Sleep is essential for our health and well-being, and it is recommended that adults get around 7-9 hours of sleep per night. Sleep is divided into several stages, including non-rapid eye movement (NREM) sleep and rapid eye movement (REM) sleep, with the latter being known for dreaming and brain activity. While REM sleep is important, all stages of sleep are necessary, and a good night's rest is a balance of all these stages. So, does spending more time in REM sleep mean better sleep?

What You'll Learn
REM sleep is important for dreaming and brain health
Sleep is a complex and dynamic process that affects how we function in ways that scientists are only beginning to understand. While all stages of sleep are important, REM sleep plays a key role in brain health and function.
REM sleep is the stage of sleep where most dreams occur. It is characterised by rapid eye movement, increased heart rate, blood pressure, brain activity, and breathing. The muscles in the arms and legs become temporarily paralysed, preventing sleepers from acting out their dreams.
REM sleep is important for dreaming, and experts believe that dreaming helps individuals process emotions. A study published in the Journal of Neuroscience found that people who spent more time in REM sleep had lower fear-related brain activity when exposed to mild electric shocks the next day. These findings suggest that sufficient REM sleep prior to a traumatic event may reduce the likelihood of developing post-traumatic stress disorder (PTSD).
REM sleep also has other benefits for brain health. During this stage, the brain prunes its synapses, improving memory and problem-solving abilities. It also aids in the development of the central nervous system, which includes the brain and spinal cord. Additionally, REM sleep helps the brain process emotional memories, including those associated with fear, contributing to mood regulation.
To maximise REM sleep, it is important to get enough total sleep. Most REM sleep occurs at the end of the night, and the length of REM episodes increases with each subsequent sleep cycle. Sticking to a consistent sleep schedule and establishing a relaxing bedtime routine can also promote better sleep and increase the likelihood of achieving adequate REM sleep.

REM sleep duration varies with age
Sleep is a fundamental process that allows the body to rest, repair, and restore itself. The quality and quantity of sleep vary from person to person and can even change during an individual's lifetime. While all stages of sleep are essential, the focus here is on REM sleep and how its duration changes with age.
REM sleep, or rapid eye movement sleep, is a stage of sleep characterised by rapid eye movements, increased brain activity, and dreaming. It plays a crucial role in brain health and function, including memory consolidation and emotional processing. The duration of REM sleep varies across different age groups.
Newborns spend approximately half of their sleep time in the REM stage. This proportion gradually decreases over the first six months and continues to decline throughout childhood and adolescence. By the age of 20, most individuals spend just over 20% of their total sleep time in REM sleep.
As people progress into adulthood, the duration of REM sleep remains relatively stable. Most adults need around 1.5 to 2 hours of deep sleep per night, which includes both REM and non-REM stages. However, as individuals advance into older adulthood, there is a slight decrease in REM sleep duration. By the age of 80, the percentage of REM sleep decreases to approximately 17%.
It is worth noting that while the duration of REM sleep changes with age, the overall sleep patterns and needs can also be influenced by various factors such as genetics, health status, and personal circumstances. Additionally, the specific stages of sleep an individual experiences each night can vary based on their body's unique needs. For example, studies have shown that increased REM sleep occurs after learning a new task.
In summary, the duration of REM sleep does indeed vary with age, with newborns spending the most time in this stage and older adults experiencing a slight decrease in REM sleep duration. Understanding these changes and managing sleep effectively can contribute to longer and more restful sleep, promoting overall health and well-being.

REM rebound occurs when you're sleep-deprived
Sleep is a body process that allows the body to rest, repair and restore itself. A good night's sleep is essential for physical health and overall well-being. The amount of sleep one needs varies from person to person and can change during one's lifetime.
Sleep occurs in stages, broadly categorized into rapid eye movement (REM) sleep and non-REM (NREM) sleep. Typically, one enters NREM sleep first and then cycles between its three stages before entering REM sleep. After the first REM cycle, the cycle starts over. A full eight hours of sleep usually includes four or five of these cycles.
REM rebound, also known as REM rebound sleep or the REM rebound effect, is a phenomenon where a person temporarily experiences more REM sleep than usual. During REM rebound, the time spent in REM sleep increases, along with the frequency and intensity of REM sleep stages. While REM sleep is associated with dreams, it is not the only sleep stage in which dreams occur.
REM rebound is the body's natural response to sleep deprivation, stress, and suppression of REM sleep. When an individual is unable to obtain sufficient REM sleep, the pressure to enter this state builds up. As a result, when they finally sleep, they spend a higher percentage of the night in REM sleep.
REM rebound can also be triggered by discontinuing REM-inhibiting drugs, such as benzodiazepines, barbiturates, certain antidepressants, antipsychotics, and cannabis. Alcohol consumption can also lead to REM rebound as it suppresses REM sleep during the first half of the night.

Deep sleep is essential for health and well-being
Sleep is a body process that allows the body to rest, repair and restore itself. It is essential for proper functioning and has links to many health issues. A good night's sleep is a combination of REM sleep and non-REM sleep, with each stage serving a different purpose. While REM sleep is important for brain health and function, deep sleep is essential for health and well-being.
Deep sleep, also known as slow-wave sleep, is the third and fourth stage of the sleep cycle. It is harder to wake someone during this stage, and they would feel disoriented for a few minutes if they were awakened. Deep sleep accounts for about 25% of total sleep time in adults, but babies and children need more deep sleep. As people get older, they need less deep sleep and spend more time in light sleep.
During deep sleep, the body repairs and regenerates tissues, builds bone and muscle, and strengthens the immune system. It is also during this stage that the body regulates the bursts of brain activity that happen in the second stage of sleep. A good night's sleep should include about 25% of deep sleep. If you don't get enough deep sleep, you may feel tired and drained, even if you slept for a long time.
To increase your chances of getting a good night's sleep with the right amount of deep sleep, you can try the following:
- Establish regular sleep-wake habits, including getting up and going to bed at the same time every day.
- Ensure your sleeping space is quiet, comfortable, and restful.
- Leave any devices outside the room while you sleep.
- Establish a bedtime routine that helps you relax before sleep, such as taking a warm shower or listening to music.

Sleep patterns vary from person to person
The sleep cycle consists of two main types of sleep: rapid eye movement (REM) sleep and non-REM (NREM) sleep. There are three NREM stages. When one falls asleep, they typically enter NREM stage 1 and then cycle between NREM stages 2 and 3. After that, they go into REM sleep and start dreaming. After the first REM cycle, a new sleep cycle begins, and the sleeper goes back into stage 1 or 2, and the cycle starts over. One cycle normally takes about 90 to 120 minutes before another begins. Most people go through four or five cycles per night (assuming they get a full eight hours of sleep). Stage 1 NREM sleep is the lightest stage of sleep.
Stage 2 NREM sleep accounts for about 45% of one's time asleep. One will go through multiple rounds of stage 2 NREM sleep, and usually, each one is longer than the last. After stage 2, one moves deeper into stage 3 NREM sleep or enters REM sleep. The deepest stage of NREM sleep is stage 3, which makes up about 25% of one's total sleep time in adults. However, babies and children need more stage 3 sleep, and the older one gets, the less they need. In stage 3, one's brain waves are slow but strong, and the body takes advantage of this very deep sleep stage to repair injuries and reinforce the immune system. The same bursts of brain activity that happen in stage 2 can also happen in stage 3, and brain waves specific to stage 3 help regulate those bursts. One needs stage 3 NREM sleep to wake up feeling rested. Without enough stage 3 sleep, one may feel tired and drained even if they slept for a long time.
REM sleep is important for brain health and function. It is during this stage that the brain repairs itself and processes emotional experiences. It also transfers short-term memories into long-term memories. If one does not get enough REM sleep, they may experience symptoms such as difficulty concentrating, mood changes, and impaired motor skills. To increase REM sleep, one needs to get more sleep overall.
While all stages of sleep are necessary, and none is better than any other, a balance of around 25% REM and 25% of the deepest NREM sleep is needed to maintain health and well-being. Getting the right balance of sleep in each stage is essential to health.

Frequently asked questions
REM stands for rapid eye movement sleep. It is one of the two types of sleep, the other being non-REM (NREM) sleep. During REM sleep, your eyes move rapidly behind closed eyes, your heart rate speeds up, your breathing becomes irregular, and your brain is highly active. Dreaming occurs during REM sleep.
There is no minimum requirement for REM sleep. However, experts believe that REM sleep is important for brain health and function, as well as for dreaming. Most adults need around 20% of their total sleep time to be REM sleep, which equates to about 1.5-2 hours per night.
To increase your REM sleep, you need to get more sleep overall. You can improve your sleep by creating a relaxing bedtime routine, setting a sleep schedule and sticking to it, and avoiding nicotine and caffeine.
