The results of an investigation into the effects of blue light on high blood pressure were recently published in the European Journal of Preventative Cardiology.
According to the Centers for Disease Control and Prevention (CDC), high blood pressure is a primary or contributing cause of almost 1,000 deaths every day in the U.S. Hypertension is also a risk factor for more serious conditions, such as heart attack, stroke, and kidney disease.
Blood pressure is, on average, lower during the summer months, and some research has linked high levels of long-term sunlight exposure to a reduced risk of dying from cardiovascular disease.
Recently, researchers from the University of Surrey in the United Kingdom and Heinrich Heine University Dusseldorf in Germany joined forces to investigate whether blue light without UV wavelengths has the potential to ease hypertension.
For the first time, researchers assessed whether blue light exposure could produce enough NO to significantly reduce high blood pressure.
