What Is Neuroplasticity? How Your Brain Changes Throughout Life (and How to Support It Naturally)

How can you support long term brain health and potentially change your life?

For many years, scientists believed that once you reached adulthood, your brain was fixed and no longer capable of significant change. Today, neuroscience tells us a very different story. Throughout your life, your brain has the ability to adapt, strengthen existing neural pathways, and create new connections based on your experiences, habits, and environment.

This incredible ability is known as neuroplasticity.

What Is Neuroplasticity?

Neuroplasticity is the brain's ability to change and adapt throughout life by modifying its structure, function, and neural pathways.

Every time you learn something new, practice a skill, or repeat a thought or behaviour, your brain is constantly reorganizing itself. The more a neural pathway is used, the stronger and more efficient it becomes. Pathways that aren't used as often can gradually weaken over time.

How does it work?

Learning and Memory

Repeated practice strengthens specific neural pathways, making skills and knowledge easier to learn, remember, and perform over time.

Adaptation

Your brain constantly adjusts when faced with new experiences or challenges, whether you're learning a new language, playing a musical instrument, or developing a healthier habit.

Recovery After Injury

Neuroplasticity also plays an important role in rehabilitation. After certain brain injuries, healthy areas of the brain can help compensate for damaged regions by forming new neural connections, supporting recovery over time.

So how can we encourage neuroplasticity in a positive direction and improve our daily lives?

Scientists have been studying this question for years, and research suggests there are several key habits that help support a healthy, adaptable brain.

What Influences Neuroplasticity?

According to research published through the National Library of Medicine, five essential pillars for a healthy brain are newness, challenge, exercise, diet, and love (social connection).

1. Newness

New experiences give your brain unfamiliar information to process, stimulating learning and encouraging the formation of new neural connections.

Examples include:

• Learning a new language or musical instrument
• Trying a new recipe, hobby, or sport
• Meeting people with different perspectives

2. Challenge

Challenge provides the brain with the "training load" needed for growth. If an activity is too easy, there is little reason for your brain to adapt. If it is too difficult, frustration can interfere with learning.

• A good challenge should be:
• Slightly beyond your current ability
• Specific and measurable
• Practiced consistently
• Paired with feedback and correction

3. Exercise

Physical activity is one of the most powerful ways to support brain health.

Exercise improves blood flow to the brain, supports learning and memory, enhances mood, promotes better sleep, and has been associated with a lower risk of cognitive decline.

Current recommendations suggest aiming for at least 150 minutes of moderate aerobic activity each week, along with regular strength training.

Great forms of exercise include:

• Brisk walking, cycling, or swimming
• Strength training
• Yoga or Pilates
• Dancing
• Recreational sports

4. Diet

Your brain requires a steady supply of nutrients to function at its best.

Research consistently shows that one of the healthiest eating patterns for long term brain health is the Mediterranean diet, which focuses on:

• Vegetables
• Fruit
• Whole grains
• Beans and legumes
• Nuts and seeds
• Fish
• Healthy unsaturated fats, such as olive oil while limiting highly processed foods, excess sugar, and excessive sodium.

5. Love

Strong social relationships are good for more than just emotional well-being.

Research has shown that meaningful social interaction supports healthy brain function, while studies in animals have demonstrated that nurturing, enriched environments can positively influence brain development.

Whether it's spending time with family, close friends, or your community, connection is so important as apart of lifelong brain health.

Habits That Can Support Neuroplasticity

✓ Exercise regularly

✓ Prioritize quality sleep

✓ Learn something difficult

✓ Read every day

✓ Practice mindfulness

✓ Strength train

✓ Eat brain-supportive foods

✓ Spend time outdoors

✓ Challenge yourself

✓ Maintain meaningful social relationships

Supplements That May Support Brain Health

While supplements cannot directly "increase neuroplasticity," certain supplements have been studied for their role in supporting healthy brain function.

These include:

• Omega-3 fatty acids (EPA and DHA)
• Vitamin B6, B9 (folate), and B12
• Phosphatidylserine
• L-theanine
• Curcumin
• Creatine
• Lion's Mane mushroom
• Magnesium
• Bacopa monnieri

Journaling and Neuroplasticity

Journaling may help support habits associated with neuroplasticity by encouraging reflection, emotional regulation, learning, and cognitive flexibility.

Rather than simply writing about your day, reflective journaling can help reinforce healthier ways of thinking and create greater awareness of your thoughts, emotions, and behaviours over time.

Practical Ways to Journal for Neuroplasticity

To get the most from journaling, focus on consistent, meaningful reflection rather than simply venting.

Expressive Writing

Spend 15 to 20 minutes writing for 3 to 5 consecutive days with intention. 

Write continuously about:

• What happened in your day/recently
• How you felt
• What an experience meant to you
• What you learned from an experience
• Putting emotions into words can help improve emotional awareness and self understanding.

Name Your Emotions and Reframe Them

Start by identifying exactly what you're feeling.

For example:

• "I feel anxious."
• "I feel frustrated."
• "I feel overwhelmed."

Then ask yourself:

• What is one small step I can take today?
• What could this experience be teaching me?
• Is there another way to look at this situation?

Gratitude

Write down three positive things that happened during your day and why you think they happened.

You can also practice reframing by reminding yourself:

"This positive experience happened because I worked hard for it."

or

"I deserve good things in my life."

Turn Worry Into a Plan

Instead of repeatedly thinking about a problem, turn it into an action plan.

For example:

If this happens...

Then I will...

This simple exercise encourages problem solving instead of overthinking and helps you focus on what it is that is within your control.

Tips to Help You Stay Consistent

Spend just 10 to 15 minutes each day.

Consistency matters more than writing for long periods.

Write by hand whenever possible.

Journal at the same time and in the same place each day.

Don't filter yourself. Be honest and let your thoughts flow naturally.

Ending on a Positive Note

Neuroplasticity reminds us that our brains are constantly changing throughout our lives.

The habits we practice, the thoughts we repeat, the challenges we embrace, and the people we surround ourselves with all influence how our brains adapt over time.

While change doesn't happen overnight, small actions repeated consistently can have a meaningful impact. By supporting your brain through movement, nutritious food, quality sleep, lifelong learning, meaningful relationships, and self reflection, you're giving it the opportunity to continue growing for years to come.

Your brain is always adapting. The question is: what habits are you strengthening today?
