A dry cough can be annoying, disruptive, and sometimes confusing. Unlike a productive cough that brings up mucus, a dry cough feels tight, irritating, and persistent. Because it can stem from a wide range of conditions, from something mild and temporary to something more serious, it helps to understand what your body may be trying to signal. Knowing the most common causes can help you decide when to monitor your symptoms at home and when it’s time to seek medical attention.

Dry Cough From Viral Infections
Many respiratory viruses start with or include a dry, hacking cough. Colds, flu, RSV, and even COVID-19 can all irritate the throat and airway lining, causing a cough that lingers even after other symptoms improve. The cough happens because inflammation makes the airway more sensitive, triggering the urge to cough even when there’s no mucus present. If a dry cough is paired with fever, congestion, fatigue, or body aches, a viral infection is one of the most likely causes. While most viral coughs resolve on their own, a sudden spike in symptoms or trouble breathing should prompt a medical visit.
Allergies and Post-Nasal Drip
Seasonal allergies, dust, pet dander, and other environmental irritants commonly lead to dry coughing. When your immune system reacts to allergens, it can cause inflammation in your nose and throat. Even though post-nasal drip often involves mucus, it may not always be noticeable. Instead, the drip can simply irritate the throat, creating a tickle that triggers frequent coughing. Allergy-related dry coughs tend to worsen in certain environments or at night when lying down, and they may come with itchy eyes, sneezing, or throat irritation.
Asthma and Airway Sensitivity
Asthma isn’t always obvious, and in some people, a chronic dry cough may be the main symptom. Cough-variant asthma causes the airway to become inflamed and overly sensitive, resulting in a repetitive, non-productive cough. Symptoms often flare with exercise, cold air, allergens, or respiratory infections. Some people also experience chest tightness, wheezing, or shortness of breath, although these signs can be subtle. If your dry cough comes and goes in patterns or lasts more than several weeks, asthma may be the underlying cause and should be evaluated by a provider.
Irritants, Reflux, or Other Triggers
Dry coughing can be triggered by non-respiratory causes as well. Exposure to smoke, pollution, cleaning chemicals, or strong scents can irritate the throat and airway. Acid reflux, or GERD, can also cause a chronic dry cough when stomach acid reaches the esophagus and throat, leading to irritation. Less commonly, a persistent dry cough may develop from certain medications or as a sign of a more serious lung condition. If your cough lasts more than 3 to 4 weeks or interferes with sleep, it’s important to get checked to identify the underlying issue.
