An Observational Epidemiological Design to Investigate the Correlation Between Sleep Duration and Cardiovascular Health

Public health campaigns promote healthy sleep habits and early intervention for sleep syndromes are essential to reduce the threat of cardiovascular disease and enhance overall health outcomes. Sleep reduces HR and BP, which promotes cardiovascular healing. However, excessive SD can disrupt these restorative effects, increasing susceptibility to hypertension and arrhythmias, among other cardiovascular problems. This study investigates the connection among heart rate (HR), blood pressure (BP), and sleep duration (SD). The Pearson correlation coefficient captures the relationship established among the variables. The strongly negative association between BP and SD of -0.18 shows that more sleep has no discernible effect on lowering BP. At -0.52, the correlation between HR and SD is stronger, indicating a discernible drop in HR with more sleep. Those who slept for 7.5 to 8 hours had improved heart health in terms of both BP and HR, according to the study, which examined $\mathbf{3, 7 5 5}$ participants.
