I don’t practice mindfulness, and I’m certainly not a neuroscientist. That said, from the study linked in the article you referenced to I don’t get the conclusion that the exact opposite has been proven true. I can see roughly 1/4 of participants reported bad experiences that they attributed to mindfulness, but I found nothing about the other 3/4. Did the feel no difference? An improvement? Without that, I don’t reach the same conclusion as you.

Given I’m just a layperson, can you help me understand what I am missing here?
