Post-exercise Hot Water Immersion to Improve Overnight Blood Pressure
Sponsor: Providence College
Summary
The goal of this clinical trial is to test whether putting a participant's legs in a hot bath after exercise improves blood pressure in people with higher blood pressure. . The main questions it aims to answer are: * Whether exercise alone, hot water leg bath alone, or both treatments together cause blood pressure to be lower during sleep. * If there are any changes in heart rhythm or blood vessel health after exercise, hot water leg bath, or the two treatments together that relate to changes in blood pressure. Participants will complete four different trials: * 30 minutes of walking with a 45-minute lukewarm leg bath after * 30 minutes of walking with a 45-minute hot leg bath after * 45 minutes of a hot leg bath with no exercise * A day with no exercise or leg bath Researchers will look at heart rhythm, blood vessels, and blood pressure after each of these trials to see if there are differences, and if exercise and heat together can improve heart health more than exercise or heat alone.
