Effects of Sleep Patterns on Cardiovascular Health

Cardiovascular disease (CVD) remains a leading cause of death worldwide, and its rising prevalence is attributable to modifiable lifestyle factors, including poor diet, physical inactivity, and chronic stress. Among these factors, sleep patterns are increasingly recognized as a critical determinant of cardiovascular health. Substantial evidence indicates that insufficient sleep – encompassing sleep deprivation, poor sleep quality, and irregular sleep duration – is significantly associated with elevated risk of hypertension, coronary artery disease, arrhythmias, stroke, and other cardiovascular disorders. Herein, we examine the intricate mechanisms linking sleep patterns to CVD, and specifically address how sleep quality, duration, and regularity directly or indirectly influence neuroendocrine regulation, immune-metabolic homeostasis, and overall cardiovascular function. We further discuss the cardioprotective mechanisms of healthful sleep and its role in mitigating CVD burden, particularly in high-risk populations. Effective preventive strategies include sleep hygiene optimization, cognitive behavioral therapy for insomnia (CBT-I), novel interventions, OSA-specific management, and improvement of occupational/living environments. Future research should focus on integrating digital monitoring for early detection of sleep disturbances, and developing personalized interventions leveraging big data and artificial intelligence. We conclude by advocating for further investigation of the long-term cardiac effects of sleep and the incorporation of sleep management into comprehensive CVD prevention programs.
