Ever wonder why we sleep? Regardless of your age, sleep is an important part of life. REM sleep, especially, is important to overall body and brain functions. So, how much REM sleep do you need?

Good Sleep Equals a Healthy Body

Good sleep means improved brain performance, mood, and overall health. Imagine not getting adequate sleep for even two days. You will feel tired and worn out. You might have some persistent headaches and constant fatigue. This is a clear indication that your body needs some rest through sleep.

It is during sleep that our nerve cells communicate with each other. Recent studies even suggest that neural pathways and bridges are restored and strengthened during our sleep time. In turn, lack of good sleep regularly puts you at risk for many health risks, including heart disease, obesity, and dementia.

And this is precisely where the importance of REM sleep comes in.

REM Sleep

Rapid eye movement (REM) sleep is a stage the brain undergoes during the sleep cycle. This stage of sleep is mainly associated with dreaming and memory consolidation. A series of physiological changes in the body mark REM sleep. This includes eye movement that can be rapid, especially when you are dreaming, muscle relaxation, and increased brain activity.

Signs of REM Sleep

During REM sleep, your body and brain undergo several changes. Some notable signs of REM sleep include:

  • Body temperature changes
  • Rapid eye movement
  • Sexual arousal
  • Increased heart rate
  • Increased blood pressure

Why REM Sleep Is Important

Sleep is important for everyone. Having enough sleep every day improves your well-being and makes you feel fresh. Of all sleep, REM sleep plays an essential role in dreaming, memory, emotional processing, and healthy brain development. Here is some of the importance of REM sleep:


If you did not know, most of our dreams occur during the REM sleep stage. Remember, there are different stages of sleep. Even though dreaming can take place in and at various stages of sleeping, it is during REM sleep that people. tend to have the most vivid dreams.

Emotional Processing

REM sleep also plays an important role in emotional processing. After that wonderful or not-so-good day you have experienced, having a good sleep will help your brain process emotions during REM sleep. In other words, REM sleep is the time when your brain may decompress by processing and compartmentalizing thoughts and events from the day. Thus, having a night of inadequate sleep can lead to decreased emotional memory consolidation.

Brain Development

Studies have suggested REM sleep plays an important role in brain development since infants spend most of their sleep time in REM. This is attributed to the brain’s high activity levels, which help to develop and strengthen neural connections.

Sleep Disorders That Affect REM Sleep

Several sleep disorders can affect your REM sleep. Sleep disorders can make it difficult for you to have good sleep. Seeking medical assistance from a therapist can help improve your sleep quality. These sleep disorders include:

  • Sleep apnea
  • Insomnia
  • REM sleep behavior disorder (RBD)
  • Narcolepsy

How much REM sleep do you need?

While it is not yet established how much REM sleep you need, this stage of sleep is important for dreaming and helps you process emotions. Infants need the most REM sleep when their brains are still developing. Newborns usually spend 8 hours of REM sleep each day, while adults have about 2 hours of REM sleep each night. As time progresses, your body alters your sleep duration and even sleep pattern depending on your lifestyle. Therefore, your REM sleep can vary based on your body’s needs.

How To Get More REM Sleep

Inadequate sleep can put you at risk of diseases and disorders affecting your well-being. Undiagnosed sleep disorders and insomnia can lead to a lack of REM sleep, seriously impacting your life and overall health. Good sleep is crucial for our bodies and minds. Without it, we can face difficulties concentrating in classrooms, workplaces, or other places. Here are a few ways to get more REM sleep:

Get regular exercise.

Doing exercise for about 30 minutes daily can help you get more REM sleep. Exercising helps to raise your body temperature, and when the body temperature starts to fall, the decline helps to facilitate sleepiness.

Develop a sleep schedule.

You might have different sleep and wake times depending on your schedules. This can interfere with REM sleep. To get more REM sleep, you must have a sleep schedule. Ensure you go to bed and wake up at the same time every day.

Do not take alcohol, caffeine, or cigarettes.

These are stimulants that can interfere with your sleep. Taking alcohol before bed can delay when you first enter REM sleep.

Treat sleep disorders.

Sleep disorders such as insomnia or sleep apnea can affect your REM sleep. If a sleep disorder causes REM sleep disruptions, it would be wise to treat the disorder, which can lead to a gradual return to normal proportions of REM sleep.
