Two‑nap strategy in simulated night work: a 90‑min followed by a 30‑min nap maintains performance
Summary
In night‑shift simulations, a split‑nap (90 + 30 min) strategy reduced fatigue and stabilized reaction times compared with a single long nap.
Why It Matters For Night Shift Workers and Night Owls
Alternating conditions in this trial how brief, scheduled on‑shift naps (timing/length) found 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.
