A Cough Doesn’t Always Mean You’re Sick
Coughing is one of the most common reasons people worry they’re sick—especially in winter. But not every cough is caused by an infection.
A cough is a reflex, not a diagnosis.
Common Reasons You May Have a Cough
Recent Illness
After a cold or flu, coughs can linger for weeks even after other symptoms improve.
Dry Air or Seasonal Changes
Cold, dry winter air can irritate the throat and airways, leading to coughing without illness.
Postnasal Drip
Mucus draining down the throat—often from allergies or congestion—can trigger coughing.
Acid Reflux
Reflux can irritate the throat, especially at night, causing a persistent cough.
Environmental Irritants
Smoke, dust, or strong scents can cause coughing even when you’re otherwise healthy.
Dry Cough vs. Productive Cough
- Dry cough: Often related to irritation or post-viral inflammation
- Productive cough: Helps clear mucus and may accompany infections
Neither automatically means something serious.
When a Cough May Signal Illness
A cough is more likely related to illness if it occurs with:
- Fever
- Shortness of breath
- Body aches
- Fatigue
- Worsening symptoms
When to Consider Seeing a Doctor
Contact a primary care provider if a cough:
- Lasts longer than a few weeks
- Gets worse instead of better
- Disrupts sleep or daily activities
- Comes with breathing difficulties
Why Primary Care Is the Right First Step
Primary care providers help determine:
- Whether a cough needs further evaluation
- If testing or imaging is necessary
- How to manage lingering symptoms
Most coughs resolve with time, but guidance helps avoid unnecessary worry.
