Overview

• The six-month randomized study in Jaipur reported a 34% reduction in daytime sleepiness and four to five fewer apnoeas per hour among participants practicing shankh blowing.
• Forceful exhalation through the spiraled conch shell generates airflow resistance and vibrations that likely strengthen upper airway muscles prone to collapse in OSA.
• Originating from ancient Indian yogic rituals, shankh blowing offers a simple, culturally embedded breathing exercise that requires minimal equipment.
• While CPAP remains the gold-standard therapy for OSA, many patients struggle with its discomfort, affordability and long-term adherence.
• Following ethical approval, the forthcoming multicenter trial will evaluate effects on airway muscle tone, oxygenation and sleep architecture as a potential adjunct or alternative to CPAP.
