3 important ways that sleep keeps the brain healthy, from thesleepdoctor
trash bin, moves memories from short-term to long-term storage, and helps our brains better process emotional situations.
What the researchers found was that during non-REM sleep, slow waves of cerebrospinal fluid, a clear, watery liquid, would essentially wash over the brain. This process occurred when neurons started to sync up during non-REM sleep, turning off and on in unison; when the neurons weren’t firing, they didn’t need as much oxygen as usual, meaning less blood would enter into the brain., like beta-amyloid.
Without sufficient non-REM sleep, those proteins aren’t removed and remain in the way of the brain functioning efficiently. That’s why your brain isn’t as sharp after a rough night of sleep — the brain hasn’t dumped the trash, so to speak, which ends up making it tougher for your mind to quickly fire away. Sleep helps remove the daily clutter and gives you a clean start the following day.It might feel like it sometimes, but your brain doesn’t just shut off while you’re resting.
