Which mask wins? study tests N95 vs surgical mask for smoke symptoms
NCT ID NCT07404956
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether surgical masks or N95 masks work better to reduce physical symptoms like headache, fatigue, and muscle pain caused by surgical smoke in operating room nurses. 38 nurses wore each type of mask for four weeks and reported their symptoms. The results showed that N95 masks helped with muscle issues, while surgical masks were better for breathing and eye irritation.
