The speed at which a new habit forms depends directly on its level of importance and urgency: the brain can reorganize its circuits very rapidly if the situation is perceived as critical.

Reference works, such as an observational study by Phillippa Lally (2009) and a systematic review by Ben Singh (2025), indicate that it takes an average of two months to automate a new routine in a standard context. However, neurobiological research confirms that urgency triggers the release of stimulating molecules like epinephrine, which act as accelerators for brain plasticity. This phenomenon sometimes allows for one-trial learning, which is essential for survival in the face of immediate danger. Thus, the brain does indeed possess the biological capacity to rewire itself rapidly under the influence of absolute necessity. Nevertheless, applying this concept of acute stress to attempt to adopt ordinary daily wellness routines more quickly remains an exaggeration. For the latter, regular and progressive repetition remains the most reliable method validated by science.
