Our brains shape almost everything that makes us who we are.
They allow us to think, remember, communicate, move, create, make decisions and connect with the people around us. Yet brain health is something many of us don’t really think about until something begins to change.
World Brain Day, held every year on 22 July, aims to change that.
The theme for 2026 is Brain Health: Access for All, highlighting not only the enormous global impact of neurological conditions, but the importance of ensuring that everyone has access to information, prevention, early diagnosis and appropriate care.
More than 3.4 billion people worldwide are living with neurological conditions, which are now the leading cause of disability globally.
But brain health isn’t simply about treating neurological disease.
There are things we can do throughout our lives to create a healthier environment in which our brains can function and age.
What Do We Mean by Brain Health?
A healthy brain isn’t simply one without disease.
Brain health encompasses our ability to:
- Think and concentrate
- Learn and remember
- Communicate
- Regulate emotions
- Move and coordinate our bodies
- Make decisions
- Maintain independence as we age
And although genetics influence our risk of developing certain neurological conditions, our brains don’t exist in isolation.
Nutrition, cardiovascular health, metabolic health, sleep, physical activity, stress, social connection and even the health of our gut can all influence how well our brains function.
This means that supporting brain health requires a whole-body approach.
1. Nourish Your Brain
The brain is one of the most metabolically active organs in the body and requires a continuous supply of energy and nutrients.
Dietary patterns rich in vegetables, fruit, whole grains, legumes, nuts, seeds, healthy fats and good-quality protein provide nutrients involved in maintaining healthy brain cells and protecting against oxidative stress.
Two dietary patterns receiving particular attention in brain-health research are the Mediterranean diet and the MIND diet.
Both emphasise predominantly whole, plant-rich foods alongside healthy fats and have been associated with better cognitive health as we age.
But there isn’t necessarily one perfect diet for everyone.
Individual nutritional needs, metabolic health, medical conditions and the gut microbiome can all influence how we respond to food—which is why a personalised approach can be particularly valuable.
2. Don’t Forget the Gut-Brain Connection
One of the most fascinating developments in neuroscience and nutritional research has been our growing understanding of the gut-brain axis.
The gut and brain communicate continuously through several pathways involving the nervous system, immune system, hormones and compounds produced by our gut microbes.
These microbial compounds—known as gut metabolites—can influence inflammation, immune activity and signalling throughout the body.
This means that supporting a diverse and resilient gut microbiome may also be one part of supporting brain health.
A varied diet containing plenty of different plant foods and sources of dietary fibre helps provide fuel for beneficial gut microbes.
Once again, what we eat isn’t simply feeding us.
It’s feeding an entire microbial ecosystem that communicates with the rest of our body.
3. Keep Moving
Physical activity is one of the most consistently recommended lifestyle habits for supporting brain health.
Movement helps maintain:
- Healthy circulation to the brain
- Cardiovascular health
- Blood glucose regulation
- Metabolic health
- Mood and emotional wellbeing
Exercise is also associated with processes involved in neuroplasticity—the brain’s remarkable ability to adapt and form new connections.
And it doesn’t have to mean spending hours in a gym.
Walking, gardening, swimming, dancing, cycling or any activity that gets your body moving regularly can contribute.
The best form of exercise is often the one you can realistically continue doing.
4. Make Sleep a Priority
Sleep is not simply a period when the brain switches off.
Quite the opposite.
During sleep, the brain carries out essential processes associated with:
- Memory consolidation
- Learning
- Emotional regulation
- Cellular repair
- Metabolic housekeeping
Poor or insufficient sleep can affect concentration and memory in the short term, while long-term sleep disruption has also become an important area of research in relation to cognitive health.
Creating a consistent sleep routine and addressing persistent sleep problems should therefore be considered part of looking after the brain—not an optional luxury.
5. Keep Challenging Your Brain
Our brains remain capable of changing throughout life.
This ability is known as neuroplasticity.
Learning and mentally stimulating activities encourage the brain to continue forming and strengthening neural connections.
That might mean:
📚 Reading
🎨 Creating art
🎵 Learning an instrument
🌱 Gardening
🧩 Puzzles and games
🗣 Learning a language
🍳 Trying unfamiliar recipes
💻 Developing a completely new skill
It doesn’t necessarily matter what you choose.
Curiosity itself is good exercise for the brain.
6. Stay Connected
Human beings are social creatures, and meaningful relationships appear to matter to our brains as much as they do to our emotional wellbeing.
Social interaction requires the brain to perform an extraordinary range of tasks simultaneously—from language and memory to interpreting facial expressions, emotions and social cues.
Maintaining friendships, family connections and community involvement can therefore provide valuable cognitive stimulation.
Loneliness and social isolation, meanwhile, are increasingly recognised as important factors in long-term physical and mental health.
A conversation over a cup of tea may be doing more for your brain than you realise.
7. Look After Your Heart to Look After Your Brain
Brain health and cardiovascular health are closely connected.
The brain depends upon a healthy blood supply to deliver oxygen and nutrients.
Factors that affect blood vessels and metabolic health—including high blood pressure, diabetes, smoking and cardiovascular disease—can therefore also affect the brain.
Supporting healthy:
- Blood pressure
- Blood glucose
- Cholesterol
- Body composition
- Cardiovascular fitness
isn’t simply about protecting your heart.
It’s part of protecting your brain too.
What About Medicinal Mushrooms?
Another fascinating area of emerging research is the potential role of certain medicinal mushrooms in supporting cognitive and neurological health.
Lion’s Mane (Hericium erinaceus) has attracted particular scientific interest.
It contains compounds called hericenones and erinacines, which are being investigated for their potential influence on Nerve Growth Factor (NGF).
NGF is a protein involved in the growth, maintenance and survival of certain nerve cells.
Other medicinal mushrooms contain compounds with antioxidant, anti-inflammatory and immunomodulatory properties that are also being explored in relation to healthy ageing.
This is an exciting field, but it’s important to keep the research in perspective.
Medicinal mushrooms aren’t a magic solution or a replacement for medical treatment.
Instead, they may eventually prove to be one interesting part of a much broader approach to supporting brain health.

Brain Health Should Be Accessible to Everyone
The message behind World Brain Day 2026 – Brain Health: Access for All extends beyond individual lifestyle choices.
People everywhere should have access to:
- Reliable information about protecting brain health
- Preventative healthcare
- Early diagnosis
- Appropriate treatment
- Rehabilitation and ongoing support
Recognising changes early is particularly important.
Persistent changes in memory, speech, movement, balance, behaviour or cognition shouldn’t simply be dismissed as “getting older.” Seeking appropriate medical advice allows symptoms to be properly assessed.
Small Steps, Taken Consistently
There is no single food, supplement or habit that guarantees lifelong brain health.
Our brains are influenced by a complex combination of genetics, environment, nutrition, physical health and lifestyle.
But that doesn’t mean we’re powerless.
A nourishing meal.
A daily walk.
Seven or eight hours of good-quality sleep.
Learning something unfamiliar.
Looking after your gut.
Managing cardiovascular and metabolic health.
Spending time with people who matter to you.
Individually, these actions can seem very small.
Together—and repeated over years—they help create the foundations upon which healthier brains can age.
Perhaps that’s the most useful message to take from World Brain Day:
Looking after your brain isn’t something that needs to begin when you’re older or when something goes wrong.
Brain health is a lifelong investment—and it’s never too early or too late to begin.
