Introduction: Sleep duration and sleep quality have been reported to be linked to an increased risk of hypertension among industrial workers. This study aimed to explore this association among industrial workers. Methods:A case-control study was conducted among 88 hypertensive patients and 175 control non-hypertensive groups from industrial workers. Data were collected using the Tamil-Pittsburg Sleep Quality Index (T-PSQI) by personal interview with the hypertensive and control groups. Logistic regression was used to analyze the relationship between sleep duration, sleep quality, and hypertension. Result:Out of 263 industrial workers, hypertension prevalence was 33.4%. Among shift workers, 46.7% reported poor sleep. Data on sleep duration and quality were collected via questionnaires. There was a statistical association between poor sleep quality and sleep duration. Conclusion:Sleeping more than 10 hours is associated with hypertension among industrial workers. Additionally, poor sleep quality is independently associated with ever-smoking individuals, and BMI is independently associated with short sleep duration (<7 hours) in these workers
