More about sleep cycles! Talk about the best time to wake up and the importance of sleep
There are 2 “modes” of sleep: Slow wave sleep and REM sleep.
Slow Wave Sleep is super deep and is hard to interrupt. When you wake up during this phase, you don’t feel rested and are tired for the rest of the day.
REM sleep is lighter sleep, so it can be easily interrupted. A bonus to waking during a REM phase: remembering your dream and feeling energetic.

Edit: I want to make a comment on the graph:
- During the pink “awakening” times is when your REM cycle ends. That’s when you wake up in the middle of the night for a couple minutes and then fall back asleep
- REM Cycles repeat roughly every 90 minutes, but it may vary slightly. If you wake up during the REM phase, you’re guaranteed to feel more energetic even if you slept a bit less than recommended (8 hours)
