Covid-19.Experts say UVA rays cause the skin to release a chemical that alleviates symptoms.A global study found in sunny areas, Covid mortality rates fell.Dr Richard Weller of the University of Edinburgh, said: “There is still so much we don’t understand about Covid-19.
These early results open up sunlight exposure as one way of potentially reducing the risk of death.”Prof Chris Dibben added: “The relationship between Covid-19 mortality, season and latitude has been quite striking.” He said the research offered “an alternative explanation” for the sun pattern.The scientists believe sunlight exposure helped because it can cause the skin to release nitric oxide – which has reduced the virus’ ability to replicate in lab tests.Now light.
