If You Don’t Wake Rested After a Full Night of Sleep…
Sometimes, the problem with our sleep habits is that our body and mind aren’t falling deep enough into sleep. Sleep is something that happens in cycles, including wake, N1, N2, N3, and REM. As you move through the stages, you fall deeper asleep. The “N” stages are non-rapid eye movement sleep, so they do not provide the same quality of sleep as REM (rapid eye movement) stage.
Reaching REM is important for waking fully rested. The REM stage is when your body is at ideal rest when it can store memories and consolidate what you’ve learned throughout the day. This is also the stage when you dream. Interestingly, the amount of REM sleep that you need each night varies based on your age and how much you learned.
