In this episode of the Merck Manuals Medical Myths Podcast, Dr. Richard Schwab, chief of the Division of Sleep Medicine at the University of Pennsylvania Pearlman School of Medicine continues to debunk sleep myths.  
 
The focus shifts from insomnia to snoring and sleep apnea. Dr. Schwab explains that snoring is caused by the vibration of the uvula or soft palate due to a narrow airway, often exacerbated by factors like alcohol and obesity. Dr. Schwab explains that while snoring is common, it is not normal and can be a sign of sleep apnea. In this condition, the airway narrows significantly, reducing airflow, oxygen levels, and associated cardiovascular risks.  
 
Dr. Schwab also discusses various treatments for sleep apnea, including CPAP machines, oral appliances, and surgical options like hypoglossal nerve stimulation. He emphasizes the importance of addressing chronic snoring and sleep apnea due to their significant impact on health and daily functioning.
