The importance of REM sleep: Special Ideas
On average, adults spend around 1.5 hours of their 8-hour sleep cycles in the REM (rapid eye movement) sleep state. Rapid eye movement (REM) sleep is sometimes referred to as paradoxical sleep due to the neurological and physiological similarities it shares with awake. Nonetheless, this is the deepest stage of sleep and maintaining optimal brain function at this time is of highest importance.

What Exactly Is Rapid Eye Movement Sleep?
Mnemonic device for the abbreviation of “rapid eye movement,” or REM. Your eyes will be swiftly moving back and forth when you enter this stage of sleep, thus the name. During rapid eye movement (REM) sleep, blood supply to the brain decreases while it increases to the muscles. Around 80% of dreaming, it is thought, occurs during rapid eye movement sleep. The onset of REM sleep, sometimes known as “dream sleep,” occurs a while after one has fallen asleep. REM sleep is crucial, and it plays a crucial role in maintaining a healthy brain.
Time in bed and dreaming
The most beneficial part of sleep for the brain is the rapid eye movement (REM) stage. Usually, a person will go through around three stages of non-REM sleep before entering REM sleep. To help keep your circadian rhythm steady, this cycle is crucial. If your REM sleep is interrupted, the next night you may go straight into REM sleep instead of following the typical sleep pattern. This might lead to the tiredness, drowsiness, and lack of concentration that often accompany sleep deprivation.
Cycles of Sleep’s First Stage
We’re now in the midst of the change. The space between being awake and asleep. The heart rate, breathing rate, and eye movements all decrease, and the muscles loosen up and perhaps twitch very little. Moreover, the brain’s waves decelerate down.
The second phase, “light,” is the name given to this phase. It’s a rather restful period of sleep. The body’s temperature declines, muscular activity slows, and brain waves become more regular, with the exception of transient spikes of electrical activity.
We’ve reached the third and last stage of slow wave sleep. Your muscles will be the most relaxed and your heart rate will be the slowest during this stage of sleep. As the name implies, this is a more profound stage of sleep. Someone at this stage of sleep may be difficult to awaken.
Profound Sleep This is the deepest stage of sleep, and although it’s similar to stage 3, it’s distinguished by even less brain activity and a drastically slowed heart rate and breathing rate.
Characteristic jerking of the eyes during sleep is a telltale sign of REM sleep stage five. The brain’s waves start to look more like those observed while awake. The most of our lucid dreams occur here. A defensive mechanism kicks in when your heart rate quickens and your muscles tense up to stop you from acting on your dreams.
