Is it a Cold or Spring Allergies? Understanding Respiratory Issues in Late Winter
It is that time of the year in Kolkata. The morning air still has a slight nip to it, forcing you to wrap a light shawl around your shoulders. But by noon, the sun is blazing, the fans are back on, and the city is blooming with the vibrant reds of Palash and Shimul flowers.
This transition from winter to spring—often called Vasant Ritu—is beautiful, but it comes with a hidden cost. For many of us, it marks the start of the “sneeze season.” You wake up with a stuffy nose. Your throat feels scratchy. You feel tired.
Immediately, the questions start swirling in your head: “Did I catch a chill from the fan last night?””Is this a viral fever?””Or is it just the dust and pollen in the air?”
At Eskag Sanjeevani Hospitals, our waiting rooms see a surge of patients in February and March asking these exact questions. Confusing a common Cold with seasonal allergies is easy to do, but treating them requires very different approaches. Mistaking one for the other can prolong your suffering and potentially worsen underlying respiratory issues.
In this guide, we will break down the science of late-winter sniffles, helping you decode your symptoms so you can breathe easier.
Key Takeaways
- Respiratory issues in late winter often mimic each other; distinguishing between a viral Cold (fever, body ache) and spring allergies (itchy eyes, clear mucus) is crucial for the right treatment.
- Ignoring persistent symptoms like breathlessness or wheezing can lead to severe complications like respiratory failure, especially in seniors and those with asthma.
- If over-the-counter remedies fail after a week, consulting a doctor for respiratory problems at Eskag Sanjeevani is necessary to rule out chronic respiratory diseases.

The Confusion: Why Late Winter Triggers Respiratory Issues
Why does everyone seem to get sick right now? The answer lies in the unique “sandwich” weather of Kolkata in February.
- Temperature Fluctuation: The drastic shift from cold nights to hot days weakens our immune system’s first line of defense—the nose. This makes us more susceptible to viral infections, leading to a rise in respiratory issues.
- The Pollen Explosion: As flowers bloom, trees release billions of tiny pollen grains into the air. For sensitive lungs, these act as invaders.
- Dust and Pollution: The dry winter wind lifts dust and pollutants, creating a cocktail of irritants that can trigger respiratory diseases like asthma or bronchitis.
This combination creates a “perfect storm” for your lungs. But how do you know if it is a virus or just the air?
Team Cold vs. Team Allergy: Spotting the Difference
To manage your respiratory issues effectively, you need to be a bit of a detective. While symptoms overlap, there are distinct clues.
1. The Onset (How it Starts)
- The Cold: It usually creeps up on you. You might feel a bit tired one evening, have a sore throat the next morning, and then the runny nose starts. It evolves over 1-2 days.
- Spring Allergies: Bam! It hits you all at once. You walk into a dusty room or a park, and suddenly you are sneezing uncontrollably. The symptoms appear immediately after exposure to a trigger.
2. The Itch Factor
The Cold: You rarely feel itchy. You mostly feel sore or heavy.
Spring Allergies: This is the biggest giveaway. If your eyes are watery and itchy, the roof of your mouth tingles, or your nose feels like it needs a good scratch, it is almost certainly an allergy. Viruses typically don’t cause itchiness.
3. The Fever Check
The Cold: A mild fever (around 99°F – 100°F) is common, especially in children. It indicates your body is fighting a virus.
Spring Allergies: Never cause a fever. If you are running a temperature, it is not just pollen; you have an infection causing your respiratory issues.
4. The Mucus Test (Gross, but Useful)
The Cold: Starts clear, but often turns thick, yellow, or green after a few days. This shows your immune system is battling a virus.
Spring Allergies: The discharge is usually thin, watery, and clear. It stays that way unless you develop a sinus infection.
5. Body Aches and Pains
The Cold: Often comes with that “hit by a truck” feeling—muscle aches, headache, and general fatigue.
Spring Allergies: You might feel tired from sneezing, but you won’t have deep muscle aches.
Why You Should Not Ignore “Just a Sneeze”?
We often dismiss these symptoms. “It’s just a cough, it will go away.” While a common Cold usually resolves in 7-10 days, untreated allergies or viral infections can escalate into serious respiratory diseases.
The Risk of Sinusitis
When your nasal passages are swollen due to allergies for weeks, mucus gets trapped. This stagnant mucus becomes a breeding ground for bacteria, turning a simple allergy into a painful bacterial sinus infection.
Asthma Flare-Ups
For those with asthma, this season is dangerous. The same pollen that causes a sneeze in one person can cause an asthma attack in another. Ignoring early signs of respiratory issues—like a mild wheeze or chest tightness—can lead to a severe emergency requiring hospitalization.
The Danger of Respiratory Failure
In elderly patients or those with COPD (Chronic Obstructive Pulmonary Disease), a simple viral Cold can travel down to the lungs, causing pneumonia. If not treated by a specialist doctor for respiratory problems, this can lead to respiratory failure—a condition where the blood doesn’t get enough oxygen. This is life-threatening and requires immediate ICU care.
Management Guide: Handling the Cold
If your detective work points to a Cold, your goal is comfort and rest. Since it is viral, antibiotics will not work.
- Rest: Your body needs energy to fight the virus.
- Hydration: Warm soups, herbal teas, and water help thin the mucus.
- Steam Inhalation: The best natural remedy for blocked noses.
- Patience: It will pass in a week.
Management Guide: Handling Spring Allergies
If it is spring allergies, you need to stop the reaction.
- Avoid Triggers: Keep windows closed on windy days when pollen counts are high. Wear a mask when cleaning or going out in traffic.
- Wash Up: Shower and change clothes after coming home to wash off pollen trapped in your hair and fabric.
- Medication: Antihistamines (anti-allergy pills) work best if taken before you are exposed. Nasal sprays can reduce inflammation.
When to See a Respiratory Medicine Doctor?
Self-diagnosis has its limits. You should stop home remedies and search for a “doctor for respiratory problems” or visit Eskag Sanjeevani if:
- Duration: Symptoms last longer than 10 days with no sign of improvement.
- Severity: You have trouble breathing, wheezing, or a high fever (above 102°F).
- Color: You are coughing up blood or thick, rusty-colored mucus.
- Pain: You have severe chest pain or ear pain.At Eskag Sanjeevani Hospitals, our respiratory medicine doctor team uses advanced diagnostic tools like Spirometry (lung function tests) and high-resolution CT scans to look deep into your lungs. We don’t just treat the sneeze; we find the root cause of your respiratory issues.
Chronic Respiratory Diseases: The Silent Threat
Sometimes, what looks like a recurring cold is actually a chronic condition. Conditions like COPD, Interstitial Lung Disease (ILD), or Adult-Onset Asthma often start with subtle respiratory issues.
- Do you get “bronchitis” every winter?
- Do you get breathless climbing one flight of stairs?
- Do you have a “smoker’s cough” even if you don’t smoke?These are not allergies. These are signs of progressive respiratory diseases. Early diagnosis by a specialist is the only way to prevent long-term lung damage and the risk of respiratory failure later in life.
Preventing Respiratory Issues This Season
Prevention is always better than cure, especially for your lungs.
- Boost Immunity: Eat seasonal fruits rich in Vitamin C (oranges, amla).
- Stay Hydrated: Water keeps the lining of your nose moist, trapping viruses better.
- Hygiene: Wash your hands frequently. Viruses live on doorknobs and phones.
- Vaccination: If you are over 60 or have asthma, ask your respiratory medicine doctor about the Flu and Pneumonia vaccines. They are lifesavers.
Conclusion: Breathe Freely Again
The transition from winter to spring should be about enjoying the weather, not fearing the air. Whether it is a pesky viral Cold or the annual arrival of spring allergies, understanding your body is the first step to recovery.
Don’t let persistent respiratory issues dictate your life. If you are unsure or if your cough just won’t quit, the experts at Eskag Sanjeevani Hospitals are here to help. With the right care, you can navigate this season with healthy lungs and a clear head.
No. This is the biggest difference between allergies and a Cold. Allergies never cause a fever. If you have a raised temperature along with your respiratory issues, it is likely a viral or bacterial infection.
Lying down causes mucus to pool in the back of your throat (post-nasal drip), triggering coughs. Also, cortisol levels (which control inflammation) drop at night, making your airways more sensitive to triggers.
No. The common Cold is caused by a virus. Antibiotics only kill bacteria. Taking them for a viral infection is useless and can increase antibiotic resistance. Only a doctor for respiratory problems can decide if you have a bacterial complication that needs antibiotics.
Look for a specialist (Pulmonologist) with experience in treating both acute infections and chronic respiratory diseases. Eskag Sanjeevani Hospitals hosts a team of senior respiratory specialists equipped with modern diagnostic labs.
Yes. In some people, the same allergens that cause nasal symptoms can eventually trigger lung inflammation. This is known as the “allergic march.” Treating allergies early can help prevent the progression to more serious respiratory issues.
Common tests include a Chest X-ray, Spirometry (to test how much air you can inhale/exhale), blood tests for infection (CBC), and allergy skin prick tests to identify specific triggers for your respiratory issues.
