Why can’t I move when I wake up? Sleep paralysis explained

Write an article about

Sleep paralysis can be scary, especially if it happens for the first time. You may wake up and realize you cannot move or speak, even though you are aware of what is happening around you.

Sleep paralysis happens when your body and brain are briefly out of sync. During rapid eye movement (REM) sleep, your brain relaxes your muscles so you do not act out your dreams. With sleep paralysis, that muscle relaxation lasts a little longer than it should, even after you wake up. As a result, you are conscious but unable to move for a short time. Episodes usually last only seconds or a few minutes and often end on their own.

Some people also experience vivid dreams or hallucinations during sleep paralysis. This can include seeing people or hearing things that are not there or feeling pressure on the chest. While these symptoms can feel intense, isolated sleep paralysis is not dangerous and does not mean something is seriously wrong.

Common triggers and risk factors

Sleep paralysis can affect people of all ages, but certain habits and conditions can make it more likely. Common triggers and risk factors include:

Not getting enough sleep
Going to bed and waking up at different times each day
Increased stress or anxiety
Sleeping on your back
Working night shifts or erratic work schedules
Drinking alcohol close to bedtime
Certain medications used to treat anxiety
Other sleep disorders, such as narcolepsy

Sleep deprivation and irregular sleep schedules are among the most common triggers. When you lack sufficient sleep, your body may enter REM sleep more quickly or more deeply, which can increase the chance of sleep paralysis.

Does sleep position matter?

Yes, sleep position can make a difference for some people.

Sleep paralysis happens more often when sleeping on the back. This position, also called supine sleeping, is linked to a higher risk of episodes. While experts are still studying why this happens, sleeping on the side may help reduce how often sleep paralysis occurs.

If you tend to roll onto your back at night, placing a pillow behind you or using body pillows can help you stay on your side.

How is sleep paralysis managed?

For most people, managing sleep paralysis starts with improving sleep habits and reducing known triggers. Helpful strategies include:

Keep a regular sleep schedule. Try to go to bed and wake up at the same time every day, even on weekends.
Get enough sleep. Adults should aim for at least seven hours of sleep each night.
Avoid alcohol, especially close to bedtime. Alcohol can disrupt REM sleep and may increase the chance of sleep paralysis episodes.
Reduce stress. Relaxation techniques such as deep breathing or gentle stretching before bed may help.
Change sleep position. Side sleeping instead of back sleeping may lower episode frequency.
Address other sleep or health conditions. Treating insomnia, anxiety, or sleep apnea can help reduce episodes and ensure better sleep quality.

If sleep paralysis happens often or causes significant distress, a doctor may recommend additional treatment options. In some cases, cognitive behavioral therapy can help improve sleep quality and reduce sleep disruptions that may trigger sleep paralysis. There are no recommended medications for isolated sleep paralysis.

Key takeaway: Maintaining regular and consistent sleep schedules and avoiding common triggers are the most effective first steps for managing sleep paralysis.

When to talk with a doctor

You should talk with a doctor if sleep paralysis happens frequently, feels overwhelming, or occurs along with excessive daytime sleepiness. A health care professional can help determine whether another sleep disorder or medical condition may be involved and guide you on next steps.
