A new study links exposure to sunlight with a reduced risk of death from corona

Sunlight could explain the apparent variation in the numbers of corona deaths.

Data from countries badly affected by the "Covid-19" disease, such as Britain, Italy and the United States, indicate that sunny areas are "associated with fewer deaths from (Covid-19)," according to scientists at the University of Edinburgh.

The study, published in the British Journal of Dermatology, said that "high UV exposure is associated with a decrease in the specific mortality rate for (Covid-19)."

The team compared deaths related to "Covid-19" in the United States during the period from January to April 2020 with the levels of UV radiation in nearly 2,500 American provinces, before repeating the use of the same methodology in Britain and Italy.

The three countries recorded some of the highest numbers of deaths related to the pandemic in the world, both per capita and absolute, despite the significant decrease in deaths during the summer months.

Most of Asia and Africa experienced a relatively low per capita death rate throughout the pandemic.

"The relationship between the (Covid-19) mortality rate and the seasons ... was very amazing, and here we present an alternative explanation for this phenomenon," said the co-author of the research paper, Chris Deben.

The researchers stated that, taking into account the potential effect of vitamin D, which is widely cited as an inhibitor of "Covid-19" and called "the sunshine vitamin", since the human body produces more of it when the skin is exposed to sunlight.

The team said, "Exposure to sunlight may reduce deaths from (Covid-19) independently of vitamin D."

Other recent results have given weight to the theory that time spent outdoors reduces the likelihood of developing Covid-19 disease.
