Episode notes
Circadian Clock Controls Morningness
- Our daily rhythm is controlled by an internal clock slightly longer than 24 hours called the circadian clock.
- Genetics and environment both influence if a person is a morning or night type, including hormones melatonin and cortisol.

- Go to bed early to avoid "revenge sleep," where you stay up late and get woken by an alarm.
- Waking up naturally aligned with cortisol release helps you start the day fresh without relying on alarms.
