Non‑Pharmacological Interventions to Improve Chronic Disease Risk Factors and Sleep in Shift Workers: A Systematic Review and Meta‑Analysis
Summary
Synthesizes trials and interventions (e.g., lighting, scheduling, naps, diet/activity) showing modest improvements in sleep and cardiometabolic risk factors among shift workers.
Why It Matters For Night Shift Workers and Night Owls
Pooled evidence 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.
