Episode notes
Supernormal Stimuli Hijack Dopamine
- Supernormal stimuli are digitally based and flood the brain with dopamine, hooking you into repeated use.
- Trish Leigh warns these stimuli drive an insatiable motivation for more, degrading natural rewards.
Screens Push Brain Into 'Wired‑But‑Tired'
- Screens flicker at about 60 Hz while calm focus resonates near 10 Hz, shifting brain frequency upward.
- This produces simultaneous fast and slow waves that feel 'wired but tired' and impair focus and mood.
Screen Dysregulation Erodes Self‑Awareness
- When brains enter wired, tired, or neutral states, self‑awareness drops and people miss the link between behavior and feeling.
- Trish Leigh explains this reduced self‑awareness makes screen harm sneaky and slow to recognize.
