As you may have already guessed, quality sleep consists of being able to sleep deeply. For our minds to easily slide into the deep stages of sleep, and stay there for the time needed. Easier said than done.
So I've got a question for you: What controls how long and how deep you sleep? There's an underlying mechanism in our bodies called our “body clock”. However, I don't like the name so I will simply refer to it as the sleep clock. Your sleep clock is a system inside of you which controls how you sleep, how deep you sleep, when you sleep, and how awake you feel during the day. Once you understand this system you'll be able to take control over your sleep and your energy!
The challenge in our society is that our sleep systems have been weakened by so many outside stressors that we're not even aware of, that our sleep clocks are totally out of whack. This is why so many people can't sleep deeply, why they may suffer from insomnia, poor day-time energy levels, or find themselves waking up several times in the middle of the night. Usually when you wake up in the middle of the night it is at the end of a sleep cycle in Stage 2 or REM sleep when our brain waves are highest and we're most wakable. This happens because of a weakened sleep system.
