Sleep cycles through these stages approximately 4 or 5 times throughout the night. We typically enter REM approximately 90 minutes after falling asleep. The first cycle of REM often lasts only a short amount of time, but each cycle becomes longer. This is why we need long periods of sleep each night. If we get short periods of sleep, we canât really get through the stages we need to heal and stay healthy. REM can last up to an hour as our sleep progresses. In case you are wondering, if you feel like a dream is taking a long period of time, it really is.
If sleep is mysterious, REM sleep is even more mysterious. REM phemonmena has wormed its way into folklore over the centuries because the brain is active and the skeletal muscles have no tone. The muscles associated with breathing are not paralyzed, but breathing in REM is shallower and more rapid.he first REM period happens 70 to 90 minutes after sleep onset. At first these REM episodes are short (a few minutes), but as the night progresses, they become longer. Most REM sleep is late in the main sleep period (close to morning). A typical adult spends about an hour and a half every night in REM.
