Two‑Nap Strategy in Simulated Night Work (90‑min + 30‑min) vs One 120‑min Nap
Summary
Split‑nap strategy reduced fatigue and maintained reaction time better than a single long nap across a 16‑h simulated night.
Why It Matters For Night Shift Workers and Night Owls
Controlled night‑shift conditions how brief, scheduled on‑shift naps (timing/length) in controlled conditions showed sleep & alertness for night‑shift workers and night owls. Findings add structure to the idea that the circadian low can be managed by how rest is divided and timed on duty. For people who work nights, that frames an everyday choice (when you eat, how you light the end of a shift, how rest is split) as part of the mechanism, not just routine.
