During the day toxic junk builds up in your brain.
All that gunk needs to be flushed out, especially a protein called amyloid beta, or your risk of Alzheimer’s increases. The glymphatic system is the apparatus that flushes all that funk.
The main waste product the glymphatic system is rinsing down the drain is a protein that accumulates in the brain of Alzheimer’s patients. That brain toilet called the glymphatic system is 60 percent more productive when we are asleep.
Studies show that people with a genetic pre-disposition to for Alzheimer’s were able to significantly reduce or delay their risk of getting the disease by simply sleeping better.
Bonus: it appears the glymphatic system works better when you sleep on your side.
