According to multiple sources, green light is the color of LED light that helps with headaches and migraines. Exposure to a narrow band of green light may reduce light sensitivity and headache severity. Green light can even reduce pain by about 20% and worsens migraines significantly less than all other colors of light. Green light of a particular wavelength can minimize the intensity of migraines and reduce the likelihood of an intense headache occurring in the first place. Green light does not activate the retinal pathway, making it less likely to cause headaches. Other colors of light, such as blue, red, white, and amber, may cause headaches or trigger migraines in some people. It is important to consult a physician before self-implementing green light therapy, especially for severe or chronic pains.
