Effect of blue light on human body

The latest research shows that blue light may be particularly suitable for treating depression. Blue light is emitted by glasses, panels and other devices used to treat health problems such as sleep disorder, jet lag, seasonal affective disorder and PMS. But blue light can't be stimulated only by vision; Short wave can penetrate the skin-this is the method of blue light to treat neonatal jaundice (the baby's liver can't remove bilirubin, a by-product of normal hemolysis). Bilirubin accumulates in the blood and enters the body tissues, making eyes and skin yellow. Blue light penetrates the skin and converts bilirubin into a form that is soluble in blood and excreted with urine. Bilirubin in blood continues to accumulate in tissues, and the conversion of bilirubin by blue light will continue until most or all bilirubin is converted and excreted.
