Of all the mindfulness-adjacent techniques, controlled breathing has arguably the most immediate and well-documented physiological effects. Slow diaphragmatic breathing (5–6 breaths per minute) directly activates the vagus nerve, triggering the parasympathetic "rest and digest" response. Heart rate drops, blood pressure decreases, and cortisol production is reduced within minutes.

Many mouth taping practitioners prefer 3M's Nexcare or Micropore paper tape — applying a small H-shaped or vertical strip across the lips (not a complete seal). This is the most affordable approach and allows easy removal. Paper medical tape is gentle on skin, widely available, and used by many experienced mouth tapers who have found the SomniFix vent allows too much mouth breathing. The key is applying a gentle, partial lip seal rather than taping the entire mouth.
