Impact of Light Therapy on Rotating Night‑Shift Workers
Summary
Intermittent bright‑light therapy had no clear effect on inflammatory markers or glucose tolerance in rotating shift workers.
Why It Matters For Night Shift Workers and Night Owls
Participants randomized in this trial how timing and spectrum of light on shift versus before daytime sleep showed blood sugar 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.
