The Science of Habits

January 06, 2025

Do you find yourself stuck in unhelpful habits that no longer serve your health or wellbeing? Research reveals it takes an average of 66 days to form a new habit. Discover how clinical hypnosis can break unhealthy patterns and support you in building positive, lasting habits aligned with your goals.

The 66-Day Average

A study conducted by Dr. Phillippa Lally and her team at University College London’s Cancer Research UK Health Behaviour Research Centre provides valuable insights into habit formation.

Published in the European Journal of Social Psychology, the research found that, on average, it takes 66 days for a new behaviour to become automatic.

However, this duration varied among participants, ranging from 18 to 254 days, highlighting that habit formation is a highly individual process.

Defining a Habit

Habits are actions performed automatically in response to specific cues, due to their frequent repetition in consistent contexts. This automaticity means that when the cue is encountered, the behaviour occurs without deliberate thought. For example, brushing teeth after breakfast becomes a habitual action triggered by the completion of the meal.

Measuring Habit Strength

The researchers assessed habit strength using a self-report measure of automaticity, adapted from Verplanken and Orbell’s Self-Report Habit Index. Participants rated statements such as “I do this without having to consciously remember,” reflecting the extent to which the behaviour had become automatic.

Key Factors in Building and Breaking Habits

Consistency: Repeating the desired behaviour in the same context is crucial. Consistency helps forge the mental association between the cue and the action.

Contextual Cues: Establishing a clear situational cue, like performing the behaviour after a specific event (e.g., after lunch), aids in habit formation. Variations in the exact timing of the cue (e.g., lunch at different times) do not significantly impact this process.

Perseverance: Forming a habit can take longer than anticipated. It’s essential to persist even if the behaviour doesn’t become automatic immediately.

Missed Opportunities: Occasionally missing a chance to perform the behaviour does not drastically affect habit formation. However, consistent repetition is key; frequent omissions can hinder the process.

Breaking Existing Habits: Disrupting unwanted habits is challenging. Avoiding cues that trigger the undesired behaviour can be an effective strategy. It’s important to note that forming new habits doesn’t erase old ones; instead, the new habits need to become stronger influences on behaviour.

How Clinical Hypnosis Can Help

The process of habit formation, while highly individual, can be supported and expedited through clinical hypnosis. Hypnosis is a powerful therapeutic tool that works with the subconscious mind to break unhelpful or unhealthy habits and replace them with behaviours that align with an individual’s health and wellbeing goals. By addressing underlying patterns and reinforcing positive behaviours, clinical hypnosis provides a supportive framework for lasting change.

If you’re ready to let go of habits that no longer serve you and replace them with ones that promote your health and happiness, clinical hypnosis might be the solution you’ve been looking for.
