How Stress Affects the Brain

“Your brain reflects the way that you think throughout your life. You kind of shape it by your thoughts and your behaviors. If you play violin for eight hours a day, then the parts of the brain responsible for helping you to play the violin will get larger. If you’re thinking stressful thoughts for the whole day then those parts of the brain are going to get larger and other parts of the brain will deteriorate. It’s kind of an irony because then the very brain circuits that we would need to try and counter that are no longer working as well as they should, so that’s why something like meditation can be helpful because just simply saying, “Oh, I’m going to change how I think now. I’m not going to be as stressed now,” doesn’t really work; you have to change your brain over a long period of time.”
