Do You Get Full Sleep Cycles? Sleep Scientists Explain Why It’s Good For Your Health


When you sleep, your brain goes through two phases. One is called rapid eye movement (REM) sleep and the other is called non-rapid eye movement (Non-REM) sleep. Your brain will go through REM and non-REM sleep several times each night. Here’s what sleep specialists say you should know about these two sleep cycles.

What is REM sleep?

REM sleep begins about 90 minutes after falling asleep. It lengthens as the night progresses. REM sleep has these characteristics.

  • Your body and brain are stimulated.
  • Your breathing becomes irregular and faster.
  • You dream because your brain is more active.
  • Your eyes will move from side to side.
  • The body relaxes and becomes immobile, so you do not represent your dreams.
  • His body temperature drops slightly.

Different regions of your signals receive when REM sleep begins. The cerebral cortex of your brain allows you to learn, think, and organize thoughts. The signals go to the spinal cord to slow down movements, so the muscles in the arms and legs cause temporary paralysis, so that it does not move. During REM sleep, you store memories, learn, and moods are balanced. REM sleep generally occurs at intervals throughout the night.

Usually every 90 to 120 minutes, you go in and out of REM sleep. You dream during REM sleep, but it can sometimes happen during Non-REM sleep. As you get older, you have less REM sleep.

What is non-REM sleep?

There are three stages of non-REM sleep, according to the Cleveland Clinic team. Here is a breakdown of each stage.

  • Stage 1: In this stage, you are between being awake and beginning to fall asleep. The breathing and heartbeat slow down and the muscles begin to relax. This stage usually lasts 5 to 15 minutes.
  • Stage 2: In stage two, you are a light sleeper. Brain waves begin to decrease and body temperature drops. This stage lasts between 10 and 25 minutes.
  • Stage 3: During stage 3, you are in your deepest and most restful sleep. At this point, the heartbeat and breathing are very slow. Your muscles are completely relaxed. Then your body begins to repair tissue and sends blood to your muscles. Your energy is renewed. Your body also releases hormones. When you wake up during this phase, you will feel disoriented for several minutes until you are fully awake.

How much do you need to sleep?

Your sleep patterns change as you age. Babies need 16 to 18 hours of sleep per day for good growth and development. Primary school children need 91/2 hours of sleep. Studies show that most adults need 7 to 9 hours of sleep each night. After age 60, you tend to sleep less with lighter and more interrupted sleep at night. The idea that you can regain sleep on the weekends is a fallacy because you can’t really catch up if you’re not sleeping on weeknights.

What if you don’t get enough REM and Non-REM sleep?

Sleep studies show that REM sleep is important for your functioning during the day, especially for learning, memory, or learning a new skill. REM sleep also improves your ability to solve problems. Lack of REM sleep can affect your mood. Mood disorders such as depression, anxiety, or post-traumatic stress disorder (PTSD).
