REM sleep also helps the mind recover from distressing experiences by suppressing them. Emotion regulation and memory consolidation are processes that take place during this stage. At times, your brain can be more active during REM sleep compared to when you are awake. Also, in REM sleep, your brain becomes highly active and functions at levels that are more similar to when you are awake. Breathing rate, heart rate, and blood pressure rise during this stage. REM sleep is sometimes referred to as paradoxical sleep because it has similarities to being awake. The American Sleep Association says that three things primarily occur during REM sleep: dreams, limited or no muscle movements (known as muscle atonia, and it happens, so we don’t act out our dreams), and rapid eye movements. It starts about 90 minutes after falling asleep. REM sleep is the sleep stage where most of our dreams happen. The NREM stages account for about 75% to 85% of your sleeping time, with the remaining 20% to 25% is spent in REM sleep. NREM-3 is more common during the 1st half of night, and REM is more common during the 2nd half of the night. We cycle through sleep stages multiple times as the night goes on, approximately in 90-minute timespans. Body temperature and heart rate are usually at their lowest, and the brain exhibits what are known as “slow waves” of activity which is why NREM-3 is sometimes referred to as “slow-wave sleep”.Įxperts agree that all the sleep stages are important for maintaining healthy sleep, each stage for different reasons. This is the deepest NREM sleep stage and it’s more difficult to wake someone up during this stage. Stage 3 NREM sleep: Also known as deep sleep, this stage is essential for brain and body recovery, growth, and immunity.Brain wave activity also slows down, body temperature goes down, and eye movements stop. Your heartbeat and breathing continue to slow down while your muscles relax. Stage 2 NREM sleep: This is a light sleep stage that takes you into.Brainwave activity and eye movement also reduce during this stage. Most people spend the least amount of time in NREM 1. During this sleep stage, the muscles start to relax, heartbeat lowers, and breathing rate reduces. Stage 1 NREM sleep: This is the shortest and lightest sleep stage where people can be easily awoken during the night.NREM sleep is further subdivided into three sleep stages: These sleep stages generally consist of two broader states: non-rapid eye movement (NREM) sleep and rapid-eye-movement (REM) sleep. What are the different stages of sleep?Įvery night when you go to sleep, your brain takes you through cycles of different sleep stages throughout the period you’re asleep. So, what is REM sleep, and how is it linked to dreaming? What stage of sleep do you dream? Can you dream in all sleep stages? Does dreaming mean you’re getting good sleep? Read on to learn answers to these questions. If this has happened to you, chances are you were woken up during a period of REM (rapid-eye-movement) sleep. After you woke up, you might have even found yourself feeling disappointed that you could not finish your dream. Have you ever woken upright in the middle of a peaceful or exciting dream?
