Research shows that when skin is exposed to sunlight, nitric oxide is released in blood vessels, resulting in lowered blood pressure.
A research team at Edinburgh University exposed volunteers to tanning lamps for 20 minutes and then in a separate session exposed those same volunteers to heat, but not UV light, for the same period. The findings were those volunteers exposed to UV light had a significant drop in blood pressure one hour after UV exposure. Exposure to heat did not show any effect on blood pressure. The research team concluded that the benefits of sunbathing outweigh the risks for heart disease and stroke, linked to blood pressure, that kills 80 times more people than skin cancer in the UK.
Dr. Richard Weller, dermatologist and lead researcher, said, according to BBC, “Our work also explains why dietary vitamin D supplements alone will not be able to compensate for lack of sunlight. We suspect that the benefits of heart health of sunlight will outweigh the risk of skin cancer. “ Dr. Weller also stated…”If this confirms sunlight reduces the death rate from all causes, we will need to reconsider our advice on sun exposure.”
The results of this research were presented at the world’s largest gathering of skin experts in Edinburgh, The International Investigative Dermatology conference. To view a video of Dr. Wellers preliminary findings, watch the video below.
