Can cold exposure melt away liver fat?
NCT ID NCT07821749
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers test whether repeated cold exposure using a water-perfused cooling suit can reduce liver fat and improve liver health in adults with metabolic dysfunction-associated steatohepatitis (MASH). Eleven participants wear the suit for about two hours daily over three months. The study measures changes in liver fat by MRI, liver enzymes, cholesterol, and body weight, and tracks safety and tolerability.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a water-perfused cooling suit that lowers body temperature through circulating cold water
- What this could lead to
- If cold exposure helps, it could offer a drug-free way to reduce liver fat and ease liver stress in people with MASH.
- What could go wrong
- This is a tiny, single-arm study with no control group, so any changes could be due to chance or other factors. Cold exposure can cause discomfort, and people with heart or circulation problems may not tolerate it.
