Episode notes
Late Sleeper Patient
- Dr. Hassan tweeted after seeing a young patient relieved to learn their late sleeping was normal.
- The patient's family pressured him to wake early, causing guilt, but his physiology favored later sleep.
Sleep 101
- Two factors control sleep: sleep homeostatic drive (brain waste buildup) and circadian rhythm (internal clock).
- Best sleep occurs when these two align, meaning your brain's garbage can is full when your brain clock says it's bedtime.
Unique Clocks
- Everyone has a unique circadian clock, and it's normal for it to vary like height or hair color.
- Society pressures everyone into the same sleep schedule, disadvantaging those with different clocks.
