In this brief YouTube short, Nyree Penn, MHSc., CAA, challenges the prevailing focus on sleep advice that emphasizes bedtime routines, supplements, and wearable gadgets. She points out that while wearable devices display sleep data, they do not reliably differentiate between REM and non‑REM sleep. Penn questions the practical value of the information provided by these trackers, asking what users are supposed to do with the data and how they can actually address or resolve sleep problems based on such uncertain metrics.
