Whole body blue light exposure significantly reduces systolic blood pressure. I study.Don't store avocado like this: it's dangerous
A new study states that exposure to blue light is an effective and side-effect free treatment for hypertension, simultaneously reducing the risk of developing cardiovascular disease.
Reduce hypertension in a completely natural way with the help of only a blue light, also able to protect the health of the heart with an effectiveness comparable to that of drugs.
This was revealed by a study published in the European Journal of Preventative Cardiology conducted at the University of Surrey and Heinrich Heine University in Duesseldorf.
Participants in the experiment were exposed to 30 minutes of whole-body blue light at approximately 450 nanometers - a dose comparable to daily sunlight - followed by exposure to a control light on a different day.
Visible blue light, unlike ultraviolet (UV) light, is not carcinogenic. To assess the impact, participants' blood pressure, stiffness of the arteries, dilation of blood vessels, and plasma levels of nitric oxide deposits were measured before, during and up to two hours after irradiation with both lights. .
The researchers found that whole-body blue light exposure significantly reduced systolic blood pressure by nearly 8 mmHg, compared to control light which had no impact.
What's even more remarkable is that the reduction in blood pressure from blue light is similar to what is seen in clinical trials with drugs which perform this function.
In addition to the blood pressure lowering effects, it was also found that exposure to blue light improved other cardiovascular risk indicators, including the reduction of arterial stiffness and increased relaxation of blood vessels, and which is capable of increasing levels of nitric oxide, an important signaling molecule that protects the cardiovascular system. Blue light is believed to release it from the skin into the bloodstream where it relaxes blood vessels, increasing blood flow and decreasing blood pressure.
“Exposure to blue light provides an innovative method to precisely control blood pressure without medicine. Wearable sources of blue light could make this therapy continuous and practical for the patient. This could be of particular help to those who cannot manage their blood pressure well with medication, for example the elderly, ”concludes Christian Heiss, Professor of Cardiovascular Medicine at the University of Surrey.
Fun Fact: This isn't the first time blue light has been revealed to have a positive impact on people's health. Since blue lighting has been linked to mood enhancement, dozens of Japanese train stations have for example installed blue lights as a means of reducing their suicide rates. Over the course of 10 years, the suicide rate at stations plummeted by 84%. Interesting, isn't it?
