One of the causes of snoring is the weakening of the muscles of the palate and pharynx.. Special vocal classes can train these muscles.

Otolaryngologist Malcolm Hilton decided to use these exercises for his research.. He collected 127 people suffering from chronic snoring and sleep apnea and divided them into two groups..

For 3 months, patients from the first group performed daily 20-minute muscle training exercises.. The sessions were quite simple and, according to the participants, they were easy to handle.. The second group did not study according to the system.

By the end of the experiment, it turned out that the volunteers who were engaged in the proposed program began to snore less often and quieter, and the quality of sleep improved.. The doctor published the results of the work in the scientific journal International Journal of Otolaryngology and Head and Neck Surgery.
