Sweat it out: sauna may tame blood sugar spikes
NCT ID NCT07520929
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a single 40-minute infrared sauna session, done before a meal, can lower blood sugar spikes in overweight adults. Fifteen participants at risk for metabolic issues will wear a continuous glucose monitor and compare sauna versus rest. The goal is to see if heat exposure can improve glucose control without medication.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Infrared sauna session
- What this could lead to
- If it works, this could point toward a simple, drug-free way to help manage blood sugar after meals for people at risk of metabolic problems.
- What could go wrong
- This is a very small, early study with only 15 participants, so results may not apply widely. The effect of a single sauna session may be minimal or temporary.
