Single infrared sauna session for blood sugar control in adults with overweight

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial uses a randomized crossover design in which each participant completes two lab visits: one with two 20-minute infrared sauna exposures (175°F / 79°C, separated by a 5-minute break) and one with quiet seated rest, separated by at least 72 hours. Participants wear a continuous glucose monitor (CGM) and have baseline and repeated measurements of blood pressure, heart rate, and oral temperature; standardized meals are provided and activity is limited. After each condition participants consume identical meals at home and glucose responses over the day are compared between conditions. A familiarization sauna session is completed before the experimental visits to ensure participant tolerance.
