Abstract

Passive heat exposure may be a therapeutic strategy to reduce blood pressure and improve cardiovascular health. Evidence within hypertensive populations indicates acute passive hot water immersion (HWI) causes hypotension that persists over 24 hours. It is currently unknown whether a 24-hour post-heat-exposure hypotensive effect exists in young, healthy individuals. This study aimed to determine the influence of HWI on blood pressure responses within the first hour and the following 24 hours after a single session of HWI
