REM Sleep vs Deep Sleep — How Do They Work?
All sleep is not the same. You've probably heard about light sleep and deep sleep, and many often equate deep sleep with REM sleep. Just as.and
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.
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. 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.
In late December of , scientist Eugene Aserinksy inadvertently discovered REM sleep on the second floor of Abbot Hall at the University of Chicago, effectively changing our entire understanding of how sleep works. What are the stages of REM sleep? The first four stages involve transitionary periods between shallow and deep sleep, but when REM kicks in, the brain experiences heightened activity and heart rate increases. Oddly, despite their numerical order, sleep does not actually progress linearly through the stages. The first 4 stages of sleep are categorized based on characteristics of the body and brain during sleep. Brainwave frequencies differentiate each stage, along with other biologic rhythms. Stage 1 is the lightest stage of sleep — falling asleep, but not quite there yet.
“If deep sleep is about body, REM is about the brain,” says Grandner. “The brain is very active during REM sleep, yet the body is very inactive.

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.

Follow Metro. Tips for getting more deep sleep Get into a better bedtime routine , switching off from screens and work and giving yourself enough time to fully relax before bed. Stay warm but not too warm.
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. In the app, your sleep will fall into three stages: light, deep, and REM.
REM, Light, Deep: How Much of Each Stage of Sleep Are You Getting?
Being awake is a state of consciousness accompanied by heightened perception, realistic thinking, environmental responsiveness and physical activity. In contrast, sleep is a behavioral state of decreased perception, relatively low responsiveness to the environment and physical inactivity or rest. A quiescent body is the most obvious characteristic of sleep, but the brain remains active at varying levels while regulating sleep and performing vital tasks.

Just as light and deep sleep are different from one another, REM and deep sleep are two completely different sleep stages, each with defining characteristics. REM and deep sleep are stages three and four of sleep. Rapid eye movement, or REM sleep, is the deepest sleep stage. The eyes move more rapidly in all directions during REM sleep, a s its name indicates. REM is the fourth stage of sleep.
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. Humans sleep in cycles. The best known is REM, which stands for rapid eye movement, because your eyes move rapidly during this stage of sleep.
