abdominal muscles

Researchers at Penn State found that simple body movement can help the brain 'clean itself' through a mechanical process involving abdominal muscles and blood vessels. This process may promote brain health by driving fluid movement and removing harmful waste products. The study used mice models and computer simulations to track fluid movement.

Scientists discovered that tightening abdominal muscles causes the brain to sway slightly, aiding cerebrospinal fluid circulation and potentially removing harmful waste. The motion is linked to pressure changes in blood vessels connected to the brain.
