Low-UVB “vitamin D winter”
At about 40.0°N, Columbus sees a 5h 41m swing in day length between the solstices. Research suggests winter UVB is too weak for meaningful vitamin D production for roughly three months a year. That's roughly December through February. Bright morning light helps anchor your body clock, and a simple blood test shows whether your vitamin D is where it should be.
