Hot and cold therapy tested as depression treatment
NCT ID NCT06263738
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a single session of whole-body heat therapy (using an infrared sauna) with or without a cold water plunge can reduce depression symptoms. Researchers will enroll 162 adults with depressive symptoms and track their mood changes over two weeks. The goal is to see if these temperature-based procedures offer a simple, non-drug option for mood improvement.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Whole Body Hyperthermia (infrared sauna) and Cold Water Plunge
- What this could lead to
- If it works, this could point toward a simple, drug-free way to reduce depression symptoms using heat and cold exposure.
- What could go wrong
- This is a small, early-stage trial with only a single treatment session and short follow-up. Results may not last or apply to everyone, and there are risks like discomfort or adverse reactions to extreme temperatures.
