Obstructive sleep apnea happens when the muscles of the upper airway relax too much during sleep, temporarily blocking airflow. Even though the body continues trying to breathe, oxygen levels may drop and sleep can become fragmented throughout the night. This repeated cycle prevents restful sleep and can place strain on the body over time.
The condition ranges from mild to severe, and treatment depends on a proper diagnosis. Identifying sleep apnea early can help reduce symptoms and improve overall quality of life.
