Continuous Positive Airway Pressure (CPAP) is a medical treatment commonly used for individuals with sleep apnea, a condition where breathing repeatedly stops and starts during sleep. CPAP machines deliver a steady stream of air through a mask that keeps the airways open, preventing interruptions in breathing. The therapy helps improve sleep quality and reduces daytime fatigue by ensuring that the airway remains unobstructed. CPAP is often recommended by healthcare providers and can significantly enhance the overall health and well-being of those affected by sleep apnea.
