Struggling with restless nights? Learn how the brain’s glymphatic waste-clearing system operates and master evidence-based sleep hygiene steps.
During non-REM deep sleep, the spaces between brain cells expand by 60%, allowing cerebrospinal fluid to flush out metabolic waste products including amyloid-beta plaques. Skipping sleep literally deprives your brain of its nightly cleaning cycle.
Optimal Bedroom Temperature: 65°F to 68°F
Your core body temperature must drop by 1 to 2 degrees Fahrenheit to initiate and sustain deep sleep. A cool room coupled with breathable cotton bedding facilitates this drop.
The 10-3-2-1-0 Rule
- 10 Hours Before Bed: No more caffeine.
- 3 Hours Before Bed: Finish large meals and alcohol.
- 2 Hours Before Bed: Halt intense cognitive work.
- 1 Hour Before Bed: Turn off all blue-light screens (tablets, phones, TVs).
- 0 Times: The number of times you hit snooze tomorrow morning!
