Hiccups, asthma, cough, headache, ear pain, and eye pain — these and other various diseases arise from disturbance of the wind.

This verse details the specific symptoms that can arise from incorrect prāṇāyāma practice (pavanasya prakopataḥ — disturbance of the wind/prāṇa):

• Hikkā — hiccups, diaphragm spasms
• Śvāsa — breathing difficulty, asthma
• Kāsa — cough
• Śiraḥ-vedanā — headache
• Karṇa-vedanā — ear pain
• Akṣi-vedanā — eye pain

And vividhāḥ rogāḥ — “various diseases” more.

The list is significant because all these symptoms are related to pressure, tension, and imbalance in the head, chest, and nervous system regions — exactly the areas affected by forced breath retentions.

If any of these symptoms appear during or after practice, it is a signal to adjust technique, reduce intensity, or consult with an experienced teacher.
