Abstract
Introduction: Peak Expiratory Flow Rate (PEFR) measures the highest speed at which a person can exhale and is a crucial indicator of respiratory health. Environmental factors, particularly high humidity, can impact respiratory function. This study aims to compare the impact of humidity on PEFR between heavy-duty and non-heavy duty workers, providing insights into occupational health risks and informing strategies to mitigate them. Aim and Objectives: The primary aim was to investigate the impact of high humidity on PEFR in heavy-duty workers compared to non-heavy duty workers. Specific objectives included measuring and comparing PEFR values between the two groups under high humidity conditions and assessing the prevalence of respiratory symptoms. Material and Methods: A cross-sectional study was conducted with 50 participants from the Kalol, Gandhinagar, Gujrat, India, divided into 25 heavy-duty and 25 non-heavy duty workers. PEFR measurements were taken using a standardized peak flow meter under high humidity conditions (above 75%). Demographic data and occupational histories were collected through structured questionnaires. Results: Significant differences in PEFR were found between heavy-duty and non-heavy duty workers under high humidity conditions. The average PEFR for heavy-duty workers was 350 ± 25 L/min, compared to 420 ± 30 L/min for non-heavy duty workers (p < 0.01). Symptoms like shortness of breath, cough, chest tightness, and fatigue were more prevalent among heavy- duty workers. Conclusion: High humidity significantly impacts the respiratory function of heavy-duty workers, evidenced by reduced PEFR. Implementing effective occupational health measures, such as hydration, rest breaks, and protective equipment, is crucial to mitigate the adverse effects of high humidity on respiratory health.
