Seasonal Allergy: What the Calendar Does to a Susceptible Person
If your symptoms arrive with the same month every year, that repetition is the most useful diagnostic information you own.

Seasonal allergy means symptoms that appear at the same point each year, driven by something whose presence in the air follows the calendar. In India this is less about the classical spring pollen season than about the monsoon and the weeks after it, when mould spores and humidity peak, and about post monsoon and winter, when air quality deteriorates. Repetition across years is the strongest clue you can bring to a consultation.
The distinguishing feature of seasonal allergy is that it is boringly predictable. The same weeks, the same symptoms, year after year.
People often apologise for that predictability as though it makes their complaint trivial. It is actually the most valuable thing about it.
The Indian seasonal pattern
Most allergy writing assumes a temperate spring, a defined pollen season and a clear winter. That pattern does not describe most of India, and following advice built on it leads people to look for the wrong trigger at the wrong time.
| Period | What tends to rise |
|---|---|
| Monsoon and immediately after | Mould and fungal spores, indoor damp, dust mite thriving in humidity |
| Post monsoon into winter | Deteriorating air quality, smoke, particulate pollution, temperature swings |
| Spring and dry months | Tree and grass pollen, and considerably more airborne dust |
| Festival periods | Smoke, incense and firecracker particulates, which are often overlooked as triggers |
| Crop burning seasons | A major and well documented contributor to air quality in parts of north India |
Notice how many of these are not pollen. Somebody assuming their annual autumn symptoms are hay fever may in fact be reacting to air quality and mould, which are managed differently.
The diary that is worth keeping
This costs nothing, takes seconds a day, and is more useful over two years than almost any test.
- Date symptoms start each year, and the date they settle.
- Which symptoms dominate. Sneezing runs, blocked nose, itchy eyes, cough, wheeze.
- Where you were. Whether it changes when you travel, and in which direction.
- Indoors or outdoors. Whether being inside helps or worsens it, which separates indoor from outdoor triggers.
- The weather. Windy days, the first rain after a dry spell, humid still days.
- What you took and whether it helped.
After two seasons a pattern emerges that is genuinely actionable, and it usually surprises people. The trigger is often not what they had assumed for years.
Practical measures during your season
None of these are dramatic and together they reduce the dose meaningfully.
- Keep windows shut during the worst hours, typically early morning and evening for pollen, and rely on filtered air or a fan instead.
- Change clothes and rinse your face and hair on getting home, since you carry the trigger indoors with you and then sleep in it.
- Dry washing indoors during your season if pollen is your trigger, which reverses the usual advice for mite allergy.
- Nasal saline rinsing at the end of the day, which physically removes what you have collected.
- Sunglasses outdoors, which genuinely reduces eye symptoms.
- Deal with indoor damp before the monsoon, not during it.
Constitutional case taking asks why this person reacts to a season that everyone else lives through unremarkably.
Seasonal allergy is predictable and irritating. These features are neither.
- Wheezing, chest tightness or breathlessness at any point in the season.
- Waking at night breathless or coughing repeatedly.
- Sudden swelling of lips, tongue or throat, which is an emergency.
- Fever with facial pain and coloured discharge for more than ten days, suggesting infection.
- One sided nasal blockage or bleeding, which is not allergy.
- Symptoms that no longer settle when the season ends.
- Eye pain, visual change, or severe eye swelling rather than simple itch and watering.
When it stops being seasonal
A pattern worth recognising is symptoms that used to be strictly seasonal and now rumble along all year with seasonal peaks. That usually means a second, perennial trigger has been added, most often indoor dust mite or mould, on top of the original seasonal one.
It matters because the management differs. The seasonal part is handled by timing and outdoor exposure, and the perennial part is handled at home, mostly in the bedroom.
That is covered in the blog on dust allergy in an Indian home.
Where classical homoeopathy is interested
In the person, and specifically in the fact that a whole city breathes the same air and a minority of people react to it. That is the observation the constitutional approach is built around.
Case taking asks when the reactivity began, whether it followed a particular illness or period of life, what else the person carries, particularly skin and chest, how they were as a child, and how they are in themselves. Somebody who reacts to a season is a person with a susceptibility that the season reveals, rather than a person who has caught something from the weather.
The remedy is selected for that picture, so none is named here. What can honestly be offered is a change in the pattern, meaning a shorter season, milder symptoms, and less medication needed to get through it.
Not immunity to the season, and not a reason to stop anything prescribed.
The allergies page covers the wider approach, and if you are unsure whether what you have is allergy at all, the blog on rhinitis versus a cold is the place to start.
Common questions
Is seasonal allergy in India the same as hay fever?
Not really. The classical temperate pattern of a spring pollen season describes India poorly. Here the bigger drivers are usually monsoon and post monsoon mould and humidity, and the deterioration in air quality through winter. Someone assuming their autumn symptoms are hay fever may be reacting to something managed quite differently.
How do I work out what my seasonal trigger is?
Keep a simple diary across two years recording when symptoms start and stop, which symptoms dominate, whether being indoors helps or worsens things, and what the weather was doing. That is more useful than most tests, and the answer often surprises people who had assumed a cause for years.
Should I start treatment before my season begins?
For a predictable season, yes, usually a couple of weeks before your usual start date, because it is far easier to prevent inflammation building than to settle it once established. Discuss the timing with whoever prescribes for you rather than adjusting anything yourself.
Why has my seasonal allergy become year round?
Usually because a second, perennial trigger has been added on top of the seasonal one, most often indoor dust mite or mould. That matters because the two are managed differently: the seasonal part by timing and outdoor exposure, the perennial part at home and mostly in the bedroom.
Can homoeopathy help seasonal allergy?
Classical homoeopathy is interested in why a minority of people react to air that a whole city breathes, which is a question about susceptibility. Realistic aims are a shorter season, milder symptoms and less medication needed to get through it, rather than immunity, and nothing prescribed should be stopped.
