Why do people sleep? What do we get from it? Leanne shares her thoughts on this very important activity that we can’t live without.
Topics Discussed in this Episode:
- The sleep cycle
- How sleep keeps the brain healthy
- The role of sleep in appetite regulation
- One sleep cycle is about 90 minutes. Half of that is light sleep. Of the remaining half, one quarter is deep sleep, and the other quarter is REM sleep.
- Deep sleep is where we get a lot of the physiological adaptations to exercise and cellular repair. It’s the restorative portion of sleep.
- REM stands for rapid eye movement. REM sleep is where we do our dreaming, memory consolidation, and learning consolidation. It’s a very important aspect of sleep.
- Sleep gives us an opportunity to repair and restore our body. It also gives us an opportunity to repair and restore our mind.
- Sleep also serves to flush out the brain of beta-amyloid plaques, thereby strengthening the brain and mitigating our risk of cognitive decline.
- Prioritize your sleep.
“What we tend to see, if you’ve had a very physical day, you may get more deep restorative sleep. If you’re under a lot of emotional load, you may notice that you get more REM sleep.”
“[Sleep] needs to be right up there as a non-negotiable.”
