The relationship between covid-19 and solar radiation has been gathered slowly through the pandemic. #COVID #COV1D #CovidIsNotOver

One of the first and perhaps most controversial findings was the protective effects of vitamin D, a vitamin synthesized by solar radiation. #COVID #COV1D #CovidIsNotOver

Also, melatonin treatment has been used for a faster recovery rate as well as a supplement for some of the symptoms of long covid. #COVID #COV1D #CovidIsNotOver

Solar radiation, along with temperature and feeding habits, is one of the environmental signals used to synchronize the circadian rhythm. Among other functions, the circadian rhythm also regulates the immune system. #COVID #COV1D #CovidIsNotOver

If any of the signals are used to synchronize the circadian rhythm it will generate a slight immunodeficiency over a wide population. This will generate an opportunity for a pathogen to propagate. #COVID #COV1D #CovidIsNotOver

Agreement between solar radiation and temperature can be evaluated at specific locations for large periods, showing a large disagreement during periods of large pandemic outbreaks such as the Russian and Spanish flu. #COVID #COV1D #CovidIsNotOver
