This Is What You Need to Know About REM Sleep
Although your sleep may seem like one linear process, nothing could be further from the truth. Each night, you go through 3 to 5 sleep cycles, each consisting of four stages. One of these is REM sleep. This phase plays an important role in processing the stimuli you experience during the day and is therefore essential. We’re happy to tell you more and share 4 facts and myths about REM sleep.


What Is REM Sleep?
Before diving into the facts and myths, let’s answer the question: what is REM sleep? REM sleep is the final stage of the four phases in a sleep cycle and follows the drowsy stage, light sleep and deep sleep. REM stands for Rapid Eye Movement. During this phase, your eyes move quickly back and forth beneath your closed eyelids. At the same time, your muscles are completely relaxed while brain activity increases. During REM sleep, the events and impressions of the day are processed. This makes REM sleep essential for memory, emotional processing and even your mood.
How Long Does REM Sleep Last?
A full sleep cycle lasts about 90 to 120 minutes, and you go through 3 to 5 of these cycles each night. The duration of REM sleep varies greatly and depends in part on how the earlier stages unfold. REM sleep can last as little as 5 minutes or as long as 45 minutes. In most cases, REM stages are shorter in the first cycles of the night and become longer in the final cycles. Now that you know the basics of REM sleep, it’s time for the facts and myths.
