TAP reading note: Comparing the Effects of Square, 4–7-8, and 6 Breaths-per-Minute Breathing Conditions on Heart Rate Variability, CO2 Levels, and Mood
Six-breaths-per-minute conditions increased HRV more than square or 4–7–8 breathing during practice. The experiment did not establish a meaningful mood or blood-pressure benefit; mild over-breathing occurred with the six-breath conditions.
