Episode notes
Circadian And Homeostatic Drives Govern Sleep
- Two processes control sleep: circadian (C) and homeostatic (S), involving melatonin/cortisol and adenosine respectively.
- Multiple neurotransmitters provide sleep and wake signals; misalignment causes disorders like narcolepsy and jet lag issues.
Manage Jet Lag With Light And Temperature Strategies
- Manage travel by manipulating light and body temperature because circadian rhythms can't instantly adapt to large time-zone shifts.
- No magic pill exists; use progressive strategies to manage jet lag rather than expect instant reset.
Diet, Tryptophan And Brain Glucose Link To Sleep
- Nutrition interacts with sleep via neurotransmitter precursors and brain glucose metabolism; study heterogeneity makes findings mixed.
- Early evidence: carbs, tryptophan, and overall diet quality relate to sleep, but protocols vary widely.
