Evening types had better tolerance of night shifts but worse on early shifts; morning types the reverse—highlighting chronotype‑schedule fit.
Evidence here how timing and spectrum of light on shift versus before daytime sleep shows sleep & alertness for night‑shift workers and night owls. Together with other trials, it frames light as a measurable lever for on‑shift alertness and next‑day sleep, not just ambience. 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.
