Your brain operates a continuous waste-removal system called the glymphatic system, which uses cerebrospinal fluid guided by specialized astrocyte cells to clear harmful proteins and metabolic byproducts. Sleep, cardiovascular health, and exercise enhance this cleanup process, while aging and inflammation impair it—making lifestyle factors critical for long-term brain health. — "The brain’s drain" by Mohsin.ajaz989 is licensed under CC BY-SA 4.0.
