Runny Nose and Sneezing: Cold vs Allergy, and What to Do
Naak baar baar bahna could mean a cold that clears in a week, or an allergy that comes back every time the fan is dusty. They need different handling, and mixing them up is why some people take antihistamines for months with no real reason.
Quick facts
- Cold: comes with sore throat, mild fever, body ache, clears in 7 to 10 days
- Allergy: itchy eyes and nose, sneezing fits, worse around dust, pollen or pets, no fever, lasts as long as exposure continues
- Discharge colour: not a reliable way to tell infection from allergy on its own
- Both: respond to saline rinse and steam for symptom relief

Cold or allergy: the real tells
A cold usually starts with a scratchy throat, then congestion, then a few days of feeling generally unwell, sometimes with a mild fever and body aches. It runs a course and is mostly finished within a week to ten days. An allergy, on the other hand, tends to start suddenly on exposure to a trigger, brings itching in the nose, eyes and roof of the mouth that a cold rarely causes, and produces long sneezing fits rather than the occasional sneeze. It has no fever attached. If your nose runs every single morning near the same dusty cupboard or every spring, that pattern points to allergy, not a string of colds.
Myth: yellow or green discharge always means infection
This is one of the most repeated pieces of wrong advice. Nasal discharge naturally turns thicker and more coloured as white blood cells do their work, in both viral colds and, less commonly, allergies with some irritation. Colour alone does not tell you whether antibiotics are needed. Doctors look at how long symptoms have lasted, whether they are getting worse after day 7 instead of better, and whether there is facial pain or fever, not just the colour of what comes out.
What actually helps a cold
- Saline rinse: mix half a level teaspoon of salt in 250 ml of clean, cooled boiled or filtered water. Use a neti pot or bulb syringe, tilt the head, rinse one nostril at a time, 2 to 3 times a day.
- Steam: lean over a bowl of hot water, not boiling, with a towel over your head for 5 to 10 minutes, once or twice a day. Keep 30 cm distance to avoid a burn.
- Fluids and rest. Warm water, yakhni, or plain soup, several times a day.
- Honey in warm water for a sore throat, for anyone over 1 year of age. Never give honey to a baby under 1.
Face masks and pollution as an added trigger
In cities with heavy traffic pollution or seasonal crop burning, airborne irritants can worsen both cold-type and allergy-type nasal symptoms even without a true infection or classic allergen present. A well-fitted mask on high-pollution days, keeping windows shut during the worst hours of smog, and an air purifier in the bedroom for anyone with persistent symptoms can meaningfully reduce the daily irritant load, alongside the saline and antihistamine steps already described.
What actually helps an allergy
Identify and reduce the trigger where you can: wash bedsheets weekly in hot water, use a dust cover on pillows, keep pets out of the bedroom, and rinse the nose with saline after being outdoors on a high-pollen day. An antihistamine tablet (like cetirizine or loratadine) taken as directed on the pack, or as a doctor advises, controls sneezing and itching for most people within a day or two. It treats symptoms, not the underlying sensitivity, so it needs repeating each time exposure happens.
Steam and saline-type nasal rinsing appear across Unani and Ayurvedic household practice for a “thanda” or cold-pattern nose, often alongside warm foods and avoiding cold drinks during the episode. This is longstanding household wisdom for comfort, not a claim that it shortens either a cold or an allergy.
When it has tipped into sinusitis
Suspect sinusitis, not a simple cold, if congestion and thick discharge last more than 10 days without improving, if there is pain or pressure around the cheekbones or forehead that gets worse bending forward, or if a fever returns after initially settling. That pattern needs a doctor’s assessment rather than more home steam.
Children and a runny nose
Infants cannot blow their own nose, and a blocked nose interferes with feeding since babies breathe mainly through the nose while suckling. Saline drops, 2 to 3 in each nostril, followed by gentle bulb suction, done just before a feed, clears enough congestion for most babies to feed properly. Steam is not recommended for infants because of burn risk. Toddlers and older children can usually manage a saline spray or rinse the same way adults do, though the smaller volume and a gentler technique help avoid discomfort. Fever alongside a runny nose in a child under 3 months always needs same-day medical attention.
Dust and household triggers worth checking
In many desi homes, the biggest year-round allergy trigger is not pollen but house dust mites living in mattresses, pillows and old quilts, along with mould in poorly ventilated bathrooms and damp storage areas. Vacuuming mattresses monthly, airing quilts and pillows in the sun regularly, and fixing any damp patches in the home reduce exposure meaningfully over weeks, more reliably than any single remedy taken during a flare. Cooking smoke and incense can also irritate a sensitive nose and are worth noting in the trigger diary above.
Decongestant sprays: useful, but not for long
Over-the-counter decongestant nasal sprays give fast relief in adults but should not be used for more than 3 to 5 consecutive days, and they aren’t for children under 6. Beyond that, they can cause rebound congestion, where the nose becomes more blocked once the spray is stopped, sometimes worse than the original problem. Saline spray has no such limit and can be used daily for as long as needed.
Humidity and the bedroom at night
Very dry indoor air, common with air conditioning or heating running overnight, can thicken nasal mucus and worsen morning congestion whether the underlying cause is a cold or an allergy. A simple bowl of water near a heater, or a humidifier kept clean and refilled daily to avoid mould growth inside it, keeps the nasal lining more comfortable through the night for many people.
| Feature | Common cold | Allergy |
|---|---|---|
| Fever | Sometimes, mild | No |
| Itchy eyes/nose | Rare | Common |
| Duration | 7 to 10 days | As long as exposure |
| Sneezing pattern | Occasional | Long fits |
See a doctor if symptoms last beyond 10 days without improvement, if there is facial pain, a fever returning after it had settled, blood in the discharge, or breathing difficulty. Children under 2 with a persistent runny nose and fever should be seen rather than treated at home. Anyone with asthma whose allergy symptoms are worsening their breathing needs prompt review, since the two conditions interact. Antihistamines can cause drowsiness; check the label before driving. For young children, use an allergy antihistamine only through a pharmacist or doctor, who sets the dose by weight.
Frequently asked questions
How do I know if it’s a cold or an allergy?
Itching in the nose, eyes or roof of the mouth, long sneezing fits and no fever point to allergy, especially if it flares near dust, pets or pollen. A cold usually starts with a scratchy throat, may bring mild fever and aches, and clears in 7 to 10 days.
Naak behne ka ilaj without medicine, does it exist?
For most runny noses, saline rinses, steam, rest and warm fluids are what genuinely help. They won’t shorten a viral cold, but they make the days far more comfortable.
How do I make saline water for a nose rinse at home?
Stir half a level teaspoon of salt into 250 ml of boiled and cooled, or filtered, water. Rinse one nostril at a time with a neti pot or bulb syringe, two or three times a day. Don’t use plain tap water straight from the tap.
Does yellow or green mucus mean I need antibiotics?
Colour on its own doesn’t tell you that. Mucus thickens and changes colour during ordinary colds too. What matters is symptoms lasting over 10 days, getting worse after day 7, facial pain or a fever that comes back.
Do antihistamines cure the allergy?
They don’t. Tablets like cetirizine or loratadine control sneezing and itching while you take them. Cutting down the trigger, dust mites, pollen or pets, is what reduces how often you need them.
How do I clear a baby’s blocked nose?
Put 2 to 3 saline drops in each nostril, then use gentle bulb suction, just before a feed. Skip steam for babies because of burn risk. Any fever in a baby under 3 months needs same-day medical care.
Can I give cold medicine to my child?
Over-the-counter cough and cold medicines aren’t for children under 6. Saline drops or spray and fluids are the safer route. For antihistamines in children, follow a doctor’s guidance rather than adult doses.
When does a runny nose become sinusitis?
Suspect it when congestion and thick discharge last beyond 10 days without improving, when there’s pressure around the cheeks or forehead that worsens as you bend forward, or when fever returns after settling. That needs a doctor.
Can I use saline rinse every day long term?
Yes. It’s generally safe for daily use in adults and in children old enough to tolerate it, and many people with ongoing allergies make it a routine habit.
How long can I use a decongestant nasal spray?
No more than 3 to 5 days in a row. Longer than that and the nose can rebound, becoming more blocked when you stop. Saline spray has no such limit.
Why does my nose run every morning?
A runny nose every morning often means dust mite allergy from pillows, mattresses and old quilts, or dry air from the AC or heater overnight. Hot-wash sheets weekly, sun quilts and pillows, and keep bedroom air from drying out.
When should a child with a runny nose see a doctor?
Any fever in a baby under 3 months needs same-day care. A child under 2 with a runny nose that keeps going plus fever should be seen rather than treated at home, and so should any child who is struggling to breathe, not feeding or unusually drowsy. Symptoms beyond 10 days without improvement also deserve a check.
