Is Sleeping on the Left Side Unhealthy for Your Heart?

Recent research has raised concerns about the potential impact of sleeping on the left side on heart health. Utilizing vectorcardiography, a technique that measures the heart’s electrical activity, scientists have observed subtle shifts in the heart’s position when individuals sleep on their left side.

A 2018 study, published in the journal “Chest,” investigated the effects of sleeping on the left side in healthy adults. The study found that left-side sleeping was associated with:

• A small increase in the heart’s rotation towards the left, known as left axis deviation
• A decrease in the heart’s size and pumping capacity

These changes were considered subtle and did not appear to have any adverse effects on heart function in healthy individuals. However, the study raises questions about the potential impact of left-side sleeping in individuals with underlying heart conditions.

Potential Risks for Individuals with Heart Conditions

While the research on sleeping on the left side is limited, some experts suggest that it may pose a risk for individuals with certain heart conditions. For example:

• Mitral valve prolapse: Sleeping on the left side can increase pressure on the mitral valve, which can worsen symptoms in individuals with this condition.
• Aortic stenosis: Sleeping on the left side can reduce blood flow to the aorta, which can be problematic for individuals with aortic stenosis.
• Arrhythmias: Sleeping on the left side may trigger arrhythmias in individuals who are prone to them.

Recommendations

If you have a known heart condition, it is advisable to discuss your sleeping position with your doctor. They can assess your individual risks and provide guidance on the best position for you.

For Healthy Individuals

For healthy individuals, there is no clear evidence that sleeping on the left side is harmful. However, if you experience any discomfort or other symptoms when sleeping on your left side, it is recommended to try sleeping on your right side or your back.

Conclusion

While the research on sleeping on the left side is ongoing, it is important to be aware of the potential risks, especially for individuals with underlying heart conditions. If you have any concerns, consult with your doctor for personalized advice.
