Could blowing a conch shell help you sleep better?
According to a small randomized controlled trial published in ERJ Open Research, researchers say conch blowing is a simple, low-cost intervention that could help reduce symptoms without the need for medication or machines.
The practice is also known as shankh blowing, which has been part of Indian culture for thousands of years.
For 6 months half the participants practiced shankh blowing for 15 minutes, 5 days a week—the rest did deep-breathing exercises.
The shankh group saw:
• 34% less daytime sleepiness
• 4–5 fewer breathing pauses per hour during sleep
• Higher overnight blood oxygen levels
Researchers believe this technique strengthens upper airway muscles (throat, soft palate) through vibrations and airflow resistance, potentially keeping your airway more stable while you sleep.
