Study reveals how abdominal muscle contractions help brain flush waste

From the laboratories of Penn State University comes a finding that reframes the ancient wisdom of movement as medicine: when the body stirs, so too does the brain — not merely in thought, but in literal, measurable motion. Researchers have traced a hydraulic chain from the contracting abdomen, through spinal veins, to the brain itself, where subtle shifts in position appear to drive the circulation of cerebrospinal fluid and the clearance of neural waste.
