top 10 Sunny States:
Total COVID-19 Deaths = 5334
Total Population = 90.6 million
Total COVID-19 Deaths per million = 59
Top 10 Cloudy States:
Total COVID-19 Deaths = 38,528
Total Population = 75.8 million
Total COVID-19 Deaths per million = 508.6
As you can see from these cumulative totals, there have been approximately 8.6 times as many deaths per million in these cloudy states vs. the sunny states. Are there other factors? Sure, things like population density, use of public transportation, age of population, obesity rates, etc. would also have any impact on any population but you would think this is a large enough sample size (over 160 million people in these 20 states) that there must be some correlation between sunshine and avoiding the virus.
I can post or send anyone my spreadsheet with the numbers if interested. Below is my sunshine hours and COVID-19 deaths sources.
