![]() ![]() In fact, there are three distinct groups of people that may do worse. Not everyone does best with right side sleeping. And when it comes to sleeping and sympathetic stimulation, studies show that right-sided sleeping may be better. This fight or flight response makes the heart rate and blood pressure go up.įor most of my patients, sympathetic nervous system stimulation makes their heart failure, chest pain, or arrhythmias worse. The sympathetic nervous system is the fight or flight response. Lower Heart Rate and Less Sympathetic Nervous Activity ![]() Thus, when it comes to sleeping and arrhythmias, I suggest sleeping in whatever position that seems to help. While many atrial fibrillation patients have noted that they have fewer arrhythmias when sleeping on the right side, I could find no studies supporting this finding. In contrast, when you are on your left side, the heart is pulled to the chest wall, and you may feel every irregular beat of your heart. As the heart is in the center of your chest with right-sided sleeping, studies show that palpitations become much less noticeable. No one likes the sensation that their heart isn’t beating correctly. Once again, gravity pulling the heart toward the center of the chest may optimize cardiac performance. Better Cardiac Outputįor the same reasons as number one above, cardiac output may be better with right side sleeping. While the reason for this isn’t entirely clear, it may have to do with a better venous return and lower pressures within the heart and lungs. Indeed, the worse the cardiac function, the more likely people are to sleep right side down. Less Shortness of BreathĪs far back as 1937 doctors have noted that heart patients breath better sleeping on their right side. Based on the science, here are four reasons why you may want to consider sleeping on the right. If you suffer from heart issues, talk with your doctor about whether you should sleep on your right or left side. However, as I have learned personally, stomach sleeping is a perfect recipe for neck and back issues. And studies show that sleep apnea dramatically increases your risk of heart failure and atrial fibrillation. This is because when you sleep on your back, the extra weight collapses your airway (sleep apnea). If you are carrying any extra weight, back sleeping is definitely bad for your heart. Why Back Sleeping is Probably Bad for the Heart This subtle change in where gravity pulls your heart may affect symptoms, cardiac output, or even your heart rate. ![]() In contrast, gravity pulls the heart toward the center of the chest with right side sleepers. For example, if you sleep on your left side, then gravity will pull your heart toward your chest wall. Gravity plays a role in where the heart goes during sleep. Gravity and Left vs. Right Side Sleeping? Is right side sleeping best for your heart? In this article, I discuss the science of behind right versus left side sleeping.
