A study carried out by the Royal Devon and Exeter Hospital has proved that snoring can be reduced simply by singing.

For three months, the patients in the clinical trial have been doing singing exercises to improve the tone of their throat muscles.

Choir director Alise Ojay is the inventor of Singing for Snorers exercises.

She told Today presenter Evan Davis that she had found that patients who sung the sounds "ung" and "gar" found that their snoring decreased or stopped.
