How much rem deep sleep do i need
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. Both are exactly what they sound like—your eyes either remain still or move rapidly under your eyelids. Together, these two types of sleep make up a single cycle where your brain progresses sequentially through each stage of sleep: wake, light sleep, deep sleep, REM, and repeat.

Natural Patterns of Sleep
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. You may start to relax and dream, but may also twitch as you transition into stage 2. Stage 2 of the sleep cycle is still a light sleep, but you are drifting into a steadier sleep.
Your breathing and heartbeat slow down, and your muscles relax. Your body temperature decreases, and your brain waves are less active. In stage 3, you enter deep sleep, and stage 4 is the deepest sleep stage.
During deep sleep, your breathing, heartbeat, body temperature, and brain waves reach their lowest levels. Your muscles are extremely relaxed, and you are most difficult to rouse.
Stage 4 is known as the healing stage, when tissue growth and repair take place, important hormones are released to do their jobs, and cellular energy is restored. Your first REM cycle of the night begins about 90 minutes after you fall asleep and recurs every 90 minutes. Your eyes move around quickly behind your eyelids and your brainwaves look similar to those of someone who is awake. Your breathing, heart rate, and blood pressure rise to near-waking levels. REM sleep, often referred to as stage 5, is when you are most likely to dream.
Your arms and legs become temporarily paralyzed during this stage to prevent you from physically acting out your dreams. In healthy adults, about 13 to 23 percent of your sleep is deep sleep. However, as you get older you require less deep sleep. Without deep sleep, these functions cannot take place and the symptoms of sleep deprivation kick in. Experts believe that dreaming helps you process emotions and solidify certain memories.
For most adults, REM takes up about 20 to 25 percent of sleep, and this seems to be healthy during average sleep cycles. However, sleep research is raising some interesting questions. One recent study suggested that higher amounts of REM sleep may be associated with depression.
Although sleep scientists believe that light sleep is good for you, there is no minimum to strive for. Light sleep is usually the default stage, one that is nearly impossible to avoid if you are asleep at all. Too much overall sleep on a regular basis, however, is linked to obesity , depression, pain, heart disease, and even increased risk of death. Babies and children need more sleep than adults. Babies need the most, spending about 16 of every 24 hours asleep. Approximately 50 percent of their slumber is spent in the REM stage, while the other 50 percent is divided between stages 1 through 4 and NREM sleep that cycles between light and deep.
These include:. Although the science is still new, a number of sleep trackers are available that may help you track your sleep patterns and see how much light, REM, and deep sleep you are getting. A sleep study may help you figure out what is going on. Scientists say that quality sleep is as important to health as food and water are. It helps you to survive and thrive. Some of the side effects of sleep deprivation include:.
Scientists agree that sleep is essential to health, and while stages 1 to 4 and REM sleep are all important, deep sleep is the most essential of all for feeling rested and staying healthy.
The average healthy adult gets roughly 1 to 2 hours of deep sleep per 8 hours of nightly sleep. There are various ways to gauge whether you are, from personal trackers to a sleep study.

Brain Basics: Understanding Sleep
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.
There is an abundant amount of research on deep sleep, but we have all of the essential information you need to know on what it is, its function, and how you can get more of it. Deep sleep is the sleep stage that is associated with the slowest brain waves during sleep. Because the EEG activity is synchronized, this period of sleep is known as slow-wave sleep: it produces slow waves with a relatively high amplitude and a frequency of less than 1 Hz. The initial section of the wave is indicated by a down state; an inhibition period whereby the neurons in the neocortex are silent.
REM, Light, Deep: How Much of Each Stage of Sleep Are You Getting?
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. Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake. Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body — from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity. Sleep is a complex and dynamic process that affects how you function in ways scientists are now beginning to understand.
What to know about deep sleep
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. This is divided into three stages, with each becoming progressively deeper. NREM3 becomes deeper, and if woken up, we can feel disorientated.
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.
How Much Deep Sleep Do You Need?
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.
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. Usually, REM sleep occurs 90 minutes after sleep onset. The first period of REM typically lasts 10 minutes, with each recurring REM stage lengthening, and the final one lasting an hour.
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?

I tend to over-caffeinate in the mornings and use that fuel to power through the day. When I get home I start the process all over again. Working in the sleep space has made me hyper-aware of just how poor my sleep habits really are.
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. But all that data only makes sense if you know what you're aiming for and what it all means. Here's how to decode your sleep cycles so you can make the most of your shut-eye.
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.
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.
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.
