A dry cough is a persistent, irritating cough without mucus, often caused by viral infections, allergies, GERD, asthma, medications, or environmental triggers like pollution and smoke. Symptoms include throat irritation, hoarseness, constant tickling, and chest discomfort. While simple remedies like warm fluids, steam inhalation, and humidifiers can offer relief, a chronic dry cough lasting over 3–8 weeks may indicate underlying conditions such as asthma, GERD, bronchitis, or even heart issues.
If symptoms persist, worsen at night, or are accompanied by chest pain, blood, or weight loss, it’s important to consult a doctor.
