Green Light Helps to Ease Headaches

A new research conducted by the University of Arizona Health Sciences found that people who suffer from migraine may benefit from green light therapy.

During the study, patients were exposed to white light for one to two hours a day for 10 weeks. After a two-week break, they were exposed to green light for 10 weeks.

In the trial, green light is regarded as a drug by the researchers and they addressed how the right intensity, the right frequency, the right exposure time and the right exposure methods are all critical to the patients.
