Sunlight may lower your blood pressure

NBC News reports:

Here’s why sunbathing feels so good: It may lower your blood pressure, British researchers reported Friday.

Just 20 minutes of ultraviolet A (UVA) sunlight lowered blood pressure by a small but significant amount in 24 volunteers, they report in the Journal of Investigative Dermatology. Further checks suggest the sun does this by increasing levels of nitric oxide, a chemical linked to blood flow.
