Can blue light reduce the blood pressure?

Exposure to blue light may help to fight hypertension, according to a recent study. High BP, or hypertension, is widespread in many countries. Hypertension is also a reason for many conditions like stroke, kidney disease, attacks, etc. For these reasons, hypertension should be maintained.

Now a day’s doctors are prescribing the hypertensive patients with ACE inhibitors, Calcium channel blockers. These are effective but also have side effects. To maintain a normal blood pressure one should maintain a proper lifestyle, diet, exercise, control stress levels.

According to the studies, exposure to sunlight influences hypertension. That is why BP is lower during summer months on an average. Some studies demonstrated that high levels of exposure to sunlight reduce the risk of dying from a cardiovascular disease.

As sunlight hits our skin, it drives a substance response that produces vitamin D, which plays a scope of basic jobs in the body. UV light likewise influences nitric oxide (NO) levels, and NO is a vital flagging particle in people and for all intents and purposes every single other living being. The inward covering of veins called the endothelium discharges NO. This makes the smooth muscles around the veins unwind, along these lines bringing down pulse. At the point when daylight hits the skin, mixes, for example, nitrites separate to deliver NO, which at that point diffuses into the more profound tissues and, at long last, enters the veins. The cooperation between daylight, NO, and the smooth muscles of the veins may clarify why daylight has a hypertension-limiting impact.

Every member visited the testing office twice, with multi-week between sessions. Amid one visit, they were presented to 30 minutes of entire body blue light. At the other, they got 30 minutes of "control light."

In particular, the researchers searched for changes in circulatory strain. They likewise evaluated different parameters, including pulse, bloodstream in the lower arm, flowing dimensions of NO, and beat wave speed, a proportion of how solid the conduits are.  Individuals from the group took estimations previously, amid, and after the light introduction. They found that 30 minutes of entire body blue light essentially brought down systolic pulse the weight in veins as the heart shrinks by 8 mm of mercury.

 Alternate parameters additionally enhanced fundamentally under blue light, including beat wave speed. Obviously, serum NO dimensions likewise expanded. The creators finish up our present examination exhibits out of the blue that entire body blue light introduction at dosages that are practically identical to day by day daylight presentation diminishes systolic pulse in youthful, solid male volunteers.

Albeit blue light treatment would never supplant changes in eating regimen and way of life, it might give extra advantages to specific individuals. This would be especially useful to those whose circulatory strain isn't effortlessly controlled by a drug, for example, more seasoned individuals.
