The team found that the rate of increase in coronavirus infections decreased by 7% in the summer, and this result came after researchers studied virus infection rates in 173 countries to collect data.
According to scientists, the rate of increase in infections decreased by 7.4% in the northern hemisphere from January 2020 to June 2020, when ultraviolet radiation levels increased.
In contrast, the number increased by 7.4% from July to December, when UV levels there decreased.
The ozone layer blocks the ultraviolet rays emitted from the natural sunlight of wavelengths that are capable of killing viruses, and this means that ultraviolet rays cannot kill viruses directly, but it enhances virus resistance because the body makes “vitamin D” when exposed to sunlight, and this matter Necessary to confront the epidemic.
A study conducted in October of last year on 216 patients with Coronavirus in Spain showed that 82% of them lack “vitamin D”, according to the website “chosun“.
Also, Michael Holick of Boston University published a study last September, which showed that people with a vitamin D deficiency were 50% more likely to contract the Coronavirus.
And last June, an American study said that summer sunlight at noon can stop the effectiveness of up to 90 percent of the virus in areas with high temperatures, within 34 minutes.
The study, the results of which were published in the Journal of Photochemistry and Photobiology, indicated that ultraviolet rays in the middle of the day could disrupt 90% of coronaviruses.
