We all know that being in nature makes you feel good, but why?
Deep in the brain is a region called the subgenual prefrontal cortex. Research has linked activity in this region with depression and repetitive, negative thinking called brooding.
Brooding is thinking about the same negative thing over and over. It can sound like:
Why did I do that?
What is wrong with me?
Why can’t I handle this better?
Our students learned about a study by Bratman and colleagues, whereby participants took a 90-minute walk in either nature or the city. Those who walked in nature reported significantly less brooding. Brain imaging also showed reduced activity in the subgenual prefrontal cortex. There were no changes for the city walkers -- in fact, they were more frazzled after their walk.
So today, we put the research into action. We closed our laptops and took a walk through a nearby walking trail by the U of A Augustana campus.
For people who work in agriculture, being outside for work and taking a few minutes to experience nature aren't always the same thing.
While time in nature isn't treatment on its own, taking a literal walk in nature can be one practical way to interrupt a loop of negative thinking and give your attention somewhere else to go.
