Have you ever felt tired, even after sleeping for nine or ten hours? Sleep is something we do spontaneously and instinctively. Most of us can sleep, but not all of us sleep efficiently.
Since it's such a fundamental part of our health, it's essential to sleep efficiently. Efficient sleep is the time when you're sleeping soundly and not just tossing and turning in bed. Some people might lie in bed for nine hours but only get five hours of actual sleep.
The Rapid Eye Movement (REM) phase is the most critical part of efficient sleep. It is the sleep period when your brain processes your thoughts and memories, learning and putting them into perspective for you. REM sleep also plays a crucial role in overcoming difficult or traumatic events. So being able to enter the REM stage of sleep is important during times of crisis.
