⏱️ Key Takeaway: Foundational morning behaviors can dramatically impact alertness, focus, and overall daily performance
Foundational Behaviors for Daily Optimization
- Sleep and Non-Sleep Deep Rest:
- Sleep: Essential for regulating metabolism, immune system, and cognitive functions. Aim for good sleep 80% of the time.
- Non-Sleep Deep Rest: Helps in daily performance even when sleep isn’t perfect.
Circadian Rhythms and Light Exposure
- Circadian Clocks:
- Every cell has a 24-hour cycle; aligning these clocks is crucial for health.
- Morning Light Exposure:
- Get natural light in your eyes within an hour of waking to anchor the cortisol pulse, set temperature rhythms, alertness, and mood.
- Ideal is 5-10 minutes of outdoor light without sunglasses, even on cloudy days.
- Indoor lights are not sufficient; use LED light boxes if natural light isn’t available.
- Effects of Light:
- Light exposure triggers dopamine release, influencing motivation, mood, and even physical changes in skin and fur in animals (seasonal breeding).
- Light on skin increases testosterone and estrogen, potentially enhancing passion and drive.
Caffeine and Adenosine
- Adenosine Build-Up:
- Accumulates during wakefulness, promoting sleepiness through the parasympathetic nervous system.
- Caffeine: Blocks adenosine, enhancing alertness but can lead to an afternoon crash if consumed too early.
- Practical Advice:
- Delay caffeine intake by 60-90 minutes after waking to clear adenosine naturally.
- Exercise can also help clear adenosine, improving alertness.
Temperature and Body Rhythms
- Core Body Temperature:
- Waking up coincides with a rise in core body temperature, which triggers cortisol release.
- Temperature Minimum: Typically around 2-3 hours before waking, crucial for understanding sleep cycles.
- Temperature Regulation for Sleep:
- Keep rooms cool at night to facilitate sleep by lowering core temperature.
Cold Exposure
- Benefits of Cold Exposure:
- Increases core body temperature paradoxically, leading to a release of epinephrine and dopamine.
- Can mimic some effects of addictive substances in terms of dopamine release, potentially aiding in addiction recovery.
- Helps in creating a sense of summer within the body, enhancing mood and physical performance.
Conclusion
- Morning Routine:
- Bright light exposure, delaying caffeine, exercise, and possibly cold exposure can significantly enhance daily performance, mood, and health.
