What Side Should You Sleep On For Heartburn?

What Side Should You Sleep On for Heartburn?

The simple answer is that sleeping on your left side can help reduce heartburn symptoms. This position helps keep acid in your stomach due to the structure of your stomach and esophagus, providing relief from the discomfort associated with acid reflux. Let’s delve deeper into why this is the case and explore other related aspects you might find beneficial.

The Science Behind Sleeping Positions and Heartburn

Heartburn, also known as acid reflux, occurs when stomach acid travels up your esophagus. When we lie down, gravity can no longer help keep stomach acid down. Different sleeping positions can influence how well your body retains the acid in your stomach. Your stomach is shaped such that its natural curve keeps the acid in place when you lie on your left side. On the right side, however, gravity works against you, making acid reflux more likely.

Anatomy of Your Stomach and Esophagus

Understanding a bit of human anatomy can shed light on why sleeping on your left side is beneficial. Your esophagus connects with your stomach at an angle. When you lie on your left side, the esophagus and stomach align in a way that promotes the natural curve, keeping stomach acid where it should be. On the right side, the stomach is positioned in such a way that acid can easily spill into the esophagus, leading to the symptoms of heartburn.

Other Benefits of Sleeping on the Left Side

While reducing heartburn is a significant advantage, lying on your left side offers various other health benefits. These benefits might make you reconsider your usual sleeping posture.

Improved Digestion

Sleeping on your left side aids better digestion. Your small intestine connects to the large intestine on the left side of your body, and this alignment can help digestive waste move smoothly through the digestive tract. This means your body can process food more efficiently, reducing the risk of digestive discomfort.

Better Lymphatic Drainage

Your lymphatic system, crucial for removing waste from tissues, benefits from left-side sleeping. This sleeping position aids more efficient lymphatic drainage, helping your body detoxify and reducing the load on your lymph nodes.

Enhanced Blood Flow

Your heart is positioned somewhat to the left in your chest cavity. Sleeping on your left side can improve your heart’s efficiency in pumping blood throughout your body. This diminished workload can potentially enhance overall cardiovascular health, a noteworthy benefit for those with pre-existing heart conditions.

Situations Where Right-Side Sleeping May Be Necessary

While left-side sleeping is generally recommended for heartburn relief, some conditions might require you to sleep on your right side or back.


Pregnant women are often advised to sleep on the left side to improve blood flow to the fetus. However, as the pregnancy progresses, comfort can become a significant issue. In such cases, alternating sides can provide relief.

Pre-existing Medical Conditions

Certain health conditions, such as gallbladder issues or specific forms of arthritis, may necessitate different sleeping positions. If left-side sleeping aggravates another medical condition, consult your healthcare provider for personalized advice.

Practical Tips for Falling Asleep on Your Left Side

Transitioning to a new sleep position can be challenging, especially if you have been sleeping differently for years. However, a few simple adjustments can ease the switch.

Pillow Placement

Use pillows to support your body. Place a firm pillow behind your back to prevent rolling over during the night. You can also put a pillow between your knees to align your spine better and reduce the strain on your hips and lower back.

Create a Comfortable Sleep Environment

Comfort is crucial for a good night’s sleep. Ensure that your mattress and pillows support your body appropriately. Memory foam mattresses and contoured pillows can offer the support necessary for left-side sleeping.

Gradual Adjustment

Don’t force yourself into the new position immediately. Gradually train your body by starting on your left side for a few hours each night and then transitioning throughout the week. Allow your body to adapt slowly to make the change less disruptive to your sleep pattern.

What if Left-Side Sleeping Doesn’t Work?

While left-side sleeping is often the best option for heartburn, it’s not a one-size-fits-all solution. If left-side sleeping isn’t reducing your symptoms, you may need to explore other strategies.

Lifestyle and Dietary Changes

Certain foods and activities can exacerbate heartburn. Consider reducing caffeine, spicy foods, and late-night meals. More mindful eating habits can drastically improve your symptoms.

Elevating the Head of Your Bed

Raising the head of your bed about 6 to 8 inches can help. This incline allows gravity to prevent stomach acid from rising. You can use special bed risers or a wedge-shaped pillow for this purpose.

Medication and Medical Advice

Over-the-counter antacids might offer immediate relief but consult a healthcare provider for long-term solutions. Persistent heartburn could be a sign of a more severe condition, such as gastroesophageal reflux disease (GERD), requiring comprehensive treatment.

Other Sleeping Positions and Their Impacts

Let’s briefly look at some other common sleeping positions and their effects on heartburn and overall health.

Back Sleeping

Sleeping on your back isn’t recommended for those prone to heartburn. This position allows stomach acid to move freely up the esophagus. However, a slightly elevated position can help mitigate this issue.

Stomach Sleeping

Stomach sleeping influences your body posture and can worsen heartburn symptoms. This position places undue pressure on your stomach, pushing acid into the esophagus.

Right Side Sleeping

As discussed earlier, this position is generally not recommended for those with heartburn due to the way stomach acid is more likely to escape into the esophagus.

Sleep Hygiene and Heartburn

Good sleep hygiene can support your efforts to manage heartburn and sleep more comfortably. This involves creating an environment and setting habits that promote consistent, uninterrupted sleep.

Regular Sleep Schedule

Go to bed and wake up at the same time every day. This consistency helps improve sleep quality and overall health, including digestive health.

Avoiding Late-Night Meals

Eating large meals or snacks close to bedtime can exacerbate heartburn. Try to have your last meal at least 2-3 hours before bed. Opt for lighter, easy-to-digest foods during the evening.

Limit Alcohol and Caffeine

Both alcohol and caffeine can trigger heartburn. Reduce your intake of these substances, especially in the hours leading up to bedtime.

Stress Management

Stress can impact your digestive system, leading to increased heartburn. Engaging in stress-reducing activities like meditation, reading, or breathing exercises before bed can help.

Finishing Thoughts

Sleeping on your left side can significantly reduce heartburn, providing comfort and better sleep quality. This anatomically advantageous position helps prevent stomach acid from moving up into the esophagus. Besides, it offers additional health benefits like improved digestion, better lymphatic drainage, and enhanced blood circulation.

While left-side sleeping is beneficial, some conditions might require alternative positions. Making gradual adjustments can help you adopt this new sleeping style comfortably. Combining these changes with good sleep hygiene and lifestyle adjustments can further mitigate heartburn symptoms, allowing you to enjoy restful, uninterrupted sleep. Always consult healthcare providers for personalized advice, especially if heartburn persists, to rule out more severe conditions and tailor the right treatment plan for you.
