Why breathing out through your mouth plays a significant role in emotional trauma healing:
( 1 minute read )
Mouth exhalation is used in mindful breathing and healing therapies (like somatic therapy, breathwork, and some forms of meditation) due to its physiological and psychological effects. Hereās how and why it helps:
ā
1. Triggers the Parasympathetic Nervous System (Relaxation Response)
⢠Exhaling slowly through the mouth (especially with a sigh or āhaaaā sound) signals safety to the body.
⢠This activates the parasympathetic nervous system, helping to calm the heart rate, lower blood pressure, and reduce cortisol (stress hormone).
⢠Result: You feel relaxed, grounded, and safe.
ā
2. Promotes Emotional Release
⢠Mouth exhalation allows for more expressive and full releases, which is why itās used in trauma-informed breathwork.
⢠Exhaling with sound (e.g., sighs, hums, or gentle moans) helps discharge stored tension or emotional energy in the body.
⢠This is key in healing practices like somatic experiencing or bioenergetic breathing.
ā
3. Enhances Awareness and Intentionality
⢠Breathing out through the mouth feels deliberateāunlike automatic nasal breathing.
⢠It increases mindfulness by encouraging you to slow down and stay present.
⢠Therapists often guide clients to ālet go with the exhale,ā making each breath a conscious release.
ā
4. Regulates COā and Oxygen Balance
⢠A longer, controlled mouth exhale helps optimize carbon dioxide retention, which can be calming and improve oxygen delivery to tissues (via the Bohr effect).
⢠This can be therapeutic in practices like coherent breathing or pranayama, when guided properly.
ā
5. Physical Relaxation
⢠Tension is often held in the jaw, throat, and diaphragm. Mouth breathing can help relax these areas when practiced mindfully.
⢠A soft exhale helps relax the vagus nerve, supporting rest, digestion, and emotional balance.

š Common Practices That Use It:
⢠Box breathing: Inhale (nose), hold, exhale (mouth), hold.
⢠Somatic therapy: Uses sighing, sounding, or shaking during exhalation.
⢠Yoga breathwork (Pranayama): Sometimes includes audible exhales (e.g., ālionās breathā).
⢠Trauma release work: Often emphasizes exhaling through the mouth with sound to support processing.
š Final Thought:
Mouth exhalation isnāt inherently ābetterā than nasal exhalationāitās just different, and in therapeutic or mindful contexts, it can be deeply regulating and healing when used with intention. Think of it as a way to tell your nervous system: āItās okay to let go now.ā
