Matt explores the frustrating reality of non-restorative sleep, explaining why up to a third of adults get a full night's rest but wake up exhausted. Using a relatable example, Matt shows how this hidden epidemic is often dismissed by normal sleep studies, despite being a clinical condition linked to anxiety, depression, and cardiovascular issues. He highlights how medicine is just starting to take this seriously.

Delving into brain research, Matt explains how disrupted deep sleep, sleep inertia, and social jetlag cause this daytime fog. Crucially, he proposes a paradigm shift: treating non-restorative sleep as a daytime wakefulness disorder rather than a nighttime one. By focusing on daytime alertness instead of just hours in bed, Matt offers a radical new framework for understanding persistent exhaustion and evolving sleep medicine.
