How much rem sleep do we need each night
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.SEE VIDEO BY TOPIC: Sleep: What's REM Got to do With It

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. The final one may last roughly an hour. If you get hours of sleep, around 90 minutes of that should be REM. As mentioned above, not getting enough REM sleep can negatively impact your brain's ability to learn and create new memories. Additionally, because the majority of your REM sleep tends to come towards the end of your night in bed and after deep sleep, which your body prioritizes when it needs to catch up on sleep , a lack of REM is often a sign of sleep deprivation.
Chronic sleep deprivation has been linked to greater risk of obesity, Type 2 Diabetes, dementia, depression, cardiovascular disease and cancer.
There has also been research to show that insufficient REM sleep may cause migraines. Overall, whatever you can do to improve your sleep habits and behaviors will also help you get more REM sleep. This begins with simply making an effort to spend more time in bed. Here are 45 tips to help you sleep better.
There are also two other things in particular that stand out with how to increase REM sleep. The first is a concept we refer to as sleep consistency --going to bed and waking up at the same time each day or as close to that as possible. Your body functions more efficiently when it is on a regular schedule, and this applies to sleep as well. We ran an analysis of sleep data from 25, WHOOP members, and the results showed a significant rise in the nightly amount of REM sleep as the percentage of sleep consistency over a 4-day span increased:.
The second big thing is to stay away from alcohol before bed. When your body is forced to process alcohol during sleep, it has difficulty getting past light sleep and into the deeper stages. The WHOOP app also features a Sleep Coach that uses your own circadian rhythm to recommend daily bed and wake times to optimize the quality of your sleep.

What is Sleep and Why is It Important?
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.
The quality of your sleep directly affects your mental and physical health and the quality of your waking life, including your productivity, emotional balance, brain and heart health, immune system, creativity, vitality, and even your weight. No other activity delivers so many benefits with so little effort! But even minimal sleep loss can take a substantial toll on your mood, energy, mental sharpness, and ability to handle stress. And over the long-term, chronic sleep loss can wreak havoc on your mental and physical health.

Natural Patterns of 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.
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.
What to know about deep sleep
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.
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. Below, a breakdown of what you need to know about each sleep stage. Sleep researchers divide sleep into five stages—stages 1, 2, 3, and REM—but to keep things simple, Fitbit groups like sleep stages together.
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.

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?
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.

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. Here, you are in light stage sleep, which means that you're somewhat alert and can be easily woken.
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.
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.

Your first period of REM sleep each night usually occurs within 90 minutes of falling asleep, and only lasts about 10 minutes. The final one may last roughly an hour.
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.
