Breathing is traditionally thought of as an automatic process driven by the brainstem—the part of the brain controlling such life-sustaining functions as heartbeat and sleeping patterns.

Simply put, changes in breathing—for example, breathing at different paces or paying careful attention to the breaths—were shown to engage different parts of the brain.
Neuroscientists have identified how exactly a deep breath changes your mind — Quartzy
