skin cooling during heat stress helps maintain blood flow to the brain and supports circulatory stability
Skin cooling during heat stress maintains cerebral blood flow velocity and orthostatic tolerance, demonstrating that extracranial heat dissipation directly influences cerebral perfusion.
What this means for you
When your body manages heat effectively at the skin's surface, blood flow to the brain stays more stable — even when you shift positions. This kind of circulatory resilience is what helps you feel clear-headed and steady rather than lightheaded or foggy after a warming session.
