You may have heard that adults need between 7 and 9 hours of sleep each night. But, the quality of sleep you get also matters. While you rest, your body goes through different stages of the sleep cycle. Deep sleep, for example, is the stage of sleep you need to feel refreshed when you wake up in the morning. Unlike rapid eye movement REM sleep, deep sleep is when your body and brain waves slow down.

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. How do we dream and what exactly are nightmares?

What is REM sleep?

Sleep Basics

Each night you take a rollercoaster ride through the different phases of sleep. Each cycle plays an essential role in maintaining your mental and physical health. The amount of each phase of sleep can vary significantly between nights and individuals.

Now more than ever, we can quantify exactly how good or bad our sleep patterns are. Each morning you can review your heart rate, breath rate and sleep graphs with information about how much light, deep and REM sleep you had the night before.

There are five stages of sleep that rotate between non-rapid eye movement NREM and rapid eye movement REM and include drowsiness, light sleep, moderate to deep sleep, deepest sleep, and dreaming. Experts have recommended that adults gets about 7 to 9 hours of sleep per night. New research aims to identify not just how much total sleep you need — but also how much of each stage of sleep you need. Sleep stages 1, 2, and REM consist of light sleep, while 3 and 4 comprise deep sleep. During stage 1, you drift from being awake to being asleep.

What to know about deep sleep

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. Other neurons at the base of the brain begin signaling when we fall asleep. Research also suggests that a chemical called adenosine builds up in our blood while we are awake and causes drowsiness. This chemical gradually breaks down while we sleep. During sleep, we usually pass through five phases: stages 1, 2, 3, 4, and REM rapid eye movement sleep.

What is Sleep and Why is It Important?

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.

According to the National Sleep Foundation , research shows that most adults need 7 to 9 hours of sleep each night. But other findings suggest that the type of sleep we get is more important than the duration of our sleep. When we sleep, our body goes through five specific stages as noted by he National Institute of Neurological Disorders and Stroke. Each stage cumulates to REM rapid eye movement sleep, and then restarts, completing one cycle.

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.

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. Meanwhile, proclaimed deep sleepers could sleep through a screaming baby using a jackhammer. But everyone experiences both light and deep sleep in their circadian rhythm. So what does this mean and what exactly is the difference between the two?

Sleep Health

Many of us would have gotten our hands on new gadgets over the Christmas period including devices like Fitbits and other smart-bands that can monitor your sleeping patterns. Part of the feedback the devices give is how much light sleep and deep sleep you are having each night. Here is everything you need to know about your sleeping pattern and how much deep sleep you should be having. A typical adult would usually benefit from have around 1. Light sleep occurs when you first nod off. It usually involves lots of movement, and is easy to wake from. When your body is finally comfortable you will fall into deep sleep.

Sep 30, - conversation with someone as they're falling asleep and see how much they remember. Sleepers who awake during REM sleep usually have a better need to ensure that you're completing at least sleep cycles a night. If you must wake up at a.m., either start going to bed at 11 p.m. or

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 much deep sleep should you get each night?

Most of us require between 90 to minutes of REM sleep each night, but it can be an elusive sleep stage to reach sometimes. Why is that? Having a few alcoholic beverages in the evening may be contributing to your lack of REM. Nicotine is another known culprit for suppressing this stage of rest according to a study.

How to Extend Your REM Cycle

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.

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.

How much sleep do we need and why is sleep important?

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.

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. Each subsequent return to REM grows longer.

The average person spends around a third of their life asleep. In this time, our bodies are able to replenish energy stores and make repairs, while our minds organise and store the memories of the day before. The amount of sleep you need depends on your age, sex, health and other elements, and sleep cycles change as we grow older.
