Asthma: triggers, symptoms and long-term control

Asthma is a pattern, not an event — a set of triggers, warning signs that arrive days before the attack, and a maintenance dose that keeps the airway quiet.

Most people come to us with the same question in different words: why does this happen every winter, or every time I catch a cold, or only at night. The answer is almost always a specific combination of exposure, airway sensitivity and a treatment that was stopped too early. This article is about finding your own combination.

What the airway is actually doing

• Two things happen at once. The lining of the breathing tubes swells and makes thicker mucus, and the muscle around them tightens. The first is inflammation, the second is spasm.
• A reliever inhaler opens the spasm within minutes and does nothing about the swelling. That is why a good hour can be followed by a bad week.
• The swelling is what makes the airway oversensitive. Once it is there, small things — cold air, a strong smell, laughing — set off what a calm airway would ignore.
• Untreated, the swelling leaves a mark. Years of attacks thicken the airway wall and the peak capacity slips down. Control is not comfort; it is protection.

The trigger map

• Indoor allergens: dust mite in the mattress and pillows, cockroach residue in the kitchen, mould in a damp wall or bathroom ceiling, pet dander on the sofa and the bed.
• Irritants rather than allergens: agarbatti and diya smoke, mosquito coils, cleaning sprays, strong perfume, smoke from someone else's cigarette, traffic fumes at the roadside window.
• Weather and air: the first cold fortnight of winter, sudden temperature change, high humidity, a dust storm, an air-conditioned room that is never cleaned.
• Body factors: a viral cold is the single most common trigger for a week of worse symptoms; acid reflux at night; exercise in cold air; some painkillers and blood pressure tablets in a minority of people.
• Emotional load: fear, anger and breathless talking can set off spasm in an already inflamed airway. This is real, and it is not the cause.
• Keep a two-week note of symptoms with the time of day, the room you were in and what you had done in the hour before. Most people find two or three patterns that they had never connected.

The three symptom patterns

• Occasional: daytime symptoms less than twice a week, nights free, no limits on walking or work. This still needs a written plan even if no daily medicine.
• Not controlled: symptoms most days, night waking, the reliever going through a canister, exercise given up because of breathlessness.
• Severe or unstable: breathlessness while speaking, a reliever that stops working, repeated courses of steroid tablets, any blue-lip or faint episode. This is same-day care, not a home remedy.

What control actually means

• No night symptoms, daytime symptoms no more than twice a week, reliever use no more than twice a week, no limit on walking, stairs or a full day's work, and no attack that needs tablets or a clinic visit.
• Control is measured, not felt. A peak flow meter costs very little and gives a number you can compare across weeks; spirometry at a clinic gives the honest baseline.
• A common mistake is judging asthma by how you feel on a good day. The airway can be quietly inflamed for weeks before symptoms return.

The written plan

• Green zone: the daily preventer, taken even when you feel well, plus the reliever for occasional tightness.
• Yellow zone: night cough, more reliever than usual, a cold that has started to bite — the step up that is decided in advance, not improvised at midnight.
• Red zone: breathless after a few words, reliever not holding for an hour, numbers falling — leave for care now.
• Ask for the plan on paper, with your own numbers on it. A plan nobody has written down is a plan nobody follows in a panic.
• Review every three months while things are moving, and once a year when they are not. Three steady months is when a dose is stepped down, by the doctor who set it.

Where Ayurveda honestly fits

• What helps: a daily routine of slow breathing practice, warm steam in the morning, tulsi and haldi in milk, an early dinner, keeping the sleeping room free of dust and soft toys, and covering the mouth and nose in the first cold week.
• What these do is lower the load on an oversensitive airway. They do not replace the preventer, and anyone who says they do is selling something.
• What is not true: curing asthma in a fixed course, clearing the lungs with a detox, or an unlabelled capsule that works fast — fast relief from an unknown powder is usually a hidden steroid or a hidden bronchodilator.
• Intensive cleansing programmes are not offered here, and in asthma they carry more risk than benefit.

When to be seen

• Book an assessment if you wake at night coughing, if the reliever is used more than twice a week, or if you have cut down exercise to avoid breathlessness.
• Get seen the same day for breathlessness that does not settle with the reliever, for speech broken by breath, or after any episode where the lips or nails looked grey.
• Children who cannot keep up in games, who cough after laughing or running, or who are diagnosed again every winter, need a lung function check and a written plan rather than another syrup.

At our two centres

• Model Town and Burari, first consultation free. We take the history properly, check inhaler technique, do spirometry or peak flow, look at the sleeping room and the work exposure, and write the plan with you.
• We do not stop or swap the medicine your doctor has prescribed. What we change is the trigger load, the routine, the breathing practice and the follow-up — the parts that decide whether the airway stays calm through the season.

The house, room by room

• Bedroom first, because you spend a third of the night there: encase the mattress and pillows, wash bedding weekly in warm water, keep soft toys and stacked clothes out, and let sunlight in for an hour.
• Bathroom and kitchen: a damp wall or black grout is mould, and mould in the bedroom wall matters more than any syrup. Fix the leak, ventilate while cooking, and do not dry clothes on the chair you sleep beside.
• Living room: the source of the smell is the source of the problem — agarbatti, mosquito coils, room fresheners, strong cleaning sprays. A damp cloth and an open window do the same job without the burn.
• Windows facing a road: keep the roadside window shut through traffic peaks and ventilate early morning or late evening instead.
• Change one thing a month and watch the two-week note. A house changed all at once teaches you nothing about which change worked.

Work, travel and the calendar

• Occupational asthma hides in plain sight: flour dust in a bakery, paint and thinners, welding fumes, sawdust, salon chemicals, cleaning in an old building. Symptoms better on a holiday and worse by Wednesday point here.
• Travel: reliever in the bag and not the boot, the written plan photographed on the phone, and the medicine name rather than the brand when buying in another city.
• Cold air is a trigger, not a curse. Cover nose and mouth with a scarf, breathe in through the nose, and warm up for ten minutes before any winter exercise.
• A viral cold is the commonest reason a stable person has a bad fortnight. Start the yellow-zone step on day one rather than waiting for the chest to tighten.

Reflux, weight, sleep and the nose

• Night-time asthma is often a nose-and-stomach problem as much as a lung problem. A blocked nose forces mouth breathing, and acid coming up after a late dinner irritates the airway overnight.
• Dinner three hours before bed, an early hour, and the head of the bed raised a little — this is treatment, not a lifestyle lecture.
• Sinus disease and asthma travel together: facial pressure, thick discharge, reduced smell and night cough usually mean the nose needs treating as well.
• Weight: a modest reduction improves breathlessness and lowers the dose needed to hold control. Slow, steady, with walking as the exercise rather than running.
• Smoking, including someone else's, and vaping: no inhaler works properly in that airway. This is the conversation where honesty matters more than politeness.

Every individual is different. Before starting any new remedy or routine, please check with your treating doctor, especially if you are already on inhalers or steroid tablets.
