Hypnosis and behavioural approaches offer promising avenues for changing certain habits, anxiety or sleep. Souffle turns this knowledge into short practices while distinguishing published findings from its own design choices.
A scientific publication is not a set of instructions ready to be built into an application. Souffle uses it as a starting point, then creates a coherent experience: decisions made in advance, guided sessions, regular practice and tools available during difficult moments.
Prepare a response
Implementation intentions link a specific situation to an action chosen in advance. A meta-analysis of 94 studies reports a favourable effect on goal attainment, with effectiveness depending in particular on the quality of the goal and the context.
In Souffle You prepare a simple response before a difficult situation occurs, so that you do not have to decide everything while under pressure.
Keep in mind A plan makes action easier; it does not guarantee it.
Find a point of support
A meta-analysis bringing together 15 studies and 17 trials reports favourable results for anxiety. The observed effect was greater when hypnosis complemented another psychological intervention rather than when it was used alone.
In Souffle Short sessions help you slow down, direct your attention and gain perspective when tension rises.
Keep in mind These findings concern hypnosis in different contexts, not Souffle specifically or the self-directed treatment of an anxiety disorder.
Let night come
A systematic review of 24 publications concludes that hypnosis shows promising potential for sleep. More than half of the included studies reported a benefit, but samples, protocols and methodological quality remained variable.
In Souffle The program offers a transition ritual, relaxation and a way to reduce the effort around falling asleep.
Keep in mind For chronic insomnia, cognitive behavioural therapy for insomnia remains the first-line approach.
Prepare to quit
The conclusions remain mixed. The 2019 Cochrane review found no clear benefit of hypnotherapy over other approaches. A review published in 2025 identified more positive studies while calling for more rigorous trials and better objective criteria.
In Souffle Sessions support preparation, quit day and cravings, using responses chosen in a calm moment.
Keep in mind Behavioural support and, when indicated, pharmacological support remain the best-established options.
Cochrane, 2019 · Ekanayake and Elkins, 2025 · Hartmann-Boyce et al., 2021
The broadest bodies of work invite us to take hypnosis seriously without extending conclusions beyond the areas actually studied.
Rosendahl et al. brought together 49 meta-analyses covering 261 primary studies in 2024. The strongest findings concerned pain and certain medical procedures. Nine meta-analyses reached a high methodological standard.
This overview confirms that hypnosis has a genuine research base, but one that varies across uses.
Scheffrahn et al. reviewed 168 hypnosis applications in 2025. Only four stated that they had been included in a clinical efficacy trial.
There is therefore a substantial gap between general hypnosis research and the evaluation of applications that offer it.
The duration of the programs, the 90-second format, session order, texts, animations and soundscape are choices specific to Souffle. They aim to make practice simple and coherent; they are not scientific prescriptions.
