Which Side Is Best To Sleep On: Left Or Right?
The short answer is that sleeping on the left side is generally considered more beneficial than sleeping on the right. Various studies and expert opinions highlight that the left-side sleeping position may aid in digestion, improve heart health, and alleviate certain medical conditions. While both sides have their advantages, the left side seems to have a bit more to offer in terms of health benefits.
The Science Behind Side Sleeping
Understanding why side sleeping is recommended involves a bit of simple anatomy and physiology. The human body is asymmetrical, and this affects how different sleeping positions influence our health. Key organs and systems are positioned in such a way that sleeping on different sides can have various impacts on digestion, circulation, and even on issues such as acid reflux and heartburn.
Digestive Health
One of the most compelling reasons to sleep on the left side is its impact on the digestive system. The stomach and its gastric juices naturally tend to move towards the right. When you sleep on your left side, gravity helps the acid and other stomach contents stay in their place, reducing the risk of acid reflux and heartburn. The esophagus and stomach connect in a way that creates a seal when lying on the left, essentially reducing the backflow of stomach acids. This makes left-side sleeping particularly useful for people who suffer from gastroesophageal reflux disease (GERD).
Heart Health
Sleeping on the left side can also be beneficial for your heart. The left side of the body houses the heart, and sleeping on this side can improve circulation and reduce pressure on this vital organ. The aorta, which carries oxygenated blood from the heart to the rest of the body, runs from the top of the heart and arcs to the left before descending into the abdomen. Sleeping on the left side allows this aorta to pump blood more efficiently due to the assistance of gravity.
Lymphatic Drainage
The lymphatic system, a crucial component of the immune system, benefits from left-side sleeping as well. The thoracic duct, which is the largest lymphatic vessel in the body, lies on the left side. Sleeping on the left can facilitate the drainage of lymph fluid into the thoracic duct, allowing toxins and waste products to be processed and expelled from the body more efficiently.
Spleen Function
The spleen, another important organ involved in the body’s immune response, also benefits from left-sided sleep. Positioned on the left side of the abdomen, the spleen filters blood, removing old or damaged blood cells and pathogens. By sleeping on your left side, you can enhance the functionality of the spleen, enabling it to filter blood more effectively due to the gravitational pull.
Pregnancy
Pregnant women are often advised to sleep on their left side, especially during the second and third trimesters. This is because the left side sleeping position improves blood flow to the heart, kidneys, and uterus, ensuring optimal oxygen and nutrient delivery to the fetus. It also helps the kidneys to efficiently remove waste products, thus reducing swelling in the hands, ankles, and feet.
Drawbacks of Right-Side Sleeping
While sleeping on the right side does have some benefits, it may come with certain drawbacks. Right-side sleeping can exacerbate acid reflux. The orientation of the stomach and gravity can cause the stomach to release more acid into the esophagus, increasing the risk of heartburn. Additionally, while right-side sleeping might initially feel comfortable, it doesn’t provide the same support for organs like the heart, digestive system, or lymphatic drainage as left-side sleeping does.
Circulatory Issues
Sleeping on the right side can also compress blood vessels, slightly hampering blood flow. This decreased circulation can sometimes lead to issues such as numbness or tingling in the extremities, and in worst-case scenarios, it could exacerbate cardiovascular issues for people already suffering from heart conditions.
Special Considerations and Personal Preferences
Not everyone will find left-side sleeping the most comfortable, and the best position can be influenced by various factors such as personal comfort, existing medical conditions, or even the type of mattress you have. Here are some additional considerations:
Existing Medical Conditions
People with specific medical conditions might need personalized sleeping advice:
– **Shoulder Pain:** Those suffering from shoulder pain or injuries may find sleeping on the affected side uncomfortable. Switching sides or lying on the back might be more advisable.
– **Sleep Apnea:** Some studies suggest that sleeping on the left side can improve symptoms of sleep apnea, particularly in reducing snoring and improving airflow.
– **Back Pain:** While side sleeping is generally good for back pain, a knee pillow can help align the spine and alleviate pressure.
Mattress and Pillow Selection
Your choice of mattress and pillows can also affect how beneficial left-side sleeping will be for you. A mattress that provides adequate support and conforms to your body can help maintain proper spine alignment, reducing the risk of back or shoulder pain. Similarly, the right pillow can ensure your neck and head are supported, enhancing overall comfort and promoting better sleep quality.
Transitioning to Left-Side Sleeping
For those who don’t naturally sleep on their left side, making the switch can be challenging but manageable with some effort. Start by positioning a body pillow behind your back to keep you from rolling onto your right side during the night. Placing a smaller pillow between your knees can also help maintain alignment and provide additional comfort. It may take some time for your body to get used to a new sleeping position, but the health benefits are often worth the effort.
Maintaining a Balanced Approach
While left-side sleeping offers numerous health benefits, it’s essential to maintain balance and listen to your body. Switching between sides periodically can help prevent stiffness and ensure all body systems function optimally. Periodically adjusting your sleep position can also ensure that no specific body part experiences prolonged pressure, preventing stiffness or discomfort.

One often overlooked aspect of side-sleeping comfort is hand and arm positioning. Sometimes, people wake up with numb or tingling arms because of unfavorable positioning. Keeping your arms below the shoulder level and avoiding placing them under your head or pillow can help maintain proper blood circulation and reduce discomfort.
Ideal Bedroom Environment
Creating an optimal sleeping environment can enhance the benefits of left-side sleeping. Ensuring your bedroom is cool, quiet, and dark can promote better sleep quality. Using breathable, comfortable bedding materials can also go a long way in enhancing your overall sleep experience.
Finishing Thoughts
In summary, the left side is generally the more beneficial side to sleep on, offering advantages such as improved digestion, better heart health, and optimized lymphatic drainage. While right-side sleeping isn’t inherently bad, it doesn’t provide the same level of support to your body’s major systems as left-side sleeping does. When choosing your sleeping position, consider your specific health needs, personal comfort, and the type of mattress and pillows you use. By making informed choices about your sleeping habits, you can enhance your overall well-being and wake up feeling refreshed and rejuvenated.
