Sleep apnea is a common sleep disorder where breathing repeatedly stops and starts during sleep, often causing poor rest and long-term health risks. CPAP (Continuous Positive Airway Pressure) therapy is a leading treatment that uses a machine to deliver constant airflow through a mask, keeping the airway open. Choosing the right mask is crucial for comfort and effective therapy, as compatibility with the CPAP machine ensures proper function and prevents air leaks. While masks can sometimes be worn alone for adjustment purposes, they are only effective when connected to the device. CPAP therapy greatly improves sleep quality and overall health.
