NCT ID NCT04959838
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tracks 30 eye doctors and residents in France to see how working up to 60 hours straight affects their stress levels, heart rate, and surgical skills. Researchers will measure heart rate variability, saliva stress markers, and sleep quality. The goal is to understand if long night shifts increase the risk of medical errors and long-term health problems.
