Episode notes
First Act At Birth: Check The Tongue
- Zoroush Zaghi checked his newborn son for a tongue tie immediately after birth and found one.
- He treated the tie on day two with a 12-second procedure while the baby was awake.
Tongue Position Controls Airflow Efficiency
- Tongue position critically affects airway resistance and nasal breathing efficiency.
- A high tongue seals the mouth-to-nose airway and lowers resistance while a low tongue increases upper airway resistance.
Prefer Nasal Breathing
- Breathe through your nose to humidify, warm, and filter inhaled air.
- Avoid habitual mouth breathing to reduce dry mouth, inflammation, and immune exposure.
