Episode notes
Fix Sleep By Changing The Day
- Do focus on daytime behaviours, not elaborate bedtime rituals, to improve sleep.
- Stephanie: you can't fix the night with the night; fix it 15–20 hours earlier via your day.
Trackers Can Amplify Anxiety
- Sleep trackers produce data that humans overinterpret and which can increase anxiety.
- Stephanie suggests trackers should show trends, not nightly percentages, because nightly variation is normal.
Belief Shapes Sleep Performance
- Belief about sleep outcomes can change real performance; being told you slept badly harms function.
- Stephanie notes perception alone can make you perform as though you truly had poor sleep.
