Sun and Heart Health

This is a challenging TED video that all who are interested in “practicing safe sun” should watch.  “Our bodies get Vitamin D from the sun, but as dermatologist Richard Weller suggests, sunlight may confer another surprising benefit too. New research by his team in Edinborough shows that nitric oxide, a chemical transmitter stored in huge reserves in the skin, can be released by UV light, to great benefit for blood pressure and the cardiovascular system. What does it mean? Well, it might begin to explain why Scots get sick more than Australians.”  Perhaps, the slavish avoidance of ultraviolet light recommended by many dermatologists is not a panacea.
