1. Ensure adequate fluid intake.

Adequate fluid intake is one of the most effective ways to loosen mucus. Drinking water regularly helps to thin the mucus, making it easier to cough up. When dehydrated, the mucus becomes thick and sticky, which worsens the symptoms. Warm drinks such as ginger, chamomile, or peppermint tea are particularly helpful, as the warmth relaxes the airways and soothes the throat.
