Tested a multimodal program (education, scheduling tweaks, light, naps) vs control; reported improvements in perceived fatigue, sleepiness, and cardiometabolic markers.
A randomized trial how brief, scheduled on‑shift naps (timing/length) 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.
Intervention details useful for workplace pilots.
