Low-UVB “vitamin D winter”
At about 61.4°N, Alaska sees a 14h 3m swing in day length between the solstices. Low winter sun means little or no vitamin D production from sunlight for about half the year. That's roughly October through March. Bright morning light helps anchor your body clock, and a simple blood test shows whether your vitamin D is where it should be.
