Remember Osmosis Jones?
Tiny workers inside the body, cleaning up messes and keeping everything running behind the scenes?
Your brain actually has its own version of a nighttime cleanup crew.
It's called the glymphatic system.
During deep sleep, cerebrospinal fluid moves through brain tissue, helping clear metabolic waste, including proteins such as beta-amyloid and tau.
The catch?
This cleanup process is strongly tied to sleep, particularly slow-wave sleep.
So when you consistently cut your sleep short, fragment it, or disrupt it with alcohol, you're interfering with the shift your brain uses for maintenance.
Think of it like Osmosis Jones, except the cleaning crew works nights.
Support the night shift:
→ Keep a consistent sleep schedule
→ Keep your bedroom cool
→ Limit alcohol before bed
→ Give yourself enough time to actually sleep
→ Address frequent nighttime awakenings
Your brain does a remarkable amount of maintenance while you're asleep.
Stop sending the cleanup crew home early.
