Which breathing technique is commonly taught to reduce acute anxiety?

• A. Nasal breathing with breath-holding.
• B. Diaphragmatic breathing (slow, deep breaths) to reduce autonomic arousal.
• C. Rapid shallow breathing to increase arousal.
• D. Hyperventilation technique.

Answer: (B)

Slow, deep diaphragmatic breathing directly calms the body by shifting the autonomic nervous system toward the parasympathetic (rest-and-digest) side. When you breathe slowly and deeply with the diaphragm, you increase tidal volume, slow the breathing rate, and enhance vagal (parasympathetic) activity. This lowers sympathetic arousal—heart rate, blood pressure, and the overall sensation of panic—helping to reduce acute anxiety. It also improves CO2/oxygen balance, counteracting the tendency to hyperventilate that often accompanies anxiety. Other options don’t produce the same calming effect. Rapid shallow breathing tends to keep arousal high and can perpetuate anxiety. Hyperventilation techniques lower CO2 and can worsen dizziness and tingling, making anxiety feel worse. Nasal breathing with breath-holding can be uncomfortable and may provoke sympathetic activation or dizziness if not done carefully. Diaphragmatic, slow breathing is the most reliable, accessible method for reducing acute autonomic arousal.
