Over 50% of NYS teachers reported almost all health symptoms worsening during workdays. We found the top five most common health symptoms reported by NYS teachers are all allergy-related symptoms. Additionally, all extreme thermal factors were significantly associated with work-related symptoms in teachers. “Too dry” had the highest risk for allergic symptoms (OR: 2.49, 95% CI: 2.01-3.10), and then followed by any noise (OR: 2.46, 95% CI: 1.80-3.36) associated with voice-related health, and “lighting too dim” (OR: 2.38, 95% CI: 1.77-3.19).
