Study Details

Brief summary:

The goal of this clinical trial is to examine the effect of a single 40-minute sauna session on glucose control in individuals at risk for metabolic impairments.

Research Questions:

  • Can a single sauna session completed before a meal reduce the post-meal blood glucose response?
  • Can a single sauna session improve 24-hour glucose control?

Study Design:

Participants will complete two lab visits: one involving a sauna session and one placebo visit (resting condition). Researchers will compare the effects on glucose control using a continuous glucose monitor (CGM).

What Participants Will Do:

Attend a sauna familiarization session Have a CGM sensor placed on the upper arm Visit the lab twice (once for sauna, once for placebo) Consume three standardized meals at home after each session
