Sleep and Your Heart: What Our Cardiologists Watch For

Sleep and your heart

When patients come to our cardiology clinic, we ask about sleep almost as often as we ask about diet and exercise. Poor sleep and heart health are closely linked, and improving one often helps the other.

Why sleep matters for the heart

During deep sleep, heart rate and blood pressure naturally drop, giving the cardiovascular system time to recover. Regularly short or broken nights keep that system under strain for longer.

Signs worth mentioning

Loud snoring, pauses in breathing noticed by a partner, waking up gasping, or feeling exhausted despite a full night in bed can all point to sleep apnea, which is linked to high blood pressure and heart rhythm problems.

Small changes that help

Keep a regular bedtime, limit caffeine after midday, avoid heavy meals late in the evening, and keep screens out of the bedroom. These habits support both better sleep and steadier blood pressure.

When to book a visit

If you have any of the signs above, or a family history of heart disease, book a cardiology consultation. A simple assessment and, if needed, a sleep study can clarify what is going on.
