Stages of Sleep: Your Complete Guide
All sleep is not the same. Just as light and deep sleep are different from one another, REM and deep sleep are two completely different stages of the sleep cycle , each with defining characteristics.
REM and deep sleep are stages three and four. Rapid eye movement REM sleep is the deepest sleep stage. The eyes move more rapidly in all directions during REM sleep, as its name indicates.
REM is the fourth stage of sleep. Time: REM sleep occurs approximately 90 minutes after you fall asleep. Body: Your heart beats faster, and your heartbeat will likely become irregular during REM.
Aside from this, the body is largely inactive during this sleep phase. Brain: REM sleep cycles are associated with intense brain activity. Sleepwalking and bedwetting incidents occur only during REM. REM sleep restores your brain and is important for your learning as well as your long-term memory. Length: There are different periods of REM sleep, the first lasting about 10 minutes. There are about three to five periods of REM stages per night. The length of REM stages increase throughout the night, and the final stage can be up to an hour.
Deep sleep is non-rapid eye movement NREM sleep. There are three other NREM stages as well. Other names for this deep sleep stage are slow-wave sleep, delta sleep, and N3 since this is the third stage of sleep. Time: The body enters deep sleep anywhere from a half hour to 45 minutes after falling asleep.
Body: Unlike REM, deep sleep is known for the changes in your body rather than your brain. Your breathing slows and your heart rate is regular during this stage. The muscles in your body become completely relaxed, and you typically sleep through external sleep distractions such as loud noises.
Brain: There are almost always no dreams during this period of sleep. It is during light sleep that you wake up the easiest.
The Pod uses a Thermal alarm that gradually warms or cools your bed to gently wake you up feeling refreshed. Some people may need more deep sleep than others as every sleeper is different. By following the simple steps sleep trackers suggest such as avoiding caffeine before bed, you can help regulate your sleep and improve your overall sleep health.

REM, Light, Deep: How Much of Each Stage of Sleep Are You Getting?
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.
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.
What is Sleep and Why is It Important?
All sleep is not the same. Just as light and deep sleep are different from one another, REM and deep sleep are two completely different stages of the sleep cycle , each with defining characteristics. REM and deep sleep are stages three and four. Rapid eye movement REM sleep is the deepest sleep stage. The eyes move more rapidly in all directions during REM sleep, as its name indicates. REM is the fourth stage of sleep. Time: REM sleep occurs approximately 90 minutes after you fall asleep.
Stages of Sleep and Sleep Cycles
Usually sleepers pass through four stages: 1, 2, 3, and REM rapid eye movement sleep. These stages progress cyclically from 1 through REM then begin again with stage 1. A complete sleep cycle takes an average of 90 to minutes, with each stage lasting between 5 to 15 minutes. The first sleep cycles each night have relatively short REM sleeps and long periods of deep sleep but later in the night, REM periods lengthen and deep sleep time decreases. Periods of wakefulness occur before and intermittently throughout the various sleep stages or as one shifts sleeping position.
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.
Stages of 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.
Learn More. The REM stage of sleep is unique because it's when you have your most vivid dreams. This is a crucial stage in sleep. Everybody has their own internal clock and individuals have various sleep needs. Nonetheless, there are certain factors to consider… Learn More.
Natural Patterns of Sleep
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.
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.

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.
What to know about deep sleep
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.
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.
Does Deep Sleep Really Matter?
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.
