An ancient breathing practice involving conch shells could help ease the symptoms of obstructive sleep apnea (OSA), a condition affecting millions in the UK, new research suggests.
Known as conch blowing or shankh blowing, the ritual involves a deep inhalation followed by exhaling into the spiral-shaped shell. In a small trial, the practice appeared to improve sleep quality and daytime alertness for people with OSA, a disorder where breathing repeatedly stops and starts during sleep.
The study behind the findings
Researchers at the Eternal Heart Care Centre and Research Institute in Jaipur, India, recruited 30 people with OSA, aged 19 to 65. Half were trained in shankh blowing, while the other half performed deep breathing exercises. Both groups practised for at least 15 minutes, five days a week.
After six months, those in the conch blowing group reported feeling 34 percent less sleepy during the day. They also had higher nighttime oxygen levels and experienced, on average, four to five fewer OSA episodes per hour.
“Shankh blowing is a simple, low-cost breathing technique that could help improve sleep and reduce symptoms without the need for machines or medication,” said lead researcher Dr. Krishna K Sharma. He explained that the distinctive blowing action creates vibrations and airflow resistance, likely strengthening the muscles of the upper airway, including the throat and soft palate which are areas that tend to collapse during sleep in people with OSA.
How it compares to standard treatment
The most common OSA treatment is a continuous positive airway pressure (CPAP) machine, which uses pressurized air to keep airways open during sleep. While effective, CPAP masks can be uncomfortable, prompting researchers to explore alternatives. Previous studies have also linked playing woodwind instruments to symptom improvement.
Dr Sharma’s team believes conch blowing could offer a more accessible option for some patients, though he stresses that larger trials are needed. A multi-hospital study is already in the works.
Expert caution and next steps
Specialists are cautiously optimistic. “The findings of this trial are encouraging, but the small scale means it’s too soon to say for certain that conch blowing can help people manage their obstructive sleep apnea,” said Dr. Erika Kennington, head of research and innovation at Asthma + Lung UK.
Kennington also noted the need for more evidence on why the practice works and how it compares with proven strategies such as limiting alcohol, staying active, and maintaining good bedtime habits.
“OSA is a long-term condition, but with the right treatments and lifestyle changes, people can make a real difference to their symptoms,” she said.
