Figure 1 Experiment protocols. (A and B) Two 8-day protocols in Experiment 1 were designed for non-shift workers, including (A) a circadian alignment protocol with nighttime sleep and (B) a misalignment protocol with nighttime sleep from Day 1 to Day 3, an afternoon nap on Day 4, and daytime sleep from Day 5 to Day 8. (C and D) Two 3-day protocols in Experiment 2 were designed for chronic shift workers, including (C) a circadian alignment protocol with nighttime sleep and (D) a misalignment protocol with an afternoon nap on Day 1 followed by nighttime sleep on Days 2–3.
