Can Exposure to the Sun Affect Your Blood Pressure?

Posted on by

High blood pressure (or hypertension) is a common, yet potentially very serious health condition that can lead to heart disease or stroke. To combat hypertension, doctors usually recommend that their patients follow a healthy, low salt diet and exercise regularly, but is there another simple thing that we all can do to lower our blood pressure?

Recent studies have indicated that spending more time outdoors in the sun can lower your lower pressure. What was found is that nitric oxide stored in the top layers of the skin reacts to sunlight and cause blood vessels to widen as the oxide moves into the bloodstream. That, in turn, lowers blood pressure.  The research, which was conducted by British researchers at the University of Southampton, exposed individuals with blood pressure within normal range to ultra violet light.  After exposure, those in the study saw a modest decrease in blood pressure levels. Researchers believe that the drop will be even more significant in individuals with elevated blood pressure.

Additional studies have concluded that people with higher levels of Vitamin D ( a vitamin that is commonly linked to sun exposure), experienced lower blood pressure levels and were at lower risk of developing hypertension. In fact, according to one recent study, for every 10 percent increase in vitamin D levels, there was an 8 percent decrease in the risk of developing hypertension.

Lastly, blood pressure levels tend to fluctuate seasonally, with levels typically being at their highest during the winter months. There are many potential factors for this, including  changing weather patterns and increased weight gain during the winter, but could more sun exposure be a factor in lower blood pressure during summer months?

This information does not mean that those looking to lower their blood pressure should rely on sun exposure as their only form of treatment against hypertension, nor should individuals ignore the potential dangers of prolonged, unprotected exposure to the. This research merely suggests that, if done responsibly, exposure to the sun can have a positive effect on your blood pressure levels.

If you have hypertension, speak with your physician about how increased sun exposure may benefit your condition. If you do not have a doctor, please call 718-670-5486.

The Sun is Nothing to Sneeze at…or is it?

Have you ever stepped out of a dark movie theatre into the bright sunlight and felt the urge to sneeze? If so, you probably have a harmless and not all that uncommon disorder known as Photic Sneeze Reflex.

This condition is characterized by the uncontrollable impulse to sneeze provoked by a transition from dark environment to an intensely bright surrounding, usually sunlight.
Also referred to as the “Achoo Syndrome”, this involuntary reflex is a genetic trait that affects both males and females alike. It is estimated that anywhere from 15 – 35 percent of the population has this disorder.

Those who have the photic sneeze reflex usually sneeze two to three times (although in rare case, some can sneeze up to 40 times) when transitioning from dark to bright environments, and while there are no associated health risks, there are concerns that this condition can be dangerous for people in certain professions, such as airline pilots.

While no one really knows why this reflex occurs, there are multiple theories that suggest that certain optic nerves are too close to other nerves that may trigger a reaction in the brain of photic sneezers or simply that those with this condition have a more sensitive visual system.

Regardless of the reason, the next time you exit a movie theatre on a bright sunny day, take notice of how many people exiting start sneezing, you might be surprised.
