What You'll Learn
Supine sleeping may reduce facial wrinkles
The supine position refers to lying horizontally on one's back, with the face and torso facing upwards. It is a common position for sleep, yoga, Pilates, and other forms of exercise.
While there is no universally "best" sleeping position, and personal preference, age, health, and comfort all play a role in determining the most suitable sleep posture, sleeping in the supine position may offer certain benefits and drawbacks.
One potential advantage of supine sleeping is the reduction of facial wrinkles. Sleeping on the stomach or side can compress the skin and contribute to wrinkle formation, whereas sleeping on the back minimizes facial compression and may help maintain skin elasticity and reduce the appearance of wrinkles over time.
In addition to its potential cosmetic benefits, supine sleeping is also believed to be beneficial for lower back pain. This position can ease tension in the neck, shoulders, and back, promoting a neutral spine alignment and reducing pressure on the bones and muscles.
However, supine sleeping may also carry some risks and disadvantages. It can worsen gastroesophageal reflux disease (GERD) as it allows stomach acid to travel up the esophagus and remain there for longer. Additionally, this position has been linked to an increased risk of snoring and obstructive sleep apnea (OSA) due to the downward position of the tongue and jaw, which can crowd the airway and reduce lung volume. For pregnant women, sleeping in the supine position after 24 weeks of pregnancy may cause dizziness and breathing difficulties, and it can also increase the risk of stillbirth by compressing the inferior vena cava, reducing blood flow to the uterus, and causing low blood pressure. Furthermore, a 2019 study suggested a link between increased time sleeping in the supine position and a higher rate of neurodegenerative diseases, although more research is needed to confirm this connection.
Overall, while supine sleeping may offer certain benefits, such as the potential reduction of facial wrinkles and relief from lower back pain, it is important to consider individual health conditions and preferences when choosing a sleeping position, as there are both advantages and drawbacks to sleeping in this posture.

It can worsen reflux
The supine position refers to lying flat on the back, with the face pointing upward. While this is a common sleeping position, it can cause issues for people with acid reflux.
When lying down, gravity is no longer able to help keep stomach acid in the stomach. This means that acid can flow more easily into the oesophagus, causing heartburn. Sleeping on the left side is recommended for people with acid reflux, as it helps to reduce reflux episodes and exposure of the oesophagus to stomach acid. Sleeping on the right side can make reflux worse. Elevating the upper body can also help to prevent reflux, as it stops the throat and stomach from being at the same level.
In addition, saliva production, which usually helps to neutralise stomach acid, is reduced during deeper stages of sleep. With less saliva, and decreased swallowing during sleep, stomach acid is pushed downward less, which can lead to acid leaking into the oesophagus. This can cause more severe symptoms of gastroesophageal reflux disease (GERD), which may disturb sleep.
GERD can also disrupt sleep with nighttime acid reflux symptoms. Reflux tends to worsen when lying down, and sleeping in the supine position can make reflux more likely. This is because the diaphragm and abdominal organs may compress the adjacent lung when shifting from standing to supine, reducing lung volume. This can decrease overall sleep quality.

It may increase snoring
Sleeping in the supine position, or sleeping on your back with your face pointing upward, may increase snoring. This is because sleeping in the supine position can lead to sleep-related breathing problems, including obstructive sleep apnea (OSA). OSA is a form of sleep apnea that occurs when throat muscles relax and collapse during sleep, causing pauses in breathing. It is most severe when individuals are sleeping in the supine position, as their ability to increase lung volume and expand the chest may be compromised.
According to the Journal of Clinical Sleep Medicine, the supine sleeping position can increase snoring. Additionally, research suggests that sleeping in the supine position plays a role in more than half of all cases of OSA. OSA affects 75% of people who snore and increases the risk of developing heart disease. For this reason, many healthcare providers encourage patients with OSA to avoid sleeping in the supine position and instead sleep laterally or with their head elevated on a pillow at a 30- or 45-degree angle.
Furthermore, sleeping in the supine position can cause or aggravate back and neck pain, making it more difficult to sleep comfortably and potentially increasing snoring. While sleeping on the back is recommended for lower back pain, it can worsen neck pain and cause the back to arch uncomfortably. To alleviate this, individuals can place pillows under their knees to encourage a flatter back.
Sleeping in an inclined position has been shown to reduce snoring and improve sleep quality. A study on self-reported snorers found that sleeping with the upper body inclined at a 12-degree angle reduced snoring duration by 7% and improved sleep quality. The participants also reported being woken up by their snoring less often, indicating that sleeping in an inclined position can benefit both the snorer and their bed partner.

It can cause breathing problems for people with OSA
Sleeping in the supine position, also known as sleeping on your back, can have implications for respiratory health, particularly for individuals suffering from obstructive sleep apnea (OSA). OSA is a condition characterized by repeated episodes of partial or complete blockage of the upper airway during sleep, resulting in disrupted breathing and poor sleep quality. When an individual with OSA sleeps in the supine position, the force of gravity can exacerbate the collapse of the soft tissues in the throat, including the tongue and palate, which can obstruct the airway and lead to apnea (cessation of breathing) episodes.
The supine sleeping position can cause breathing problems for people with OSA due to the way it affects the body's airway dynamics. When an individual sleeps on their back, the tongue and soft palate can fall back towards the throat, narrowing the airway and increasing air velocity. This increased air velocity can then cause the soft tissues to vibrate and eventually collapse, blocking the airway and leading to apnea events. Additionally, sleeping supine can promote a more kinked airway position, further restricting airflow and exacerbating breathing difficulties for OSA sufferers.
The effects of gravity on the airway are particularly pronounced in the supine position. Without the support of the mattress and pillow, the weight of the head and neck can exert additional pressure on the airway, narrowing the passage and increasing the likelihood of obstruction. This gravitational effect can be more pronounced in individuals with excess weight or obesity, as the presence of excess tissue in the neck and throat can further compromise the airway, making it more susceptible to collapse when sleeping on the back.
For people with OSA, the supine sleeping position can lead to a higher frequency and severity of apnea events, resulting in disrupted sleep and a range of associated health complications. These breathing interruptions can cause frequent awakenings, leading to non-restorative sleep and daytime fatigue. Additionally, OSA has been linked to an increased risk of cardiovascular disease, hypertension, type 2 diabetes, and cognitive impairment, among other conditions. Therefore, it is crucial for individuals with OSA to be aware of the impact of their sleeping position and to consider measures to avoid sleeping supine.
To mitigate the breathing problems associated with OSA when sleeping supine, individuals may benefit from positional therapy techniques. This can include the use of specialized pillows or body pillows that provide support and encourage side sleeping. Sleeping with an elevated head and upper body can also help counteract the effects of gravity on the airway. In some cases, a supine avoidance device may be recommended to provide tactile feedback and discourage back sleeping. It is important for individuals with OSA to consult with a sleep specialist to determine the most appropriate treatment options, which may include positional therapy, continuous positive airway pressure (CPAP) therapy, or other interventions.
Overall, the supine sleeping position can significantly impact the respiratory health of individuals with OSA by increasing the likelihood of airway obstruction and apnea events. Understanding the implications of sleeping on the back is essential for managing OSA effectively and improving overall sleep quality and health outcomes. Positional therapy techniques and other interventions can help individuals with OSA avoid the supine position and breathe more easily during sleep.

It's beneficial for back pain
Sleeping in the supine position—lying flat on your back with your face up—offers several benefits for those experiencing back pain. This sleeping posture helps maintain a neutral spine alignment, which can be particularly advantageous for individuals with back pain. Here's how sleeping supine can help alleviate and prevent further discomfort:
Spinal Alignment and Pressure Relief: Sleeping on your back allows for even weight distribution along your spine. This neutral position helps reduce pressure on certain points along the spine, which can be beneficial if you suffer from lower back pain. When you lie supine, the mattress supports the natural curvature of your spine, helping to alleviate pain and tension.
Relaxed Neck and Shoulders: The supine position can also help relax the neck and shoulders, which often carry a lot of tension and contribute to back pain. By keeping your head and neck in a neutral position, you avoid adding extra strain to these areas. Using a thin pillow or no pillow at all when sleeping supine can further enhance this benefit, ensuring that your neck remains in a comfortable, relaxed position.
Reduced Risk of Nerve Compression: Sleeping on your back helps prevent nerve compression, especially in the lumbar region. When you lie on your back, there is less chance of a nerve becoming pinched or irritated, which can cause or exacerbate back pain. This is especially beneficial for those suffering from conditions like sciatica, where nerve compression can lead to significant pain and discomfort.
Improved Posture: Sleeping supine can contribute to improved posture during the day. This position helps train your body to maintain a straight spine and aligned pelvis, which can reduce back pain caused by poor posture. Over time, you may find that sleeping supine carries over into your daily activities, encouraging better posture when standing or sitting, leading to reduced back discomfort overall.
Optimal Mattress Support: To maximize the benefits of sleeping supine for back pain relief, ensure you have a mattress that provides adequate support. A medium-firm to firm mattress is generally recommended for back pain sufferers. This level of firmness offers enough support to maintain spinal alignment while still providing comfort and pressure relief.
By adopting the supine sleeping position and pairing it with the right mattress, those with back pain can find relief and improve their overall spinal health. It is important to note that while sleeping on your back offers these advantages, comfort is also key to a good night's rest. If you find the supine position uncomfortable, you can try placing a pillow under your knees to provide additional support and help maintain spinal alignment.
