whole-body heat stress reduces cerebral blood velocity and orthostatic tolerance
Heat stress markedly impairs orthostatic tolerance in humans, associated with reduced cerebral blood velocity, suggesting cardiovascular strain during whole-body heating.
What this means for you
Understanding how heat affects blood flow to the brain helps explain why some people feel lightheaded or dizzy during intense heat exposure. This response is a normal part of how the cardiovascular system adapts under thermal load — and knowing it exists supports smarter, more informed decisions about heat-based wellness sessions.
