Detailed explanation-1: -Why Is REM Sleep Called Paradoxical Sleep? Rapid eye movement (REM) sleep is called paradoxical sleep because it involves seemingly contradictory states of an active mind and a sleeping body.
Detailed explanation-2: -During REM sleep, brain activity increases, voluntary muscles are inhibited, and rapid eye movements and dreams occur (McCarley et al., 1995).
Detailed explanation-3: -What Defines Paradoxical Sleep? The paradox is that even though the brain is quite active during REM sleep, consuming large amounts of energy, the body remains completely inactive.
Detailed explanation-4: -The phase of sleep in which most dreams occur. During REM sleep, a person’s brain activity, breathing, heart rate, and blood pressure increase, and the eyes move rapidly while closed. The muscles in the arms and legs become temporarily unable to move.
