Why Healthy Boundaries Are About Safety, Not Control

One of the most common statements I hear in the therapy room is:

For years I’ve taught humming breath as a grounding tool. I knew it helped—clients often told me they felt calmer after humming—but I didn’t fully understand why. Tonight I watched a video that pulled the science together, and it felt like the missing pieces fell in place: humming isn’t just soothing by chance, it engages the vagus nerve and the body’s parasympathetic system in several measurable ways.

Understanding the vagus nerve is one of the most important parts of understanding trauma, anxiety, chronic stress, and healing.
