New SAD Treatment – Shining Light Into The Brain Through The Ears
“The effectiveness and exact mechanism of this light-treatment was not fully understood until now, until researchers from Oulu, Finland, found that the central role was not played by the retina. Instead the light acts on light-sensitive proteins on the brain’s surface. Special earphones were designed that shine a beam of light through the ear canal to a light-sensitive area in the brain, this being an efficient alternative to light therapy.”
Comments: We have looked into the role of light in keeping SAD at bay before. In this article they explore whether it needs to be accessed through the eyes or whether there are other mechanisms that allow it to act.
