A dry cough (non-productive cough) results from airway irritation, often triggered by viral infections (cold, flu, COVID-19), allergies, asthma, or postnasal drip. Other common causes include acid reflux (GERD), environmental irritants (smoke, dust, dry air), and side effects from certain medications (ACE inhibitors). Persistent dry coughs can also signal conditions like sleep apnea, laryngitis, or, rarely, heart failure or lung issues, highlighting the need for diagnosis.
A dry cough is a cough that doesn't produce mucus. When your airways or lungs are inflamed, a tickly, irritated feeling causes you to cough. If you don't have mucus (usually produced when you have an infection), it will be a dry, unproductive cough. Common causes include allergies, asthma, acid reflux and bronchitis.
If the cough is due to common cold or flu then in most cases, it can be treated with home remedies and OTC medications. Most patients are able to suppress dry cough with honey, ginger, steam inhalation, or a humidifier. They alleviate the irritation in your throat and give you instant relief.
Hence, a person who is already suffering from cough and cold should avoid foods that are rich in histamines. Some foods to avoid are avocados, mushrooms, strawberries, dry fruits, alcohol, yogurt, vinegar and fermented foods.
