In today’s blog, the Cheapest Life Insurance looks at the research carried out by the University of Edinburgh and University of Southampton, which shows that sunlight may reduce the risk of cardiovascular disease by lowering blood pressure.
The study may lead to a review on the advice that we are currently being given, regarding the benefits and risks sunbathing.
Although it is shown that overexposure from UV light could put you at risk from skin cancer you should not avoid the sun altogether, as you could also increase your risk of developing cardiovascular disease.
The research carried out by Edinburgh and Southampton University was done by examining nitric oxide that is found within the blood and skin. This molecule helps to support the regulation of blood pressure and once exposed to sunlight is able to dilate blood vessels in the body, as well as lower blood pressure significantly.
This study could be a break through, as if it was possible to lower blood pressure by simply sunbathing, the risk of having a heart attack or stroke, could also be lowered.
The research was conducted by analysing 24 volunteers as they were exposed to UV lights from tanning lamps, within two twenty minute sessions. Within one of these sessions, the volunteers were exposed to the ultraviolet light from the rays and the heat of the lamps, whereas in the other session, the ultraviolet rays were blocked and only the heat from the lamps were able to affect the skin.
Dr Feelisch, from the University of Southampton has said “These results are significant to the ongoing debate about potential health benefits of sunlight and the role of vitamin D in this process,” Dr Feelisch said in a press release.
“Avoiding excess sunlight exposure is critical to prevent skin cancer, but not being exposed to it at all, out of fear or as a result of a certain lifestyle, could increase the risk of cardiovascular disease.”
