Across the year, daylight in Reno ranges from about 9h 12m in December to 14h 48m in June — a 5h 35m swing that shapes sleep, mood and training rhythms. At about 4,500 ft, thinner air also makes hydration and gradual training progressions more important. From roughly December through February, the sun sits too low for much vitamin D production.

Low-UVB “vitamin D winter”
At about 39.5°N, Reno sees a 5h 35m 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.
