DrBeen#49 Norepinephrine, Glymphatic System, and Brain Health
During the wakeful hours, the production of norepinephrine increases. This increase helps with alertness, but also causes vasoconstriction. The outcome is a reduction in the interstitial fluid levels and reduction in the clearance of waste products. During sleep, NE levels reduce, reversing the above mentioned mechanisms, leading to more interstitial fluid movement and more glymphatic clearance of the waste products and better brain health.
