Sleep As The Bedrock Of Health
- Sleep is the bedrock of health that supports cognition, cardiovascular and metabolic function, recovery, and exercise performance.
- Shelby Harris emphasizes timing, quality, and consistency alongside duration to make sleep the foundation for other health behaviors.
Prioritize Timing Consistency Over Perfection
- Aim for consistent sleep timing within about 30–60 minutes and target roughly 7–9 hours per night for most adults.
- Use daytime cues: regular wake time, daylight exposure, movement, limit caffeine 8–12 hours before bed, avoid alcohol within 3 hours, and keep the room cool and dark.
Blue Light Is Less Villainous Than You Think
- Blue light's direct effect on melatonin is modest; classic studies found only about an 11-minute delay from evening blue light exposure.
- The bigger problem is screen content and timing that keeps you awake, so distance/brightness and calming content matter.
