ADVICE

Train Skin With Progressive Sun Sessions

  • Use progressive, short sun exposures to train your skin and intuition rather than overthinking vitamin D production.
  • Stop relying solely on apps or blood 25(OH)D tests and pay attention to skin warming, pinking, or itching as signals to go inside.

Blood Vitamin D Is An Incomplete Signal

  • Vitamin D blood levels are one blunt metabolite and miss the broader effects of sunlight on physiology.
  • Circadian alignment, blue light exposure, infections, and sleep all influence vitamin D status and sunlight benefits.
