Could “abs” act as a pump to flush waste from the brain? A mouse study confirms a brain-fluid circulation system driven by abdominal contractions, published in a Nature family journal: Innovative Tech

A mouse study suggests abdominal muscle contractions can mechanically drive brain motion while awake.

Researchers found the effect was linked more to abdominal activity than to heartbeat or breathing.

Blood vessel networks between the abdomen and spine may transmit pressure that helps move brain fluid.

The finding reveals a previously unrecognized body-brain link that could matter for waste clearance and brain health.
