Low-UVB “vitamin D winter”

At about 35.9°N, Tennessee sees a 4h 53m 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.

FAQ

Tennessee wellness FAQs

Can I take a wellness genetic test in Tennessee?

Yes. At-home wellness genetic tests are ordered online and completed with a sample kit.

How can shift workers protect their sleep?

Keep a consistent sleep window, use blackout curtains and eye masks, time caffeine early in your shift and get bright light at the start of your “day.”

Can you get enough vitamin D from the sun in Tennessee?

Tennessee sits at about 35.9°N. Research suggests winter UVB is too weak for meaningful vitamin D production for roughly three months a year. That's roughly December through February. Skin tone, sunscreen, age and time outdoors also matter, so a blood test is the only way to know your level — ask your clinician before supplementing.

The bottom line

Staying healthy in Tennessee means planning for hot, humid summers and mild winters — heat-smart summer training, hydration with electrolytes and sleep consistency around late nights — on top of the fundamentals: consistent sleep, daily movement, strength training and a whole-food diet.
