Understanding Acid Reflux
Acid reflux, also known as gastroesophageal reflux disease (GERD), is a common condition where stomach acid flows back into the esophagus, causing discomfort, heartburn, and other symptoms. It often occurs when the lower esophageal sphincter (LES), a muscle at the junction of the esophagus and stomach, weakens or relaxes abnormally. Acid reflux can be aggravated by eating certain foods, lying down soon after meals, or sleeping in a position that makes it easier for stomach acid to travel upward.
Best Sleeping Position for Acid Reflux
The best side to sleep on if you suffer from acid reflux is the left side. This position can help reduce the symptoms of acid reflux and promote better digestion.
Why the Left Side is Beneficial
Sleeping on your left side can be particularly effective for managing acid reflux because of the body’s natural anatomy and the position of the stomach and esophagus. When you sleep on your left side, your stomach lies below the esophagus, creating a downward angle for the digestive acid. Here are some detailed reasons why this position works:
Gravity’s Role
Gravity plays a vital role in maintaining the contents of your stomach in place. When you sleep on your left side, gravity helps to keep the acid where it belongs – in your stomach. This reduces the chances of acid reflux symptoms, such as heartburn or regurgitation.
Improved Stomach and Esophagus Alignment
The anatomical design of your stomach and esophagus is crucial in how effectively acid reflux is managed. The stomach is naturally angled to the left side. When you lie on your left side, the entry point from the esophagus to the stomach sits higher than the rest of the stomach contents, creating a natural anti-reflux barrier.
Avoiding the Right Side
Sleeping on the right side may worsen acid reflux symptoms. This position places the stomach in a manner that encourages the flow of stomach acid back into the esophagus.
The Mechanism
When you sleep on your right side, your stomach is positioned above the esophagus. This positioning means gravity works against you, making it easier for the acid to escape into the esophagus, leading to heartburn and discomfort.
Scientific Explanation
Several studies have confirmed that people who sleep on their right side experience more frequent and severe acid reflux symptoms compared to those who sleep on their left. This evidence suggests that the right side sleeping position compromises the function of the LES, further allowing the backflow of acid.
Other Sleeping Positions
While sleeping on your left side is the most recommended position for reducing acid reflux, other positions also have varying effects on the condition.
Sleeping on Your Back
Sleeping on your back can be both good and bad, depending on your posture and use of pillows.
Head Elevation
When you sleep on your back with your head elevated, it helps keep stomach acid in the stomach. You can achieve elevation by using a wedge pillow or elevating the head of your bed about 6 to 8 inches. This ensures that gravity works for you, preventing acid from going back up to the esophagus.
Flat Back Sleeping
Conversely, if you sleep flat on your back without raising your head, it could increase acid reflux symptoms. In this position, stomach acid can easily flow into the esophagus, particularly if the LES is already weakened.
Stomach Sleeping
Sleeping on your stomach is generally discouraged for people with acid reflux. This position exerts pressure on the stomach, potentially forcing acid into the esophagus.
Combination Sleeping
Some people naturally shift positions during sleep. If you find it challenging to maintain one position throughout the night, try to at least start your sleep on your left side. Using pillows to prevent rolling over can help maintain this beneficial position.
Practical Tips for Better Sleep with Acid Reflux
In addition to choosing the correct sleeping position, certain lifestyle changes and practical measures can help manage acid reflux more effectively.

Eating large or heavy meals close to bedtime can increase the probability of experiencing acid reflux symptoms. Aim to finish eating at least 2 to 3 hours before going to bed. This allows time for digestion and reduces the amount of acid in the stomach.
Choosing the Right Foods
Identify and avoid foods that trigger your acid reflux. Common culprits include spicy foods, citrus fruits, tomatoes, chocolate, peppermint, and fatty or fried foods. Keeping a food diary can help you track which foods exacerbate your symptoms.
Elevate the Head of Your Bed
Raising the head of your bed by 6 to 8 inches can help reduce symptoms. You can use blocks or risers under your bed posts or a specially designed wedge pillow. This elevation uses gravity to keep acid in your stomach and away from the esophagus.
Maintain a Healthy Weight
Excess weight, particularly around the abdomen, can increase abdominal pressure, pushing stomach contents against the LES and causing acid reflux. Losing weight through a balanced diet and regular exercise can help reduce symptoms.
Avoid Alcohol and Caffeine
Both alcohol and caffeinated beverages can relax the LES, making it easier for stomach acid to travel back up the esophagus. Limit or avoid these beverages, especially in the evening.
Wear Loose-Fitting Clothing
Tight clothing, particularly around the waist, can put additional pressure on the stomach. Opt for loose-fitting clothes, especially when lying down or going to bed.
Quit Smoking
Smoking can weaken the LES and increase acid production. Quitting smoking is beneficial not only for reducing acid reflux but also for improving your overall health.
Consulting with Healthcare Providers
If you continue to experience significant acid reflux symptoms despite making these changes, it is crucial to consult with a healthcare provider. Persistent acid reflux can lead to complications such as esophagitis, strictures, or Barrett’s esophagus.
Prescription Medications
A doctor may prescribe medications such as proton pump inhibitors (PPIs), H2-receptor antagonists, or prokinetics to help reduce stomach acid production and improve LES function. Prescription medications can be more effective for severe or persistent cases.
Medical Procedures
In some cases, surgical intervention may be necessary to strengthen the LES and reduce acid reflux. Procedures such as fundoplication or the insertion of a LINX device can provide long-term relief.
Finishing Thoughts
Acid reflux can significantly impact your quality of life, especially your sleep. By consciously choosing to sleep on your left side and adopting various lifestyle changes, you can better manage and reduce the symptoms of acid reflux. Remember that while these strategies can be extremely beneficial, consulting with a healthcare provider for persistent or severe symptoms is essential. With the right approach and care, you can achieve more restful sleep and better overall health.
