Habits play a crucial role in our daily lives. As outlined in the book ‘Emotional Intelligence: Good Habits‘ by Harvard Business Review, approximately 50% of our daily actions stem from habits that we perform automatically. These routines often operate below our conscious awareness, driving our behavior without us realizing it.
The same mechanisms that help us develop positive habits can make it seem nearly impossible to break negative ones. It goes beyond mere willpower; it involves understanding how our brain functions and how habits are deeply entrenched within it.
Why Do We Adopt Bad Habits?
We are all aware that leading a sedentary lifestyle is detrimental to our health, that spending hours scrolling through TikTok can lead to wasted days, and that smoking seriously impacts well-being. Yet, as Judson Brewer—neuroscientist and author of ‘Undo your Anxiety‘—explains in Harvard Business Review, it’s challenging to break free from these negative habits .
Brewer argues that our environment is designed to bombard us with stimuli that reinforce negative habits. The rewards our brain receives for certain behaviors skew our learning systems towards unhealthy patterns, making them increasingly hard to break. “Every time we attempt to disconnect from a distracting task , we reinforce the reward, leading to a state where harmful distractions can become habitual,” he notes.
Despite the complexity, research by Brewer confirms that it is possible to change bad habits for good. Properly understanding the mechanisms that underpin these habits equips us with vital tools for success.
Bad habits arise from our brain’s reliance on an immediate rewards system akin to animal training. This pattern generally consists of a trigger (e.g., feeling hunger), a behavior (eating), and a reward (achieving satiety). “These three components appear every time we smoke a cigarette or indulge in sweets,” Brewer explains.


Detect the Origin of Bad Habits
Bad habits are not easily eradicated; instead, they should be replaced by good habits . A pivotal step in the journey to conquer negative behaviors is identifying the triggers that prompt the actions leading to the desired reward.
“Once you identify your triggers, work on pinpointing the behaviors that surface during these situations. Do you find yourself scrolling through social media instead of working? Do you reach for sweets when faced with challenging tasks? Recognizing these patterns is crucial,” advises Brewer.
Understanding the context in which these triggers activate is essential for overcoming bad habits. For example, if a craving for sweets emerges during stress, it reveals that the habitual sugar rush is sought for comfort. The first step is to learn how to manage stress instead of turning to the sugary reward.

The Key: Break the Reward Chain
Research conducted at the University of Utrecht suggests that self-control alone isn’t sufficient to eliminate a habit. Our brains associate behaviors with their rewards, often overriding rational thought. While smokers are aware that tobacco is harmful, many continue to smoke.
A vital step to breaking a bad habit involves reducing or entirely removing the reward that the brain receives. This requires altering not only the behavior in question but also the context and sensations associated with it. Adjusting these three elements—trigger, behavior, and reward—is fundamental for the brain to stop associating pleasure with the behavior and ultimately abandon it.
Brewer’s studies indicate that an effective strategy for overcoming bad habits is replacing them with healthier behaviors that offer similar rewards. For instance, he helps patients become aware of the negative aspects of smoking by incorporating mindfulness techniques. This training enables patients to recognize that smoking is not only unbeneficial but also unpleasant.
Brewer recommends that when someone attempts to quit smoking, their first exercise should be to pay close attention to the entire smoking experience: the smell of smoke, the surrounding environment, and the sensations involved. The aim is to help individuals discern the true “value of the reward” and evaluate whether it still holds positive attributes.
Research from the University of Bethesda indicates that when a previously valuable reward diminishes in importance, the likelihood of craving it decreases, simplifying the journey to discard that bad habit. This principle can extend to numerous habits that once had a positive connotation but have since lost their appeal.
Brewer stresses the importance of examining what feelings arise before, during, and after engaging in a bad habit critically, rather than falling into a reactive state of guilt afterward. Acknowledging these feelings can greatly assist in making behavioral changes.
“Your behaviors may not shift overnight, but persistence is key. By mastering your mind using these techniques, over time, you can free yourself from unwanted habits and watch cravings dissolve,” concludes Brewer.
Understanding the complexities behind bad habits is the first step toward transformation. By recognizing triggers, altering context, and modifying reward systems, we can pave the way to healthier behaviors, leading to a more fulfilling lifestyle.
