Sleep Fragmentation and Next-Day Attentional Lapses: A Field Study Using Wearable Actigraphy

Abstract

There is real interest in sleep fragmentation and next-day attentional lapses right now, and real uncertainty about exactly where it
delivers the most value. We pull together the current evidence for sleep fragmentation and next-day attentional lapses, covering
the methodological, practical, regulatory and cost angles, with an eye on where practice has genuinely settled and where
researchers and reviewers are still largely working it out for themselves. Selective, context-specific pursuit looks better supported
by the evidence gathered here than either broad rollout or blanket avoidance.
