Introduction: the heart recovers during sleep

Sleep is not only rest; it is a vital restorative process for the heart and vessels. Sleep deprivation or irregular sleep can raise blood pressure, worsen arrhythmias, and even increase myocardial infarction risk.

At Delban Cardiology Clinic in Mashhad, sleep quality is treated as a key pillar of heart-healthy living.

How much sleep is enough?

For most adults:

• 7 to 8 hours of nighttime sleep
• Consistent hours (preferably ~10–11 pm to 5–6 am)
• Continuous sleep without frequent awakenings

Long but irregular sleep does not replace regular sleep.

Sleep and heart disease

Poor or insufficient sleep can cause:

• Higher nighttime blood pressure
• Increased heart rate
• Activation of the stress (sympathetic) system
• Greater vascular inflammation
• Worsening heart failure

Patients with insomnia or sleep apnea are at higher risk.

Warning signs of poor sleep

• Persistent daytime fatigue
• Nocturnal palpitations
• Waking with shortness of breath
• Morning headache
• Severe daytime sleepiness

Consequences of irregular sleep

• Poor blood pressure control
• More arrhythmia episodes
• Worsening nocturnal dyspnea
• Higher risk of heart attack and stroke
• Reduced effectiveness of cardiac medications

Healthy sleep principles for cardiac patients

• Go to bed and wake up at fixed times
• Avoid caffeine and strong tea after afternoon
• Avoid phones/TV before bed
• Eat a light dinner (at least 3 hours before sleep)
• Left-side sleeping may help some cardiac patients

When sleep needs medical assessment

• Loud snoring
• Witnessed sleep apnea
• Nocturnal dyspnea or palpitations
• Frequent awakenings
• Severe daytime sleepiness

Summary

Adequate, regular sleep is one of the most important—and most overlooked—factors in controlling heart disease. Improving sleep can meaningfully improve blood pressure, heart rate, and quality of life.
