As scientists have found out, blue light can stabilize high blood pressure: there is no need to take any medications. The risk of developing side effects with this unique treatment is practically zero.
Specialists from Great Britain and Germany have carried out joint work, during which they have discovered a new method of treating hypertension – safe and accessible. This method can become an excellent alternative to many drugs.
High blood pressure, or hypertension, is one of the most pressing medical problems, especially in economically developed countries. According to statistics provided by the American Center for Disease Control and Prevention, the negative consequences of high blood pressure lead to the death of about 1,000 residents of the country every day. Hypertension often becomes the "culprit" of heart attacks, strokes, renal failure, senile dementia, etc.
Today, the main medications prescribed for high blood pressure are diuretics, calcium channel blockers, and angiotensin-converting enzyme inhibitors. The use of various medications can prevent many complications and prevent the patient's death, but there is one drawback: absolutely all such medications have many side effects. In addition, it is necessary to take into account the fact that most patients are forced to take such medications almost until the end of their lives.
Is there a solution to this problem? Scientists from the German Heine University and the British University of Surrey have presented a new, unconventional method for stabilizing blood pressure. Research has shown that solar radiation has a significant effect on people suffering from hypertension. Thus, blood pressure readings are usually more stable in the summer, and the abundance of sunny days affects the reduction of mortality from hypertension.
Many people know that ultraviolet radiation has a damaging effect on the skin, leading to accelerated cellular aging. It has long been proven that direct sunlight can provoke the development of tumors - in particular, melanoma.
However, we must not forget that sunlight gives impetus to the launch of vital chemical processes – in particular, the biological synthesis of vitamin D. In addition, the rays affect the regulation of vascular tone. Of course, scientists did not intend to use potentially carcinogenic radiation for treatment. However, they seriously thought about an alternative.
The ideal solution was soon found: the therapeutic effect was provided by visible blue rays with a wavelength of 420 to 453 nm. Such radiation is capable of activating the biological synthesis of nitric oxide without damaging cellular structures, and without exhibiting mutagenic or carcinogenic properties.
As studies have shown, just half an hour of exposure to blue light can lower systolic pressure by about 8 mm Hg. Moreover, this reduction is gentle and safe.
Of course, we shouldn't give up on the pills yet, because we've only been presented with preliminary test results. But there's still hope that the hypertension problem will be solved soon. [ 1 ]
