Snoring occurs when something restricts your airflow during sleep.
Several conditions and factors can block airflow. These include:
- Alcohol and other sedatives that relax muscles, restricting airflow.
- Bulky soft tissue, including enlarged adenoids, tonsils or tongue.
- Excess body fat, which puts pressure on the soft tissues and compresses the airway.
- Pregnancy hormones that cause inflammation in the nose.
