In the deep sleep phase, even though the eyelids are closed, the eyes do not stop moving and continue to move during sleep.
Researchers have not agreed on the reasons for this phenomenon yet. Some experts believe that eye movement is associated with a widespread nerve stimulation in the brain, and brain activity is so intense in a way that it allows the body to organize memories and classify information.
For this reason, our body needs calm physiologically, deep, and regenerative sleep.
All of us will rise during the night. In fact, the spine is relaxed slightly overnight for its softness, and this also leads to increasing size of the intervertebral discs, and eventually we grow a few millimeters and get taller at night.
Of course, the discs will return to their original state with the beginning of the day and we will find our normal height.
