Lead study author Rami Burstein, PhD, vice chair of research in the anesthesia department at Beth Israel Deaconess Medical Center in Boston, and colleagues exposed patients to four different light colors (blue, green, amber and red) and asked patients to report any changes in migraine pain.
Here are four points:
1. Nearly 80 percent of patients reported their headache intensified when exposed to all the colors but green.
2. The researchers found green light exposure reduced migraine pain by 20 percent.
3. Dr. Burstein is developing an affordable light bulb that emits narrow band wavelength green light at low intensity, as well as sunglasses that block all but the narrow band wavelength green light.
4. In a 2011 study, Dr. Burstein and colleagues discovered blue light hurts blind migraine patients.
