Restorative (Adjective): capable of renewing health or strength

“In an analysis of research on how nature keeps us calm, Atlantic writer Adam Atler explains why being outside is like hitting the reset button on our brains. The key, he writes, is through a psychological process known as attention restoration theory:” “This is your brain on Nature” -Lindsey Holmes.

When I stopped at this word, I was a bit confused but also had a clear guess on what this word means. Just because in Restoration, the word Restore is in it, giving a hint to the readers. Since the passage is about how our brain can be affected by nature, the word restore is the best way to describe how nature connects to our brain.
