Sleep apnea is a common condition that affects millions of Americans and can lead to serious health complications if left untreated. It occurs when a person's airway becomes blocked during sleep, causing them to stop breathing for brief moments throughout the night. This can result in poor sleep quality and daytime fatigue, as well as more severe issues like high blood pressure and chronic heart failure. The good news is that obstructive sleep apnea (OSA) can often be managed through positional therapy, which involves sleeping in certain positions that help to keep the airways open and reduce breathing disruptions. Side sleeping, for example, is generally recommended for people with OSA as it can help to alleviate mild apnea and reduce snoring. Sleeping on the left side can also help with acid reflux, while the right side may be better for enhancing airway openness. Pregnant women are encouraged to sleep on their left side to improve circulation to the fetus. In contrast, sleeping on the back is often considered the worst position for people with OSA, as it can obstruct the airway and worsen symptoms.

What You'll Learn
Sleeping on your back can worsen OSA
Obstructive Sleep Apnea (OSA) occurs when the airway becomes narrowed or blocked during sleep, causing interruptions to breathing. OSA is the more common form of sleep apnea, affecting around 22 million Americans. It is caused when the muscles and tissues in the throat become overly relaxed and impede the airway. Snoring often accompanies OSA due to tissue vibration. OSA can also cause morning headaches, jaw pain, and stiff necks.
Sleeping on your back can make OSA worse because it increases the likelihood of these airway blockages. When individuals sleep on their backs, the tissues in the upper airway (including the tongue, adenoids, and uvula) are more likely to crowd the back of the throat and create upper airway resistance. This can lead to pauses in breathing and a drop in oxygen levels, resulting in poor sleep quality and daytime fatigue.
Research has shown that sleeping on your side can significantly reduce breathing disruptions from OSA. Side sleeping helps to keep the airways open and prevents the tissues in the mouth and throat from blocking the airway. This is why many doctors recommend side sleeping as part of a plan to address OSA. Sleeping on the left side is often recommended, as it can improve blood flow, reduce pressure on key blood vessels, and alleviate gastric conditions such as GERD and acid reflux, which can contribute to sleep apnea. However, some evidence suggests that right-side sleeping may be better for individuals with OSA, as it reduces the risk of airway obstruction and improves snoring.

Side sleeping is the most recommended position for OSA
Side sleeping is the most recommended position for managing OSA. This is because it is effective in maintaining open airways and reducing snoring, which is often a symptom of OSA.
OSA, or obstructive sleep apnea, occurs when the airway shuts or becomes obstructed during sleep. This happens when the muscles and tissues in the throat become overly relaxed and impede the airway. Snoring often accompanies OSA because of tissue vibration.
Sleeping on your side helps to keep the airways open and reduces the likelihood of tissues in your mouth and throat blocking your airway. For this reason, many doctors recommend side sleeping as part of a plan to address OSA.
Research shows that sleeping on your right side is the best position for reducing OSA, likely due to differences in blood flow to and from the heart. However, left-side sleeping may be more appropriate under certain circumstances. For example, if you have gastroesophageal reflux disease (GERD) or are pregnant, sleeping on your left side can help alleviate symptoms.
If you are a back sleeper, you can exacerbate OSA as gravity pulls down on the tongue and throat tissues, leading to airway obstruction.

Sleeping on your left side is better for acid reflux
Sleeping on your side is widely regarded as the best position for reducing obstructive sleep apnea (OSA). This is because, when sleeping on your side, the tissues in your mouth and throat are less likely to block your airway. However, the optimal sleeping position for OSA is on your right side, as this position aids in pulling the diaphragm downward, enhancing airway openness.
On the other hand, sleeping on your left side is better for acid reflux. This is because the esophagus enters the stomach from the right, so sleeping on the left side keeps acid down through gravity. This position also keeps the junction between the stomach and esophagus above the level of gastric acid, allowing acid to exit the esophagus more quickly.
Several studies have supported the claim that left-side sleeping reduces acid reflux. One study, published in the Journal of Clinical Gastroenterology, found that the "total amount of reflux time was significantly greater" when subjects lay on their right side. Another study, published in the American Journal of Gastroenterology, monitored 57 people with chronic heartburn during sleep. The study found that acid cleared much faster when participants were on their left side, as opposed to their back or right side.
In addition to sleeping on your left side, there are other ways to reduce acid reflux. These include elevating your upper body with a wedge pillow, avoiding meals close to bedtime, and taking heartburn medications.

Stomach sleeping can reduce the severity of OSA
Sleep position can play a role in the severity of obstructive sleep apnea (OSA). OSA is a common sleep disorder that causes breathing to stop for short periods throughout the night, depriving the brain of oxygen. Untreated, OSA can lead to serious health conditions such as high blood pressure, heart disease, stroke, diabetes, and obesity.
Stomach sleeping is one of the rarest sleep positions, with only about 7% of people sleeping this way. However, it can be an effective way to reduce the severity of OSA. Sleeping on your stomach helps improve oxygen saturation (the amount of oxygen in your blood) and reduces the apnea-hypopnea index (AHI), a measure of sleep apnea severity. It also decreases the chance of soft tissues in the mouth and throat blocking airflow.
For those who use a continuous positive airway pressure (CPAP) machine to treat their OSA, stomach sleeping is still a viable option. Nasal pillow masks are the most appropriate option for stomach sleepers, as they are small, light, and low-profile, providing maximum comfort and minimal face contact. Full-face masks with top-of-the-head tubing are another option, allowing for stomach sleeping without tubing pressing into the face or being dislodged by the pillow.
To optimize comfort and support for your neck and spine while stomach sleeping, it is recommended to use a thin pillow. The goal is to keep your spine in its natural alignment and prevent any strain.
While stomach sleeping can help reduce OSA severity, side sleeping is generally recommended for OSA. Side sleeping prevents gravity from interfering with airways, reducing breathing disruptions and snoring. Sleeping on the left side is often recommended for additional benefits, such as alleviating acid reflux and promoting healthy blood flow.

Sleeping on your right side is better for certain heart conditions
Sleeping position can play a role in both types of sleep apnea: Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA). OSA occurs when a narrowed or blocked airway interferes with breathing during sleep, while CSA occurs when the brain fails to send the signals required for normal breathing. Side sleeping is generally recommended for reducing sleep apnea symptoms, as it helps to keep the airways open.
Now, when it comes to the idea that sleeping on your right side is better for certain heart conditions, there are a few things to consider. Firstly, it's important to note that the relationship between sleep position and heart health is not fully understood, and more research is needed. While sleeping position may not have a significant impact on heart health for most people, it can play a role for those with certain chronic conditions.
Some studies suggest that sleeping on the left side may lead to changes in heart and lung function, particularly for individuals with congestive heart failure. People with heart failure often experience shortness of breath, which can worsen when sleeping on the left side, leading many to prefer sleeping on their right side. Additionally, sleeping on the right side may keep the fetus' weight from applying pressure to the inferior vena cava, improving blood flow to the fetus during pregnancy.
On the other hand, sleeping on the left side may be beneficial for individuals with gastroesophageal reflux disease (GERD) or acid reflux, as it helps with acid clearance and keeps acid down through gravity. However, it's important to note that left-side sleeping may have negative effects on the heart for some individuals.
In summary, while sleeping on your right side may be preferable for certain heart conditions, such as heart failure, the overall influence of sleeping position on heart health is not fully understood. More research is needed to determine the specific effects of different sleeping positions on heart health.

Frequently asked questions
Obstructive Sleep Apnea (OSA) is a sleep disorder that occurs when the airway shuts or becomes blocked during sleep due to overly relaxed throat muscles and tissues. This can cause breathing interruptions up to 10 seconds long that can occur as many as 30 times an hour.
Sleeping on your back can make OSA worse as gravity pulls the tongue and throat tissues down, blocking the airway. Side sleeping is generally recommended for OSA as it helps to keep the airway open and reduces snoring. Sleeping on your stomach can also help to reduce OSA symptoms by pulling the tongue and surrounding soft tissue away from the airway.
Most sources recommend sleeping on your side, particularly the left side, to reduce OSA symptoms. However, sleeping on your right side can be more comfortable for those with certain heart conditions. If you are a stomach sleeper, be sure to turn your head to the side to allow room for breathing.
