Sleeping pills stop the brain’s system for cleaning out waste

arstechnica.com Sleeping pills stop the brain’s system for cleaning out waste

A specialized system sends pulses of pressure through the fluids in our brain.

Her study found the glymphatic clearance was mediated by a hormone called norepinephrine and happened almost exclusively during the NREM sleep phase. But it only worked when sleep was natural. Anesthesia and sleeping pills shut this process down nearly completely.

I wonder what melatonin does
- It's a natural hormone brain produces that signals to the body that it's zzz time.
  
  I love it for bedtime and it helps my autoimmune shit. Glad it's not brain bad.
  
  Aside from possibly becoming a dependency, I'd imagine it doesn't interfere with sleep quality. It's what builds up in your body to make you sleepy/fall asleep.
  Too much might keep you groggy in the morning though.
- Forget melatonin, I want to know wtf cheese is doing to my brain when I sleep on it.
  
  Probably just stick to the side of your head.
  Have you tried eating the cheese instead?
  
  Charlie Kelly... who taught you about Lemmy?
  
  Im pretty sure cat food and spray paint shut down m9re than just the NREM cycle in the brain...
