The University of Edinburgh, reports "News Mail.RU", found out: in regions with a lot of sunlight, fewer people die from the coronavirus. The positive effect was associated with a certain type of UV radiation. As part of the study, scientists recorded deaths due to complications of COVID-19 in the United States from January to April 2020. UV levels were also recorded over the same period.

It turned out that people living in areas with the highest exposure to ultraviolet A (UVA), which accounts for 95% of the sun's UV radiation, had a lower risk of dying from COVID-19 compared to people living in areas with lower UVA levels. Similar results were obtained when analyzing statistics from Britain and Italy.

According to scientists, the revealed pattern cannot be explained by a higher level of vitamin D in the body - this vitamin is produced under the influence of UV-B radiation (UVB). Another theory is that sunlight causes the skin to release nitric oxide, which weakens the virus's ability to replicate.
