    Definition

    In an acute panic attack, deep or rapid breathing typically lowers blood CO₂ further, intensifies dizziness and tingling, and amplifies the panic loop instead of breaking it.

    The hyperventilation paradox

    A panic attack is already a state of over-breathing. Adding deeper or faster breaths drives CO₂ even lower, which causes the symptoms that scare you most — dizziness, tingling, blurred vision, racing heart.

    The better instruction

    Slow and small, not big and deep. Long exhales, gentle nasal inhales. Counted breaths if it helps focus.

    What to say to someone in panic

    Not “take a deep breath” but “breathe slowly out with me.” Then exhale together for 6–8 seconds. Repeat.

    When deep breathing is fine

    For everyday stress, deep diaphragmatic breaths are useful. The paradox only applies in acute hyperventilation.
