In a clinical trial, researchers at the University of Sao Paulo Medical School in Brazil gave patients a set of daily isometric and isotonic exercises typically used in speech therapy.
According to the findings, those participants showed a significant decrease in sleep apnea symptoms, such as excessive snoring, at the end of three months compared to a control group.
Researchers say the set of exercises is a promising alternative treatment for moderate cases of OSA, but other experts in the field say more research needs to be done.
The study was published in the "American Journal of Respiratory and Critical Care Medicine".
