Your Brain On Nature


SCROLL DOWN

Your Brain On Nature


Science Says : Get Outside!

“The mountains are calling and I must go.”

We’ve probably all heard this famous quote by John Muir and felt it resonate deep in our body and soul. But why do the mountains call to us? And why is it so important that we go when we hear that call?

When you’re stressed out by day-to-day life, I’m sure you’ve experienced how beneficial a simple stroll outside can be. If you’ve tried camping or hiking, you’ve likely felt the rejuvenation in the moment first hand.

It’s not just anecdotal evidence that nature is good for us. Scientists across the globe are now studying the benefits of connecting with nature. Truth is, humans aren’t built for a sedentary lifestyle as it can make our brains and bodies short-circuit.

Let’s get down to facts regarding the benefits of spending time outside:

  • Did you know that spending just 15 minutes in the woods reduces your levels of cortisol (NY Times)?  High levels of cortisol cause all sorts of health problems, from lower immune function to increased weight gain. Elevated cortisol is also a factor in depression, mental illness, and shorter life expectancy. Getting outside in nature is a fantastic way to lower those levels almost instantly.

  • Spending time in nature has also been scientifically proven to foster creativity. A study run in 2012 showed that after a few days out on the trail immersed in nature, backpackers were 50% more creative on word association tests than those who were given the tests without spending time outside. 

  • Scientists believe that nature calms down the prefrontal cortex, which allows your brain to access a network of its many other regions that can lead to flashes of insight. This happens when you’re in a state of “soft fascination” - like appreciating the natural beauty around you when you’re hiking, or sitting on the banks of a body of water and watching the currents flow. It’s no wonder that artists, writers, and other creative types often seek out natural spaces to do their best work.

  • This relaxation of the prefrontal cortex is also similar to the effects of meditation. Have you ever tried meditation but found it hard to stick to your practice? You're not alone, and there's still hope for you too. Just walking outside and spending time amongst trees can be as effective as regular meditation practice (just don’t tell that to my teachers!!).

  • A 2015 study showed the effects which walking in nature has on morbid rumination. I think we’re all familiar with this feeling from time to time– When we ruminate, we overthink or obsess about situations or life events, such as work or relationships. In this study, half the participants were told to take a 90-minute walk through a tree-lined area, while the other half were assigned to walk along a busy highway. A questionnaire given after the walks showed that those who walked through the trees, “were not dwelling on the negative aspects of their lives as much as they had been before the walk.” And the scientists measured blood flow to the prefrontal cortex of the brain, and found that it had gone down in the subjects who walked in nature, suggesting reduced activity and a calmer mind. 

  • Another study showed that “nature can have humanizing effects, fostering greater authenticity and connectedness.” Students who were exposed to nature, through outdoor images or plants in their environment, reported valuing personal relationships and helping their community more than money or other superficial goals, whereas those who were not exposed to nature in some way responded more selfishly.

Being together in nature provides some of the most meaningful connections you can have with your friends, family, partner and self. Getting outside will lessen the distractions of day to day life, give you a chance to focus on the people you’re with and provide an opportunity for deep meaningful conversations. Sharing moments of marveling in the beauty of a sunset or the majesty of a mountain builds a special and undeniable bond.

Science is magic. I find the convergence of nature and human existence absolutely incredible and I love to help people get a glimpse of the often unexplainable joys of life. Our world is changing, and humans are slowly migrating indoors. It's indisputable that this migration is changing the ways we interact with our planet. Getting outside more often can be a key-stone habit that could improve our social lives, inner peace and perspective of the world in unimaginable ways.

I promise you that just one similar experience will leave you a changed person, thus a better person, thus a healthy happy human.
