Your sunscreen may be contributing to your high blood pressure. How so? In a recent study conductd by leading dermatologists, it was found that UVA rays reacting upon the skin help to decrease blood pressure. This is possible because Nitric Oxide exists beneath the skin. Nitric Oxide is a molecule that does many things including relaxing narrowed blood vessels, thereby increasing oxygen and blood flood (Viagra makers understand this very well). With this in mind, one should question whether it’s in their best interest to block the skin’s UVA receptibility- especially if they have blood-flow issues. Read more.
