The Claim

Deep breathing increases cerebrospinal fluid displacement and net flow at the foramen magnum in both trained and untrained individuals, indicating that acute respiratory depth enhances cerebrospinal fluid dynamics regardless of prior training.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Deep breathing causes greater movement and flow of cerebrospinal fluid at the base of the skull in all people, whether or not they have trained in breathing techniques.

See the scientific wording

Deep breathing increases cerebrospinal fluid displacement and net flow at the foramen magnum in both trained and untrained individuals, indicating that acute respiratory depth enhances CSF dynamics regardless of prior training.

Why this might work

When you take a deep breath, your diaphragm moves down and pushes on blood vessels in your chest, which drains more blood out of the veins in your head. This creates a temporary vacuum inside your skull, pulling spinal fluid upward. At the same time, your heart rhythm slows and speeds up with your breathing, making your arteries pulse more strongly, which also pushes fluid upward at the base of your skull. Together, these two forces move more fluid through the opening where the spine meets the skull.

  1. Study: Human cerebrospinal fluid net flow enhanced by respiration during the awake state

    Taking slow, deep breaths makes more fluid move around the base of the brain, no matter if you’ve practiced breathing exercises before or not.
