3. Obstructive Sleep Apnea

Obstructive sleep apnea or OSA is a primary cause of snoring. In most people, sleeping restricts airflow to specific areas in the upper respiratory tract, due to a combination of normal muscle relaxation and gravity. People with sleep apnea have even less airflow, and the airways collapse for seconds at a time before reopening, causing snoring. This is a potentially dangerous illness, but sleep masks and other treatments can correct it. Weight loss can also help, as the condition is common in people with obesity.
