Sleep On Which Side For Heartburn?

Optimal Sleeping Position for Heartburn Relief

If you’re experiencing heartburn, especially at night, you may find relief by sleeping on your left side. This position may be beneficial because it can help reduce the backflow of stomach acids into the esophagus, which can cause the unpleasant burning sensation known as heartburn.

Understanding Heartburn and Its Causes

Before we delve deeper into why the left-side sleeping position is advantageous, let’s first understand what heartburn is. Heartburn occurs when stomach acid flows back into the esophagus—a tube that carries food from your mouth to your stomach. This backwash, known as acid reflux, can irritate the lining of your esophagus and lead to heartburn.

Several factors can contribute to heartburn, including:

  • Eating Habits: Consuming large meals or eating late at night can trigger heartburn. Certain foods and beverages such as coffee, alcohol, chocolate, and spicy or fatty foods may also worsen symptoms.
  • Lifestyle Factors: Smoking, obesity, and wearing tight clothing can exacerbate heartburn symptoms.
  • Medical Conditions: Conditions such as gastroesophageal reflux disease (GERD), pregnancy, and hiatal hernia can increase the likelihood of experiencing heartburn.
  • Medications: Certain medicines, including aspirin, ibuprofen, and some muscle relaxants and blood pressure medications, can contribute to or worsen heartburn.

Why Sleeping on Your Left Side May Help

Anatomy and Gravity

The idea behind left-side sleeping stems from the concept of anatomy and gravity working together. When you lie on your right side, your stomach is higher than your esophagus, which can allow gravity to help stomach acid travel upward into the esophagus. Conversely, sleeping on your left side positions the stomach lower than the esophagus, which can reduce the risk of acid creeping up into the esophageal tract.

Gastric Emptying

Another factor to consider is the process of gastric emptying. When you sleep on your right side, food and gastric juices may pool in the stomach, slowing down the emptying process and prolonging the time during which reflux can occur. Left-side sleeping aligns the stomach and the esophagus in a way that may promote smoother, more efficient digestion and quicker gastric emptying, which is likely to decrease the potential for heartburn.

Studies and Recommendations

Various studies support the theory that left-side sleeping can help minimize heartburn symptoms. For instance, research published in “The Journal of Clinical Gastroenterology” found that lying on the left side can reduce nighttime reflux episodes. Based on these findings, many healthcare professionals recommend that patients with GERD or heartburn try sleeping on their left side to manage their symptoms.

Additional Tips for Managing Heartburn During Sleep

While sleeping on your left side can be helpful, there are other strategies you can employ to further reduce the occurrence of heartburn while you rest.

Elevate Your Head

Raising the head of your bed by about six to eight inches can help prevent acid from flowing back into the esophagus. You can achieve this by using a wedge pillow or by placing blocks under the legs at the head of your bed.

Maintain a Healthy Weight

Excess weight can put additional pressure on your abdomen, increasing the likelihood of acid reflux. Maintaining a healthy weight through diet and exercise may reduce the frequency of heartburn episodes.

Be Mindful of Your Diet

Avoid foods and beverages that are known to trigger heartburn. It’s also wise to avoid eating large meals or snacking too close to bedtime, as a full stomach can increase the chances of acid reflux.

Modify Your Lifestyle

If you smoke, quitting can improve your heartburn symptoms, as smoking relaxes the muscles that help keep acid in the stomach. Limiting alcohol consumption and wearing loose-fitting clothing can also alleviate pressure on the stomach and may help reduce reflux.


If lifestyle modifications are insufficient, medications like antacids, H2-receptor blockers, or proton pump inhibitors may help manage heartburn. Consult with a healthcare provider to discuss the best treatment options for your specific needs.

Finishing Thoughts

While heartburn can be a frustrating and uncomfortable condition, adopting simple changes such as sleeping on your left side can make a significant difference in managing symptoms. Along with the other strategies mentioned, this sleep position can help you achieve a more restful night without the disruption of heartburn. Remember, if you have frequent heartburn or suspect GERD, it’s important to seek medical advice to ensure proper treatment and to rule out other potential health issues. Effective management and understanding of your body’s responses to different sleep positions and lifestyle choices are key to reducing the discomfort associated with heartburn and improving your overall quality of life.
