Research Finds Blue Light Exposure Helps to Decrease Blood Pressure

In the study, published in the European Journal of Preventative Cardiology, participants were exposed to 30 minutes of whole-body blue light at approximately 450 nanometres, the wavelength similar to daily sunlight – followed by exposure to a control light on a different day. To assess the impact, participants’ blood pressure, artery stiffness, blood vessel dilation and blood plasma levels of nitric oxide stores were measured before, during, and up to two hours after irradiation with both lights. With the experiment, researchers discovered that exposure to whole-body blue light significantly reduced the systolic blood pressure of participants by almost 8 mmHg, compared to the control light which had no impact. According to the study, the reduction of blood pressure from blue light is similar to what is seen in clinical trials with blood pressure lowering drugs. https://www.ledinside.com/
