The neuroscience of habit, and why novelty is overrated
The Lie We’ve Been Sold
We live in a culture that worships novelty. New experiences, fresh starts, constant reinvention. The wellness industry alone has built an empire on the idea that transformation requires something different, a new programme, a new practice, a new product. Scroll any feed for thirty seconds and you’ll find someone telling you to shake things up, mix it up, level up.
But here’s what the neuroscience actually says: your brain doesn’t thrive on novelty. It thrives on repetition. And the most powerful thing you can do for your mental clarity, emotional stability, and long term wellbeing might be the most unglamorous one, doing the same thing, in the same way, at the same time, day after day.
Boring, by most modern standards. And yet, neurologically, it’s one of the most intelligent things you can do.
What Your Brain Is Actually Doing All Day
Before we get into routine, we need to understand something about how your brain manages energy.
The brain accounts for roughly 2% of your body weight, but it consumes approximately 20% of your body’s total energy. It is extraordinarily expensive to run. And because of that, it is constantly looking for ways to become more efficient.
When life is unpredictable, the prefrontal cortex, the part of the brain responsible for decision making and planning, has to work overtime. This leads to mental fatigue, anxiety, and slower responses. The prefrontal cortex is your brain’s most energy hungry region. It handles conscious thought, reasoning, impulse control, and complex decision making. Every time you face an unfamiliar situation, it fires up. Every time you make a deliberate choice, what to eat, how to respond, what to prioritise, it draws on a finite pool of cognitive resources.
And that pool depletes.
The average adult makes approximately 35,000 decisions daily, from the mundane selection of breakfast cereals to consequential professional judgments. Yet this constant choosing exacts a toll, a state of mental depletion that progressively erodes decision making quality.
This is not a character flaw. It is not a lack of willpower. It is biology.
The Basal Ganglia: Your Brain’s Efficiency Engine
Here is where it gets fascinating.
Deep within the brain sits a cluster of structures called the basal ganglia. These structures, already known to control voluntary movements, also play a critical role in how people form habits, both bad and good, and in influencing mood and feelings.
When we first learn something new, it requires active focus and attention from the prefrontal cortex. But as we repeat a task, the basal ganglia takes over, allowing us to perform the action almost automatically. This shift from conscious effort to subconscious behaviour is what makes habits so powerful.
Think about learning to drive. The first time, it was overwhelming, mirrors, clutch, gears, road, other cars, all processed simultaneously by a prefrontal cortex working at full capacity. Now you probably drive and hold a conversation without conscious effort. The routine has been handed over. The basal ganglia have taken charge. Your higher brain has been freed.
MIT research has shown that neurons in this brain region fire at the outset of a learned routine, go quiet while it is carried out, then fire again once the routine ends, a kind of neurological task bracketing that initiates a routine and notifies the brain once it is complete.
In other words, the brain doesn’t just tolerate routine. It actively organises around it. It packages repeated behaviours into efficient neural units, and then protects them. Habits form slowly, but with repeated successful practice, behavioural strategy transitions from reliance on action outcome knowledge to more automatic execution. Habits are resource efficient.
Efficiency. That is what routine gives the brain. Not boredom. Freedom.
Decision Fatigue: The Hidden Cost of Too Much Choice
There is a reason Barack Obama wore the same style of suit almost every day during his presidency. It wasn’t a fashion statement. It was a cognitive strategy.
As president, Obama had countless decisions to make every day, some incredibly important, like how to deal with overseas threats, while others were more mundane, like what to wear. To limit the number of decisions he had to make and ensure he was in top form for the most important ones, he wore the same coloured suits every day. Obama understood decision fatigue and how it can compromise the quality of important choices.
The brain’s basal ganglia are highly involved in habit formation, allowing actions to become automatic and consume minimal cognitive effort. Developing consistent morning routines, what to wear, consistent breakfast choices, daily planning rituals, bypasses the need for conscious decision making and conserves willpower.
Research from Duke University suggests that approximately 45% of daily behaviours follow habitual patterns rather than deliberate choices. By converting decisions into habits, cognitive resources can be redirected to non routine challenges.
This is the hidden intelligence of routine. Every repeated behaviour that becomes automatic is one less demand on your prefrontal cortex. One less withdrawal from a finite account. More capacity left for the things that actually require your full attention, your work, your relationships, your creative life, your presence.
Routine and the Nervous System: More Than Efficiency
Beyond cognitive load, routine does something even more fundamental. It regulates the nervous system.
Routines act as a mental anchor, creating predictability in a world that often feels out of control. Knowing what to expect reduces the fight or flight response and promotes calmness.
The research backs this up clearly. Studies have found that keeping a routine was associated with anxiety scores significantly lower than those who did not maintain one, with benefits observed across both adults and children.
Research published in peer reviewed literature found that repetitive and ritual sequences help the human cognitive behavioural system return to low entropy states and reduce anxiety. By providing well ordered, predictable perceptual patterns, ritualistic behaviour helps minimise internal prediction error, the brain’s experience of uncertainty as threat.
Read that again: the brain experiences unpredictability as threat.
When your mornings are chaotic, when your evenings are formless, when each day is structurally different from the last, your nervous system cannot fully settle. It stays slightly braced. Slightly vigilant. That low level activation, barely perceptible on any given day, is cortisol quietly doing its work, keeping the sympathetic nervous system switched on when it should be winding down.
Routine is not rigidity. It is signal. It tells the nervous system: this is known, this is safe, you can soften now.
Neuroplasticity: How Repetition Literally Reshapes the Brain
Here is the part that I find most compelling, and most relevant to everything Ahloki stands for.
Neuroplasticity is the brain’s ability to reorganise itself, to form new neural connections in response to experience. It is one of the most important discoveries in modern neuroscience, and it carries a profound implication: your brain is not fixed. It is being shaped, continuously, by what you repeat.
Consider the habitual act of morning coffee consumption. Initially, this requires active cortical processing, engaging executive functions within the prefrontal cortex for planning and decision making. With repetition, the basal ganglia, particularly the caudate nucleus and putamen, increasingly automate this sequence. Concurrently, dopaminergic reinforcement strengthens the behaviour, consolidating the action into a habitual routine.
What is true for making coffee is equally true for lighting a candle, taking three conscious breaths, sitting in stillness for five minutes before the day begins. Repeat it consistently enough, and the brain stops treating it as an effortful task. It becomes a cue. A doorway. A signal the nervous system learns to trust.
This is the science behind why small rituals have such outsized effects. Not because they are magical, but because repetition is the language the brain actually learns in.
The Novelty Trap
So why does the culture keep selling us novelty?
Because novelty does produce a neurological response. Novel stimuli excite dopamine neurons and activate brain regions receiving dopaminergic input. Dopamine drives exploratory behaviour in novel environments. That spike feels good. It feels like progress. It mimics the sensation of growth.
But there is a crucial distinction between the dopamine of novelty and the dopamine of mastery. Novelty produces a short burst, the excitement of the new. Mastery, built through repetition, produces something more sustained: the quiet satisfaction of competence, the calm of a practised mind, the confidence that comes not from excitement but from recognition.
The problem with chasing novelty is that it keeps the prefrontal cortex perpetually engaged, the nervous system perpetually stimulated, and the basal ganglia perpetually underused. You never go deep. You never automate. You never free your higher brain, because you keep starting again.
The wellness industry is, ironically, one of the biggest offenders. New routines, new rituals, new programmes, each one abandoned before it has had time to actually embed. Before the brain has had sufficient repetition to hand the behaviour over. Before calm has had the chance to become familiar.
Forty days is often cited as the minimum for habit formation. Some research suggests it takes considerably longer, closer to 66 days on average for a behaviour to become automatic. Either way, far longer than the next trend cycle.
What This Actually Looks Like in Practice
None of this means life should be monotonous. Novelty has its place, in creativity, in learning, in joy. The point is not to eliminate newness. The point is to stop mistaking stimulation for growth.
The most grounded, mentally clear, emotionally resilient people tend to share one thing: anchored daily rhythms. Not rigid timetables. Rhythms. Repeated sensory cues that tell the nervous system where it is in the day.
A morning that begins the same way, a specific light, a specific scent, a specific stillness, teaches the body that the day is beginning from a place of calm rather than chaos.
An evening that closes the same way, a wind down ritual, a boundary between the day’s demands and the body’s need for rest, teaches the nervous system that it is safe to release.
These are neurological investments. Each repetition deepens the pathway. Each familiar cue lowers the activation threshold a little further. Over weeks and months, the body begins to meet these moments not with effort but with recognition.
That recognition is what calm actually feels like, not the absence of difficulty, but the presence of something steady underneath it.
A Note on Sensory Ritual
This is where scent becomes more than atmosphere.
Of all the sensory cues we can build a routine around, smell is neurologically the most powerful. Unlike sight or sound, scent bypasses the brain’s rational relay system entirely and travels directly to the limbic system, the region responsible for emotion, memory, and autonomic regulation. It is the only sense with this direct pathway.
Which means that when a particular fragrance becomes associated, through repetition, with a particular state of mind, the scent itself becomes the cue. Not just a pleasant experience. A neurological shortcut.
Light the same candle each morning. Diffuse the same botanical scent before you sit down to work. Let the smoke from palo santo mark the close of the day. Do this consistently, in the same way, in the same space, and the brain will begin to respond before you’ve even settled into the moment.
That is not indulgence. That is the nervous system doing exactly what it is designed to do, learning from what you repeat, and becoming more efficient at returning to the states you practise most.
The Takeaway
Boring routines are not a compromise. They are not what you do when life gets less exciting. They are one of the most sophisticated things you can do for your brain.
They free cognitive resources. They regulate the nervous system. They reduce cortisol, lower anxiety, and create the neurological conditions for clarity, creativity, and calm, not occasionally, but as a baseline.
The brain does not need more novelty. It needs more repetition with intention.
Build the rhythm. Trust the repetition. Let the familiar become the foundation, and watch what becomes possible from there.
At Ahloki, the ritual collection was built around exactly this principle: that small, consistent, sensory practices can gradually reshape the way the nervous system inhabits the day. Explore The Ritual Space.
