Many people prefer to sleep on their side because this position is often considered particularly comfortable and can relieve back pain or snoring. But did you know that the side you sleep on can also affect your digestion? In this article, you will learn why it makes a difference whether you sleep on your right or left side, what role your sleeping position plays in preventing heartburn and other digestive problems, and for whom these recommendations are especially important.
1. Why does sleeping position affect digestion?
Our digestive organs are arranged differently in the abdominal cavity. The stomach, which plays a central role in digestion, is mainly located in the upper left abdominal area. Food is broken down in the stomach and then passes through the so-called pylorus into the small intestine.
The position of the stomach and digestive tract means that the sleeping position influences how stomach acid and the food mixture can move within the stomach. The key points are:
-
Left side: When you lie on your left side, the stomach hangs so that the pylorus is below the stomach contents. This means that stomach acid is less likely to flow back into the esophagus, reducing the risk of heartburn.
-
Right side: If you lie on your right side, the pylorus is above the stomach contents. This allows stomach acid to flow back more easily into the esophagus, which promotes heartburn and other discomforts.
These anatomical conditions explain why sleeping position influences digestion and well-being during sleep.
2. Who benefits especially from the left sleeping position?
The positive effect of sleeping on the left side is especially relevant for people with certain health problems:
2.1 People with gastroesophageal reflux disease (GERD)
This disease is characterized by frequent heartburn and reflux (backflow of stomach acid into the esophagus). For those affected, the left sleeping position is particularly recommended because it:
-
Reduces the backflow of stomach acid
-
Relieves symptoms such as heartburn and chronic cough
-
Improves quality of life
2.2 People with digestive problems and bloating
Even with general digestive problems, sleeping on the left side can promote digestion by allowing the food mixture to pass more easily from the stomach into the intestine.
2.3 Pregnant women
During pregnancy, it is often recommended to sleep on the left side because this position improves blood circulation to the placenta, benefiting both mother and child. At the same time, pressure on the stomach and digestive tract is reduced.
3. Is sleeping position important for healthy people?
For people without complaints such as reflux or other digestive problems, the sleeping position is not so critical. The following applies here:
-
No strict necessity to sleep only on the left side.
-
Nevertheless, it can be beneficial to get used to the left side, as it can have positive long-term effects on digestion.
-
Most importantly, find a position that is comfortable and pleasant so that sleep quality is not compromised.
4. Practical tips for the left sleeping position
If you prefer or want to try sleeping on your left side, the following tips can help make the posture more comfortable and healthier:
4.1 Slightly elevate head and upper body
Using a higher neck pillow or an adjustable bed can slightly raise the upper body, which further prevents stomach acid from flowing back.
4.2 Place a pillow between the knees
This supports the spine and prevents tension. It ensures a more natural body posture.
4.3 Do not lie down immediately after eating
Avoid sleeping immediately after a meal. Wait at least two to three hours to allow digestion to start and the stomach to be emptier.
4.4 Match mattress and pillow to your body
A mattress that provides sufficient support and ergonomically shaped neck pillows improve sleep quality and ensure a relaxed posture.
5. What happens if you sleep on your right side?
Many people intuitively sleep on their right side because they find it comfortable. However, this position can lead to digestive discomfort for some:
-
Increased risk of heartburn, especially for people with reflux
-
Unpleasant feeling of fullness or pressure in the stomach
-
Possibly poorer sleep due to waking up at night because of digestive problems
If you frequently suffer from heartburn or acid regurgitation, you should critically review your sleeping position.
6. Consider personal differences
There is no "one-size-fits-all" solution for everyone. Every body is different, and some feel more comfortable on the right side while others prefer the left.
What is important:
-
Listen to your body! If you wake up with discomfort after sleeping, the sleeping position could be a cause.
-
Try out which position helps you best.
-
If symptoms persist, it is advisable to see a doctor to clarify causes.
7. Other factors that influence digestion and sleep
Besides sleeping position, there are other important factors that affect your digestion and sleep quality:
-
Nutrition: Avoid heavy, fatty, or heavily spiced foods before going to bed.
-
Meal times: Regular meals and spacing between eating and sleeping promote better digestion.
-
Weight: Overweight can increase pressure on the stomach and promote reflux.
-
Stress: Stress and psychological burdens negatively affect digestion and sleep.
-
Alcohol and nicotine: Both substances can increase stomach acid production and cause sleep problems.
8. Summary and conclusion
The sleeping position – especially whether you lie on your left or right side – has a measurable impact on your digestion and well-being during the night. For people with digestive complaints, especially heartburn and reflux, sleeping on the left side is a simple and effective measure to relieve symptoms.
Healthy people can also benefit from the left sleeping position but do not necessarily have to pay attention to it as long as they feel comfortable and sleep well.
It is always important to choose a sleeping position that is comfortable and offers the best possible rest. If you have problems, you should seek medical advice.
9. Further tips for healthy sleep and digestion

Regular sleep times: A consistent rhythm supports the natural biorhythm.
-
Exercise: Regular physical activity promotes healthy digestion and improves sleep.
