When you settle down for the night, you might start thinking about your heart. Is it harmful to sleep in a specific position, like on your left side? We reached out to a cardiologist to help clear up the confusion about this topic and discuss the bigger picture of heart health and how to manage risks more effectively.
The Connection Between Sleep and Heart Health
Sleep is like the body’s housekeeper, clearing out toxins and reducing stress and inflammation—factors often linked to chronic illnesses.
“Good sleep, particularly getting enough of deep and REM sleep, is vital for heart health,” explains Dr. Renato A. Apolito, a cardiologist at Jersey Shore University Medical Center, noting that sleep apnea is a significant factor connecting sleep and heart health.
Is Left-Side Sleeping Bad for Your Heart?
You might have heard that sleeping on your left side could exert more pressure on your heart—particularly for those with heart conditions. However, Dr. Apolito states there isn’t any solid research supporting that idea.
“Overall, we don’t have strong evidence proving that any one sleep position is decidedly better for the heart,” he explains. “It largely depends on the individual—considering factors like comfort, orthopedic needs, and body type. Plus, people tend to change positions during the night.”
The body is generally quite adaptable, he adds. “What’s really important is if a given position impacts your breathing—like if it causes airway obstruction or leads to musculoskeletal issues, such as sleeping on your stomach, which we usually don’t recommend.”
Sleep Apnea: The Greater Risk
Now that the concern about sleep position has been addressed, it’s important to focus on another, often overlooked issue: sleep apnea. This condition “can lead to high blood pressure and increase the risk of atrial fibrillation,” according to Dr. Apolito. While it’s more frequently found in individuals with larger neck circumferences or certain body types, it can still occur in people of average weight. The key is getting a proper diagnosis.
Here are some main symptoms of obstructive sleep apnea to be aware of:
- Daytime fatigue: Feeling tired even after a full night’s sleep.
- Falling asleep during normal tasks: Nodding off while working at your computer or even driving.
- Poor sleep quality: Tossing and turning or waking up frequently during the night.
- Snoring or breathing interruptions: If you have a partner, they might notice you snore loudly or briefly stop breathing while asleep.
If you think you might be experiencing sleep apnea, it’s a good idea to consult your doctor. Testing is straightforward, and treatments, often involving a CPAP machine or other methods, can significantly enhance your sleep quality and heart health.
The Main Takeaway About Sleep Position and Heart Health
“Sleep position isn’t a primary concern for heart health,” Dr. Apolito concludes. “Sleep apnea and overall sleep quality matter much more.” So, it’s best to sleep in whatever position feels comfortable to you, even if that’s on your left side. The most crucial thing is to ensure you’re getting seven to nine hours of quality sleep and being alert to potential sleep apnea symptoms. Taking those simple steps will benefit your heart health more than stressing over a particular sleeping position.
