Which is the Best Position to Sleep: Left or Right Side? Explore the Answer!
The perceived benefits of left side sleeping are based on various studies and expert opinions. While both left and right side sleeping have potential advantages, some argue and Ayurveda aspects that left side sleeping may offer slightly more benefits, particularly in certain situations like pregnancy or for individuals with digestive issues.

Sleep is an essential aspect of our daily lives, impacting our overall well-being. One crucial factor in achieving a good night's sleep is the position in which we rest. 

Consider any specific health conditions you may have and experiment with different positions to find what works best for you. Here, we will explore the age-old debate: which is the best position to sleep - left or right?

Left Sleeping Position

Sleeping on your left side has long been hailed for its potential health benefits. Let's dive into the advantages and drawbacks associated with this favored sleep position.


  • Digestive Aid: One of the primary advantages of left-side sleeping is its positive impact on digestion. This position encourages food to flow more easily from the stomach to the intestines, aiding in smoother digestion.
  • Acid Reflux Relief: Right-side sleeping may help alleviate symptoms of acid reflux. This position prevents stomach acid from flowing back into the esophagus, reducing the likelihood of heartburn.
  • Heartburn Reduction: For individuals prone to heartburn, sleeping on the right side can be beneficial. It minimizes the chances of stomach acid irritating the lower esophageal sphincter.
  • Heart Health: Left-side sleeping may promote better heart health by reducing the strain on the heart. It allows the heart to pump blood more efficiently, facilitating optimal circulation.
  • Pregnancy Comfort: For pregnant individuals, sleeping on the left side is often recommended. This position improves blood flow to the uterus and fetus, reducing the risk of complications.


  • Organ Pressure: Despite its benefits, left-side sleeping may exert pressure on certain organs, including the lungs and stomach. This could potentially lead to discomfort for some individuals.
  • Nerve Compression: Prolonged left-side sleeping might cause nerve compression, leading to numbness or tingling in the arm or shoulder.

Right Sleeping Position

While not as commonly discussed as its counterpart, sleeping on the right side also has its unique set of advantages and disadvantages.


  • Heart Health: A 2018 studyTrusted Source shows that sleeping on the right side lowers pressure on the heart muscles by creating more space in the chest cavity. An older study reports that people with congestive heart failure (CHF) felt more uncomfortable when lying on their left side.

  • Reduced Snoring: Similar to left side sleep, sleeping on the right side may help reduce snoring for some individuals. By keeping the airways open and minimizing obstructions in the throat, right side sleeping can contribute to a quieter and more restful sleep.


  • Back Pain Concerns: Those dealing with back pain may find that sleeping on the right side exacerbates their discomfort. It might not be the ideal choice for individuals with pre-existing back issues.
  • Digestive Challenges: Unlike left-side sleeping, this position may not promote optimal digestion. Some individuals may experience slower digestion when sleeping on their right side.

In summary, the choice between left and right sleeping positions depends on various factors, including personal comfort and existing health conditions. Understanding the pros and cons of each position can help you make an informed decision that contributes to a restful night's sleep.

Understanding the impact of sleep positions on health and considering specific conditions is crucial for making informed choices that contribute to overall well-being. It's advisable to consult with healthcare professionals, especially for those with pre-existing health concerns, to ensure the chosen sleep position aligns with individual health needs.

Sleep Quality:

The quality of your sleep is not solely dependent on the duration but also on the sleep position you choose. Let's explore how left and right sleeping positions can influence your overall sleep quality.

1. Impact on Deep Sleep:

  • Left Side: Some studies suggest that left-side sleeping may enhance the quality of deep sleep, leading to a more restorative and rejuvenating rest.
  • Right Side: While not as extensively studied, right-side sleeping is generally considered conducive to deep sleep, especially for individuals prone to acid reflux.

2. Dream Patterns:

  • Left Side: Sleep position, including left-side sleeping, may influence dream patterns. Individuals often report varied dream experiences depending on their chosen sleep posture.
  • Right Side: Similar to the left side, right-side sleeping may also contribute to diverse dream patterns, although individual experiences can vary.

Ayurvedic aspect of sleeping left side

Ayurveda, the traditional system of medicine in India, views the human body as an intricate balance of three doshas: Vata, Pitta, and Kapha. While Ayurveda does not explicitly prescribe sleeping on a specific side, it provides general guidelines for promoting overall health, including sleep. Here are some Ayurvedic aspects related to sleep:

  • Vata Dosha Balance:

Ayurveda suggests that the left side is associated with the calming and grounding qualities, which can help balance the Vata dosha. Vata is linked to movement and can become aggravated, leading to restlessness and sleep disturbances. Sleeping on the left side is believed to mitigate Vata-related issues.

  • Spleen and Stomach Position:

According to Ayurveda, sleeping on the left side places the stomach and spleen in a relatively lower position. This position is thought to promote the free flow of energy and fluids, aiding digestion and reducing the risk of acid reflux.

  • Lymphatic Drainage:

Ayurveda acknowledges the importance of lymphatic drainage for overall health. The left side sleeping position is said to support the body's natural lymphatic flow, helping in the removal of toxins and waste products.

  • Heart and Emotional Well-being:

Ayurvedic principles consider the left side as the side of the heart. While not specifically related to sleep, Ayurveda associates the left side with emotional well-being. Sleeping on the left side is thought to promote a sense of calmness and balance.

  • Pitta Dosha Considerations:

For individuals with a dominant Pitta dosha, Ayurveda may recommend avoiding excessive heat during sleep. Sleeping on the left side may help regulate body temperature, promoting a cooler sleep environment.

It's important to note that Ayurveda recognizes individual differences and emphasizes a holistic approach to health. While the left side sleeping position is mentioned in Ayurveda, personal comfort and specific health conditions should guide sleep choices.

Experts' Recommendations

Sleep specialists and orthopedic professionals offer valuable insights into the debate of left versus right sleep positions. Here's what the experts recommend:

1. Sleep Specialists:

  • Sleep specialists often emphasize the importance of individual comfort. There is no one-size-fits-all answer, and the best sleep position varies from person to person.
  • Factors such as existing health conditions, preferences, and comfort play a crucial role in determining the most suitable sleep position.

2. Orthopedic Views:

  • Orthopedic professionals highlight the significance of spinal alignment. Both left and right sleeping positions can be suitable, depending on the individual's spinal health and any existing back issues.
  • Using supportive pillows and mattresses is essential for maintaining proper spinal alignment, regardless of the chosen sleep position.

Hence, sleep quality is a multifaceted aspect influenced by various factors, including sleep position. Understanding how left and right positions impact deep sleep and dream patterns can guide individuals in making informed choices for a better night's rest. Consulting with sleep specialists and orthopedic experts can provide personalized recommendations based on individual health and comfort considerations.

Transitioning Between Positions

Changing sleep positions during the night is common, and understanding how to do so without disrupting your sleep is essential.

1. Effects on Sleep Continuity:

  • Frequent position changes can impact sleep continuity, leading to interruptions in your sleep cycle. It's advisable to find a position that allows you to remain comfortable for more extended periods.

2. Tips for Smooth Transition:

  • Slow Movements: When transitioning between positions, do so slowly and deliberately. Sudden movements may wake you up, disrupting the sleep cycle.
  • Pillow Adjustments: If changing from left to right (or vice versa), ensure your pillow adequately supports the new sleep position to maintain spinal alignment.
  • Comfort Experimentation: Experiment with different pillow and mattress combinations to find what works best for smooth transitions.

Pillow and Mattress Considerations:

Choosing the right pillow and mattress is as crucial as selecting the sleep position. Let's delve into the significance of proper support and how it contributes to a comfortable night's sleep.

1. Importance of Support:

  • Pillow Support: Regardless of your preferred sleep position, using a pillow that provides adequate support for your head and neck is vital. This helps maintain proper spinal alignment, reducing the risk of discomfort or pain.
  • Mattress Support: A supportive mattress is equally essential. It should offer proper spinal alignment and distribute body weight evenly to prevent pressure points.

2. Choosing the Right Pillow:

  • Left Side: For left-side sleepers, a medium-firm pillow that supports the head and neck without tilting them too far upward or downward is recommended.
  • Right Side: Right-side sleepers may benefit from a similar pillow, providing adequate support to maintain neutral spine alignment.

Sleep Disorders:

The relationship between sleep positions and certain sleep disorders is a necessary aspect to consider for a restful night. Let's explore how left and right sleeping positions may influence various sleep disorders and impact overall sleep health.

1. Relation to Sleep Positions:

  • Sleep Apnea: Individuals with sleep apnea may find certain sleep positions more conducive to managing their condition. For some, sleeping on the side, especially the left side, can reduce the severity of sleep apnea symptoms.
  • Snoring: Sleep positions can also influence snoring. Side sleeping, particularly on the left side, is often recommended to alleviate snoring as it keeps airways open.
  • Insomnia: For those dealing with insomnia, experts often recommend focusing on overall sleep hygiene rather than specific sleep positions. Creating a consistent sleep routine and a comfortable sleep environment can contribute to improved sleep.

Personal Preferences

While experts provide valuable insights, personal comfort, and preferences play a significant role in choosing the ideal sleep position.

1. Individual Comfort:

  • Unique Comfort Needs: Every individual is different, and what works for one person may not be suitable for another. Experiment with various sleep positions to discover what provides the most comfort and restful sleep for you.
  • Trial and Error: Don't hesitate to try different positions over time. It's normal for personal preferences to evolve, and your ideal sleep position may change.

2. Factors Influencing Choice:

  • Health Conditions: Consider any existing health conditions or concerns that may affect your sleep. Individuals with back pain may find certain positions more comfortable, while those with acid reflux may benefit from specific sleep postures.
  • Pregnancy: Pregnant individuals often have specific comfort needs, and the choice of sleep position may change throughout different stages of pregnancy.


In the debate of left vs. right sleeping positions, the conclusion is not a definitive answer but rather an acknowledgment of the individual nature of sleep preferences. The key is to find a balance that aligns with your comfort, health needs, and personal preferences.

While left-side sleeping may offer benefits such as improved digestion and reduced acid reflux, right-side sleeping could be advantageous for individuals dealing with heartburn. Both positions have their merits and drawbacks, highlighting the importance of individual variability.

Ultimately, the best sleep position is the one that allows you to wake up feeling refreshed and free of discomfort. Consider your unique health conditions, and personal comfort, and be open to experimentation. In the quest for a good night's sleep, remember that finding the right balance is a dynamic process that may evolve. Pay attention to your body's signals, embrace experimentation, and prioritize your sleep health for a consistently rejuvenating night's rest.
