Shankh blowing is an ancient Indian practice used by yogis for thousands of years, and involves deep inhalation followed by forceful exhalation through a conch shell. But scientists now believe the technique could have huge benefits for those suffering from obstructive sleep apnoea (OSA) – a relatively common condition in which airways become blocked at night, interrupting peaceful breathing.

A study published in ERJ Open Research yesterday shows that people with moderate OSA who practised shankh blowing slept better, felt more alert during the day and had fewer breathing interruptions at night.

Researchers are now arguing the ancient method could be a simple and cheap way to reduce symptoms without the need for medication or machines.
