Cardiovascular Health Rhythms

Meaning

Cardiovascular Health Rhythms encompass the cyclical, time-of-day variations in heart rate, blood pressure, vascular tone, and endothelial function, all orchestrated by the body’s internal circadian clock. These rhythms are critical for optimizing cardiac function and minimizing risk factors across the 24-hour cycle; for instance, blood pressure naturally dips during sleep. Maintaining a robust and appropriately timed rhythm, characterized by a proper nocturnal decline, is a key indicator of cardiovascular resilience and autonomic nervous system balance. Disruption of these rhythms, often seen in shift workers or individuals with sleep disorders, is associated with increased incidence of cardiovascular events.
