Yep, sunlight helps the immune system, which is a major reason people get more sick in the winter than the summer.
UV light kills many viruses. Also some viruses thrive in low temperature and low humidity. The sars cov 2 virus starts to melt at room temperature. Its not just higher levels of vit D. There are lots of factors .
Yes, there are lots of factors, but I think the impact of Vitamin D is underestimated. Regardless of the season, temperatures indoors stay pretty much the same. Humidity increases during the summer a little bit. So I wouldn't expect a cold/flu virus to be less likely to spread indoors during the summer vs winter.
Therefore, I think people getting sicker during the winter is the primary factor for virus transmission. Which would occur from depressed immune systems from lack of Vitamin D.
I read an article which stated that viruses on dried up particles of snot or dust or something are more airborne in dry low humidity conditions. They made it sound much more technical. I was reasearching what caused seasonal trends of flu in general.
I think hours of UV light / day is probably part of the equation since NY gets a larger seasonal trend than Miami in summer but not more light intensity.
Different viruses seem to have much different preferences for light and heat and humidity.
I am aware of the study that linked higher Vit D levels to lower rate of covid positive tests, but I would be careful about drawing conclusions there.
Vitamin D seems to work well as a “natural steroid” against severe covid. What is the proposed mechanism for preventing infection? Does it improve innate immune function as well?
Viruses are a result of a toxic terrain. Covid does not exist.
Viruses are the result of evolution, which is also real. Sars cov 2 is real and kills older people at high rates. Also magic is fake and the earth is round.
“Toxic” terrain. Oh okay. Some terrain is apparently just “toxic”, any particular reason? Evil fairies? Chem trails?
