Trauma is uncomfortable to bring up in conversation. You don’t often hear about it, despite the fact that 60 percent of adults report some kind of abuse or trauma in their childhood. You hear even less about tools to heal trauma — to uncover it, face it, feel the pain associated with it, and then let it go. The lack of discussion around trauma is partly cultural, but it’s also because trauma is hard to pin down. It’s so overwhelming that your brain often tries to bury it; it’s too painful to face, so you push it down or rationalize it and continue with your life. That works in the short-term, but in the long-term, buried trauma can impact your stress response, cause chronic cortisol release, decrease your emotional regulation, and bring up a variety of coping behaviors that hurt your performance. By the same token, healing your childhood trauma is one of the most extraordinary biohacks you can do. It unlocks happiness, gratitude, optimism, productivity, and a renewed appreciation for life.
