Deep sleep, the slow wave, non-REM variety, is the best sleep for literally cleansing your brain according to a new study from the University of Rochester.  The scientists studied the effects of deep sleep in a mouse model inducing that state with the unique combination of general anesthetics ketamine and xylazine.

The combination of deep slow wave sleep and the low level cardiovascular activity that accompanies it triggers the so-called glymphatic system, the brain’s unique plumbing apparatus that flushes waste from our brain cells.  This essential purging fails to occur during sleep deprivation and is also less likely to occur as we age when it becomes more difficult to achieve deep sleep.   

Other studies suggest that the onset of Alzheimer’s is associated with less deep sleep and this may be due to poor glymphatic system activity.

You can help yourself get deep sleep at any age with the following tips.  Before bedtime: no eating, caffeinated beverages, exercise, blue light exposure.  While you sleep: keep room cool @ 60-68 degF; keep your nose clear with saline mist; keep air humidified.  Always: maintaining a regular wake-sleep schedule.
