Are you wondering how much REM sleep you really need? Well, buckle up because we’re about to debunk some myths and uncover the truth. The topic of REM sleep has been a subject of much debate and research over the years, with many conflicting opinions on just how much of it we actually need. Some say we need a certain amount of hours, while others argue that it’s all about quality over quantity. But what does the science really say? In this article, we’ll explore the fascinating world of REM sleep and uncover the answers to some of the most common questions about it. So, sit back, relax, and get ready to discover the truth about how much REM sleep we really need.
Understanding REM sleep
What is REM sleep?
REM sleep, short for “Rapid Eye Movement” sleep, is a stage of sleep characterized by the rapid movement of the eyes. This stage of sleep is critical for our bodies and brains to function properly. During REM sleep, our bodies go through a series of changes that help to regulate our circadian rhythms, which are the natural patterns of activity and rest that govern our daily lives.
One of the most important aspects of REM sleep is its role in memory consolidation. During REM sleep, our brains are active and we are more likely to have vivid dreams. It is believed that these dreams help to process and consolidate the memories we have formed during the day. This means that getting enough REM sleep is essential for learning and retaining new information.
In addition to its role in memory consolidation, REM sleep is also important for our physical health. Studies have shown that people who do not get enough REM sleep are at a higher risk for a variety of health problems, including obesity, diabetes, and cardiovascular disease. This is because REM sleep helps to regulate the hormones that control our appetite and metabolism, as well as the stress response that can have negative effects on our health if it is chronically activated.
Overall, REM sleep is a critical aspect of our sleep process that plays a vital role in both our mental and physical health. Understanding the importance of REM sleep can help us to better prioritize getting enough of this critical stage of sleep in our daily lives.

The myths surrounding REM sleep
Myth 1: You need a specific amount of REM sleep per night
- Explanation of the myth
The myth that we need a specific amount of REM sleep per night is a common misconception. Many people believe that there is a set amount of REM sleep that we must obtain in order to be healthy and function properly. This myth has been perpetuated by popular media and various sources, but it is not supported by scientific evidence.
- Debunking the myth
In reality, the amount of REM sleep that we need varies from person to person and can even vary within the same individual from one night to the next. Studies have shown that the amount of REM sleep that we need is not consistent and can range from as little as 5% to over 50% of our total sleep time. Additionally, there is no scientific evidence to support the claim that we need a specific amount of REM sleep per night in order to be healthy.
It is important to note that while the amount of REM sleep that we need may vary, it is still important to get a balanced amount of all stages of sleep in order to maintain optimal health and function. This means that we should aim to get a balanced amount of non-REM and REM sleep, rather than focusing solely on a specific amount of REM sleep.
Myth 2: More REM sleep is better
Myth 3: You can catch up on lost REM sleep
The idea that we can catch up on lost REM sleep by sleeping more at a later time is a commonly held belief. Many people believe that if they have a poor night’s sleep, they can simply make up for it by sleeping more on the weekends or taking a longer nap during the day.
Unfortunately, this belief is not supported by scientific evidence. While it is true that we can catch up on some aspects of sleep, such as physical restoration, REM sleep is not one of them. Research has shown that REM sleep is not accumulative, meaning that it cannot be stored up and used later.
In fact, studies have found that the amount of REM sleep we get each night is closely linked to our overall health and well-being. For example, people who consistently get less REM sleep are more likely to experience problems with memory, mood, and cognitive function. This means that if we miss out on REM sleep one night, we cannot simply make up for it by sleeping more at a later time.
Therefore, it is important to prioritize getting enough REM sleep each night, rather than trying to catch up on lost sleep at a later time.
Factors affecting REM sleep
Sleep disorders are conditions that affect the quality, timing, and amount of sleep a person gets. These disorders can significantly impact the amount of REM sleep a person receives.
- Sleep apnea is a disorder where a person’s breathing is repeatedly interrupted during sleep, causing a decrease in the amount of oxygen in the body. This can lead to a decrease in the amount of REM sleep a person receives.
- Insomnia is a disorder where a person has difficulty falling asleep or staying asleep. This can lead to a decrease in the total amount of sleep a person receives, including REM sleep.
- Narcolepsy is a disorder where a person experiences sudden and uncontrollable attacks of sleep, often resulting in the person falling asleep during the day. This can lead to a decrease in the amount of REM sleep a person receives at night.
It is important to note that sleep disorders can have a significant impact on a person’s overall health and well-being, and it is important to seek medical attention if you suspect you may have a sleep disorder.
The truth about REM sleep
How much REM sleep do we really need?
While the optimal amount of REM sleep varies from person to person, most adults need around 20-25% of their total sleep time to be REM sleep. This translates to about 1.5 to 2 hours of REM sleep per night for the average adult. However, the actual amount of REM sleep an individual needs can be influenced by several factors, including age, gender, and overall health.
For instance, children tend to spend more time in REM sleep than adults, with around 50% of their total sleep time being REM sleep. This is because REM sleep is important for the growth and development of the brain and body during childhood. On the other hand, older adults tend to spend less time in REM sleep, with the percentage of REM sleep decreasing as they age.
Furthermore, gender can also play a role in REM sleep needs. Studies have shown that men tend to spend more time in REM sleep than women, with women experiencing a greater reduction in REM sleep during menopause. Additionally, individuals with certain health conditions, such as sleep disorders or chronic pain, may experience altered REM sleep patterns.
Overall, while the average adult needs around 1.5 to 2 hours of REM sleep per night, the actual amount of REM sleep an individual needs can vary based on a range of factors.
