Light-sensitive individuals (15% worldwide) and those whose headaches are light-sensitive do better in green light.
A complex study exposing subjects to lights of varying colors while measuring electrical signals at the eye and the brain levels showed color matters!
Red and blue lights generated the most signals, while green light produced the least. The less signals bombarding the brain the better, hence the discovery that migraine sufferers experience some improvement when exposed to green light.*
Study conducted at Beth Israel Deaconess Medical Center (BIDMC) and published in the journal Brain.
