This study investigates the comparative analysis of pulmonary functions between kindergarden and secondary school teachers, focusing on the impact of different teaching environments on respiratory health. Utilizing a cross sectional design, 200 participants (100 kindergarden teachers and 100 secondary school teac hers) from urban schools in Delhi NCR India, were selected. Data on vital capacity (VC), peak flow rate (PFR), and maximum breath hold (MBH) were collected through spirometer , along with demographic data such as age, height, weight, BMI, and body fat percentage. Statistical analyses, inclu ding Independent t tests and ANOVA, were performed using SPSS software. The findings revealed that kindergarden teachers exhibited significantly higher VC, PFR, and MBH compared to secondary school teachers, indicating better pulmonary function. These resu lts suggest that environmental factors, such as better ventilation and less exposure to dust in kindergarden environments, contribute to improved respiratory health. The study underscores the need for targeted occupational health interventions and preventi ve measures, particularly for secondary school teachers who are at a higher risk of reduced pulmonary function. This research fills a notable gap in the literature by providing direct comparative data on the respiratory health of teachers at different educ ational levels, offering valuable insights for improving occupational health standards in schools.
