Online published on 21 November, 2019. Abstract Background Urban working population lead a busy stressful life with poor sleep quality and health. The present study targets working population including both Shift and Non-Shift (9am-6pm) workers to analyse their sleep quality and heart rate variability and to evaluate for association between them. Objectives This study aims to analyse Sleep quality and Heart Rate Variability (HRV) in working population of Bengaluru and to evaluate for association between these two parameters in the study group. Materials and Method 50 professional workers in the age group of 20-35yrs were subjectively analysed for their quality of sleep using Pittsburgh Sleep Quality Index (PSQI). HRV was recorded with finger photoplethysmograph using infrared light, placed on left index finger of subjects. The analog signals of the device were digitized and reported through Kubios HRV software. Results Sleep quality and HRV indices were found to be better in people working from 9am-6pm shifts (Non-Shift workers) compared to people working in other shifts. Significant correlation between Sleep quality and HRV indices was observed. Conclusion Non-shift workers have better Sleep quality and HRV indices compared to Shift workers in Bengaluru city.
