Why We Sleep: Unlocking the Power of Sleep and Dreams
by Matthew Walker
NREM sleep for learning. NREM unqiue to higher animals,
REM sleep common in all animals. Emotional regulation. Removing the emotional edge of memories and allowing coping to happen. Without REM sleep death occurs as if there was total sleep deprivation, which happens at 3 weeks.
Dreaming about events with the negative emotions associated with real life experiences helps release the emotional power of those experiences, and allows healing.
Adults need 8-9 hours of sleep. Especially in the early mornings.
