Abstract
En 中文
• Anxiety disorders are characterized by reduced voluntary breath-hold time, indicating diminished respiratory interoceptive tolerance. • Breath-hold time shows stronger associations with state anxiety and acute distress than with trait anxiety measures. • Respiratory protocol parameters (inhalation vs. exhalation onset) systematically modulate breath-hold performance across studies. • Sex composition predicts breath-hold time in healthy adults but not in anxiety samples, suggesting altered interoceptive processing in clinical populations. • Voluntary breath-hold time provides a simple performance-based marker of respiratory interoception relevant to anxiety vulnerability.
