Official title
Targeting Hypertension and Insulin Resistance With Heat Therapy
Overview
This is a clinical trial to determine if 30 sessions of far infrared sauna bathing can improve cardiovascular and metabolic function in adults with obesity.
Detailed description
Obesity can increase the risk for cardiovascular and metabolic diseases. Lifestyle interventions are needed to reduce this risk. Far infrared saunas are one form of heat therapy that may help reduce these risks, however, there is limited research within a population with obesity. It is hypothesized that repeated far infrared sauna bathing will improve cardiovascular and metabolic function in adults with obesity.
Interventions
- Other Heat therapy
30 sessions of far infrared sauna bathing (45-60C) for up to 45 min
Primary outcome measures
- Blood pressure change [Time frame: 10 weeks]
- Blood glucose [Time frame: 10 weeks]
Secondary outcome measures (2)
- Arterial stiffness reduction [Time frame: 10 weeks]
