Episode notes
INSIGHT

Skin as a Circadian Organ

  • Dermatology lacks circadian biology insight, viewing skin without its natural circadian clock.
  • This disconnect leads to flawed advice on sunscreen and sun avoidance despite skin's inherent rhythmicity.
INSIGHT

Circadian Control Prevents Cancer

  • Anti-cancer mechanisms like DNA repair and apoptosis are regulated by circadian rhythms.
  • Disrupted circadian rhythms impair these defenses, increasing skin cancer risk despite sun exposure levels.
ADVICE

Sun Exposure Timing Matters

  • Start sun exposure with morning red and infrared light to prepare skin before midday UV arrives.
  • Use morning sunlight to build resilience; avoid sunbathing in intense midday UV without gradual adaptation.
