A tight cough in the morning with occasional runny nose later could be due to mild airway irritation or early signs of conditions like asthma or allergic rhinitis.

🩺 Possible Causes

• Postnasal drip or allergies: Mucus dripping down the throat overnight can cause morning cough and later nasal symptoms.
• Early asthma or airway hyperreactivity: Narrowing of airways often causes morning cough that improves during the day.
• Mild viral upper respiratory infection: Early cold symptoms can present this way.

🩺 What You Can Do

• Monitor if symptoms worsen or persist beyond a week.
• Avoid irritants like smoke or strong odors.
• Use a humidifier at night to ease airway dryness.

⚠️ When to See a Doctor

• If cough worsens, becomes persistent, or you develop wheezing or shortness of breath.
• If runny nose is severe or accompanied by fever.
• If symptoms interfere with daily activities or sleep.
