A dry cough can be frustrating, especially when it interrupts your sleep, irritates your throat, or sticks around longer than expected. Unlike a wet cough, a dry cough doesn’t produce mucus, meaning the irritation usually comes from your throat or airway lining. Whether you’re dealing with seasonal changes, a lingering viral infection, or throat dryness at night, simple home remedies can offer much‑needed comfort.
Below, you’re getting a friendly, research‑supported guide to 15 effective home remedies for dry cough, what causes it, and what actually helps.
