Blowing into a conch might be more effective in easing symptoms of sleep apnoea -- in which one faces trouble breathing properly during sleep -- compared to deep breathing exercises, according to researchers from Jaipur in Rajasthan.

Obstructive sleep apnoea is marked by muscles in the throat which relax and narrow one's airways during sleep, thereby impacting breathing and oxygen levels in the blood. This results in a poor quality of sleep and fatigue or sleepiness during the day.

The team, led by researchers from the Eternal Heart Care Centre and Research Institute, looked at 30 people, aged 19-65 and having moderate obstructive sleep apnoea.
