Sleep Trackers: Are They Really Measuring What Matters?

Affectable Sleep challenges the efficacy of sleep trackers. The article argues that trackers overemphasize sleep duration and consistency, neglecting sleep quality and restorative function. For example, a tracker might give a low score even if someone gets a short but deeply restorative sleep. Trackers fail to interpret the physiological mechanisms behind sleep, offering only post-hoc analysis and no real-time optimization. The article advocates focusing on the physiological and neurological processes of sleep rather than mere data, and calls for a new approach that prioritizes sleep quality over quantity.
