Episode notes
Sleep Pressure and Adenosine
- Adenosine, a chemical, builds up in the brain throughout the day, causing sleep pressure.
- Sleep clears out adenosine, typically taking about 8 hours to remove 16 hours' worth.
Regularity and Chronotype
- Maintain a regular sleep schedule, even on weekends, to regulate your circadian rhythm.
- Respect your chronotype (morning/evening person) and try to align your schedule accordingly.
Sleep Debt Repayment
- You cannot fully repay sleep debt by sleeping in on weekends.
- Weekend catch-up sleep only recovers about 50% of lost sleep, disrupting your weekday rhythm.
