Sleep Cycle
Sleeping is not as simple as it seems. As we close our eyes and fall asleep there is so much going inside than what it seems to the outer world.
Sleep cycle: There are 5 stages in every cycle and each cycle last around 90 minutes. The first four stages make non-rapid movement of eyes (NREM) and the fifth stage is when there is rapid movement (RME) of eyes.
NREM Stage:- The non-rapid eyes movement starts from the beginning of the first stage up to the fourth stage it is very. It is very difficult to wake someone who is in Stage 4 sleep. Across NREM sleep, we have little muscle activity and our eyes do not typically move, but all of our muscles retain their ability to function.
REM Stage:- As the name would imply – during this final stage of sleep, we have bursts of rapid eye movements. This is the stage of sleep in which most dreaming occurs. Our eyes are not constantly moving, but they do dart back and forth, up and down. These eye movements may be related to visual images of dreams, but that is not confirmed, and in general, the reason for these eye movements is still a mystery. Although our eyes are moving rapidly, the muscles that move our bodies are paralyzed (other important muscles, such as our heart and diaphragm continue to function normally).
where can you use sleep cycle?
Giving yourself a full sleep cycle (90 minutes) can help you retain certain skill you’ve just learned, but for recovering from fatigue a 15-20 minute nap is ideal (and some research suggests a nap as short as 5 minutes could be beneficial!), since the farther along you are in your sleep cycle, the harder it is to get over that grogginess you sometimes feel when you first wake up (known in the sleep world as sleep inertia).
