I always knew Mother said to get enough sleep. But other than to avoid being cranky and drowsy like a zombie the next morning, I didn’t get what the big deal was. But the reason our bodies need sleep is more complicated than just a matter of having energy the next day. In fact, it’s a very fascinating and complex science.

Did you know that when you sleep, your brain picks and chooses which memories it’s going to keep and which ones it will throw away?

Did you know that your brain has a sewage system, preventing the build-up of a certain chemical that causes dementia? But that sewage system is only activated once you reach a certain stage of sleep, meaning you have to get enough hours of sleep for it to work?

I know, I was mind-boggled when I heard about all this too! I stumbled across the Fresh Air radio program during this interview with a sleep scientist, and knew I had to share it here with you all. The reason for more sleep is making more sense. The interview goes into greater depth on the subject, and also discusses the impact of caffeine on sleep, and the science fiction possibility of us one day being able to erase memories! (How crazy is that?)

  1. Wow that’s CRAZY! I’m sure I’ve heard these before but they never cease to astound me :D. Your brain chooses what memories to keep! xD Forget the traumatizing things!

    • Exactly, right? If only our brains would listen to what memories we do and don’t want to keep. 😀 Yeah, some of this we’ve all heard before, but there’s a lot of new things scientists have learned just recently, which is what made this podcast cool to listen to. Plus, plenty of fodder for possible sci-fi / futuristic story plots! 😉
