Sleep paralysis is a parasomnia, or abnormal behaviour during sleep, that occurs when an individual is awake but temporarily unable to move or speak. It happens during the transition between sleep and wakefulness, either as one is falling asleep or upon waking up. Sleep paralysis is linked to the rapid eye movement (REM) stage of the sleep cycle, during which the eyes move quickly and vivid dreaming occurs, but the muscles of the body are relaxed to prevent acting out dreams. While sleep paralysis is generally benign and not harmful to health, it can be a frightening and distressing experience for those who encounter it. It is estimated that 7-20% of the general population experiences sleep paralysis at some point in their lives, with about 10% of people experiencing recurrent episodes. Recurrent sleep paralysis may be a symptom of a more serious problem, such as a sleep disorder or mental illness. Certain factors, including sleeping position, have been found to increase the likelihood of sleep paralysis. Sleeping on one's back may increase the chances of sleep paralysis occurring due to the position's association with airway obstruction, snoring, shallow breathing, and reduced blood circulation, which can contribute to disrupted REM sleep and micro-awakenings.

What You'll Learn
Back sleeping and snoring/sleep apnea
Sleep paralysis is a parasomnia, or abnormal behaviour that occurs during sleep. It is linked to the REM stage of the sleep cycle, during which the eyes move quickly and dreaming occurs, but the body's muscles are relaxed to prevent movement. During sleep paralysis, a person wakes up suddenly from REM sleep, regaining awareness while their muscles remain relaxed. This can result in temporary paralysis lasting from a few seconds to a few minutes. While sleep paralysis is not harmful to one's health, it can be a frightening experience.
Back sleeping and snoring:
Sleeping on your back can cause snoring, as this position allows the airway to collapse more easily. When the airway collapses, the resulting turbulent airflow during breathing causes the throat and nasal passages to vibrate, producing the sound of snoring. Back sleeping may also worsen snoring in overweight individuals, as excess fat deposits in the neck and throat can further constrict the airway. Additionally, alcohol consumption can exacerbate snoring in back sleepers, as it acts as a muscle relaxant, increasing the likelihood of airway collapse.
To alleviate snoring, individuals who sleep on their backs can try sleeping on their sides instead. Side sleeping reduces the likelihood of airway obstruction and has been shown to significantly decrease snoring intensity and duration. Elevating the head during sleep can also help open up nasal airway passages and reduce snoring.
Back sleeping and sleep apnea:
Sleep apnea is a condition characterised by pauses in breathing during sleep. It is associated with snoring, and 75% of people who snore have obstructive sleep apnea. Sleeping on the back can trigger sleep apnea by causing airway collapse, resulting in breathing cessations. Additionally, individuals with OSA who sleep on their backs may experience worsened symptoms due to gravity pulling the tongue and other tissues into a position where they block the airway.
To manage sleep apnea, individuals who sleep on their backs can try side sleeping or elevating their heads during sleep. Side sleeping reduces the likelihood of airway obstruction, thereby minimising breathing disruptions. Elevating the head can limit the effect of gravity on the tongue and other tissues, helping to keep the airway open. While sleeping on the back, using a pillow to elevate the head at a 60-degree angle may be sufficient to reduce breathing disruptions caused by sleep apnea.

Back sleeping and breathing difficulties
Sleep paralysis is a parasomnia, or abnormal behaviour, that occurs during sleep. It involves the temporary inability to move any part of your body, lasting from a few seconds to a few minutes, either right before falling asleep or as you wake up. It is often accompanied by hallucinations and a feeling of suffocation. While sleep paralysis is not harmful to your health, recurrent episodes may indicate an underlying sleep disorder or mental health condition.
Regarding the link between back sleeping and sleep paralysis, sleep experts have found a correlation between sleeping on your back and experiencing sleep paralysis. However, the exact mechanism behind this correlation is not yet clear. It is believed that sleep paralysis is caused by a disturbance in the rapid eye movement (REM) cycle, as it typically occurs during the transition into or out of REM sleep. During REM sleep, your brain normally paralyses your muscles to prevent you from acting out your dreams. However, during sleep paralysis, you regain awareness while your muscles remain relaxed, resulting in the temporary paralysis state.
Now, turning to the connection between back sleeping and breathing difficulties, there is a condition called orthopnea, which refers specifically to shortness of breath or difficulty breathing while lying down on your back. Orthopnea is characterised by sensations of breathlessness, tightness in the chest, and a feeling of being unable to catch your breath. It is important to note that orthopnea is typically a symptom of an underlying medical condition affecting the heart or lungs. Conditions such as heart failure, obesity, and respiratory issues can contribute to orthopnea. Treatment options include sleeping with the head propped up on pillows or sitting up, as changing body position can help alleviate the breathing difficulties associated with orthopnea.
Additionally, sleeping on your back has been linked to obstructive sleep apnea (OSA), a condition where breathing pauses during sleep due to narrowed or blocked airways. Sleeping on your back can contribute to OSA by causing the airway to become blocked or narrowed. Lifestyle changes, such as avoiding sleeping on your back, can help manage OSA symptoms.
In summary, while the direct connection between back sleeping and sleep paralysis requires further exploration, there is a clear association between the two. Additionally, back sleeping has been linked to breathing difficulties in conditions like orthopnea and OSA, where breathing issues are exacerbated when lying on the back. If you experience persistent or severe breathing difficulties while sleeping on your back, it is important to consult a healthcare provider for personalised advice and treatment options.

Back sleeping and micro-awakenings
Sleep paralysis is a parasomnia, or abnormal behaviour, that occurs during sleep. It is linked to the rapid eye movement (REM) stage of the sleep cycle, when the eyes move quickly and vivid dreaming occurs. During REM, the muscles of the body are relaxed to reduce movement, so people don't act out their dreams. This muscle relaxation is called REM atonia. Sleep paralysis occurs when someone wakes up suddenly from REM sleep, regaining awareness while their muscles are still relaxed.
Back sleeping is associated with a higher risk of sleep paralysis. Sleeping on your back can cause breathing difficulties, triggering micro-awakenings during REM sleep. These micro-awakenings may bring consciousness before muscle control is restored, resulting in sleep paralysis. When you sleep on your back, you may be more likely to be aroused from sleep or wake up during the dream phase due to snoring or undiagnosed obstructive sleep apnea.
During sleep paralysis, you are awake but temporarily unable to move or speak. You may experience hallucinations, chest pressure, and fear, which can make the episode feel more terrifying than it is. Sleep paralysis is not harmful, but it can be distressing, especially for those who experience it frequently.
If you experience sleep paralysis, you can try sleeping on your side to reduce susceptibility. You can also improve your sleep hygiene by getting adequate sleep, keeping a consistent sleep schedule, and creating an ideal sleep environment. It is also important to reduce distractions and avoid substances that can disrupt your sleep, such as caffeine, nicotine, and alcohol.

Back sleeping and disrupted REM sleep
Sleep paralysis is a parasomnia, or abnormal behaviour, that occurs during the rapid eye movement (REM) stage of the sleep cycle. During REM sleep, the eyes move quickly, and vivid dreaming occurs, while the muscles of the body are relaxed to prevent movement. Sleep paralysis occurs when an individual wakes up suddenly from REM sleep, regaining awareness while their muscles are still relaxed.
Back sleeping is associated with a higher risk of sleep paralysis. This is because sleeping on your back can cause breathing difficulties, triggering micro-awakenings during REM sleep. These awakenings may bring consciousness before muscle control is restored, resulting in sleep paralysis. Conditions such as undiagnosed obstructive sleep apnea (OSA) can also increase the likelihood of sleep paralysis in back sleepers, as snoring and sleep apnea can arouse individuals from sleep.
To reduce the risk of sleep paralysis, individuals who sleep on their backs can try sleeping on their sides instead. Placing pillows on either side of the body can also prevent individuals from rolling onto their backs during sleep.
In addition to back sleeping, sleep paralysis may be caused by disrupted sleep schedules, stress, substance use, and certain mental health conditions.

Improving sleep hygiene to prevent sleep paralysis
Sleep paralysis is a temporary phenomenon where an individual is conscious but unable to move or speak. It occurs when an individual suddenly regains awareness while exiting the REM sleep stage, during which the body is typically paralysed to prevent acting out dreams. While sleep paralysis is not harmful, it can be frightening and cause distress. Recurrent sleep paralysis may indicate an underlying condition, such as narcolepsy or mental health disorders.
Sleep experts have found a correlation between sleeping on your back and sleep paralysis. To reduce the likelihood of sleep paralysis, improving sleep hygiene is recommended. Here are some strategies to improve sleep hygiene and potentially prevent sleep paralysis:
Maintain a Consistent Sleep Schedule
Stick to a regular sleep schedule by going to bed and waking up at consistent times, even on weekends. This helps regulate your body's sleep-wake cycle and reduces the likelihood of sleep disruption.
Create a Conducive Sleep Environment
Ensure your bedroom is dark, cool, and quiet. Minimise distractions and create a relaxing atmosphere by avoiding the use of electronic devices before bed. Keep your phone, tablet, and other screens away at least an hour before bedtime.
Optimise Your Sleep Setup
Choose a mattress and pillow that suit your body's needs and provide comfort. A mattress that moulds to your body's pressure points, such as a memory foam mattress, can improve sleep quality. Select a pillow that keeps your neck and head in natural alignment, promoting proper spinal alignment during sleep.
Develop a Relaxing Bedtime Routine
Engage in relaxing activities before bed, such as taking a warm bath, reading, or listening to soothing music. These activities can help reduce stress levels and prepare your mind and body for sleep.
Experiment with Different Sleeping Positions
If you typically sleep on your back, try experimenting with different sleeping positions. Side sleeping or sleeping on your front may reduce the likelihood of sleep paralysis. Finding a comfortable position that works for you can improve sleep quality and reduce sleep disturbances.
Manage Stress and Substance Use
Stress and substance use can impact sleep quality. Try to minimise stress, especially before bedtime. Consider stress management techniques such as deep breathing or meditation. Additionally, curb substance use, especially in the evening. Avoid or reduce caffeine and alcohol intake, and steer clear of nicotine.
Seek Professional Help for Underlying Conditions
If you experience frequent sleep paralysis, consider consulting a healthcare professional. They can help identify and address any underlying sleep disorders, mental health conditions, or other medical problems that may be contributing to your sleep paralysis.

Frequently asked questions
During sleep, the body enters a state of temporary paralysis called REM atonia to prevent you from acting out your dreams. Sleep paralysis occurs when you wake up during this state, leaving you conscious but unable to move. Sleeping on your back can increase the likelihood of this happening due to airway obstruction, shallow breathing, and reduced blood circulation, which can cause micro-awakenings during REM sleep.
During an episode of sleep paralysis, you may be aware of your surroundings but unable to move or speak. Episodes often involve frightening hallucinations, such as sensing a dangerous presence or feeling chest pressure and suffocation. Sleep paralysis can last from a few seconds to a few minutes and usually ends when you are touched, spoken to, or moved.
Studies estimate that around 7% to 20% of people experience sleep paralysis at some point in their lives, with about 10% having recurrent episodes. Sleep paralysis usually begins in the teenage years and may become more frequent in the 20s and 30s.
To reduce the likelihood of sleep paralysis, it is recommended to improve sleep hygiene and maintain a consistent sleep schedule. This includes optimizing your sleep environment by keeping your bedroom dark, cool, and quiet, as well as reducing distractions from electronic devices before bed. Additionally, managing stress, avoiding substances like caffeine and alcohol, and treating underlying mental health conditions can also help prevent sleep paralysis.
