![]() ![]() As most REM occurs during your later sleep cycles, you sometimes feel like you’ve just been dreaming when you wake up. REM is the stage where you do most (but not all) of your dreaming. ![]() During the night, you will experience multiple cycles of sleep, flowing through each of these stages during each cycle, with REM coming last after the light and deep sleep of NREM. REM is one of the four sleep stages, with the others being non-REM (NREM) stages 1-3. For most adults, it’s usually around 90 minutes, but this doesn’t happen all at once but during different cycles of your sleep. ![]() The amount of REM sleep we have each night varies throughout our lives. But as your cycles continue, your REM sleep will get longer until your last cycle, which typically lasts around an hour. How much REM sleep do you need?ĭuring your first sleep cycle each night, your REM stage will be short, lasting only a few minutes. That is why having adequate rest after a stressful day is an integral part of your recovery process. However, research has shown that REM sleep helps you heal from traumatic experiences by suppressing troubling memories. This movement of your eyes behind your eyelids, the increased speed of brainwaves, and temperature fluctuations are why some scientists call REM “active sleep.” However, during this stage of sleep your muscle activity is suppressed, so you remain physically relatively still. REM is the unique fourth stage of sleep characterized by rapid eye movement (hence the name) and brain activity patterns similar to when you are awake. During this sleep stage, your brain transfers short-term memories from your motor cortex to your temporal lobe, ensuring they become long-term memories. REM is essential for your mental and emotional recovery. In this blog, we’ll look at how and why it occurs, how much you ideally need each night, and what happens if you experience too much REM sleep. REM sleep happens every night, but several factors can affect the amount you experience.
