The Brain-Boosting Power of Novelty: Why New Experiences Are Essential for Lifelong Cognitive Health – Jayney Goddard, MSc, PG Dip Ed, FCMA, FRSM, Founder and President, The Complementary Medical Association

This morning, I got caught in a long traffic jam as I was coming back from the gym. (It’s why the CMA Newsletter is late today!) I was diverted along a country lane that I’d never been down before. I found myself in stationary traffic, looking around at the hedgerows, listening to the birds, and generally enjoying this unexpected break on a sunny spring morning. Instead of feeling frustrated at the delay, something stirred a memory from the recesses of my mind, a recollection of how the human brain really loves novelty. I’ve written on this before, and it prompted me to think about how we can support the people we look after by introducing novelty into our practices and, of course, for those of us who teach, into our courses.

I don’t know if you’ve felt this, but for me, there is a particular feeling that comes, for example, with going on holiday, perhaps stepping off a train in a city you have never visited before. The senses sharpen. Time seems to slow. Details that would normally pass unnoticed — the smell of bread from a side street, the colour of the light on a building, the unfamiliar rhythm of a different language — all register with unusual clarity. That feeling is not simply a pleasant by-product of being on holiday. It is the signature of a brain doing something it is exceptionally good at, and something it has evolved over millions of years to find rewarding: processing novelty.

For complementary and integrative health practitioners and teachers, the science of novelty has profound implications. It connects the dots between mental wellbeing, memory, mood, learning and the long-term resilience of the ageing brain — and offers practical, low-cost interventions that can be woven into daily life. In this article, we look at what neuroscience now tells us about novelty and the brain, why it matters at every life stage, and how to apply the insights with confidence.

What is novelty, and why does the brain love it so much?

In neuroscientific terms, novelty refers to any stimulus, environment, idea or experience that is genuinely new to the brain. The brain treats novelty as biologically significant — partly because something new might represent danger, but more often because something new might represent opportunity, learning or reward.

The brain region that lies at the heart of this response is the substantia nigra/ventral tegmental area (SN/VTA), a small structure deep within the midbrain. The SN/VTA is the principal source of dopamine in the brain — the neurotransmitter most strongly associated with motivation, reward and learning. Functional MRI studies have shown that the SN/VTA lights up specifically in response to novelty, rather than to other forms of stimulus salience such as rareness or emotional content. In other words, the brain reserves a particular form of activation for things that are simply new.

This SN/VTA system is functionally connected to two other key regions: the hippocampus, which is central to memory formation, and the amygdala, which processes emotional significance. When the SN/VTA fires in response to novelty, it floods these regions with dopamine, creating the neurochemical conditions in which the brain learns most effectively.

Novelty and memory: the UCL discovery that changed how we think about learning

A landmark study led by Dr Emrah Düzel at the UCL Institute of Cognitive Neuroscience — published in the journal Neuron — provided some of the clearest evidence to date that novelty actively enhances memory in humans. Participants were shown a mixture of completely novel images, slightly familiar images and very familiar images while their brains were scanned. They were then tested on what they could recall, both after a 20-minute delay and again the following day.

The results were striking. When new information was mixed with familiar information during a learning session, participants’ memory of the slightly familiar material was boosted by around 19 per cent, compared with learning that material in isolation. Novelty did not just help the brain remember the new things — it lifted memory performance for everything learned alongside it.

The mechanism is now well understood. Novel experiences activate the SN/VTA, which releases dopamine into the hippocampus. Dopamine in the hippocampus enhances long-term potentiation — the cellular process by which synaptic connections are strengthened to encode new memories. More recent research has confirmed that direct dopaminergic projections from the VTA to the hippocampus can trigger long-term potentiation and contextual learning even in the absence of any reward, suggesting novelty itself acts as a teaching signal that tells the brain this is worth remembering.

The practical takeaway for educators, therapists and clients is meaningful: introducing novel material — a new technique, a new environment, an unexpected element — is not a distraction from learning. It is one of the most powerful enhancers of it.

Novelty, mood and wellbeing: the happiness connection

If you have ever felt that a weekend in a new place left you lighter and more optimistic, there is now solid neuroscience to back up your intuition. A study led by researchers at New York University and the University of Miami, published in Nature Neuroscience, tracked the GPS data and self-reported moods of more than a hundred participants over several months. The findings were elegant: on days when participants explored more — visiting more places, or simply spending time in new locations — they reported feeling happier.

The brain imaging follow-up showed why. In participants for whom the novelty-mood link was strongest, there was greater coupling between activity in the hippocampus (novelty processing) and the striatum (reward processing). Crucially, this was not about huge holidays or expensive adventures. The mood-lifting effect emerged from everyday variety — taking a different route home, choosing a new café, walking in an unfamiliar park.

Other research has linked a positive sense of novelty to improvements in motivation, creative problem-solving, perceived stress and even depressive symptoms. It is important to draw a careful distinction here, however. Healthy novelty is intentional, exploratory and life-affirming. It is quite different from the impulsive, risk-laden “novelty seeking” that can underpin certain addictive or destructive behaviours. The form of novelty that benefits the brain is curious, considered and grounded.

The neuroplasticity link: novelty rewires the brain

One of the most exciting developments in modern neuroscience has been the recognition that the adult brain remains far more plastic — more able to remodel itself — than was once believed. Neuroplasticity is the brain’s capacity to form new connections, strengthen existing ones, and even generate new neurons in certain regions throughout life. And novelty is one of its most reliable triggers.

In animal studies, environmental enrichment — providing animals with varied, novel surroundings — has been shown to increase brain weight, cortical thickness and dendritic complexity. The catch is that these benefits depend on the experience remaining novel. Once an enriched environment becomes routine, the additional brain changes plateau. It is the newness that does the work, not the stimulation in itself.

Human research points in the same direction. A long-term study of middle-aged production workers found that those whose roles included frequent work-task changes — a form of recurrent occupational novelty — showed better processing speed, better working memory and greater grey matter volume in brain regions that typically decline with age. Even when overall job complexity was relatively low, the simple act of regularly encountering new tasks appeared to act as an in vivo protective intervention for the ageing brain.

Novelty, cognitive reserve and healthy ageing

This brings us to one of the most important concepts in modern brain health: cognitive reserve. Cognitive reserve refers to the brain’s accumulated resilience — the buffer it builds up over a lifetime through education, mentally engaging work, social interaction and varied experiences. People with greater cognitive reserve tend to maintain better function for longer, even in the face of age-related changes or neurological disease.

Lifelong learning, new hobbies, travel, meeting new people and taking up unfamiliar challenges all contribute to this reserve. The Harvard Medical School’s brain health team has highlighted these activities as some of the most evidence-based ways to maintain cognitive fitness across the lifespan.

There is also an urgency to this picture. Recent research published in Communications Biology has shown that the spontaneous firing of dopaminergic neurons in the VTA and SN reduces with age, and that this reduction is causally linked to a decline in novelty-seeking behaviour. Worryingly, the same decline in curiosity has been observed to predict the extent of cognitive decline in Alzheimer’s disease. The implication is that consciously nurturing novelty as we age may be one of the most underappreciated forms of self-care available to us — supporting the very neural systems that begin to quieten over time.

How to bring more novelty into daily life

The good news is that the dose of novelty required to benefit the brain is far smaller than people often imagine. You do not need to upend your life or spend a fortune. The brain responds to the quality of newness, not the scale of it. Some practical, evidence-aligned approaches include:

• Vary your routines: take a different route to work; sit in a different chair; eat breakfast in a new place. The brain’s spatial-novelty system responds to even small environmental changes.
• Learn something genuinely new: a language, a musical instrument, a craft, a sport. The greater the gap from anything you have done before, the stronger the neuroplastic effect.
• Travel — even locally: a market town you have never visited, a different museum, a coastal walk in unfamiliar territory. Novelty does not require a passport.
• Meet new people: novel social interactions activate multiple brain networks at once and are associated with stronger cognitive resilience.
• Mix new with familiar when learning: based on the UCL findings, weave fresh material into existing knowledge rather than studying old and new separately. The novelty boost will lift recall of both.
• Engage with the arts in new forms: a genre of music you do not normally listen to; a play; a gallery; a poetry reading. Aesthetic novelty is a particularly rich source of dopaminergic engagement.
• Cook a new dish, taste a new ingredient: even sensory novelty, including new flavours and textures, activates reward circuitry.
• Slow down to actually notice the new: novelty only benefits the brain when it is consciously perceived. Walking through a new place while distracted yields little. Curiosity is the active ingredient.

Implications for complementary medicine practitioners and teachers

For practitioners working in nutrition, energy medicine, psychotherapy, bodywork, coaching and other complementary disciplines, the science of novelty offers a powerful conversational tool. Many clients arrive in our consulting rooms feeling stuck, low in mood, mentally foggy or anxious about ageing. Alongside the foundational pillars of nutrition, sleep, movement and stress regulation, intentional novelty deserves a seat at the table — not as a luxury, but as a clinically meaningful contributor to brain health, mood and cognitive longevity.

Encouraging clients to identify a small, achievable novelty practice each week — and then reflecting on its emotional and energetic effects — can be a remarkably gentle intervention with disproportionate benefits. It is also one that respects autonomy and personal preference, since each person’s territory of novelty looks different.

Similarly, for those of us working with students, introducing novel elements into our courses can be a wonderful way of stimulating not just recall but enjoyment of your courses. Think about ways that you can incorporate novelty into the training that you offer. And remember that, by incorporating novelty such as a different mode of teaching, an interesting prop, or a different location for teaching, this is doing you just as much good!

My final thoughts: a quietly radical idea

The principle is simple, but quietly radical. The brain is not built to coast. It is built to explore. Every time we seek out something genuinely new — an idea, a place, a person, a skill — we are not indulging ourselves; we are nourishing the very neural machinery that underpins memory, mood, learning and resilience. In a culture that often equates wellbeing with predictability and control, the science of novelty invites us to reconsider. A little more wonder, a little more curiosity, a little more willingness to step into the unknown — these are not optional extras. They are, increasingly, looking like one of the most evidence-based forms of brain care available to us.

Reflective practice exercise (Value one hour CMA continuing professional development)

To convert this article into one formally logged hour of CMA CPD, Members are invited to undertake the following reflective practice exercise:

Having read the article in full, take time in your CPD journal to consider the following questions

Which ideas were genuinely new to you, and which built on or confirmed knowledge you already held?

Looking at your recent client work, can you identify presentations — low mood, mental fogginess, creative inertia, a sense of being “stuck” or fatigued — where a deficit of novelty may have been a quiet but meaningful contributing factor?

How might you now introduce the principle of intentional, healthy novelty into your client conversations, intake questions or treatment plans, and what specific suggestions would best suit the kinds of clients you most often work with?

Are there contraindications, sensitivities or boundaries you would want to hold in mind when recommending novelty-based interventions to particular client groups?

And finally, turning the lens inwards: where might novelty be missing in your own life or professional practice, and what one small new experience could you commit to in the coming month — and how will you observe its effects?

Write up your reflections in approximately 250 to 500 words and upload the document to your CMA membership portal CPD log. The complete exercise — reading, reflection and writing up — is valued at one hour of CMA/CPD.
