Blue light may help reduce blood pressure and the risk of cardiovascular disease

In a recent study published in the international journal European Journal of Prevention Cardiology, scientists from institutions such as the University of Surrey found that exposure to blue light may lower the body's blood pressure and reduce an individual's risk of cardiovascular disease.In the
article, the researchers exposed participants to about 450 nanometer wavelengths of blue light for 30 minutes, a dose equivalent to daily sunlight exposure, while exposing another group of participants to controlled light; In contrast, it did not have carcinogenic properties, and in order to assess the effect of blue light on the body, the researchers measured the participants' blood pressure, arterial hardness, vascular expansion and levels of nitric oxide in the plasma before, during and two hours after the experiment.
researchers found that exposure to blue light significantly reduced the body's systolic blood pressure by almost 8mmHg, while controlled light had little effect on the participants, and that the effect of lower blood pressure in the body induced by blue light was similar to that of clinical patients taking antihytrollers. In addition to lowering blood pressure, the researchers also found that blue light can help improve risk markers for other cardiovascular diseases in the body, such as lower arterial stiffness and increased vascular relaxation, suggesting that blue light may be used in the future to prevent cardiovascular disease, which kills more than 150,000 people in the UK each year.
the researchers say exposure to blue light increases the body's levels of nitric oxide, an important signaling molecule that protects the body's cardiovascular health, and the researchers believe that blue light penetrates the bloodstream from the skin, soothing blood vessels and increasing blood flow to lower the body's blood pressure. 'Blue light may provide us with an innovative way to precisely control the body's blood pressure without using drugs, and wearable blue light sources can make it possible for the body to remain exposed to daylight, especially for patients who rely on drugs to control their blood pressure, such as some older people,' said Professor Iss.
