A Bit More Detail
What does this really mean in simple terms
REM (Rapid Eye Movement) sleep is a stage of sleep characterized by rapid eye movements, increased brain activity, and vivid dreaming. It is one of the most important stages of sleep and plays a crucial role in our physical and mental well-being. REM sleep is so named because of the rapid eye movements that occur during this stage, which are thought to be associated with the visual experiences that occur in our dreams (there may be some evidence the eyes move to maintain lubrication to prevent damage, we’ll discuss this later)
The function of REM sleep in the human body and mind is complex and multifaceted. It has been shown to play a role in the consolidation of memories, the regulation of our emotions, and the restoration and repair of our bodies. Here, we will explore the various functions of REM sleep in greater detail.
Memory Consolidation:
REM sleep is believed to play a crucial role in memory consolidation, which is the process by which our brains take the information that we have learned during the day and store it for long-term use. During REM sleep, the brain is highly active, and it is thought that this increased activity is necessary for our brains to process and consolidate new information. In fact, studies have shown that people who are deprived of REM sleep are more likely to forget the information that they have learned.
Regulation of Emotions:
REM sleep is also believed to play a role in the regulation of our emotions. During this stage of sleep, the brain is highly active, and it is thought that this increased activity helps to regulate our emotions and process any emotional experiences that we have had during the day. In fact, studies have shown that people who suffer from anxiety and depression often experience disruptions in their REM sleep, which can lead to an increase in symptoms.
Restoration and Repair of the Body:
REM sleep is also essential for the restoration and repair of our bodies. During this stage of sleep, our bodies undergo a series of physiological changes that help to repair and restore our muscles, tissues, and cells. For example, during REM sleep, the production of growth hormone increases, which helps to repair and restore our tissues and muscles. Additionally, REM sleep has been shown to have a positive impact on our immune system, helping us to fight off infections and illnesses.
Vivid Dreaming:
Perhaps one of the most well-known functions of REM sleep is its role in vivid dreaming. During REM sleep, our brains are highly active, and it is thought that this increased activity is responsible for the vivid and intense dreams that we experience. These dreams can range from peaceful and pleasant to vivid and disturbing, but they all serve to help us process our experiences and emotions from the day.
REM sleep is an essential stage of sleep that plays a crucial role in our physical and mental well-being. It helps to consolidate our memories, regulate our emotions, and restore and repair our bodies. Additionally, it is responsible for the vivid and intense dreams that we experience. By understanding the importance of REM sleep, we can better appreciate the role of sleep in our lives and work to maintain healthy sleep habits that support our overall health and mental performance.

The two stages of REM sleep, Tonic and Phasic:
Tonic and phasic REM sleep are two distinct stages of the REM sleep cycle. Understanding the difference between these two stages is essential for appreciating the role of REM sleep in our lives and how it contributes to our overall health and well-being. In a lot of literature you will only see stages mentioned in the N-REM sleep or deeper stages of sleep and this is not the case.
Tonic REM Sleep:
Tonic REM sleep is characterized by a general state of muscular atonia or muscle paralysis. During this stage, the muscles are relaxed and inactive, and it is difficult for an individual to move or act out their dreams. This stage of sleep is considered to be the deepest stage of REM sleep, and it is during this stage that the body undergoes the most restorative processes.
The main function of tonic REM sleep is to promote physical restoration and repair. During this stage, the body releases growth hormone, which helps repair and restore tissues, muscles, and cells. Additionally, tonic REM sleep is thought to play a role in regulating our blood pressure and heart rate, which helps maintain our physical health. During this stage we are at our most vulnerable to dangers from the outside world, whatever they may be, if there was ever a stage that could pop us out the gene pool this is it. Good job we have Phasic REM to save the day.
Phasic REM Sleep:
Phasic REM sleep is characterized by rapid eye movements and increased brain activity. This stage of REM sleep is associated with vivid and intense dreaming, as the brain is highly active and processing our experiences and emotions from the day.
The main function of phasic REM sleep is to support our mental health and well-being. During this stage, the brain processes and consolidates memories, helping us retain information that we have learned during the day. Additionally, phasic REM sleep helps regulate our emotions, reducing symptoms of anxiety and depression.
One of the key differences between tonic and phasic REM sleep is the level of muscle activity. During tonic REM sleep, the muscles are relaxed and inactive (complete muscle atonia of the voluntary muscle groups), while during phasic REM sleep, the muscles are more active and may even experience twitching or movement.
A note about muscle activity or lack of it during REM. There are two areas of the voluntary muscle’s that seem to escape the muscle atonia, ocular muscles and the middle ear muscles. Later we’ll discuss why we think this happens.
Another difference between these two stages is the level of brain activity. During tonic REM sleep, the brain is relatively inactive, while during phasic REM sleep, the brain is highly active and processing information. This increased brain activity is responsible for the vivid and intense dreaming that we experience during phasic REM sleep.
It is important to note that tonic and phasic REM sleep occur together, and individuals will cycle between these two stages multiple times throughout the night. The duration and intensity of each stage may vary from person to person, and from night to night.
Tonic and phasic REM sleep are two distinct stages of the REM sleep cycle that play important roles in our physical and mental well-being. Tonic REM sleep is characterized by muscle paralysis and promotes physical restoration and repair, while phasic REM sleep is associated with vivid dreaming and supports our mental health and well-being. By understanding the differences between these two stages of REM sleep, we can better appreciate the role of sleep in our lives and work to maintain healthy sleep habits that support our overall health and well-being.
The paralizing world of REM sleep and how we survive
During REM (Rapid Eye Movement) sleep, the body undergoes a unique state of paralysis known as REM atonia. This paralysis is necessary to prevent the body from acting out dreams and potentially causing injury to oneself or others. However, there are certain voluntary muscles that are not affected by this paralysis and continue to function during REM sleep.
These voluntary muscles include the respiratory muscles, the ocular muscles responsible for eye movement, and the middle ear muscles. These muscles are essential for basic bodily functions and require continued activity during sleep to maintain proper functioning.
The respiratory muscles are responsible for controlling breathing during sleep, and any failure of these muscles could lead to dangerous health consequences. As a result, they remain active during REM sleep to ensure that proper breathing continues throughout the night.
The ocular muscles are responsible for controlling eye movement during sleep and are important for processing visual information and maintaining proper orientation. They continue to function during REM sleep to allow for the eyes to move rapidly back and forth, a hallmark of this stage of sleep.
The middle ear muscles are responsible for dampening the sounds that reach the inner ear, which is important for maintaining sleep quality. They remain active during REM sleep to ensure that loud sounds do not disrupt the sleep cycle.
While the majority of the body’s voluntary muscles are paralyzed during REM sleep, the few muscles that remain active play a crucial role in maintaining basic bodily functions and sleep quality. It is important to understand the mechanics of REM atonia and the muscles that are not affected by it to better understand the complexities of sleep and its effects on the body.
Martch of the hormones
REM sleep is a unique stage of sleep that plays a vital role in our overall health and well-being. During REM sleep, our bodies release a number of hormones that play important roles in regulating our physical and mental health. In this article, we will explore the hormones released during REM sleep and what they do to the mind and body.
Melatonin:
Melatonin is a hormone that is produced by the pineal gland and is involved in regulating our sleep-wake cycle. During REM sleep, levels of melatonin increase, promoting feelings of drowsiness and helping us fall asleep more easily. Melatonin also helps regulate our circadian rhythm, ensuring that we are alert and awake during the day and sleepy at night.
Serotonin:
Serotonin is a hormone that is produced by the brain and is involved in regulating our mood, appetite, and sleep. During REM sleep, levels of serotonin increase, promoting feelings of well-being and helping regulate our emotions. Serotonin also helps regulate our sleep-wake cycle, ensuring that we are able to fall asleep and stay asleep throughout the night.
Growth Hormone:
Growth hormone is a hormone produced by the pituitary gland that plays an important role in growth and development. During REM sleep, levels of growth hormone increase, promoting tissue repair and restoration, and supporting muscle growth. This hormone is especially important for children and adolescents, as it helps promote healthy growth and development.
Cortisol:
Cortisol is a hormone produced by the adrenal gland and is involved in regulating our stress levels. During REM sleep, cortisol levels decrease, reducing feelings of stress and anxiety. Cortisol also helps regulate our sleep-wake cycle, ensuring that we are able to fall asleep and stay asleep throughout the night.
REM sleep is a stage of sleep that plays a vital role in regulating our physical and mental health. During REM sleep, our bodies release a number of hormones that promote feelings of well-being, reduce stress and anxiety, and promote tissue repair and restoration. By understanding the role of hormones in REM sleep, we can better appreciate the importance of sleep in our lives and work to maintain healthy sleep habits that support our overall health and well-being
Manageable Sleep Goals
Making a positive change a little bit at a time
- Stick to a consistent sleep schedule:
Try to go to bed and wake up at the same time every day, even on weekends. This helps regulate your body’s natural sleep-wake cycle, which can improve the quality of your REM sleep. - Create a relaxing bedtime routine:
Establish a routine that helps you wind down before bed. This might include taking a warm bath, reading a book, or doing some light stretching. - Avoid caffeine and alcohol:
Both caffeine and alcohol can interfere with REM sleep, so try to avoid consuming these substances in the evening. - Exercise regularly:
Regular exercise has been shown to improve the quality of REM sleep. Aim for at least 30 minutes of moderate-intensity exercise most days of the week. - Manage stress:
Stress can interfere with sleep, so try to find ways to manage your stress levels. This might include practicing relaxation techniques like deep breathing or meditation. - Keep your bedroom dark and cool:
Create a sleep-conducive environment by keeping your bedroom dark, quiet, and cool. This can help promote deeper, more restful REM sleep. - Limit screen time before bed:
The blue light emitted by electronic devices can suppress the production of melatonin, a hormone that helps regulate sleep. Try to limit your exposure to screens for at least an hour before bed. - Consider a sleep tracker:
If you’re having trouble determining how much REM sleep you’re getting, consider using a sleep tracker. This can help you identify patterns and make adjustments to your sleep habits accordingly.
