Researchers have literally shed light on probable means of relieving migraine pain. Working with 69 migraine patients, they found that while headache pain was exacerbated by blue light, low-intensity green light of a narrow spectrum condensed light sensitivity. In some cases, it even reduced migraine pain by 20 per cent. While there’s need for more research on the matter, it could potentially aid 80 per cent of migraine patients that have to isolate themselves in darkness during attacks to reduce exacerbation by light sensitivity. The researchers hope that in future it can lead to the production of cost-effective narrow-band green light bulbs and sunglasses that only allow narrow-band green light through.
