Staying hydrated by ingesting plenty of drinks aids in mucus thinned. A humidifier provides moisture to the air, which reduces congestion. Saline nasal rinses assist in cleansing nasal passages, while steam inhalation and warm showers remove mucus. Sleeping with your head elevated decreases nasal congestion, and nasal strips can help airflow. Gargling with warm seawater relieves throat pain and minimizes mucus buildup.
