Pilot trial detected no short-term symptom differences between stress programs
Symptoms improved across programs in stressed women. A later finding favoring the Wim Hof Method came from an exploratory analysis.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Depression symptoms and perceived stress decreased across the programs, with no detected differences between groups immediately afterward. This does not establish that the programs work equally well or that the changes were caused by their specific techniques. A later finding favoring the Wim Hof Method relied on a post hoc analysis of adherent participants.
The later analysis was exploratory and selected participants by adherence. This abstract-based account cannot assess all analysis details; the sample included only women and was predominantly White or Asian.
What researchers found
Depressive symptoms and perceived stress
After 3 weeks, no detected differences among meditation, the breathing-and-shower programs and interval training.
Why the main comparison matters
Every group received an active program, including the breathing and warm-shower control. Improvement within groups cannot identify a technique's specific effect. The abstract also reports similar cortisol responses to a laboratory stressor.
Interpreting the later finding
Among participants who followed their programs, an exploratory analysis suggested more sustained improvement in depression with the Wim Hof Method. The authors call for replication, so this does not establish a preferred program.
