It's not suitable for those with severe hypertension, cardiopulmonary disease, kidney disease, diabetes, substance abuse history (except tobacco), current smokers, or those on hormone replacement therapy.Check my eligibility
What is being tested?
The study tests if lower leg heat therapy at home can help manage high blood pressure in older women when combined with a diuretic drug. Participants will either use warm water immersion up to the knee or a neutral temperature control while taking medication over eight weeks.See study design
What are the potential side effects?
Potential side effects may include discomfort from the heat treatment such as mild skin irritation or burns if not carefully monitored. The diuretic used may cause increased urination, dehydration risks, dizziness or electrolyte imbalances.
