This next stage is the transition period between being awake and being asleep, and it usually doesn’t last more than 10 minutes. You can sort of think of the wakefulness stage as “Stage 0” because, well, you’re awake! It may not seem important for our purposes, but in fact, wakefulness and sleep are intertwined - when you're awake, your brain and body use up energy and other resources that are then replenished during sleep. So how do REM and non-REM sleep relate to our sleep stages?Īccording to the American Association for Sleep Medicine, there are five stages of sleep, with the first four falling under the non-REM sleep category: 1. It’s during non-REM sleep that you’re more likely to get woken up. Non-REM sleep, however, is almost the exact opposite: your brain is relatively inactive, but your body is still moveable to a certain degree depending on whichever sleep stage you’re in. What Are the Different Sleep Stages?įirst things first, we need to talk about REM sleep and Non-REM sleep.ĭuring REM sleep, your brain is active but your body is paralyzed, and your eyes randomly dart around underneath your lids (as you may know, “REM” stands for “rapid eye movement”). But, those hours won’t mean much if your sleep stages and sleep cycles are out of whack. But how many of us know the average number of sleep cycles we need each night?Īfter all, most of our sleep education has been centered around hours - infants need 14–17 hours, kids need 10–13 hours, teens need 8–10 and adults need 7–9. Most of us have a pretty good idea of how many hours of sleep we need each night.
