Voluntary Slow Breathing: Using an app (or counting) to deliberately breathe slowly at a set pace (like five breaths a minute).
Physiological Slow Breathing: Using mindfulness or a relaxation technique (like yoga nidra) to put your physiology in a state where slow breathing occurs naturally.
Of course, they have slightly different benefits, but either will be an effective way to improve your health & wellness, so pick the one that suits you best 🙏
