#REM sleep

During REM (rapid-eye movement) sleep the brain and nervous system are more active than during either wakefulness or deep sleep; the brain is active, displaying fast alpha waves and theta waves, but the body remains relatively motionless, providing rest for the body's structures and systems. REM is restorative to the brain by allowing for the replenishment of neurotransmitters like norepinephrine and serotonin. These neurotransmitters, which are stored in the brain are used up during the day, and then they are replenished during REM sleep. Increasing the amount of REM sleep by adding enough time in bed to ensure adequate sleep cycles can help to refresh neurotransmitters, which in turn help you to improve performance, mood, and personal energy. REM sleep also improves learning, memory storage, and mental organization. Studies have shown that intense periods of learning and training in our lives are usually accompanied by an increase of REM sleep. The longer we sleep, the more cycles we complete and the longer time we spend in restorative REM sleep. So get a minimum of 8 hours of sleep!
