Abstract
Cardiovascular events such as stroke and myocardial infarction frequently occur in the morning.
- Circadian rhythms in the body help prepare the cardiovascular system for daily activity patterns.
- Morning responses of the cardiovascular system may support the transition from sleep to wakefulness.
- Exaggerated cardiovascular responses in the morning could increase risk for individuals prone to events like heart attacks.
- Chronic disruptions of the circadian clock, such as those experienced by night-shift workers, may elevate cardiovascular risk.
- Understanding the circadian system's role is essential for improving cardiovascular function and managing cardiovascular diseases.
