Low-UVB “vitamin D winter”

At about 30.3°N, Jacksonville sees a 3h 55m swing in day length between the solstices. UVB is weakest in midwinter, but midday sun can still support vitamin D production most of the year. That's roughly late December to January. Bright morning light helps anchor your body clock, and a simple blood test shows whether your vitamin D is where it should be.
