How much rem sleep do you need per night
Until the s, most people thought of sleep as a passive, dormant part of our daily lives. Fast forward 70 years and we now know that our brains are very active during sleep. Moreover, sleep affects our daily functioning and our physical and mental health in many ways that we are just beginning to understand. Nerve-signaling chemicals called neurotransmitters control whether we are asleep or awake by acting on different groups of nerve cells, or neurons, in the brain. Neurons in the brainstem, which connects the brain with the spinal cord, produce neurotransmitters such as serotonin and norepinephrine that keep some parts of the brain active while we are awake.SEE VIDEO BY TOPIC: Sleep - What is Sleep - Benefits Of Deep Sleep - How Sleep Works - Sleep Cycles

Slow wave sleep, also called deep sleep, is an important stage in the sleep cycle that enables proper brain function and memory. While most adults are aware that they should aim for between 7 and 9 hours of sleep each night, the science of sleep is quite complex.
The two main categories of sleep are called rapid eye movement REM sleep and non-REM sleep, and each has important stages. There may be some ways to get both better sleep and more deep sleep each night, allowing a person to wake up feeling more rested and refreshed. The first stage of the sleep cycle is a transition period during which the body and brain shift from a state of wakefulness to one of sleep.
This period is relatively short, lasting only a few minutes, and the sleep is fairly light. People may wake up from this stage of sleep more easily than from other stages. During stage one, the body starts to slow its rhythms down.
The heart rate and breathing rate slow down, and the eyes begin to relax. The muscles also relax but may occasionally twitch. The brain unwinds along with the body. The brain waves start slowing down as brain activity and sensory stimulation decrease.
The second stage of non-REM sleep is another lighter stage of sleep that occurs as the body starts transitioning to deeper sleep. As the National Institute of Neurological Disorders and Stroke note, humans spend most of their time during the sleep cycle in this stage of sleep.
In the body, the heart rate and breathing rate slow down even more. The muscles relax further, and eye movements stop. The body temperature also goes down. Although the brain waves slow down further, this stage also includes small bursts of electrical signals in the brain.
Deep sleep or slow wave sleep is the third stage of non-REM sleep. Although the body completes a few cycles throughout the night, the third stage occurs in longer periods during the first part of the night. In the body, the heart rate and breathing rate are at their lowest during this part of the sleep cycle. The muscles and eyes are also very relaxed, and the brain waves become even slower. It may be very difficult to wake someone from this stage of sleep, which is when sleep disorders, such as sleepwalking, occur.
REM sleep is the fourth and final stage of the sleep cycle. The body first goes into REM sleep about 90 minutes after falling asleep. During this stage of sleep, the eyes dart back and forth behind the closed eyelids.
This state is closer to the wakeful state than the other stages of sleep. In REM sleep, the brain waves start to resemble the brain waves of the wakeful state. The heartbeat and breathing rate speed up. The REM stage is also when most dreaming occurs. The brain temporarily paralyzes the arms and legs to prevent the body from acting out these dreams. While a person needs all the stages of sleep, deep sleep is especially important for brain health and function.
Deep sleep helps the brain create and store new memories and improves its ability to collect and recall information. This stage of sleep also helps the brain rest and recover from a day of thinking, allowing it to replenish energy in the form of glucose for the next day. Deep sleep also plays a role in keeping the hormones balanced. The pituitary gland secretes human growth hormone during this stage, which helps tissues in the body grow and regenerate cells.
Importantly, a person has to get enough deep sleep for these functions to take place. The amount of deep sleep that a person has will relate to how much overall sleep they get. Sleeping 7 to 9 hours is the recommendation for most adults, which will usually give the body plenty of time in the deeper states of sleep. If the body does not get enough deep sleep one day, it will compensate the next time it can get sleep by quickly moving through the cycles to reach the deepest levels of sleep faster and stay there longer.
However, if the person regularly does not get enough deep sleep, this may start to affect the brain. As deep sleep plays a role in memory, the body may have difficulty making new memories or retaining information if it does not get enough sleep. As the American Sleep Association note, the most important thing that a person can do to increase the amount of deep sleep that they get each night is to set aside more time for sleep. Doing so allows the body to go through more sleep cycles, which makes it possible to have more deep sleep.
Additionally, some antidepressants may help people get deeper sleep, although this is not the case for everyone. Pink noise is random noise with more low-frequency components than white noise. A study in the journal Frontiers in Human Neuroscience looked into the effects of using sound stimulation, such as pink noise, on deep sleep. There may be some ways to promote deeper sleep, such as tiring the body through exercise or listening to pink noise while falling asleep. The best way to get more deep sleep may be as simple as setting aside more time to sleep each night.

What is REM sleep?
In fact, while you're getting your zzz's, your brain goes through various patterns of activity. Stage One: Within minutes sometimes even within seconds! This introduction to sleep is relatively brief, lasting up to seven minutes.
Our bodies require sleep in order to maintain proper function and health. In fact, we are programmed to sleep each night as a means of restoring our bodies and minds. Two interacting systems—the internal biological clock and the sleep-wake homeostat—largely determine the timing of our transitions from wakefulness to sleep and vice versa. These two factors also explain why, under normal conditions, we typically stay awake during the day and sleep at night. But what exactly happens when we drift off to sleep?
How to Extend Your REM Cycle
How much sleep do we need and why is sleep important? Most doctors would tell us that the amount of sleep one needs varies from person to person. We should feel refreshed and alert upon awakening and not need a day time nap to get us through the day. Sleep needs change from birth to old age. Learn more about the importance of sleep and understanding the sleep stages. Might you have a sleep disorder? There are over to choose from. Most of us take sleep for granted until we get too much, too little or when things go bump in the night.
REM, Light, Deep: How Much of Each Stage of Sleep Are You Getting?
When you sleep, your body rests and restores its energy levels. However, sleep is an active state that affects both your physical and mental well-being. A good night's sleep is often the best way to help you cope with stress, solve problems, or recover from illness. Vivid dreams tend to occur during REM sleep.
That being said, most of us have different sleep phases each night. Most people would attribute the quality of their rest to what kind of sleeper they are. This brings us to light sleep vs.
Understanding Sleep Cycles: What Happens While You Sleep
Over the course of a night, you spend approximately 25 percent of sleep in REM phase. Instead, periods of REM are interspersed among the other stages of sleep as you move through a series of sleep cycles. It typically takes about 90 minutes of sleep to arrive at the first REM period. The first stop of the night in REM sleep is brief, lasting roughly five minutes.SEE VIDEO BY TOPIC: REM sleep vs. deep sleep and their importance for cardiovascular and emotional health - Matt Walker
Your brain is very active during REM sleep and it is when the most vivid dreams occur. As a precautionary measure, your brain also sends signals to immobilize your arms and legs in order to prevent you from acting out your dreams. REM sleep and deep sleep also referred to as slow wave sleep are very different stages of sleep. It precedes REM sleep in a normal sleep cycle, and unlike REM your heart and respiratory rate decrease during deep sleep. REM sleep is the time when new learnings from the day are committed to memory. Your first period of REM sleep each night usually occurs within 90 minutes of falling asleep, and only lasts about 10 minutes.
Deep vs. Light Sleep: How Much Do You Really Need?
Created for Greatist by the experts at Healthline. Read more. Ah, sleep. Experts say 7 to 9 hours per night is the sweet spot — and while this sounds easy enough in theory, the reality is that life work, errands, happy hour, family time can easily get in the way of that necessary shut-eye. After all, sleep is more than just a luxury — it plays a crucial role in helping your body function at its best. And not all sleep is quality sleep, either.
Some people require a solid twelve hours of sleep a night, while others are happy with a three hour nap. The amount required is completely dependent on who you are, and tends to be between four and eleven hours each night. However, there are two different types of sleep deep and light and you should really be getting over a certain amount of the deep kind. MORE: Why you should have a lie in on the weekends.

Does Deep Sleep Really Matter?
Waking up tired, angry, or cranky? By tapping into your nighttime heart rate and movement patterns, these devices will be able to estimate how much time you spend in light, deep, and rapid eye movement REM sleep. Pretty cool, right? Each of these stages—or sleep types—serve a different purpose, so understanding how much of each stage you log can help you identify and address sleep-related issues.

Sleep is an important part of your daily routine—you spend about one-third of your time doing it. Quality sleep — and getting enough of it at the right times -- is as essential to survival as food and water. Sleep is important to a number of brain functions, including how nerve cells neurons communicate with each other. In fact, your brain and body stay remarkably active while you sleep.
