breathing high-concentration oxygen temporarily reduces cerebral blood flow via vasoconstriction
Hyperoxia (prolonged >15–30 minutes) leads to increased peripheral vascular resistance and general vasoconstriction of most organs, including decreases in cerebral blood flow.
What this means for you
Your brain's blood vessels naturally constrict when exposed to elevated oxygen levels — a protective response that researchers continue to study. Understanding how oxygen concentration affects circulation helps explain why session duration and oxygen levels are carefully considered in wellness protocols designed to support balance rather than excess.
