Daily Breathwork
Slow breathing, 5 to 10 minutes daily. Raises vagal tone and steadies sleep.
What it does
Slow breathing directly stimulates the vagus nerve and shifts autonomic balance toward parasympathetic dominance, with effects measurable within minutes. Among the highest-ROI interventions per minute — no equipment, no cost, only the discipline to do it.
Slow, exhale-emphasized breathing stimulates the vagus nerve via the diaphragm and baroreceptor pathway, shifting the autonomic system toward parasympathetic dominance and lowering heart rate and blood pressure.
What the evidence shows
Overall evidence strength: Moderate certainty
Who it's for, who should skip
Anyone wanting a fast, free autonomic reset. ~5–6 breaths per minute with longer exhales than inhales; the branded proprietary protocols are mostly optional dressing on that core mechanism.
