So why blue lights actually help?

• benrapscallion 11y ago
  The retina contains a blue light sensitive photo pigment called melanopsin, in specialized retinal ganglion cells. These melanopsin RGCs help integrate environmental light into multiple systems including those that control mood. Blue light this has beneficial effects in many neuropsychiatric disorders such as seasonal affective disorder.

      Blue light can also strongly disrupt sleep cycles, so watch out.
