Sleep cycles are an interesting topic to research in depth of you have the time. Studies have shown the quality of our sleep directly impacts our daytime productivity levels. But its information that’s universally known.
What may not be common knowledge is that we all go through sleep cycles each night and that a good night sleep hinges on us completing each cycle we start in full. For example there are 4 stages of our sleep cycle: Light Sleep, Moderate Sleep, Deep Sleep, and REM (Rapid Eye Movement).
Each stage has its own traits that we experience. We need to experience each stage for one sleep cycle to be complete. On average we go through a total of 4 to 6 cycles a night each averaging about 90 mins. The trouble starts when we wake up in the middle of a stage, leaving a cycle incomplete.
If you’ve ever wondered why you accomplished the recommended 7 to 8 hours of sleep but still felt groggy in the morning, you probably woke up in the middle of stage 2 or 3.
There are hundreds of other cycles in our lives I could use to backup the main point of this post which is: cycles need to be completed in full for us to benefit from them. Even when we decide to close a business, or quit a project, drafting a ‘post mortem’ to review what went wrong is good practice to ‘close the loop’.
