What is REM Sleep?

REM (Rapid Eye Movement) also known as REM paradoxical sleep is a stage of sleep characterised by rapid eye movements, vivid dreams, and increased brain activity resembling wakefulness.

It is one of the four stages of sleep and typically occurs cyclically throughout the night, with each REM period becoming progressively longer. During REM sleep, the body experiences muscle paralysis, except for the muscles essential for breathing and eye movement.

This stage is crucial for cognitive function, memory consolidation, emotional processing, and overall brain health. REM sleep is believed to play a role in learning, creativity, and maintaining emotional well-being.

When you are sleeping well you are getting good rem sleep, meaning you benefit from all of the above.

How much REM sleep do you need?

The amount of REM sleep needed varies depending on factors such as age and individual differences. Generally, adults spend about 20-25% of their total sleep time in REM sleep, with each REM cycle lasting around 90-120 minutes and occurring multiple times throughout the night.

While there isn’t a specific recommended duration of REM sleep, it’s considered essential for cognitive function, memory consolidation, and emotional processing. Insufficient REM sleep can lead to cognitive impairment, mood disturbances, and difficulty concentrating.

However, it’s worth noting that REM sleep requirements may differ from person to person, and focusing solely on achieving a certain amount of REM sleep may not be as important as ensuring overall sleep quality and duration.

REM sleep behaviour disorder (RBD) or REM sleep disorder is a sleep disorder where individuals act out their dreams physically, often vividly and violently, due to a lack of muscle paralysis during REM sleep.

How to improve REM sleep?

It can be very positive to get more REM sleep. Improving REM sleep can enhance overall sleep quality and promote cognitive function, emotional well-being, and memory consolidation. Here are some tips to help improve REM sleep:


Prioritise sleep hygiene

Establish a consistent sleep schedule, create a relaxing bedtime routine, and ensure your sleep environment is conducive to rest, with minimal noise, light, and distractions.


Get regular exercise

Engage in regular physical activity, but avoid vigorous exercise close to bedtime, as it may interfere with sleep. Exercise during the day can promote deeper and more restful sleep, including REM sleep.


Manage stress

Practice stress-reduction techniques such as mindfulness, deep breathing exercises, yoga, or meditation to alleviate anxiety and promote relaxation before bedtime.

Limit stimulants

Avoid consuming caffeine, nicotine, and alcohol close to bedtime, as they can disrupt sleep patterns and suppress REM sleep.


Maintain a healthy diet

Eat a balanced diet rich in fruits and vegetables. Avoid heavy or spicy meals close to bedtime, as they may cause discomfort and disrupt sleep. Processed or starchy carbohydrates and refined sugar can also interfere with sleep.


Create a sleep-conductive environment

Keep your bedroom cool, dark, and quiet, and invest in a comfortable mattress and pillows to promote deeper and more restful sleep.

Seek treatment for sleep disorder

If you suspect you have a sleep disorder such as sleep apnea or insomnia, it’s important that you seek help. These conditions can significantly disrupt REM sleep and overall sleep quality.

By incorporating these strategies into your daily routine, you can improve REM sleep and enjoy more restful and rejuvenating nights of sleep.

REM Sleep vs Deep Sleep

What is the REM phase of sleep?

It is a stage of sleep characterized by rapid eye movements, vivid dreams, and muscle paralysis, essential for memory consolidation and emotional regulation.

The main difference between deep sleep (also known as slow-wave sleep or N3) and REM sleep lies in their distinct characteristics and functions. Deep sleep is characterised by slow brainwave patterns, minimal eye movement, and decreased physiological activity. It is considered the most restorative stage of sleep, essential for physical recovery, tissue repair, and growth hormone release.

In contrast, REM sleep is marked by rapid eye movements, vivid dreams, and increased brain activity resembling wakefulness. It plays a crucial role in cognitive function, memory consolidation, emotional processing, and dream formation. While both stages are important for overall sleep quality and health, they serve different functions and occur at different points throughout the sleep cycle.
