Sunlight Might Be Good for Your Blood Pressure
Jan-23-2014

Sunlight is known to lower blood pressure, but now a team of British researchers has figured out why.

What they found is that nitric oxide stored in the top layers of the skin reacts to sunlight and causes blood vessels to widen as the oxide moves into the bloodstream. That, in turn, lowers blood pressure.

"This is an unexpected finding, in that the skin has not been considered to be involved in blood pressure regulation," said lead researcher Martin Feelisch, a professor of experimental medicine and integrative biology at the University of Southampton.

Feelisch said he thinks -- if this finding is confirmed in further research -- exposure to ultraviolet light might help reduce the risk for heart disease. "That's where it becomes interesting," he said.
