🌲 Why Do we Need Nature?

What neuroscience can teach us about the power of the forest

We spend a large part of our days surrounded by screens, notifications, noise, information and constant stimulation.

Our brain is continuously selecting what deserves our attention, ignoring what does not, switching from one task to another and processing a considerable amount of information.

And then, sometimes, we step into a forest.

The rhythm changes.

The sounds are different. Our eyes settle on the trees, the light filtering through the branches and the movement of the leaves. We walk, we breathe and, little by little, something seems to become calmer.

This feeling is not only poetic.

Neuroscience and environmental psychology have been studying the effects that natural environments may have on our brain, attention and stress levels.

So, why does our brain seem to appreciate nature so much?

🧠 A brain that is constantly stimulated

Our attention is not an unlimited resource.

When we work, use our phones, answer messages or spend time in highly stimulating environments, our brain constantly has to direct and maintain our attention.

Over time, this can become mentally tiring.

Nature offers us a very different environment.

The movement of branches, the sound of the wind, birdsong and changing light can gently capture our attention without necessarily requiring the same amount of conscious effort.

This is one of the ideas behind Attention Restoration Theory, developed by Rachel and Stephen Kaplan: certain natural environments may help restore our capacity for directed attention.

Research continues to explore these mechanisms today.

🌲 Nature and our response to stress

Sometimes, just a few minutes outdoors can make us feel as though our inner rhythm is beginning to change.

Researchers are interested in this feeling too.

Several studies examining exposure to natural environments and forest bathing have found associations with different markers related to stress and the functioning of the autonomic nervous system.

Of course, this does not mean that a walk in the forest can replace medical or psychological treatment when it is needed.

But nature can provide an environment that supports recovery and well-being.

And ultimately, it reminds us of something very simple:

our brain does not function independently from its environment.

🍃 When our attention can finally slow down

In a forest, we can allow our attention to move naturally.

Notice the moss growing on a tree trunk.

Listen to a bird.

Watch the light changing between the leaves.

Smell the damp earth.

This kind of experience engages our senses while temporarily taking us away from the digital and cognitive demands of everyday life.

Some research suggests that exposure to nature may help restore certain aspects of attention and cognitive functioning.

The effects are not identical for everyone, and nature is obviously not a miracle solution.

But it can become a breathing space for our brain.

🌿 What about forest therapy?

Forest therapy, and more broadly the practice of forest bathing, invites us to stop seeing the forest simply as a backdrop.

Instead, we take the time to truly be present within it.

Walk more slowly.

Breathe.

Observe.

Listen.

Touch the bark of a tree.

Notice the scents, temperature, wind and sensations in your body.

There is nothing to achieve.

It is simply an invitation to rediscover a more mindful relationship with our natural environment.

🌲 A little experiment to try

On your next walk in nature, try giving yourself 20 to 30 minutes without any particular goal.

If you can, put your phone away.

Then, one by one, notice:

🌿 something you can see
👂 something you can hear
🍂 something you can smell
🖐️ a texture you can touch

Then simply observe what happens.

Has your breathing changed?

Are your thoughts moving as quickly as they were at the beginning of your walk?

Is your attention becoming more focused on what is around you?

There is no right answer.

The idea is simply to rediscover a sense of presence.
