Key Takeaways

  • Get bright light exposure within 30-60 minutes of waking for 10-15 minutes (sunlight preferred, SAD lamps as backup) to boost cortisol and anchor circadian rhythm
  • Consume caffeine in the morning (especially if over 60) to support cortisol production and circadian regulation
  • Exercise early in the day to shift circadian rhythm earlier – walking counts
  • Take cold showers in the morning to stimulate cortisol production
  • Prioritize sunrise/sunset sunlight for maximum red/infrared light benefits (skin anti-aging, blood sugar control) with minimal UV damage

Supplements & Protocols Mentioned

  • P7C3-A20 (experimental NAMPT activator for NAD recycling, not commercially available)

Notable Quotes

“The key to mitigating [aging-related circadian disruption] is to have high cortisol in the morning, so that your body would know that it’s daytime.”

Bottom Line

Optimize your first waking hour with bright light, movement, and caffeine to strengthen circadian rhythms – this is more impactful for longevity than diet or exercise timing alone.
