If you or your bed partner are experiencing thrashing in sleep, it may be a cause for concern. While occasional movements during sleep are normal, constant and violent movements may indicate an underlying sleep disorder or health condition. Sleep disorders such as REM sleep behavior disorder (RBD), sleep apnea, and restless legs syndrome (RLS) can cause thrashing in sleep. If you are experiencing disruptive sleep or daytime fatigue, it is recommended to consult a doctor and consider a sleep study for a detailed analysis. Treatments and lifestyle changes, such as regular exercise and reduced caffeine intake, can help improve sleep quality.

Parasomnias: sleep disorders characterised by disruptive behaviours or events
Parasomnias are disruptive sleep disorders characterised by abnormal behaviours or events during sleep. They can occur as you fall asleep, during sleep, or just before you wake up. There are three main groups of parasomnias, classified according to the sleep stage they affect: non-rapid eye movement (non-REM), rapid eye movement (REM), and others that do not fit into either category. Non-REM sleep parasomnias involve physical and verbal activity, while REM sleep parasomnias are characterised by vivid dreams and the physical and/or vocal enactment of dreams.
Parasomnias can manifest in various ways, including sleepwalking (somnambulism), sleep terrors, and confusional arousals. Sleepwalking episodes may involve getting out of bed and performing complex activities such as driving or playing an instrument, and the sleeper's eyes may be wide open, yet they remain asleep. Sleep terrors are characterised by sudden awakenings accompanied by fear, screaming, crying, a racing heart rate, dilated pupils, fast breathing, and sweating. These episodes typically last from 30 seconds to a few minutes. Confusional arousals are marked by feelings of confusion and disorientation upon waking, with possible symptoms including open eyes, slow speech, and emotional expressions such as crying. This type of parasomnia is more common in childhood and tends to decrease with age.
Another type of parasomnia is REM Sleep Behaviour Disorder (RBD), which occurs during the REM stage of sleep. Individuals with RBD physically act out their dreams, sometimes resulting in harm to themselves or their bed partners. The underlying cause of RBD is not fully understood, but it is believed to be associated with the temporary paralysis that typically occurs during REM sleep. Obstructive sleep apnea (OSA) can mimic RBD symptoms, and treating OSA can help eliminate these behaviours. Medications such as melatonin, clonazepam, and pramipexole are also used to treat RBD.
Parasomnias can significantly impact an individual's sleep quality and daily functioning. If you or your bed partner notice disruptive sleep behaviours, it is important to consult a doctor and consider a sleep study for a detailed evaluation. Lifestyle modifications, such as regular exercise, weight loss, caffeine and alcohol reduction, and stress management, can also help improve sleep quality and reduce parasomnia symptoms.

REM sleep behaviour disorder: acting out dreams during REM sleep
There are several possible causes of thrashing in sleep, one of which is REM sleep behaviour disorder (RBD). RBD is a sleep disorder in which a person physically acts out their dreams while in the rapid eye movement (REM) stage of sleep. This occurs because the body does not experience the normal temporary muscle paralysis, or atonia, that usually happens during the REM stage. This allows the person to make physical and vocal movements, such as shouting, punching, kicking, and jumping out of bed, that correspond to what is taking place in their dream. The symptoms of RBD can vary in severity, and people with this disorder are often unaware of their behaviours during sleep.
RBD is characterised as a parasomnia, which is a type of sleep disorder characterised by abnormal behaviours during sleep that disrupt sleep. Parasomnias can occur during the non-REM or REM sleep phase and can include physical and verbal activity, such as sleepwalking, sleep terrors, and sleep paralysis. Sleepwalking, or somnambulism, involves getting out of bed and moving about with eyes open, but while remaining asleep. The person may perform complex activities or unusual behaviours, such as driving or playing a musical instrument. Sleep terrors involve waking up suddenly feeling scared and can include screaming or crying, a racing heart rate, dilated pupils, fast breathing, and sweating. Sleep paralysis is when a person wakes up and is unable to move.
If you or your partner are experiencing symptoms of RBD, it is important to consult a healthcare provider. A sleep study, such as a polysomnogram or polysomnography, can be conducted to diagnose RBD and recommend treatment options. Creating a safe sleeping environment is essential to prevent injuries, and lifestyle changes, such as regular exercise, weight loss, and reducing caffeine and alcohol intake, can also help improve sleep.

Sleep apnea: disrupted sleep due to breathing obstructions
Sleep apnea is a condition that affects your breathing while you sleep. It can severely disrupt your sleep and prevent you from getting the restful sleep you need to function optimally during the day. This condition can also lead to life-threatening complications if left untreated.
There are two main types of sleep apnea: obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA occurs when the muscles in your throat relax during sleep, causing the surrounding tissue to press on your windpipe and block your airway. CSA, on the other hand, is caused by the brain failing to send signals to the breathing-related muscles, preventing them from functioning properly during sleep. In some cases, individuals may experience a combination of both OSA and CSA, known as mixed or complex sleep apnea.
Obstructive sleep apnea is the more common form of the condition, affecting an estimated 1 billion people worldwide between the ages of 30 and 69. While CSA is less prevalent, it is still a relatively common condition. Sleep apnea can affect anyone, regardless of age, but the risk increases as individuals get older.
The breathing obstructions caused by sleep apnea can interrupt your sleep cycle and prevent you from getting restful sleep. When your airway is blocked or your brain fails to regulate your breathing, a survival reflex kicks in, waking you up just enough to resume breathing. This reflex interrupts your sleep and can cause stress on your heart, leading to serious health risks if the condition is not managed effectively.
If you suspect you may have sleep apnea or experience symptoms such as frequent awakenings, insomnia, or restless sleep, it is important to consult a healthcare provider. They can help create a treatment plan to manage your symptoms and prevent potential complications. Treatment options may include weight loss, surgical interventions, or other lifestyle changes recommended by your healthcare provider.

Restless legs syndrome: an urge to move legs, with tingling and crawling sensations
There are several reasons why a person may thrash in their sleep. One of the most common causes is restless legs syndrome (RLS), a movement condition that causes an irresistible urge to move the legs, accompanied by uncomfortable sensations such as tingling, itching, pulling, crawling, throbbing, or creeping. RLS is a sleep disorder triggered by resting and attempting to sleep, and it can severely interrupt sleep, making it difficult to fall asleep or return to sleep after waking up.
People with RLS often experience an irresistible urge to move their legs, which is at least partially relieved by movement. The sensations associated with RLS are typically worse when the individual is inactive and resting, and they usually occur in the late afternoon or evening hours. Leg movement or walking typically provides temporary relief from the discomfort, but the sensations often return as soon as movement ceases.
The symptoms of RLS can vary from person to person and day to day. In moderately severe cases, symptoms might only occur once or twice a week but can still cause significant sleep disruption and functional problems during the day. In severe cases, individuals may experience symptoms more than twice a week. RLS can affect anyone, including children, adolescents, and adults, but it is more common in people over 50, and symptoms tend to worsen with age.
While there is no cure for RLS, treatments are available to help manage the symptoms and improve sleep quality. Doctors may prescribe medications such as anti-seizure drugs or dopaminergic agents. Additionally, the FDA has recently approved a new technology called Tonic Motor Activation (TOMAC), which consists of devices worn on the lower legs that activate the muscles and mimic the sensation of movement, reducing the discomfort caused by RLS. Lifestyle changes, such as regular exercise, weight loss, avoiding caffeine and alcohol in the evening, and reducing stress, can also help improve sleep quality.

Treatment options: melatonin, clonazepam, and lifestyle changes
If you are experiencing sleep disturbances, there are a few treatment options to consider. Melatonin is a popular sleep aid that can be used to treat insomnia and jet lag. Melatonin is a natural hormone that rises two hours before bedtime, promoting a state of quiet wakefulness that helps with sleep. To increase your body's natural melatonin production, you can take 1 to 3 milligrams of melatonin supplements two hours before bedtime. Additionally, you can expose yourself to daylight during the morning and afternoon, while minimizing exposure to blue and green light from electronic devices in the evening.
Clonazepam is another option that is sometimes prescribed off-label to treat insomnia. However, it is generally recommended only after other therapies have been ineffective, as it carries a risk of dependence and misuse. If you decide to take clonazepam, be aware that it should not be taken daily for extended periods, as dependence can develop within two weeks.
Lifestyle changes can also be effective in improving sleep quality. This includes practicing good sleep hygiene, such as maintaining a consistent sleep schedule, creating a comfortable sleeping environment, and limiting exposure to bright lights and electronic devices before bed. Additionally, cognitive-behavioral therapy for insomnia (CBT-I) can help you improve your sleep hygiene and reduce anxiety surrounding sleep.

Frequently asked questions
Thrashing in sleep can be a sign of a sleep disorder or health condition. It could be caused by something like restless leg syndrome, sleep apnea, insomnia, or REM sleep behavior disorder. If you are thrashing in your sleep, it is important to find out why, especially if your movements are compromising the quality of your sleep.
REM sleep behavior disorder (RBD) is a parasomnia, which is a sleep disorder that involves unusual and undesirable physical events or experiences that disrupt your sleep. People with RBD act out their dreams during the REM stage of sleep, and may thrash, kick, punch, or jump out of bed, sometimes harming themselves or their sleeping partners.
Melatonin is the first-line medication for treating RBD, as it rarely causes side effects. Clonazepam is a sedative that has been shown to help people with RBD have fewer or no nightmares, vocalizations, or dream enactment behaviors, but it can cause unpleasant side effects. Pramipexole is primarily prescribed to treat Parkinson's disease and restless leg syndrome, but it can also help treat the symptoms of RBD.
If you think you may have a sleep disorder, you should talk to your doctor. They may recommend a sleep study, which is done overnight in a specialized lab or your own home to characterize your breathing patterns while you sleep. Your doctor may also recommend lifestyle changes such as exercising regularly, losing excess weight, avoiding caffeine and alcohol in the evening, and reducing stress.
