I read an article today saying that walking, in nature specifically, helps cease anxiety and rumination. Rumination is defined as repetitive thoughts that focus on the negative aspects of yourself. I do have a lot of negative thoughts where I rehash things from the past that were hurtful or embarrassing, and have always found a walk in nature to be very helpful with that. I love to hike and backpack, have since I was a kid, and I love that this hobby is so beneficial! The way that they did the study was extremely interesting as well- along with a questionnaire, the participants also had their brains scanned with a neural imaging technique that allowed the researchers to measure how much blood was flowing through the subgenual prefontal cortex, which is an area of the brain that lights up when a person engages in rumination. The article is from Los Angeles Times if anyone is interested! The article does date back to July 2015, but still an interesting read for people who love to hike or those who experience rumination at all.
