The Science Behind Should You Sleep On Your Left Side
Health and Digestive Benefits of Left-Side Sleeping
Sleeping on the left side has been associated with numerous health benefits, especially in terms of enhancing digestive efficiency. This sleeping position is linked to significant potential for overall well-being.
-
Improves Digestion
The stomach and pancreas are naturally positioned leaning towards the left side of the body. When resting on the left side, gravity aids digestion. The food waste moves more easily from the small intestine to the large intestine, facilitating smoother bowel movements. Furthermore, this position allows the pancreas to secrete its enzymes effectively, which are essential for breaking down food particles during digestion. It can be particularly beneficial after a heavy meal, promoting better nutrient absorption and reducing heartburn incidents.
-
Enhances Circulatory System Function
Left-side sleeping benefits the circulatory system. The heart pumps blood out through arteries and receives deoxygenated blood through veins located predominantly on the right side. Sleeping on the left side results in less pressure on these veins leading back to the heart, facilitating smoother circulation throughout the body. This is noteworthy for individuals suffering from conditions like varicose veins or for pregnant women who experience increased blood volume and pressure.
This sleeping posture might feel awkward at first for those accustomed to a different position. However, gradual changes can lead to improvements in both digestive health and circulation efficiency over time.
Heartburn Reduction through Optimal Sleep Positions
Heartburn, a common discomfort experienced by many, often intensifies at night. The relationship between sleep position and heartburn is significant, with gravity and anatomy playing crucial roles.
-
Elevation of the Head: Sleeping flat can facilitate the flow of stomach acid into the esophagus, leading to heartburn. Elevating the head of the bed by 6-8 inches helps maintain stomach acids in their proper place due to the assistance of gravity. This can be achieved using blocks or wedges under the mattress; however, stacking pillows may not be as effective, as it can bend the body in a manner that increases pressure on the abdomen, potentially exacerbating heartburn.
-
Left Side Sleeping: The stomach is positioned slightly left of center within the body. Lying on the right side can cause acid to cover the lower esophageal sphincter (LES), heightening the risk of acid escape into the esophagus and resulting in heartburn. In contrast, sleeping on the left side places the LES above the level of stomach contents, making reflux less probable.
These adjustments aim to reduce the impact of heartburn, thereby enhancing sleep quality and contributing to overall health by minimizing chronic acid exposure which could lead to complications such as Barrett's Esophagus.
Optimal sleep positions and elevation adjustments are associated with a reduction in heartburn symptoms, contributing to improved sleep quality and health.

Neurological Advantages and Snoring Solutions in Side Sleeping
Side sleeping is associated with both neurological benefits and snoring reduction. This article delves into how.
Neurological Advantages
Research indicates a connection between side sleeping and improved brain health. This sleep position is believed to enhance the efficiency of the glymphatic system, a mechanism responsible for removing brain waste, including toxins like beta-amyloid, which is linked to Alzheimer’s disease. The enhanced operation of the glymphatic system in this position suggests a potential for reduced risk of neurodegenerative diseases.
Snoring Solutions
Snoring is often caused by the obstruction of airflow through the airways during sleep. The gravitational pull on the tongue and soft tissues at the back of the throat, which occurs when one sleeps on their back, can narrow the airway and cause vibrations that result in snoring. Side sleeping can help keep these airways open by preventing the gravitational pull on throat tissues, which may lead to a reduction in snoring for individuals who experience mild to moderate snoring.
In summary, side sleeping may play a role in supporting cognitive function and offering a non-invasive approach to mitigating snoring.
Cons of Side Resting and Stomach Slumbering
Sleep positions matter for health. While side resting and stomach slumbering are common, they come with downsides.
-
Side Resting: This position can cause shoulder pain due to pressure on one shoulder throughout the night. It may also lead to jaw discomfort on the side used for sleeping, potentially resulting in temporomandibular joint (TMJ) issues over time. For those with acid reflux or heartburn, resting on the right side can exacerbate these conditions. Pregnant individuals who sleep on their left side for better blood flow might experience hip pain due to prolonged pressure.
-
Stomach Slumbering: Lying on the stomach is tough on the neck and back. To breathe, one must turn the head to one side, which strains the neck muscles and disrupts spine alignment. Over time, this can lead to chronic neck and back pain. Additionally, this position flattens the natural curve of the spine, which may worsen or lead to lower back pain over an extended period.
Both positions have drawbacks that could impact long-term health, which could be mitigated by using pillows designed for specific sleep positions.
Tactics and Pillow Recommendations for Comfortable Side Sleeping
Sleeping on one's side is a preferred position for many, known to potentially reduce snoring and ease discomfort for those with back pain. Achieving the right position involves more than simply turning to one's side, as proper alignment is essential.
For a comfortable side sleeping experience, maintaining a straight spine is important. This helps in reducing pressure on the back and neck. Bending the knees slightly, without pulling them excessively high towards the chest, is recommended to avoid strain.
- Pillow Placement: A firm pillow placed between the knees can help in aligning the hips, which may alleviate lower back tension. For some, a small pillow under the waist could assist in maintaining spinal alignment.
The choice of pillow is crucial for comfort:
-
For the Head: A thick, supportive pillow that fills the gap between the shoulder and head is preferable, ensuring the head is not tilted upwards or downwards.
-
Memory Foam Pillows: These adapt to the shape of the head and neck, offering tailored support.
-
Latex Pillows: Known for their firmness and ability to maintain shape, these pillows are suitable for neck support.
-
Body Pillows: Designed to be long enough for hugging while sleeping on one's side, they provide additional support to both the upper body and legs.
It is recognized that there is no universal solution regarding pillow choices; comfort preferences vary among individuals. Regular assessment of rest quality and any stiffness experienced upon waking can be beneficial.
