Sleep & the Heart: The Hidden Connection & How a Home ECG Monitor Can Help

Man sleeping
We all know sleep is essential for feeling refreshed, but did you know your heart depends on it too? Poor sleep quality has been linked to increased risk of heart problems - and monitoring your heart at home with a home ECG monitor can help you catch issues early.
Studies show that when we sleep, our heart rate and blood pressure naturally decrease, giving the cardiovascular system time to repair. But when sleep is short, fragmented, or low-quality, this recovery is interrupted - raising the risk for high blood pressure, arrhythmias, and heart disease.

Why Sleep Matters for Heart Health

Rest and Repair: Deep sleep allows the heart to slow down and recover from the strain of the day.
Blood Pressure Regulation: A full night’s sleep helps regulate blood pressure, while chronic sleep deprivation can keep it elevated. 
Inflammation Control: Poor sleep can increase inflammation in the body - one of the key contributors to heart disease. 
Heartbeat Rhythm: Irregular sleep patterns have been linked to irregular heart rhythms, especially in individuals with underlying heart conditions.

What You Can Do
Start by building a sleep routine:

- Aim for 7–9 hours of sleep per night
- Go to bed and wake up at the same time daily
- Limit caffeine and screen time before bed

And most importantly - don’t ignore unusual symptoms. If you ever wake up with shortness of breath, chest discomfort, or feel your heart racing, these could be warning signs worth checking out.
