heat exposure causes measurable fluid redistribution in the body
Plasma volume decreased significantly after each sauna bath (approximately −8% to −9.5% in the 30-min group), indicating substantial fluid redistribution during heat exposure.
What this means for you
When your body heats up, fluid shifts between compartments — a normal physiological response that signals your cardiovascular system is working hard to manage temperature. This kind of circulatory challenge, similar to mild exercise, is part of how regular heat sessions may support cardiovascular conditioning and fluid balance over time.
