An interventional study of Heat therapy in Obesity (Disorder), sponsored by University of Oregon. Recruiting at 1 site in United States. Open to participants aged 18 Years to 59 Years. Per ClinicalTrials.gov, last updated 2026-03-04.
Sponsored by University of Oregon · Not applicable, Interventional, and Basic science
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.
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.
11,522 studies on the registry are indexed under Obesity; 2,033 are open to participants now.
This study's planned enrollment of 20 is below the median of 67 across 9,006 interventional studies indexed under Obesity.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Started Mar 2022 (actual). Primary completion is estimated for Jun 2026, 51 months after the start.
Of 3,680 non-industry interventional studies with no phase under Obesity, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's planned 51 months is above that.
Counting every sponsor, half of 3,843 studies reached it within 22 months; a quarter within 10 and three quarters within 42.
