Simple eye mask boosts sleep in intensive care patients

This study tested whether wearing a light-blocking eye mask at night (11 p.m. to 5 a.m.) could improve sleep quality and melatonin levels in 60 intensive care unit patients. Participants were randomly assigned to either wear the mask or receive standard care. Sleep quality was measured using questionnaires, and melatonin levels were checked through urine samples. The goal was to see if a simple, drug-free intervention could help patients rest better and support their natural day-night rhythm.
