Winter: you are under artificial LED lighting for 16+ hours a day and the blue spike from those lights suppresses melatonin just as effectively as sunlight - even in complete outdoor darkness. For anyone dealing with mørketid, Sundown lenses from late afternoon, every evening through winter, is the most practical intervention available.
