Passive Heat Therapy for People With COPD
The Acute and Chronic Benefits of Passive Heat Therapy for People With COPD
University of British Columbia
32 participants

INTERVENTIONAL
Conditions
Summary
People with Chronic Obstructive Pulmonary Disease (COPD) often develop high blood pressure and heart disease due to their sedentary lifestyle and difficulty exercising. The investigators will test if heating can mimic the health benefits of exercise by monitoring the increase in leg blood-flow using ultrasound during a 45-minute hot-water footbath. The patients will then undergo 6-weeks of hot-water footbaths to examine whether the changes to blood-flow lead to improvements in blood pressure and other indicators of heart disease risk.
