This Simple Movement Could Be Secretly Cleaning Your Brain
Key Points:
- A new study published in Nature Neuroscience reveals that simple abdominal muscle contractions can cause subtle brain movements that help cerebrospinal fluid circulate, potentially clearing waste that impairs brain function.
- Researchers at Penn State used advanced imaging on mice and computer simulations to show that abdominal tightening pushes blood into the spinal cord, creating pressure that shifts the brain slightly within the skull and drives fluid flow.
- The study likens the brain to a sponge being squeezed to promote fluid movement, suggesting that everyday physical activities involving abdominal contractions may support brain health by aiding waste removal.
- While further research is needed to confirm these effects in humans, the findings provide a physiological explanation for why physical activity benefits brain health and may help reduce risks of neurodegenerative diseases.
- The research was conducted by an interdisciplinary team at Penn State with support from the NIH, Pennsylvania Department of Health, and American Heart Association.
