Slow-paced breathing is an effective tool for cardiac vagal activation. Most slow-paced breathing exercises can stimulate the vagus nerve, but I came across 2 small studies where the 4-4-6-2 breathing pattern led to measurable vagus nerve stimulation: Inhale 4 seconds Hold 4 Exhale 6 Hold 2 In both cases, participants were guided by experienced breathwork or yoga instructors, who helped ensure they practiced with the right rhythm and awareness.
