Steven Weiniger  Everyone knows sleep is important, but until recently no one knew exactly why.
Now research shows that waste products from the brain’s metabolism accumulates in the fluid surrounding nerves during the day, and then gets flushed out and eliminated when you sleep. The fluid is called cerebro-spina fluid (CSF), and the study found poor sleep was associated with a buildup of a substance (b-amyloid) in CSF associated with Alzheimers. |
