Sunlight, UVA and nitric oxide. Another answer to covid?
Sunlight is indeed another answer to profoundly reducing the risk of Covid. By Marc Sorenson, EdD.
Sunlight is associated, with lower illness and death from the Covid-19 virus.
So says new research from the British Journal of Dermatology. I opine that this research is of epochal importance, and it is something I postulated a year ago. At that time, certain people mocked and belittled me. It seems like the “experts” of the world had a laser focus on producing a vaccine. Thus, they denigrated anything or anyone who did not follow their dictatorial rules. Consequently, I was gratified when this research appeared.
First of all, for the purposes of the Journal research into sunlight, the investigators assessed deaths from covid-19 at the county level across the USA. They then replicated the measurements in England and Italy. The researchers then measured the amount of sunlight in each county in Kilojoules, a unit of heat equal to .239 calories.
Furthermore, after measuring the sunlight and death from Covid-19, they adjusted their data for demographic, socioeconomic and environmental variables.
This part of the sunlight research is especially relevant:
“Only areas where UVB was too low to be inducing significant cutaneous vitamin D3 synthesis were modelled.” This took vitamin D out of the equation.
UVB light stimulates vitamin D production when it makes contact with the skin. Therefore, ensuring no vitamin D production (by eliminating UVB light), they eliminated a potential misconception. There was no way vitamin D could be the mechanism of action to decrease Covid-19. Thus, one might say that this was was a pure sunlight study, and the idea to eliminate vitamin D was pure genius.
Too many people believe that if sunlight exposure has a positive effect, the mechanism must be through vitamin D. This research corrects that theory.
So what is the mechanism, if it is not vitamin D? The answer is nitric oxide (NO). Sunlight exposure also produces NO in the skin. Yet, NO occurs in skin after exposure to UVA rays, not the vitamin D-producing UVB. In addition, NO has the ability to stop the replication of the Covid virus. One of the beauties of this system is that UVA rays and NO are available at any season when the sun is shining. This indicates that this healing action of sunlight is also available year-around.
The mortality risk ratio (death risk ratio) due to Covid-19, over the three countries, estimated a decline of 32% for each increase in 100 kilojoules per meter2. Thus, as sunlight intensity increased, death from Covid-19 decreased concomitantly. It seems like a great idea to increase exposure to non-burning sunlight among all areas where Covid-19 exists.
Certainly, the lockdown was a great detriment to human health.
