Study: Sunlight helps the skin to release a chemical that prevents the spread of Corona

A research study conducted by researchers at the University of Edinburgh in English |, revealed that ultraviolet rays resulting from exposure to the sun can release a chemical to the skin that prevents the spread of the Corona virus, as experts found that sunny places witnessed about a third less death due to the Corona virus and said that exposure to radiation Ultraviolet light causes the skin to release chemicals that prevent it from spreading.

According to a report by the British newspaper "Daily Mail", researchers from the University of Edinburgh compared Corona deaths with UV levels and confirmed that it is possible that there will be fewer Corona deaths due to the change of season.

Scientists indicated that exposure to sunlight, specifically UVA, caused the skin to release chemicals that prevent the spread of the virus, and researchers from the University of Edinburgh compared Corona deaths recorded with UV levels across 2474 counties in the United States between January and April of last year, and they found that people who live in the areas With the highest level of exposure to UVA rays, which constitutes 95% of the sun's ultraviolet light, they have a lower risk of death, and the chances of dying from corona have decreased by 32% for the counties with the highest daily average of UV rays.

The scientists explained that this matter was repeated in England and Italy with the same results, according to the results published in the British Journal of Dermatology, and experts said that the decrease could not be explained by higher levels of vitamin D, as the areas that were analyzed had insufficient levels of ultraviolet rays to produce what Enough vitamin in the body.

One explanation is that sunlight causes the skin to release nitric oxide, which may reduce the ability of the coronavirus to replicate.

The researchers took into account factors known to be associated with increased exposure to the virus and risk of death, such as age, race, socioeconomic status, population density, air pollution, temperature and infection levels in local areas.

Dr. Richard Wheeler, from the University of Edinburgh, said: "There is still a lot we do not understand about Covid 19, which has led to many deaths around the world. These early findings open up exposure to sunlight as a way to reduce the risk of death."

Previous research showed that increased exposure to sunlight is also linked to improved cardiovascular health, with lower blood pressure and reduced heart attacks.
