Sleeping on your chest, or sleeping on your stomach as it is more commonly known, can have several implications for your health. It is a fairly uncommon sleeping position, with only 7% of the population adopting it. While it may help alleviate sleep apnea and snoring, it can also cause neck or back pain. It can also cause or worsen acid reflux, a condition where stomach acid backflows into the oesophagus, resulting in a burning sensation in the chest. This position may also cause or exacerbate pleurisy, an inflammation of the thin layers covering the lungs, resulting in sharp chest pain.

What You'll Learn

It can cause restlessness and discomfort
Sleeping on your chest, or stomach sleeping, can cause restlessness and discomfort. It can be hard to get comfortable in this position, leading to tossing and turning throughout the night. This can be disruptive to your sleep quality and leave you feeling tired and unrested the next day.
Stomach sleeping can also cause strain on your neck, particularly if you use a pillow. This is because your neck is twisted to the side for the duration of your sleep, which can cause inflammation and pain in the neck muscles. This position can also lead to lower back pain. To avoid neck strain, it is recommended to use a very soft pillow or no pillow at all when sleeping on your stomach.
Sleeping on your chest can also be dangerous for people with certain health conditions. For example, it can worsen sleep apnea, a condition that causes pauses in breathing during sleep, by increasing the risk of heart failure. Sleep apnea can be exacerbated by sleeping on your back as well. If you have sleep apnea, it is recommended that you sleep on your side.
Additionally, chest pain at night can be a symptom of underlying health issues such as gastrointestinal issues, acid reflux, or heart problems. If you are experiencing chest pain at night, it is important to speak to a doctor to determine the cause and receive proper treatment.

It may lead to neck and back pain
Sleeping on your chest, or front, can cause neck and back pain. This is because the position strains your neck and lower back. The turning of the head to one side when sleeping on your chest can cause inflammation and pain in the neck muscles, as well as back pain. This is due to the increased workload placed on the spine, which can also result in pain and swelling at the shoulders.
Sleeping in the fetal position, which involves bowing the head forward, arching the back, bending at the hips, and flexing at the knees, can also cause inflammation and pain in the lower back due to the back's curvature. This position stretches and tightens the back muscles.
Sleeping on your side or back are considered healthy sleeping positions. If you sleep on your back, your legs are usually stretched out in a neutral pose, and your arms are flat by your sides, bent with your hands across your chest or stomach, or raised above your shoulders with your hands by your face. Sleeping on your side can be made more comfortable with a pillow to support your body.
If you sleep on your chest, you may want to use a very soft pillow or no pillow at all to keep your neck comfortable.

It could worsen acid reflux
Sleeping on your chest, or front, is not recommended due to the potential health issues it can cause or exacerbate. One of the main issues is acid reflux, which tends to worsen when lying down as it is common to feel chest pressure due to the condition. Sleeping on your chest can also cause or worsen neck and back pain, and can lead to inflammation and pain in the neck muscles. This is because sleeping on your front can strain your neck and lower back, and the turning of the head to one side can cause curvature in the spine, leading to further pain and swelling in the shoulders and lower back.
If you must sleep on your chest, it is advised to do so for only short periods, and to use a pillow underneath the chest or abdomen to increase comfort. Additionally, to help combat chest pain caused by acid reflux, it is recommended to avoid eating or drinking alcohol before bed and to refrain from consuming spicy foods. Sleeping on your left side has also been found to be the best position to reduce the exposure of the oesophagus to stomach acid.
Acid reflux occurs when stomach acid flows back into the food pipe, causing a burning sensation in the chest and throat. This can be caused by a variety of factors, including diet, obesity, and certain medications. Sleeping on your chest can worsen acid reflux because it allows the stomach acid to flow more easily back up into the oesophagus. This can lead to increased chest pain and discomfort, as well as a higher risk of developing more serious complications such as oesophageal cancer.
In addition to worsening acid reflux, sleeping on your chest can also put pressure on internal organs, such as the heart and lungs, which can restrict blood flow and breathing. This can be particularly dangerous for people with heart or lung conditions, or for pregnant women, as it can affect the fetus' blood flow. Sleeping on the chest can also increase the risk of developing sleep apnea, a condition that causes pauses in breathing during sleep, which can lead to an increased risk of heart failure if left untreated.
Overall, while sleeping on your chest may be comfortable for some people, it is important to be aware of the potential health risks, especially for those with pre-existing conditions. It is recommended to sleep on the side or back, with a pillow that offers suitable height and support, to reduce the risk of worsening acid reflux and other health issues.

It may not be suitable for pregnant people
Sleeping on your chest, also known as sleeping on your stomach, is not recommended for pregnant people. While there is no strong scientific link between sleep positions and back pain, sleeping on your chest can cause restlessness and discomfort, especially if you already have back pain. This position can also strain your neck and lower back.
Pregnant people should be particularly mindful of their sleep position. Sleeping on your back during late pregnancy (28 weeks or later) has been linked to adverse pregnancy outcomes, such as stillbirth and low birth weight. Research has shown that sleeping on your back is generally okay early in pregnancy, but as the pregnancy progresses, it is best to sleep on your side. Side sleeping helps maintain the curve in your back and puts less pressure on your inferior vena cava and abdominal aorta.
If you experience any warning signs of pregnancy complications, such as breathing problems, chest pain, dizziness, severe nausea, or severe swelling in the hands or face, it is important to seek medical care immediately.
While sleeping on your chest may not be suitable for pregnant people due to the discomfort and potential strain on the neck and back, sleeping on your back during late pregnancy should also be avoided to lower the risk of adverse outcomes.

It could increase the risk of bone, muscle, or nerve injuries
Sleeping on your chest can increase the risk of bone, muscle, or nerve injuries. Sleeping in this position can cause neck and back pain. This is due to the strain placed on the neck as it is turned to one side, which can lead to inflammation and pain in the neck muscles. Similarly, sleeping on your chest can also cause lower back pain due to the unnatural curvature of the spine. This can result in tight and inflamed back muscles.
The fetal position, which involves bowing the head forward, arching the back, bending at the hips, and flexing at the knees, is particularly unhealthy for similar reasons. Sleeping in this position for extended periods can cause knee pain as the ligaments around the knees and hips become inflamed due to constant flexion. It can also cause inflammation and pain in the lower back due to the unnatural curvature of the spine, which stretches and tightens the back muscles.
Sleeping on your chest can also cause or exacerbate existing injuries to the chest wall. Any type of movement of the torso can cause pain if the muscles and bones of the chest wall have been strained or injured. Therefore, sleeping on your chest may aggravate these injuries and cause further discomfort.
To reduce the risk of bone, muscle, or nerve injuries, it is recommended to sleep in healthy sleeping positions, such as on your side or back. These positions provide better support for the body and reduce strain on the neck, back, and chest. Additionally, using suitable bedding, such as a pillow that offers the correct height and a mattress that provides adequate back support, can also help prevent injuries and improve sleep quality.
