Rem Sleep Paralysis: What, Why, And How?

Sleep paralysis is a common phenomenon, with an estimated 30% of people experiencing it at least once in their lifetime. It occurs when you're stuck between sleep phases, either right before falling asleep or upon waking up. During this temporary episode, you're aware of your surroundings but unable to move or speak, although your eyes can still move and you can breathe. Sleep paralysis can be a frightening experience, often causing feelings of anxiety and confusion. While there is no treatment to stop an episode once it starts, certain measures can be taken to reduce its frequency. Interestingly, research has discovered that two powerful brain chemical systems work together to paralyze skeletal muscles during REM sleep, which is the stage of sleep where most dreams occur.

REM sleep is the deep sleep phase where most recalled dreams occur

Sleep paralysis is a normal part of REM sleep. During REM sleep, our eyes continue to move, but the rest of the body's muscles are stopped, which prevents us from acting out our dreams. This is known as muscle atonia. Two powerful brain chemical systems work together to paralyze skeletal muscles during REM sleep: the neurotransmitters gamma-aminobutyric acid (GABA) and glycine. These neurotransmitters switch off the specialized cells in the brain that allow muscles to be active.

Sleep paralysis occurs when a person becomes aware as the body enters or exits REM sleep. It can last from a few seconds to a few minutes, and it can be a frightening experience. During an episode, a person is aware of their surroundings but cannot move or speak. They may feel scared or anxious, and may even hallucinate. Sleep paralysis is usually temporary and harmless, but it can cause emotional distress. It has been linked to factors such as stress, sleep deprivation, and mental health conditions.

While there is no treatment to stop a sleep paralysis episode once it's occurring, there are ways to reduce the frequency of episodes. These include improving sleep hygiene, maintaining a consistent sleep schedule, and creating a comfortable sleep environment. Additionally, seeking treatment for any underlying mental health conditions or sleep disorders can help.

Brain chemical systems work together to paralyze skeletal muscles during REM sleep

During REM sleep, the deep sleep where most recalled dreams occur, the eyes continue to move but the rest of the body's muscles are stopped, potentially to prevent injury. According to research by the University of Toronto, two powerful brain chemical systems work together to paralyze skeletal muscles during REM sleep. The neurotransmitters gamma-aminobutyric acid (GABA) and glycine cause REM sleep paralysis by "switching off" the specialized cells in the brain that allow muscles to be active.

This finding reversed the earlier belief that glycine was a lone inhibitor of these motor neurons. The researchers found that to prevent REM sleep paralysis, they had to block both the ionotropic receptors and metabotropic GABAB receptors, a different receptor system. In other words, when the motor cells were cut off from all sources of GABA and glycine, the paralysis did not occur, and the rats exhibited high levels of muscle activity when their muscles should have been inactive. The data suggest that the two neurotransmitters must both be present together to maintain motor control during sleep, rather than working separately.

The findings of this study may help scientists better understand and treat sleep disorders, including narcolepsy, tooth grinding, and REM sleep behavior disorder. Furthermore, it could be especially helpful for those with REM sleep disorder, a disease that causes people to act out their dreams, which can cause serious injuries to patients and those around them.

Sleep paralysis is temporary and can last from a few seconds to 20 minutes

Sleep paralysis is a temporary condition that can last from a few seconds to a couple of minutes, with some episodes lasting up to 20 minutes. During an episode, a person is unable to move or speak while falling asleep or waking up. While the exact cause of sleep paralysis is not fully understood, it is believed to be linked to various factors, such as sleep deprivation, irregular sleep schedules, and certain medical conditions.

Episodes of sleep paralysis typically occur when an individual is stuck between sleep phases, particularly during the transition from the REM (rapid eye movement) sleep stage to wakefulness. During REM sleep, the body is in a state of paralysis to prevent movement during dreams and protect against self-injury. However, during sleep paralysis, the brain has awoken while the body remains in REM mode, resulting in a temporary inability to move.

The length of a sleep paralysis episode can vary significantly, ranging from a few seconds to a couple of minutes. In rare cases, episodes can last up to 20 minutes. The duration of an episode often depends on external factors, such as being touched or moved, which can help end the paralysis.

While sleep paralysis itself is not dangerous, it can cause emotional distress and anxiety during and after an episode. The experience of being unable to move or speak can be frightening and may lead to confusion when movement returns. Additionally, individuals may experience hallucinations or dream-like sensations, further intensifying the emotional impact of the episode.

It is important to note that sleep paralysis is a common occurrence, with an estimated 30% of people worldwide experiencing at least one episode in their lifetime. While there is no treatment to stop an episode once it starts, treatments are available to reduce the frequency of episodes. These treatments often focus on improving sleep habits and addressing any underlying sleep disorders or mental health conditions.

Sleep paralysis can be treated by improving sleep hygiene and addressing underlying mental health conditions

Sleep paralysis is a frightening but common phenomenon, with an estimated 30% of people experiencing at least one episode in their lifetime. It is not usually dangerous but can cause emotional distress and anxiety. Sleep paralysis occurs when you are conscious but unable to move or speak as you are falling asleep or waking up. This temporary paralysis happens when you are between sleep phases, usually as you are entering or exiting the REM sleep phase. During REM sleep, your brain normally paralyses your muscles so that you don't act out your dreams. However, during sleep paralysis, your mind is awake, or half-awake, and you are aware that you cannot move.

Improving Sleep Hygiene

• Get adequate sleep: Aim for 7-9 hours of sleep per night consistently.
• Maintain a consistent sleep schedule: Go to bed and wake up at the same times every day, even on weekends.
• Create a comfortable sleep environment: Ensure your bedroom is dark, cool, and quiet.
• Use suitable bedding: Choose a mattress and pillow that suit your body's needs and keep your neck and head in natural alignment.
• Reduce distractions: Avoid using electronic devices before bed. Put away phones, tablets, e-readers, and computers at least an hour before bedtime.
• Relax before bed: Engage in relaxing activities such as taking a bath, reading, or listening to soothing music to help you unwind.
• Avoid substances: Curb your intake of caffeine, alcohol, and nicotine, especially in the evening.
• Try new sleeping positions: If you sleep on your back, consider trying different positions. Sleep experts have found a correlation between sleeping on your back and sleep paralysis.
• Manage stress: Do what you can to ease stress in your life, especially before bedtime.

Addressing Underlying Mental Health Conditions

• Seek professional help: If you experience frequent stress, anxiety, or other mental health concerns, consider talking to a mental health provider. Cognitive behavioural therapy could help you manage stress and anxiety.
• Treat underlying conditions: If you have an underlying mental health condition, such as anxiety, depression, bipolar disorder, PTSD, or panic disorder, work with your doctor to oversee your ongoing treatment. Treating these conditions may help resolve sleep paralysis.

By implementing these strategies and addressing any underlying mental health concerns, you can effectively manage sleep paralysis and improve your sleep quality.

Sleep paralysis is a normal part of REM sleep but is considered a disorder when it occurs outside of it

Sleep paralysis is a temporary condition where you are unable to move right before falling asleep or upon waking up. It occurs when your body is stuck between sleep phases, usually during the REM stage of sleep. While it is a normal part of REM sleep, it is considered a disorder when it happens outside of REM sleep.

During REM sleep, the body is in a state of deep sleep where most recalled dreams occur. The eyes continue to move, but the rest of the body's muscles are paralysed, likely to prevent injury from acting out dreams. This paralysis is caused by two powerful brain chemical systems that work together to paralyse skeletal muscles. Specifically, the neurotransmitters gamma-aminobutyric acid (GABA) and glycine "switch off" the specialised cells in the brain that allow muscles to be active.

Sleep paralysis can be a frightening experience, leaving individuals feeling scared, anxious, or confused. It is often accompanied by vivid hallucinations, such as sensing a dangerous presence or feeling out of one's body. However, it is not typically dangerous and can be managed by improving sleep quality and treating underlying conditions.

While there is no treatment to stop sleep paralysis during an episode, it can be managed and reduced in frequency. Treatment options include medications that prevent individuals from reaching the REM stage of sleep, addressing underlying mental health or sleep disorders, and improving sleep hygiene. Additionally, focusing on making small body movements, such as wiggling a finger or toe, can help break the paralysis.

Sleep paralysis is a common occurrence, with an estimated 30% of people worldwide experiencing at least one episode in their lifetime. It can affect people of all ages and is more frequent in individuals with varying sleep schedules or those experiencing high levels of stress.
