Here comes the sun to lower your blood pressure.

From the 14 January 2014 ScienceDaily article

Exposing skin to sunlight may help to reduce blood pressure and thus cut the risk of heart attack and stroke, a study published in theJournal of Investigative Dermatology suggests.

Research carried out at the Universities of Southampton and Edinburgh shows that sunlight alters levels of the small messenger molecule, nitric oxide (NO) in the skin and blood, reducing blood pressure.

Martin Feelisch, Professor of Experimental Medicine and Integrative Biology at the University of Southampton, comments: “NO along with its breakdown products, known to be abundant in skin, is involved in the regulation of blood pressure. When exposed to sunlight, small amounts of NO are transferred from the skin to the circulation, lowering blood vessel tone; as blood pressure drops, so does the risk of heart attack and stroke.”

From the March 9 Science Daily item

ScienceDaily (Mar. 9, 2011) — A study from the Swedish medical university Karolinska Institutet has shown that the body’s ability to break down medicines may be closely related to exposure to sunlight, and thus may vary with the seasons. The findings offer a completely new model to explain individual differences in the effects of drugs, and how the surroundings can influence the body’s ability to deal with toxins.

The study will be published in the scientific journal Drug Metabolism & Disposition and is based on nearly 70,000 analyses from patients who have undergone regular monitoring of the levels of drugs in their blood.
