“Naak behna” in English means “runny nose.” The medical term is “rhinorrhea” (or rhinorrhoea). “Naak se pani aana” also means a watery runny nose. If the nose feels blocked, the English term is “nasal congestion” or “stuffy nose.”
Naak behna in English: quick meanings
- Naak behna / naak bahna: runny nose
- Naak se pani aana: watery nasal discharge or runny nose
- Naak band hona: blocked nose, stuffy nose or nasal congestion
- Sardi / nose sardi: common cold when caused by a viral infection; people also use “sardi” loosely for nasal allergy or weather-triggered symptoms
- Medical term: rhinorrhea; “rhinitis” means inflammation or irritation inside the nose
A runny nose is a symptom, not one single diagnosis. Cold air can trigger it, but viral cold, allergy and other irritants can look similar. The pattern of symptoms helps decide what is more likely.
Why does the nose run in cold air?
The nose warms and humidifies the air before it reaches the lungs. A sudden change in temperature or humidity can irritate the nasal lining and cause extra watery mucus. This weather-triggered response is often called cold-air rhinitis and may be part of non-allergic rhinitis.
Cold-air rhinitis is more likely when watery discharge begins soon after exposure to cold air and improves after returning to a warmer environment. It does not automatically mean infection, and it does not prove an allergy.
Runny nose: cold air, viral cold or allergy?
| Pattern | Clues that may fit |
|---|---|
| Cold-air or non-allergic rhinitis | Watery discharge or blockage triggered by temperature change, smoke, perfume or spicy food; eye itching may be absent. |
| Common cold | Runny or blocked nose with sore throat, cough, sneezing or feeling unwell; it usually improves on its own. |
| Allergic rhinitis | Repeated sneezing, itchy nose or eyes, watery eyes, and a pattern linked to wheat/grain dust, pollen, animals or another allergen. |
| Sinus or structural problem | Persistent one-sided blockage, recurrent facial pressure, reduced smell, repeated bleeding, or symptoms that do not follow a simple cold pattern. |
These are clues, not a self-diagnosis. Allergy and non-allergic rhinitis can coexist, and examination may be needed when symptoms persist.
Does yellow or green mucus mean bacterial infection?
No—not by itself. During a viral cold, mucus can normally become white, yellow or green. Colour alone does not show that antibiotics are needed. Seek medical assessment when symptoms are severe, keep worsening, improve and then become worse again, or persist without expected improvement.
Safe steps for a simple runny nose
- Drink enough fluids and rest if you also have cold symptoms.
- A ready-made saline nasal spray may help clear mucus. For a rinse bottle or neti pot, use only distilled, sterile, or previously boiled and cooled water. Do not use untreated tap water. Follow the device’s cleaning instructions and CDC guidance on safe nasal rinsing.
- Cover the nose loosely with a scarf or mask when moving into cold, dry air.
- Avoid tobacco smoke, strong perfume and other triggers that reliably worsen symptoms.
- Do not start antibiotics for a runny nose without a clinician’s advice; antibiotics do not treat viral colds.
- Do not keep using an over-the-counter decongestant nasal spray beyond the labelled duration. Overuse can cause rebound congestion.
Prescription nasal medicines are selected according to the cause and the dominant symptom. A dose that is suitable for one person may be unsuitable for a child, during pregnancy, with glaucoma or prostate problems, or alongside other medicines. This page therefore does not give a universal prescription or dose.
When should you see an ENT doctor?
- Symptoms are persistent, recurrent or affecting sleep and daily activity.
- The blockage or discharge is repeatedly one-sided.
- There is recurrent bleeding, a bad smell, facial swelling, marked facial pain or reduced sense of smell.
- There is high fever, breathing difficulty, dehydration, unusual sleepiness, or rapid worsening.
- A young child has difficulty feeding or breathing, or a foreign object may be inside one nostril.
Urgent or emergency symptoms should be taken to an appropriate emergency service; the clinic contact number is not presented as an emergency line.
