According to a recent study, exposure to blue light reduces blood pressure, which also reduces the risk of heart disease. For the study, the participants’ entire body was exposed to blue light at about 450 nanometers for 30 minutes, which is equivalent to the sunlight they receive during the day. During this time the effects of both light irradiation were assessed and blood pressure, arterial stiffness, blood vessel dilation and blood plasma levels of the participants were measured. Unlike ultraviolet rays, blue rays are not carcinogenic. According to researchers at the University of Surrey, UK and Heinrich Heiney University of Dusseldorf, Germany, exposure to full-body blue light reduced participants’ systolic (high) blood pressure by approximately 8 mmHg, with no such effect on normal illumination.

exposure to blue light reduces blood pressure, which also reduces the risk of heart disease.
Our heart is a kind of muscle, which pumps blood around the body and sends blood to our entire body. Our heart pumps oxygen rich blood around the body to supply our muscles and cells, which is the main cause of blood pressure. When you make your blood pressure check, it takes into account how much blood is passing through your blood vessels and the amount of blood resistance when the heart is pumped. Reduction in blood pressure with blue light is similar to the way blood pressure is reduced through medicines. When your blood pressure reaches an unhealthy level, it causes high blood pressure or high blood pressure.
