Six Hours of Sleep or Less May Take a Toll on Your Heart

Getting six hours of sleep or less a night may have consequences beyond feeling tired the next day. When short nights become a regular pattern, they may also affect cardiovascular health.

Fatigue and difficulty concentrating are among the more noticeable effects of insufficient sleep. But feeling able to get through the day does not necessarily mean the body is getting the rest it needs.

Sleep helps the body regulate functions involved in heart health, including blood pressure. Persistently inadequate rest can disrupt those processes, making sleep an important part of cardiovascular care rather than simply a matter of comfort.

The concern is habitual sleep loss, not a reason to assume that an occasional short night will cause heart disease. Making time for consistent, sufficient sleep—and seeking medical advice when sleep problems persist—can help address a potentially overlooked health risk.
