Non-REM sleep makes up the vast majority of the sleep cycle-three out of the four stages. NREM and REM sleep are two very different phases of the sleep cycle, but each phase has its own benefits. REM sleep can also re-energize your mind. In addition, your muscles may be immobile to prevent your body from reacting to dreams, which primarily occur during REM sleep. REM sleep is when your respiration speeds up and your heart rate increases. This stage is marked by your eyes moving rapidly beneath your eyelids, thus the rapid eye movement moniker. REM Sleepįinally, the last stage of the sleep cycle is the REM stage. Your brain activity will also exhibit long, slow waves and flush waste out. If you do wake up, you’ll likely feel more groggy or disorientated.ĭeep sleep allows your body to grow and repair muscle. During deep sleep, you’re less likely to wake up from environmental noise or light. Your heartbeat and breathing will be at their slowest, and your body will be at its most relaxed. Deep sleep is when your body and brain really repair themselves. The third stage of sleep, deep sleep, is an NREM stage. It’s easier to wake up out of this stage of sleep as compared to deeper sleep.ĭreaming can occur in this stage of NREM sleep, but these dreams are shorter and simpler in comparison to the more vivid dreams that happen during REM sleep. In this stage, your body temperature will also begin to drop.ĭuring this stage of the sleep cycle, you’re sensitive to changes in noise, touch, temperature and light. Your breathing rate slows down, and brain activity continues to change. As you enter this deeper part of the sleep cycle, your muscles continue to relax, and your heartbeat continues to slow. The next stage is light sleep, which is another NREM stage of sleep. In the first stage, you slow your heart and breathing, you relax your muscles, and your brain begins to ready itself for sleep. This stage can also include any periods of awakening you have throughout the night. Your awake state is when you’re lying in bed at night and when you’re lying in bed in the morning before waking up. This NREM stage is the lightest stage of sleep. The first stage of sleep is the awake stage. The first three phases of sleep are considered NREM, while the final stage of sleep is REM. Each stage of sleep is also categorized as a non-rapid eye movement state (NREM) or a REM state. Each stage is important and is necessary to make you feel healthy and restful the next day. These sleep stages can be categorized as awake, light sleep, deep sleep, and rapid eye movement (REM) sleep. These four stages-each lasting about 90 minutes-will cycle throughout the night until you wake up for the day. Each stage does something different to your body and your brain. When you go to sleep, you’ll go through four stages. ![]() This is why we get tired at night and are alert during the day. This is your body’s natural clock, and it sets itself based on several environmental factors, namely light. Your brain also regulates sleep through your circadian rhythm, also known as your sleep-wake cycle. Once you’ve given your body and brain the rest it needs, your sleep drive is reset, and you’re back to normal wakefulness. The longer you’re awake, the higher your sleep drive gets. ![]() For most people, this drive is fairly easy to predict. Your homeostatic sleep drive is your body’s natural inclination to want sleep after you’ve been awake for a certain period of time. Your sleep schedule and regulation are determined by two processes: your homeostatic sleep drive and your circadian rhythm.
