Chapter 1: Protocols for Sleep
Sleep as Foundation
- Sleep shapes mental health, physical health, and performance.
- Aim to sleep well 90-95% of nights.
- Chronic sleep deprivation linked to heart disease, stroke, diabetes.
- Chronotype is genetic; sleep need is 7-8 hours for most adults.
Morning Light Protocol
- View sunlight within 30-60 minutes of waking, 5-10 minutes.
- Light must be unfiltered by glass, sunglasses, or hat brim.
- Sets the suprachiasmatic nucleus, the master circadian clock.
- Melanopsin-containing ipRGCs detect low solar angle sunlight.
Light and Energy
- Morning light shuts off residual melatonin via SCN and pineal gland.
- Adenosine falls, preventing circadian drift.
- Morning cortisol rise amplified by up to 50%, peaking after waking.
- Late afternoon light delays clock and offsets morning light.
Night Light and Chronotype
- Dim lights after sundown; use amber/red bulbs or blue-blocking glasses.
- Bright light at night raises cortisol, lowers dopamine, causes anxiety.
- Guard six hours before temperature minimum (about 2 hours before waking).
- Camping study: sunlight shifts sleep earlier, persisting after weekend.
Sleep Architecture and Health
- Sleep cycles ~90 minutes through N1, N2, N3, REM.
- N3 releases growth hormone and flushes brain waste.
- REM consolidates skills and unloads emotion.
- Each 1% drop in REM linked to 9% higher dementia risk.
Temperature and Napping
- Keep bedroom 65-68°F; warm extremities, leave hands/feet exposed.
- Raise room temperature 1-3°F in last hour before waking to lengthen REM.
- Naps: 20 minutes for energy boost, up to 90 to process emotion.
- Skip naps if struggling to fall asleep at night due to adenosine.
Supplements and Prescriptions
- Behavioral tools first; try supplements one at a time.
- Options: magnesium L-threonate/bisglycinate, apigenin, theanine, melatonin 0.5-1.5 mg.
- Take 30 minutes before bed; theanine pairs with caffeine.
- Prescription sleep aids are last resort; CBT has lasting efficacy.
