So how can excess sunlight curb COVID-19?

According to Weller’s research team, one possible explanation is that sun exposure causes the skin to release a chemical called nitric oxide. Some laboratory studies have found that nitric oxide may reduce the ability of the new coronavirus to replicate and spread. The author of the study is planning to do more research on the theory.

The team’s previous research found that increased sunlight exposure is related to better sunlight exposure. Heart health, Lower blood pressure And less heart disease. heart disease They believe that this is a known risk factor for death from COVID-19, so past research can also help explain the new findings.

Two COVID-19 experts in the United States agreed that these findings are interesting but worthy of further study.

Dr. Robert Gratt, an emergency medicine physician at Lenox Hill Hospital in New York City, emphasized: “This study did not establish a causal relationship. At best, it can only represent an association.” He did not feel that vitamin D had no health benefits. Surprised.

Glatter said: “Although there is evidence that vitamin D may have a beneficial effect on immune function, there is no specific antiviral effect.” “In fact, a randomization of moderate to severe COVID-19 patients receiving high doses of vitamin D Controlled studies show no benefit.”

Dr. Amesh Adalja, a senior scholar at the Johns Hopkins University Health and Safety Center in Baltimore, is a virus expert. He said that this study raises interesting questions, but the nitric oxide hypothesis needs more research.

“Put these links together to show how this happens, I think this is where you want to see this research direction, the purpose is to show that sunlight also has the benefit of not relying on vitamin D,” Adalja said.
