| “Every April, my OPD at Pulmovista Clinics doubles. Walk-ins spike. My phone lines are busier. And the reason is always the same — Delhi’s summer and dust storm season has arrived, and patients who were managing reasonably well just weeks ago are suddenly struggling to breathe. After 13 years of treating asthma in this city, I have learned that this surge is entirely predictable — and almost entirely preventable. Here is my personal survival guide for asthma patients in Delhi during summer and dust storm season.” — Dr. Dixit Kumar Thakur |
I am Dr. Dixit Kumar Thakur, Senior Pulmonologist at Pulmovista Clinics, Delhi. I have spent over 13 years treating asthma in one of the world’s most polluted and allergen-rich cities. In that time, I have seen every season create its own wave of exacerbations — but none more predictable, and none more preventable, than the surge I see every April and May when Delhi’s summer heat and dust storm season collide.
In this guide, I am writing directly to you — my patient, or someone who wants to become my patient at Pulmovista Clinics — with everything I know about surviving Delhi’s most challenging asthma season. This is not a generic article. It is the same advice I give in my consultation room, written down so you can refer to it, share it with your family, and use it to stay out of the emergency department this season.
If you take nothing else from this guide, take this: the best asthma treatment in Delhi during summer and dust storm season is not the one you use after an attack. It is the one you put in place before the season begins. Let me show you exactly how.
1. What I See Every April: Why Delhi Summer Doubles My OPD
Let me give you a picture of what April looks like at Pulmovista Clinics. The first week of April is usually normal — winter has ended, pollution from inversions has reduced, and most of my patients who managed well through February and March are feeling relatively stable. Then, around the second or third week of April, something shifts.
The temperatures climb past 38–40°C. The westerly winds start carrying the first fine dust from Rajasthan. The Prosopis juliflora trees — the invasive mesquite that lines Delhi’s roads and parks — are in full pollination. Ozone peaks in the afternoons as strong sunlight drives photochemical reactions. And then the first andhi hits — a wall of dust, silica, pollen, and fungal spores moving at 40–60 km/hour through the city.
Within 48 hours of that first major dust storm, my OPD is full. Walk-in emergencies double. Patients who ran out of their inhalers because ‘everything was fine’ arrive breathless. Parents bring children who were playing outdoors when the storm struck. Adults who refused to wear masks because ‘it looked fine outside’ are now on nebulisers.
This is the pattern I have watched repeat, without exception, for 13 years. And the patients who avoid this pattern are always — without exception — the ones who came to Pulmovista Clinics in March for a pre-season review and followed the plan we made together.
| 🌪 Dr. Dixit Kumar Thakur’s April–May OPD Data at Pulmovista Clinics • Asthma-related OPD visits: approximately 2× higher in April–May vs. January–February • Emergency walk-ins with severe exacerbations: peak in the 24–72 hours following major andhi events • Most common presentation: patients on SABA-only therapy with no anti-inflammatory cover • Most common avoidable cause: patients who stopped their controller inhaler when symptoms improved in March • Most prepared patients: those who attended the Pulmovista pre-season review in March — significantly fewer emergency presentations in this group |
2. Understanding the Enemy: What Delhi Summer and Dust Storms Actually Do to Your Airways
As a pulmonologist, I need my patients to understand what is happening inside their lungs during a dust storm — not because the science is interesting (though it is), but because understanding the mechanism is what makes the right prevention strategy make sense.
The Assault on Your Airways: Layer by Layer
When a major andhi hits Delhi, your airways are facing a simultaneous assault from multiple directions at once:
| What Enters Your Airways | What It Does to Asthmatic Lungs |
| Silica particles (from desert sand) | Directly irritates bronchial mucosa — triggers immediate airway hyper-reactivity within minutes; damages cilia lining airways |
| PM2.5 (fine particulate matter) | Penetrates deep into bronchioles and alveoli — drives eosinophilic and neutrophilic inflammation simultaneously |
| Prosopis / grass pollen grains | Triggers IgE-mediated allergic response in sensitised patients — mast cell degranulation, histamine release, bronchoconstriction |
| Fungal spores (Cladosporium, Alternaria) | Potent aeroallergens — particularly dangerous for patients with mould sensitisation; can cause severe late-phase reactions |
| Endotoxins (bacterial LPS from soil) | Activates innate immune system — drives steroid-resistant neutrophilic airway inflammation |
| Ozone (peaks on hot, sunny post-storm days) | Independently causes bronchospasm — adds to the inflammatory burden, particularly in afternoons following storm events |
| Heat (40°C+ summer temperatures) | Hot, dry air causes evaporative loss from airway surface — triggers thermal bronchospasm, worsens mucus viscosity |
What makes Delhi’s summer dust storms uniquely dangerous — and different from winter pollution events — is this simultaneous multi-trigger exposure. In winter, the primary driver is PM2.5. In summer dust storms, you are dealing with silica, PM2.5, pollen, fungal spores, endotoxins, ozone, and heat — all at once. No single rescue puff was designed to address all of these simultaneously. This is exactly why SMART therapy, which delivers anti-inflammatory treatment with every rescue puff, outperforms traditional SABA-only rescue during dust storm events.
The Biphasic Response: Why You Must Not Trust ‘Feeling Better’ After a Storm
One of the most dangerous patterns I see at Pulmovista is what I call the ‘false recovery’ — a patient has a dust storm exposure, takes a few rescue puffs, feels better, and goes to bed. Then at 2am or 3am they wake up unable to breathe — sometimes severely enough to need emergency admission.
This happens because asthma attacks triggered by allergen exposure — including pollen and fungal spores in dust storms — are biphasic. The immediate response (bronchospasm within minutes) responds to rescue bronchodilators. But 4–8 hours later, a second, often more severe wave of inflammation — driven by eosinophil and T-cell recruitment to the airways — peaks. If you have not suppressed this late-phase response with anti-inflammatory treatment, it can be life-threatening.
| ⚠ Dr. Dixit Kumar Thakur’s Night Safety Rule for Dust Storm Days After any significant dust storm exposure — even if you feel fine with rescue medication — DO NOT go to sleep without first confirming that your asthma is genuinely under control, not just temporarily relieved. Signs that you are NOT safe to sleep without further review: you needed more than 4 rescue puffs during the storm; you can still hear any wheeze at rest; your breathing feels ‘tight’ even without exertion; your peak flow is below 80% of your personal best. If any of these apply — contact Pulmovista Clinics immediately or go to the nearest emergency department. The late-phase response peaks between midnight and 4am. Do not let it catch you asleep. |
3. Dr. Dixit Kumar Thakur’s Pre-Season Checklist: What I Tell Every Pulmovista Patient in March
Every year in March, I run what I call pre-season clinics at Pulmovista. These are focused, structured appointments specifically designed to get my asthma patients ready before andhi season arrives. Here is the exact checklist I go through with every patient:
1. Spirometry check: I measure your current FEV₁ and compare it to your personal baseline. If your lung function has drifted down since your last review — even if you feel ‘okay’ — it means your airways are more inflamed than you realise, and summer will be harder. This is the most important test because it catches silent deterioration before symptoms appear.
2. FeNO measurement: A 10-second breath test that tells me exactly how much eosinophilic inflammation is present in your airways right now. If your FeNO is elevated going into summer, I know you need a higher ICS dose before the pollen season peaks — not after your first exacerbation.
3. Allergy panel review: If you have not had allergy testing recently, March is the time. Knowing which specific pollens and moulds drive your asthma means we can time your antihistamines, intranasal steroids, and — for eligible patients — start the pre-season allergen immunotherapy schedule.
4. Medication optimisation: I review every medication — confirm you are on SMART therapy (not SABA-only), check your inhaler device is correct for your age and coordination, ensure your intranasal steroid is being used daily, and prescribe an oral antihistamine and — where appropriate — an oral steroid standby prescription for severe exacerbations.
5. Inhaler technique re-check: Stress degrades inhaler technique. Patients who used their inhaler perfectly in January often develop subtle errors by March — a slightly wrong inhalation speed, skipping the mouth rinse, not holding the breath long enough. I check every patient’s technique at the pre-season visit because a 30-second correction can prevent a 3-day hospitalisation.
6. Written Dust Storm Asthma Action Plan: Every Pulmovista patient leaves their March appointment with a personalised, colour-coded written action plan specifically designed for dust storm and summer heat events. This tells you — in clear, simple language — exactly what to do when a storm hits, when to step up medication, when to take your steroid standby, and when to call us or go to the emergency department.
7. Biologic therapy assessment: For patients who had 2 or more severe exacerbations in the previous summer or winter — I initiate a biologic therapy eligibility assessment during the March pre-season clinic. The goal is to have biologic therapy in place before summer peaks, not after another hospitalisation forces the issue.

4. My Personal Prescription: The Best Asthma Treatment in Delhi During Summer Season
Patients often ask me: ‘Dr. Thakur, what is the single best thing I can do for my asthma during Delhi’s summer?’ My answer is always the same: there is no single best thing. The best asthma treatment in Delhi during summer and dust storm season is a layered strategy — medications, environment, monitoring, and an emergency plan working together. Let me break each layer down exactly as I explain it to my Pulmovista patients.
Layer 1: Get Your Medications Right BEFORE the Season
The most common mistake I see every April is patients who are on the wrong medication — or the right medication used the wrong way. Here is my summer medication protocol for Pulmovista patients:
| Medication Category | Dr. Dixit Kumar Thakur’s Recommendation for Summer Season |
| Controller inhaler | SMART therapy (ICS-formoterol) is non-negotiable. If you are still on SABA-only rescue, this is the most urgent change to make before summer. Every rescue puff during a dust storm should also be delivering anti-inflammatory medication. |
| Intranasal corticosteroid | Use daily throughout March to June — not just on symptomatic days. Nasal inflammation from pollen and dust directly worsens lower airway asthma through the unified airway. Consistent nasal treatment is non-negotiable during summer. |
| Non-sedating antihistamine | Start in March, before pollen counts peak. Loratadine (10mg once daily) or Fexofenadine (120mg once daily) are my preferred options — no drowsiness, taken once a day. Do not wait for symptoms to start taking it. |
| Oral steroid standby | For patients with a history of severe exacerbations, I prescribe a written standby prescription for Prednisolone 40mg for 5 days — to be started at a clearly defined trigger point in their action plan. This empowers patients to act immediately without waiting for a clinic appointment during a severe event. |
| Leukotriene receptor antagonist (Montelukast) | I add Montelukast for patients with comorbid allergic rhinitis or exercise-induced bronchoconstriction — particularly useful during summer season when both conditions worsen. |
| Biologic therapy (eligible patients) | For severe allergic asthma patients — Omalizumab is my preferred summer season biologic. It blocks IgE, reducing the immediate allergic response to pollen and mould in dust storms. Patients on Omalizumab consistently have better summer seasons than those managed with conventional therapy alone. |
Layer 2: Environment — My Home and Outdoor Protocol
Medication alone is not enough during dust storm season. Environmental control is a clinical intervention — not optional lifestyle advice. Here is exactly what I tell every Pulmovista patient to do:
• HEPA air purifier in the bedroom: This is the single most impactful environmental intervention. Run it on high during dust storm season — especially at night. Check and clean the filter before April.
• N95 mask — always accessible: Keep N95 masks at home, in the car, in your bag, and at the office. A dust storm can develop within 60 minutes during April and May in Delhi — you will not have time to go home and get one.
• Weather and AQI monitoring: Check the SAFAR-Air app and IMD forecast every morning during dust storm season. A ‘strong surface winds’ warning in April or May is a dust storm warning for asthma patients. Prepare accordingly.
• Windows closed — always during and after storms: Do not open windows for at least 90 minutes after a storm passes. PM2.5 remains suspended at dangerous concentrations long after visibility improves.
• Car air conditioning on recirculate: During dust storms and high-AQI days, switch your car AC to internal recirculation mode. Driving through a dust storm with external air intake is equivalent to removing your mask.
• Shower and change clothes after outdoor exposure: Pollen and dust particles settle on hair and clothing. Showering after outdoor exposure on high-pollen, high-dust days significantly reduces the total allergen load you bring indoors.
Layer 3: Monitoring — Know Your Numbers
One thing I emphasise with every Pulmovista patient is that feelings are an unreliable guide to asthma control — especially during dust storm season, when the late-phase response can make you feel fine while your airways are becoming progressively more inflamed. Objective monitoring is essential:
• Peak flow meter: Every asthma patient I see at Pulmovista Clinics receives a peak flow meter and personalised green/yellow/red zone targets. Measure every morning during dust storm season. A reading in the yellow zone means step up therapy that day — before you feel worse. A reading in the red zone means immediate action as per your written plan.
• Rescue inhaler use log: Count how many rescue puffs you use each day during dust storm season. More than 4 puffs in a day is a yellow flag. More than 8 puffs is a red flag requiring urgent Pulmovista review. I ask every Pulmovista patient to keep a simple daily log during April and May.
• Symptom diary: Note morning symptoms, night waking, and exercise limitation each day. A pattern of worsening over 3 consecutive days — even if each day feels ‘manageable’ — is a signal to contact Pulmovista before a crisis develops.
5. The Summer Asthma Triggers I See Most Frequently at Pulmovista: A Clinical Guide
After 13 years of treating Delhi’s asthma patients through summer, I have a very clear picture of which specific triggers cause the most presentations at Pulmovista Clinics between April and June. Here is my clinical guide to each one:
Trigger 1: The Andhi (Dust Storm) — The Biggest Single Event Trigger
Nothing in Delhi’s asthma calendar creates a sharper, faster surge in presentations than a major andhi. Within 24–48 hours of a significant dust storm, my Pulmovista walk-in numbers double or triple. The critical management points I emphasise for andhi events are: go indoors immediately, take pre-emptive rescue puffs at the first sign of tightening (do not wait for full bronchospasm), continue monitoring through the night for the late-phase response, and contact Pulmovista if you used more than 4 puffs.
Trigger 2: Prosopis Juliflora (Mesquite) Pollen — Delhi’s Most Underestimated Allergen
Prosopis juliflora — the invasive mesquite tree that lines hundreds of kilometres of Delhi’s roads, parks, and railway tracks — is the most underestimated major allergen in this city. It pollinates from February through May, with a peak in April, and produces enormous quantities of highly allergenic pollen. Many of my Pulmovista patients have never been tested for Prosopis sensitivity — yet when I add it to their allergy panel, a significant proportion show strong positive reactions.
If your asthma is consistently worst in April and May — particularly when you are outdoors near trees or roads — Prosopis sensitisation should be evaluated. I test for it as part of the standard Pulmovista spring allergy panel, and for confirmed Prosopis-sensitised patients, allergen immunotherapy is available.
Trigger 3: Ozone — The Invisible Afternoon Threat
Ozone is the most underappreciated summer asthma trigger in Delhi. During April–June, intense solar radiation drives photochemical reactions between vehicle exhaust NOx and volatile organic compounds, producing ground-level ozone that peaks between 12pm and 6pm. Unlike PM2.5 — which is highest in the morning — ozone is an afternoon threat. My Pulmovista patients with ozone-sensitive asthma learn to time their outdoor activities for early morning (before 9am) during summer, and to take their SMART rescue puff before any unavoidable afternoon outdoor activity.
Trigger 4: Heat and Dehydration — The Silent Amplifier
Delhi’s summer temperatures — regularly exceeding 42–44°C in May and June — affect asthma through multiple mechanisms that are not always obvious to patients. Hot, dry air causes rapid evaporation from the airway surface, leading to airway cooling and increased osmolarity — both of which trigger bronchospasm. Dehydration makes airway mucus thicker and harder to clear. Heat stress activates systemic inflammatory pathways. And the instinct to move rapidly between extreme outdoor heat and heavily air-conditioned interiors creates repeated thermal bronchospasm triggers throughout the day.
My advice to Pulmovista patients for heat management: stay hydrated (2–3 litres of water daily during summer); transition gradually between hot and cold environments where possible; and carry your rescue inhaler even on days when you feel fine — heat-triggered bronchospasm can strike suddenly.
Trigger 5: Summer Thunderstorm Asthma — A Serious and Under-Recognised Risk
Thunderstorm asthma is a well-documented, potentially life-threatening phenomenon that occurs when pre-monsoon thunderstorms rupture pollen grains already suspended in the air — releasing sub-pollen particles that are small enough to penetrate deep into the lower airways. Unlike intact pollen grains — which are largely filtered by the nose — these sub-pollen particles bypass nasal defences completely.
I see thunderstorm asthma cases at Pulmovista every pre-monsoon season. Patients describe being outside just before a thunderstorm — enjoying the cooling breeze — and then developing sudden, severe bronchospasm within 15–30 minutes. This can be fatal. My instructions to all Pulmovista patients during pre-monsoon season: come INDOORS at the first sign of approaching thunderstorms, particularly if pollen counts are high that day.
6. My Emergency Protocol: What to Do During a Severe Summer Asthma Attack
I give every Pulmovista patient a written emergency protocol — but I also want to share it here, because an asthma emergency is not the time to search for information. Print this, save it on your phone, and make sure your family knows it too.
| 📋 Dr. Dixit Kumar Thakur’s Emergency Protocol for Severe Summer Asthma Attack STEP 1: Sit upright. Do not lie down. Remove yourself from the trigger environment immediately — indoors, windows shut. STEP 2: Take 4 puffs of your SMART rescue inhaler (ICS-formoterol) immediately — one puff every 30–60 seconds. If using a SABA (Salbutamol), take 4 puffs via spacer. STEP 3: Wait 15–20 minutes. Assess response. If significantly improved and staying improved — continue monitoring. Monitor through the night for late-phase response. STEP 4: If partial or no response after 4 puffs — take 4 more puffs (total 8 puffs). Start oral prednisolone standby if prescribed. Contact Pulmovista Clinics immediately. STEP 5: If any of the following — CALL AN AMBULANCE IMMEDIATELY: • Unable to speak in full sentences • Lips or fingernails turning blue (cyanosis) • No improvement after 8 rescue puffs • Confusion, drowsiness, or extreme exhaustion • Peak flow below 50% of personal best PULMOVISTA CLINICS EMERGENCY CONTACT: www.pulmovista.com |
7. Special Groups: My Advice for Children, Elderly Patients, and Outdoor Workers
Children with Asthma During Delhi Summer
Children are my most urgent concern during dust storm season. They have faster respiratory rates, narrower airways, and a strong instinct to play outdoors even when a storm is building. At Pulmovista Clinics, I see a significant spike in paediatric asthma presentations in April and May every year.
| 🩺 Dr. Dixit Kumar Thakur’s Summer Protocol for Parents of Asthmatic Children • Bring your child to Pulmovista Clinics for a pre-season review in March — spirometry and allergy testing adapted for paediatric patients • Provide the school with an updated copy of your child’s Pulmovista Asthma Action Plan — specifically covering dust storm events • Ensure a spare inhaler with spacer is kept at school — accessible immediately, not locked away • Sign up for IMD dust storm alerts on your phone — dust storms in Delhi can develop within 60–90 minutes • Children must come indoors immediately at the first dust storm warning — this overrides all outdoor activity, sports events, or play • Monitor through the night after any dust storm exposure — the late-phase response often peaks at 2–4am in children • After any hospitalisation or severe attack — book an urgent review at Pulmovista within one week for a formal step-up assessment |
Elderly Asthma Patients During Summer
Elderly patients face compound risks during Delhi’s summer — reduced respiratory reserve, frequent cardiac or metabolic comorbidities, and a higher likelihood of being on medications that interact with asthma triggers (beta-blockers, NSAIDs). At Pulmovista Clinics, I pay particular attention to heat stress in elderly asthmatic patients, as dehydration from Delhi’s summer temperatures can concentrate airway secretions and significantly worsen mucus clearance. I advise all elderly Pulmovista patients to keep indoor temperatures between 24–26°C during summer (not aggressively cold, which triggers thermal bronchospasm) and to maintain fluid intake even when not thirsty.
Outdoor Workers — Delhi’s Most Exposed Group
Construction workers, traffic police, street vendors, auto-rickshaw drivers, and delivery workers represent a large and largely unserved population of asthmatic Delhiites who have no choice but to work outdoors during dust storm season. I see patients from these occupational groups at Pulmovista Clinics regularly. My practical protocol for this group: N95 mask mandatory during working hours from April through June; SMART rescue inhaler accessible at all times (not left at home); inform employer of asthma status; and a standing agreement that they will come to Pulmovista on the same day as any significant exacerbation — not the following week.
8. Why Patients Across Delhi Choose Pulmovista Clinics for the Best Asthma Treatment in Delhi
Over 13 years, I have built Pulmovista Clinics into what I believe is genuinely the best asthma treatment in Delhi for patients who want more than a prescription — patients who want a specialist who understands this city, its seasons, its pollution, and its allergens, and who builds a management plan around all of those realities.
Here is what distinguishes care at Pulmovista Clinics from what is available at most general practice settings in Delhi:
1. Hyperlocal seasonal expertise: I have been treating Delhi asthma patients through 13 consecutive summer and dust storm seasons. I know exactly which weeks are highest risk, which weather patterns precede the worst storms, and which allergens peak when. This hyperlocal expertise directly informs every Pulmovista seasonal asthma management plan.
2. Complete on-site diagnostics: Spirometry, FeNO measurement, full allergy panel testing (including Prosopis, Alternaria, and other Delhi-specific allergens that many clinics do not test for), and established relationships with premier radiology, sleep study, and pathology partners.
3. GINA 2026 compliant prescribing: Every prescription at Pulmovista is reviewed against current GINA guidelines. No patient leaves my clinic on SABA-only therapy. Every eligible patient is offered SMART therapy, and every severe asthma patient is assessed for biologic therapy.
4. All five biologic therapies: Pulmovista Clinics can assess, prescribe, and monitor Omalizumab, Mepolizumab, Benralizumab, Dupilumab, and Tezepelumab — giving every severe asthma patient access to the full range of GINA Step 5 treatments.
5. Allergen immunotherapy: For patients with confirmed allergic sensitisation — particularly to Delhi-specific allergens including Prosopis pollen, dust mites, and Aspergillus mould — Pulmovista offers both subcutaneous and sublingual immunotherapy to modify the underlying allergic disease.
6. Urgent summer access: During April–June, I reserve dedicated urgent slots at Pulmovista for patients with dust storm and summer exacerbations. My patients do not spend three days trying to get an appointment while their asthma deteriorates. Same-day or next-day urgent review is available.
7. Teleconsultation during storms: On days when severe dust storm conditions make travel dangerous, teleconsultation with me is available via Pulmovista Clinics. You can have a clinical review, get prescription adjustments, and decide on next steps without leaving home.
8. Written, personalised action plans: Every Pulmovista patient receives a written, colour-coded asthma action plan specifically updated for summer and dust storm season — including personalised peak flow zones, medication step-up instructions, and clear criteria for emergency department referral.
Conclusion: Delhi’s Dust Storm Season Demands Preparation — Pulmovista Clinics Is Here to Help
Delhi’s andhi season is one of the most challenging environmental periods for asthma patients anywhere in India. The combination of silica, PM2.5, peak-season pollens, fungal spores, and ozone creates a multi-trigger onslaught that can overwhelm even well-managed asthma if patients are not prepared. But preparation — the right medication plan, the right environmental controls, the right action plan, and the right specialist in your corner — can make the difference between a difficult season and a dangerous one.
At Pulmovista Clinics, Dr. Dixit Kumar Thakur and the respiratory medicine team are dedicated to ensuring that every Delhi asthma patient enters dust storm season equipped with everything they need: a personalised action plan, optimised SMART therapy, allergy management, and access to advanced treatments including biologic therapy and allergen immunotherapy for those who need them. The best asthma treatment in Delhi during dust storm season is not a single medication — it is a comprehensive, specialist-guided strategy built around your specific phenotype, your specific triggers, and Delhi’s specific environment.

FAQs-Dust Storm Asthma and Best Asthma Treatment in Delhi
- How is dust storm asthma different from regular pollution-triggered asthma in Delhi?Regular pollution-triggered asthma in Delhi is primarily driven by chronic, sustained PM2.5 exposure from vehicle emissions, industrial sources, and biomass burning. Dust storm asthma involves a sudden, massive spike in PM10, silica, and simultaneously elevated biological allergens — particularly pollens and fungal spores. The combination creates a more complex, multi-mechanism attack that often involves both the immediate allergic response and a late-phase inflammatory response 4–8 hours later. At Pulmovista Clinics, Dr. Dixit Kumar Thakur treats the two patterns differently — dust storm events frequently require a step-up in anti-inflammatory therapy beyond what standard pollution management would dictate.
- Should I keep my windows open or closed during a Delhi dust storm?Closed — completely. This is one of the most common mistakes Dr. Dixit Kumar Thakur sees asthma patients make. Many people open windows during a dust storm thinking ventilation will help. In fact, outdoor PM10 during an andhi event can exceed 1,500 µg/m³ — thousands of times higher than indoor air with a HEPA purifier running. Keep all windows and doors shut, run your HEPA air purifier on maximum, and switch your air-conditioner to internal recirculation mode. Do not open windows for at least 60–90 minutes after a storm passes — fine particles remain suspended in outdoor air long after visibility improves.
- My child had a severe asthma attack during a dust storm. What should I do now?Book an appointment at Pulmovista Clinics as soon as possible — within 24–48 hours if the attack was severe, or within one week for a moderate event. Dr. Dixit Kumar Thakur will conduct a post-exacerbation assessment including spirometry and FeNO measurement to evaluate whether the child's baseline control has been affected, whether their treatment plan needs to be stepped up, and whether allergy testing or biologic therapy assessment is indicated. A single severe exacerbation in a child is a red flag that requires specialist review — not a 'wait and see' response.
- Is there a specific best asthma treatment in Delhi for patients who get worse every dust storm season?Yes — and at Pulmovista Clinics, Dr. Dixit Kumar Thakur takes a very structured approach to recurrent seasonal exacerbators. The assessment typically reveals one of three correctable situations: (1) inadequate baseline controller therapy — resolved by stepping up to SMART or optimising SMART dosing; (2) untreated allergic sensitisation to seasonal pollens or moulds — resolved through allergen immunotherapy; or (3) severe allergic asthma with IgE-mediated responses — resolved through biologic therapy with Omalizumab. In each case, the best asthma treatment in Delhi for this patient profile involves a specialist assessment rather than simply increasing the rescue inhaler dose.
- Can I exercise outdoors in Delhi during dust storm season if I have asthma?During active andhi events or on days with AQI above 200 — no. Dr. Dixit Kumar Thakur strongly advises asthma patients against outdoor exercise during dust storm season whenever air quality is poor. Exercise significantly increases ventilation rate and oral breathing, bypassing nasal filtration and delivering far higher doses of dust, pollen, and fine particles to the lower airways. On moderate days (AQI 100–150, no active storm), outdoor exercise early in the morning (before 8am, before ozone peaks and before convective winds strengthen) with an N95 mask is a possible compromise — but discuss this individually with Dr. Thakur at your Pulmovista consultation.
