Sunscreen Might Help Maintain Health of the Blood Vessels
A recent study from Pennsylvania State University suggests that sunscreen may not only protect from sunburn and skin cancer but also can help maintain the health of the blood vessels.
For the study, the researchers recruited 13 healthy participants all of whom had light-to-medium skin tone. One arm of each participant was exposed to UVR, and the other arm served for the control purpose. The UVR exposure equaled to approximately one hour of staying outside on a sunny day.
The analysis showed that in the areas, exposed to UVR, nitric oxide (NO) was prevented from triggering the relaxation of the muscles in blood vessels reducing the ability of the body to cool itself down. At the same time, areas with the sunscreen didn’t show any reduction of NO-associated vasodilation.
