In this YouTube short, Nyree Penn, MHSc., CAA, argues that the practice of daylight savings time (DST) negatively impacts sleep and neurological functioning. She explains that REM sleep typically occurs between 3:00 and 4:00 AM, and advancing the clock by one hour eliminates a solid hour of high‑quality REM sleep. Penn frames this loss as a systemic problem, calling DST "horrible" and suggesting that understanding its neurological consequences should become a priority. The short serves as a call‑to‑action for reconsidering DST policy due to its detrimental effects on sleep health.
