It may seem hard to believe that journaling can impact your overall physical health, yet recent studies have shows that it is more than possible. If you kept a diary as a teenagers, you know how good it feels to drop off your thoughts on paper.
LET’S talk about the BRAIN. On a neurological level, a brain that worries all the time is constantly multitasking. Worrying is like an extra activity that you are doing (on top of your to do list), and it takes up energy as a portion of your cognitive efforts are working on suppressing the worries.
An experimental study conducted at Michigan State University shows that “if you get these worries out of your head through expressive writing, those cognitive resources are freed up to work toward the task you’re completing and you become more efficient” Schroder said.
The experiment was conducted with college students that suffered from anxiety. The students did computer-based “flanker task” that measured their response accuracy and reaction times. They were split into two groups. One group took time before the test to write down their deepest thoughts and feelings about the upcoming task for eight minutes; the other groups wrote about what they did the day before. Both groups performed at about the same level for speed and accuracy, however the expressive-writing group was more efficient and used fewer brain resources, as measured with EEG.
