One definitive, printable reference per schedule: the whole rotation walked end to end, every claim cited, maintained as the evidence moves. More are being written; each takes as long as it takes.
Firefighters · EMS
The tour, on-shift napping under the tones, the drive home, and why the recovery day and the reset day do different jobs. Cited to the 2025 AASM guideline and primary trials.
Nurses · night workers
Three twelve-hour nights and the two transitions that actually cost you: going in, and coming out. The pre-shift nap, light on shift, defending day sleep, and the first night back.
Until your schedule has its own guide: the Field Manual covers the foundations that survive any rotation, the schedule pages carry a worked example for nine patterns, and the free plan builder computes your own numbers in two minutes.
