Quick Answer
REM (Rapid Eye Movement) sleep is the stage of sleep most closely linked to dreaming, memory, learning, emotional processing, and brain health. To improve REM sleep naturally, maintain a consistent sleep schedule, manage stress, limit alcohol before bed, reduce evening screen time, exercise regularly, and create a sleep-friendly environment. These healthy habits may help your body spend more time in restorative REM sleep over time.
Introduction
Several years ago, I went through a period where I was technically getting enough sleep but still felt mentally exhausted every morning.
I wasn’t just physically tired. I struggled to concentrate during project meetings, forgot small details, and found it harder to make decisions throughout the day. At first, I blamed work pressure. After all, construction projects rarely slow down.
Looking back, I realized the problem wasn’t simply the number of hours I slept—it was the quality of my sleep.
That experience taught me an important lesson: restorative sleep is made up of different stages, and each one has a unique purpose. One of the most important is REM sleep, the stage that helps your brain recover, process emotions, and strengthen memories.
If you’ve been wondering how to improve REM sleep or how to increase REM sleep naturally, the good news is that many daily habits can influence it. Small, consistent changes often make a bigger difference than searching for a quick fix.
What Is REM Sleep and Why Does It Matter?
Sleep isn’t one continuous state. Instead, your brain moves through several stages multiple times each night.
A typical sleep cycle includes:
- Light sleep
- Deep sleep
- REM (Rapid Eye Movement) sleep
REM sleep usually becomes longer as the night progresses, with the longest REM periods often occurring during the final few hours before waking.
During this stage:
- Your brain becomes highly active.
- Most vivid dreaming occurs.
- Memories are organized and strengthened.
- Emotional experiences are processed.
- Learning and creativity are supported.
While deep sleep is often associated with physical recovery, REM sleep plays a particularly important role in mental recovery.
Researchers continue to study exactly how REM sleep affects long-term brain health, but evidence suggests it contributes to learning, emotional regulation, and cognitive performance.
That’s one reason why people who regularly cut their sleep short often notice problems with concentration, mood, and memory.
How Much REM Sleep Do You Really Need?
One of the most common questions people ask is whether there’s an ideal amount of REM sleep.
Unlike total sleep time, there isn’t a specific number of hours everyone should aim for.
Instead, REM sleep typically represents about 20–25% of total sleep in healthy adults.
For someone sleeping eight hours, that generally equals around 90 to 120 minutes of REM sleep.
However, these numbers naturally vary depending on:
- Age
- Overall health
- Sleep duration
- Lifestyle habits
- Certain medications
It’s also important to remember that consumer sleep trackers provide estimates rather than exact measurements.
Instead of focusing on achieving a perfect REM score every night, it’s more useful to look for long-term trends and pay attention to how rested you feel during the day. Understanding your sleep patterns is often the first step if you’re trying to increase REM sleep naturally.
What Causes Low REM Sleep?
Several factors may reduce the amount of REM sleep your body gets during the night.
Understanding these causes is often the first step toward improving sleep quality.
Inconsistent Sleep Schedule
Your brain follows an internal clock known as the circadian rhythm.
Going to bed at different times every night can disrupt this rhythm, making it more difficult for your body to move smoothly through normal sleep cycles.
Consistency matters more than perfection.
Even keeping your bedtime within the same 30- to 60-minute window each day may help support healthier sleep patterns.
Chronic Stress
Stress is one of the biggest obstacles to healthy sleep.
When you’re under constant pressure, your body produces higher levels of cortisol—the primary stress hormone.
While cortisol is essential during the day, elevated levels at night may interfere with your ability to move naturally into restorative sleep stages.
This is something I experienced myself during demanding construction projects. Even when I felt physically exhausted, my mind continued planning tomorrow’s meetings, reviewing schedules, and thinking about unresolved issues.
Eventually, I realized that relaxing before bed wasn’t a luxury—it was part of preparing my brain for quality sleep.
Alcohol Before Bed
Many people believe alcohol helps them sleep because it can make them feel drowsy.
However, alcohol may actually reduce sleep quality by disrupting the normal structure of sleep later in the night.
Some people experience more fragmented sleep, shorter REM periods, and increased awakenings after drinking alcohol close to bedtime.
Sleep Disorders
Certain medical conditions may interfere with healthy REM sleep.
Examples include:
- Obstructive sleep apnea
- Chronic insomnia
- Restless legs syndrome
- Periodic limb movement disorder
Sleep apnea deserves particular attention because repeated breathing interruptions may prevent the brain from completing normal sleep cycles.
People often assume they’re sleeping for eight hours, when in reality their sleep is being interrupted dozens of times without them remembering it.
Certain Medications
Some medications may influence REM sleep.
Examples include certain:
- Antidepressants
- Stimulants
- Beta blockers
- Sleep medications
If you suspect a medication is affecting your sleep, don’t stop taking it on your own. Instead, discuss your concerns with your healthcare provider.
How Can You Improve or Increase REM Sleep Naturally?
Fortunately, many of the habits that improve overall sleep quality also support healthier REM sleep.
Rather than focusing on one “magic” solution, aim to create an environment that allows your body to move naturally through every stage of sleep.
If you’re looking for how to increase REM sleep, the following evidence-based habits may help your body spend more time in this important stage of the sleep cycle over the long term
Maintain a Consistent Sleep Schedule
Your circadian rhythm thrives on regularity.
Going to bed and waking up at approximately the same time each day helps your brain anticipate when it’s time to sleep.
This consistency may improve the efficiency of your sleep cycles, including REM sleep.
Try to maintain similar sleep and wake times—even on weekends.
Sleeping in for several extra hours every Saturday and Sunday can create a type of “social jet lag” that makes Monday mornings more difficult.
Limit Alcohol Before Bed
If you choose to drink alcohol, try avoiding it within several hours of bedtime whenever possible.
Although alcohol may help some people fall asleep faster, research suggests it can reduce sleep quality during the second half of the night, when REM sleep naturally becomes longer.
Reducing evening alcohol intake may help preserve healthier sleep architecture and improve how refreshed you feel the next morning.
Manage Stress Before Sleeping
One of the most effective ways to support REM sleep is by calming your mind before bed.
This doesn’t require elaborate routines.
Simple practices may include:
- Reading a book
- Gentle stretching
- Slow breathing exercises
- Journaling tomorrow’s tasks
- Listening to calming music
- Practicing mindfulness
The goal isn’t to force sleep.
The goal is to reduce mental stimulation so your brain can transition naturally into healthy sleep cycles.
Over time, these small habits often become easier and more effective.
Get Morning Sunlight
One of the simplest ways to support healthy REM sleep starts shortly after you wake up.
Morning sunlight helps regulate your circadian rhythm—the internal clock that tells your body when to feel alert and when to prepare for sleep.
Even 15 to 30 minutes of natural daylight, especially within the first hour after waking, may help reinforce this daily rhythm. A well-regulated body clock can make it easier to fall asleep at night and move through your natural sleep cycles more efficiently.
If getting outside isn’t always possible, sitting near a bright window is still better than remaining in artificial indoor lighting all morning.
Exercise Regularly
Regular physical activity is associated with better overall sleep quality.
Exercise may help you:
- Fall asleep more easily
- Sleep more soundly
- Reduce stress
- Improve mood
- Support healthier sleep cycles
Moderate activities such as brisk walking, cycling, swimming, or strength training are excellent choices for most adults.
Timing also matters.
Some people find vigorous exercise immediately before bed leaves them feeling too alert, while exercising earlier in the day helps them sleep more comfortably at night.
The key is consistency rather than intensity.
Reduce Evening Screen Time
Phones, tablets, computers, and televisions expose your eyes to blue light while also keeping your brain mentally engaged.
Late-night scrolling, gaming, or checking emails may delay your body’s natural production of melatonin—the hormone that signals it’s time to sleep.
Instead of using screens during the last hour before bed, consider replacing them with relaxing activities such as:
- Reading a printed book
- Gentle stretching
- Meditation
- Listening to calming music
- Journaling
Reducing stimulation before bedtime gives your brain a better opportunity to transition into restorative sleep.
Create a Cool, Dark Sleep Environment
Your bedroom should support sleep rather than compete with it.
Simple adjustments can make a noticeable difference, including:
- Keeping the room cool
- Using blackout curtains
- Minimizing outside noise
- Choosing a comfortable mattress and pillow
- Removing unnecessary light sources
Many people underestimate how much environmental factors influence sleep quality.
Small improvements often lead to better sleep over time.
Avoid Late Caffeine
Caffeine doesn’t affect everyone equally, but it can remain in your body for several hours.
For some people, even an afternoon coffee may still influence sleep later that night.
If you’re trying to improve REM sleep, consider limiting caffeine during the late afternoon and evening.
Replacing coffee with herbal tea or water later in the day may help support healthier sleep patterns.
Eat for Better Sleep
There’s no single “REM sleep diet,” but your overall eating habits can influence sleep quality.
A balanced diet that includes:
- Lean protein
- Fruits
- Vegetables
- Whole grains
- Healthy fats
supports overall health, including sleep.
Large meals immediately before bedtime may increase discomfort or indigestion, making restful sleep more difficult.
Instead, try finishing dinner a few hours before going to bed whenever possible.
Treat Underlying Sleep Disorders
Sometimes healthy habits alone aren’t enough.
Conditions such as:
- Sleep apnea
- Chronic insomnia
- Restless legs syndrome
may significantly reduce sleep quality, including REM sleep.
If you regularly wake feeling exhausted despite sleeping seven to nine hours, snore loudly, experience breathing pauses during sleep, or struggle with persistent insomnia, it’s important to discuss these symptoms with a healthcare professional.
Treating an underlying sleep disorder often leads to substantial improvements in overall sleep quality.
What Happens If You Don’t Get Enough REM Sleep?
Occasionally getting less REM sleep than usual isn’t typically a cause for concern.
However, consistently poor REM sleep may affect how you feel and function during the day.
Research suggests inadequate REM sleep may contribute to:
- Difficulty concentrating
- Poor memory
- Reduced learning ability
- Mood changes
- Increased irritability
- Reduced creativity
- Daytime fatigue
Because REM sleep is closely linked with brain function, protecting this stage of sleep is an important part of long-term health.
REM Sleep vs. Deep Sleep: What’s the Difference?
Many people assume REM sleep and deep sleep serve the same purpose.
In reality, they complement one another.
Deep sleep is primarily associated with physical recovery.
During deep sleep, your body repairs tissues, supports immune function, releases growth hormone, and restores physical energy.
REM sleep, on the other hand, is often called the brain’s recovery stage.
It plays a major role in:
- Memory consolidation
- Learning
- Emotional processing
- Creativity
- Cognitive performance
Both stages are essential.
Rather than trying to maximize one at the expense of the other, focus on building habits that support healthy sleep overall.
Can Sleep Trackers Measure REM Sleep Accurately?
Modern smartwatches and sleep trackers have made people much more aware of their sleep habits.
These devices estimate sleep stages using information such as:
- Heart rate
- Movement
- Heart rate variability
- Breathing patterns
While they provide useful insights, they cannot directly measure brain activity like a clinical sleep study.
That means REM sleep estimates should be viewed as helpful approximations rather than precise medical measurements.
Instead of worrying about nightly fluctuations, use sleep trackers to identify long-term trends and determine whether lifestyle changes appear to improve your sleep over time.
