Healthy habits are trending: daily wellness, nutrition, fitness, mindfulness are popular on a global scale. What if your sense of smell is the secret weapon in building habits that last?  

Research suggests you can train your brain to associate a specific scent with the positive feelings or rewards of a healthy habit. And we know that scent is uniquely tied to memory, emotion, and pattern‐recognition in the brain.  

But science also tells us that forming new habits takes time — often between 2 to 3 months of consistent repetition, so you might start to see why something as simple as a fragrance ritual could help to strengthen habit formation. “Rituals” give habits meaning, turning them into experiences we look forward to instead of chores we push through.  

Building Healthy Habits 

Habits aren’t an exact science, but there are some consistent habit-forming practices that make intentions stick. Decades of behavioral research show that four elements play a role in whether a new behavior sticks: time, cues, rewards, and repetition. The secret sauce? Engaging your brain. When we create habits and pair them with subtle cues like sound or scent, their impact can be everlasting. 

On average, it takes two to three months for a behavior to feel automatic, though depending on the habit and the person, it can range from just a few weeks to nearly a year. Habits form more easily if tied to something already in your daily rhythm — making coffee, brushing your teeth, or sitting down at your desk. A strong cue acts like a mental “anchor,” telling your brain it’s time for the new behavior to begin. 

Our brains also crave reinforcement — etching a habit into our brain through reward. Whether crossing some items off your to-do list or celebrating with ice cream, without reward even the best intentions may fizzle.  

And of course, consistency is the real habit builder. The more often you perform a behavior in response to the same cue, the faster it becomes automatic. Your alarm goes off, shoes go on, and you go out for a run. You turn on meditation music, sit down, and sink into your breath a little faster. Each day and each repetitive task work to build muscle memory, ultimately ingraining the habit into daily routines without much thought.  

What Makes a Ritual? 

Habits may be the mechanics of change, but rituals are what give them purpose. A ritual takes something ordinary and infuses it with identity, emotion, and meaning. This is the difference between simply making coffee and savoring a morning coffee ritual — one is functional, the other is foundational.  

When a practice reflects who we are and what we value, it stops feeling like a task and starts becoming part of our self-definition. Lighting a candle before journaling or diffusing a calming scent before bed says: this is who I am, someone who chooses presence, care, and intention.  

Smell is uniquely powerful in ritual. “Even a quick whiff of an odor can leave a lasting trace in the brain, one that lingers for several seconds after the smell is gone and can subtly influence how we remember things that happen moments later,” notes behavioral psychologist Joan Tarrida Vidal. 

Across North American ancestry, gathering around the campfire was more than warmth or light: it was an act of connection, storytelling, safety, and shared identity. That same primal bond with scent explains why the smell of smoke, pine, or even baking bread feels grounding and communal. Modern rituals can echo that — whether it’s diffusing cedarwood as you wind down for the night or using citrus to mark the start of your workday. 

Bringing It All Together 

Habits give us structure. Rituals give those habits meaning. And scent can act as the bridge between the two. Because of its unique connection to memory and emotion, fragrance doesn’t just make a space feel pleasant — it encodes the moment. Each time you diffuse the same blend before meditation, your brain pairs that scent with the state of calm, focus, or restoration you’re cultivating. And this works for any habit you’d like to develop. Over time, the fragrance becomes a cue in itself: a shortcut that tells your mind and body, it’s time to shift gears. 

As routines settle back in this season, consider adding fragrance intentionally. Not as a background detail, but as a ritual cue: a sensory signal that carries you into the habits you want to keep and helps them stick.
