Background: Recently, manifestation of global environmental changes is important. Environmental changes temperature and humidity may affect on respiratory dynamics.
Aims and Objectives: The aim of this study is to identify the outcomes of seasonal effect on pulmonary function.
Materials and Methods: This was a cross-sectional study based on the seasons using result from spirometry, questionnaires to investigate the participantsÂ’ respiratory system, sedentary and smoking habit, etc. Anthropometric parameter has been taken. All participants are performed spirometry. Spirometry values were tabulated with mean, median, and coefficient of variation.
Results: The spirometry assessment, based on the seasons was significant. Forced vital capacity (FVC), forced expiratory volume in 1-s (FEV1), and peak expiratory flow rate values were significantly increase in winter, but FEV1/FVC and forced expiratory flow between 25% and 75% decrease with increasing environmental temperature.
Conclusion: Respiratory rate and capacity change with seasons.
Key words: Spirometry; Forced Vital Capacity; Season; Summer; Winter
