The Claim

Solar radiation induces the release of nitric oxide in the skin, which results in systemic vasodilation and a reduction in arterial blood pressure.

How it works

2 studies reviewed

In plain English

When your skin is exposed to sunlight, it releases a substance that helps relax your blood vessels, which can lower your blood pressure.

Study: Ultraviolet Radiation-Induced Production of Nitric Oxide:A multi-cell and multi-donor analysis
Sunlight, especially its UV-A rays, causes skin cells to release a chemical called nitric oxide, which helps relax blood vessels and lower blood pressure. This study shows that happens in human skin cells, supporting the idea that sun exposure can be good for your heart.
Study: Photo-induced nitric oxide modulation in human skin: Impacts of geographic location and seasonality on health and disease.
When sunlight hits your skin, it releases a molecule called nitric oxide that helps relax your blood vessels, which can lower your blood pressure. This study shows that happens naturally in your body when you're in the sun.
