Important reassurance you can give people

These sources are aligned on three key points:

✔ Mould exposure can worsen asthma, allergies and respiratory illness.

Especially in children, older adults, and people with chronic lung conditions (like ABPA, CPA, bronchiectasis).

✔ Mycotoxins in UK homes are not a common cause of chronic, systemic illness.

Reputable agencies (NHS, UKHSA, WHO) do not support “mycotoxin testing” or expensive “detox” treatments.

✔ Fixing the building is the most important treatment.

Ventilation, reducing humidity, removing contaminated soft furnishings, and remediation are the real interventions.

🌍 Does where you live affect aspergillosis or ABPA?

UK-focused guidance, with additional advice on overseas locations

People with ABPA, CPA, fungal allergy, SAFS or bronchiectasis often wonder whether certain regions — in the UK or abroad — are better or worse for their lungs. The truth is:

⭐ Aspergillus is everywhere worldwide

No country, region or climate is fungus-free.
What matters most is:
the quality of the home + humidity + air quality + healthcare access.

Below is a clear guide.

🇬🇧 UK Locations (summary)

The property matters more than the postcode.
But here is the quick UK overview:

👍 Often easier for lung conditions:

  • South West England (cleaner air, milder climate)

  • Rural East Anglia

  • Parts of Northumberland

  • Coastal areas with modern, well-insulated homes

👀 More challenging for some patients:

  • Older stone houses in wet regions (Scotland west coast, Wales)

  • Inner-city pollution corridors (London, Birmingham, Manchester)

  • Homes near major roads (M25, M6, M1)

✈️ Overseas Locations Potentially Better for Aspergillosis or ABPA

The goal is lower humidity, good air quality, dry housing, and strong healthcare access.

🌞 1. Dry Mediterranean climates (often helpful)

Examples:

  • Southern Spain (Andalusia, Murcia)

  • Portugal (Algarve, Alentejo inland)

  • Southern Italy (Puglia, Sicily in the drier months)

  • Greece (many islands have low humidity outside peak summer)

  • Cyprus (very dry outside Jan–Feb)

Why beneficial:

  • Lower humidity → less indoor mould growth

  • Plenty of ventilation and sunlight

  • Good modern building standards (if choosing newer homes)

Watch out for:

  • Very high summer temperatures

  • Saharan dust events (e.g., in Spain, Cyprus, Greece)

  • Avoid older damp stone buildings

🏜️ 2. Dry, warm desert or semi-desert climates (excellent for humidity control)

Examples:

  • Arizona (USA)

  • New Mexico (USA)

  • Utah (USA)

  • Certain parts of Australia (inland areas with low humidity)

Why beneficial:

  • Very low humidity (mould struggles to grow indoors)

  • Strong sunlight

  • Good ventilation

Watch out for:

  • Wildfire smoke in some regions

  • Dust storms (mainly in the US Southwest)

  • Healthcare insurance considerations (especially in the US)

🌊 3. Mild coastal regions with good air quality

Examples:

  • New Zealand (South Island especially)

  • Canada’s west coast (Vancouver Island outside wildfire season)

  • Northern Spain / Basque Coast (clean air, moderate climate)

Benefits:

  • Clean air

  • Access to high-quality healthcare

  • Good housing standards

Watch out:

  • Wildfire season in Canada

  • Damp winters in some coastal climates

  • Avoid older wooden properties with poor ventilation

🔥 Overseas Locations That May Be More Challenging

🌧️ 1. Extremely humid tropical climates

Examples:

  • Singapore

  • Malaysia

  • Indonesia

  • Thailand

  • Caribbean islands

  • Florida (USA)

  • Queensland (Australia’s tropical belt)

Why problematic:

  • High humidity all year → indoor mould grows very easily

  • Air conditioning constantly needed

  • Outdoor fungal levels very high

  • More airborne allergens overall

🌲 2. Areas with frequent wildfires or smoke seasons

Examples:

  • California

  • British Columbia

  • Eastern Australia

  • Mediterranean wildfire zones (Greece, Spain, Italy in summer)

Smoke exposure is a major trigger for asthma, ABPA and bronchiectasis.

🍃 3. Locations with heavy pollution

Examples:

  • India (Delhi, Kolkata)

  • China (some industrial regions)

  • Eastern Europe (coal-heavy areas)

  • Middle East cities with dust + pollution

Pollution is often a bigger trigger than Aspergillus.

❤️ What matters most: Your home + your lifestyle, not the country

A “safe” home for aspergillosis or ABPA is:

✔️ dry
✔️ modern or well-renovated
✔️ free from mould
✔️ with mechanical ventilation or good airflow
✔️ away from busy roads
✔️ in a low-pollution area
✔️ without damp basements, cellars, old timber, or overgrown foliage touching the house

Regardless of UK or overseas, these matter 10× more than the region.

📌 Summary for Aspergillosis Patients

  • Aspergillus exists everywhere — no location is completely safe or dangerous.

  • Low humidity, good air quality and dry modern housing are the key factors.

  • Mediterranean climates, dry inland regions, and moderate coastal areas can be good choices.

  • Very humid tropical climates are the most challenging.

  • Pollution and wildfires are often bigger risks than fungal spores.

🎄 Why Christmas Decorations Can Trigger Symptoms

An explainer for people living with aspergillosis, asthma, ABPA, CPA and bronchiectasis

Many people with aspergillosis notice a sudden increase in sneezing, coughing, wheezing or chest tightness when unpacking Christmas decorations. This is extremely common and usually caused by environmental triggers, not new infection.

✅ What’s on decorations after a year in storage?

When decorations, artificial trees, or boxes have been stored for months, they often collect:

  • Dust

  • Fungal spores, including Aspergillus

  • Dampness or musty smells

  • Particles from cardboard

  • Fibres from artificial branches

For people with allergic aspergillosis (ABPA), severe asthma or sensitive airways, this sudden exposure can cause an allergic flare or airway irritation.

🎄 Why this affects aspergillosis patients more

  • Airways may already be inflamed or mucus-filled, so irritants cause quicker reactions.

  • People with ABPA or SAFS react strongly to environmental allergens.

  • People with chronic pulmonary aspergillosis (CPA) or bronchiectasis may have reduced clearance, so spores or dust linger longer in the lungs.

This does not usually indicate infection — it’s most often an irritation flare.

🛡️ How to protect yourself next time

A few simple steps make a big difference:

  • Wear a mask (FFP2) when opening boxes or shaking dust off.

  • Take boxes outside, or open near an open window.

  • Wipe decorations with a damp cloth rather than brushing them.

  • Rinse or wipe artificial trees, especially branches.

  • Use sealed plastic containers rather than cardboard for storage.

  • Avoid shaking items indoors, as this scatters spores.

🌬️ If you’ve already had a flare

Most people settle within hours to a few days. You can try:

  • Your usual inhalers (especially preventers).

  • Airway clearance if you normally use it.

  • Saline nebulisers/inhalers, which can soothe irritated airways.

  • Rest, fluids, and avoiding further triggers for a short while.

Seek medical advice if symptoms are unusual for you, don’t settle, or you are already unwell.

💬 The key message

Decorations don’t cause new aspergillus infection — but they can release a burst of irritants and spores that your lungs react to. Taking a few precautions can help you enjoy the season without a flare.

🌲 Why Rough-Cut Wood Arrives Mouldy — and How to Reduce the Risk (Important for Aspergillosis Patients)

For anyone living with aspergillosis, ABPA, bronchiectasis or asthma, mould exposure can trigger symptoms or flares. Recently, several patients have reported that rough-cut timber is arriving mouldy from DIY suppliers, sawmills, or timber merchants.

Here’s why this happens — and what suppliers should be doing to prevent it.

⭐ Why rough-cut wood gets mouldy (especially in the UK)

Mould grows on timber whenever three conditions are present:

  1. Moisture

  2. Poor airflow

  3. Warm or humid air

Rough-cut timber is especially vulnerable because:

  • its uneven surface holds moisture,

  • it is often stacked tightly,

  • it may not be dried properly,

  • and UK weather (rain + high humidity) encourages mould.

Many suppliers wrap wood in plastic, which traps condensation during transport. This can create a humid “greenhouse” around the timber — perfect for mould growth in only 24–48 hours.

⭐ What UK suppliers should be doing (even for low-cost timber)

These are standard industry practices in UK timber yards and sawmills. None of them require wood to be kiln-dried (which is more expensive).

✔ 1. Air-dry properly (“sticker stacking”)

Boards must be stacked with spacers (“stickers”) between them so air can circulate.
No airflow = mould.

✔ 2. Store under cover, not outside in the rain

A simple open-sided shelter is enough.
Rain-soaked timber nearly always grows mould in transit.

✔ 3. Use breathable wrapping — NOT plastic sheeting

Plastic traps moisture.
Breathable paper wrap or perforated cover prevents condensation build-up.

✔ 4. Apply anti-fungal dip (borate)

Most UK sawmills use anti-mould dips to prevent blue-stain and mould during storage.
This costs pennies per board.

✔ 5. Moisture-test before delivery

A good supplier will check wood is below 20–22% moisture before dispatch.
Wet wood + UK weather = guaranteed mould.

⭐ Kiln drying is not essential

Kiln-dried timber is more expensive because it uses energy, equipment, and time to force-dry the wood.

But you do not need kiln-dried timber to avoid mould.

You simply need a supplier who:

  • stores the timber properly,

  • allows airflow,

  • avoids plastic,

  • and checks moisture before delivery.

If rough-cut wood is arriving mouldy, it usually means these steps were not followed.

⭐ What you can do to protect yourself (aspergillosis patients)

If you receive wood that:

  • smells musty,

  • has surface mould,

  • or shows green/black spots,

…it is best not to bring it indoors until cleaned.

✔ Immediately unwrap outdoors

Plastic wrapping traps mould spores.

✔ Keep well away from ventilation intakes, windows, or living areas

This avoids airborne spores entering the home.

✔ If mould is visible — return it

You have the right to reject mouldy timber.

✔ If keeping it, clean outdoors with PPE

Use:

  • gloves

  • FFP3 mask

  • borax solution (borax + hot water)
    to remove early surface mould.

Never sand mould indoors — sanding releases spores.

⭐ Simple Diagram: Correct Way to Store Wood to Prevent Mould

Correct storage includes:

  • boards stacked with spacers between them (“sticker stacked”),

  • raised on bearers above the ground,

  • stored under a roof with airflow on all sides,

  • NEVER wrapped in sealed plastic,

  • ends exposed to allow moisture to escape.

This method is cheap, simple, and prevents mould without needing expensive kiln drying.

⭐ Summary for Aspergillosis Patients

Rough-cut wood should not arrive mouldy.
Mould growth usually means it was:

  • stacked badly,

  • stored wet,

  • wrapped in plastic,

  • or shipped before drying.

For people with aspergillosis, ABPA, bronchiectasis or severe asthma, mould spores can trigger symptoms — so it’s completely reasonable to:

  • refuse mouldy timber,

  • request proper handling,

  • or ask the supplier to follow UK best practice.

🌬️ Breathing Easier: Keeping Your Air Clean at Home, Work and When Travelling

People with lung conditions such as aspergillosis, asthma, or bronchiectasis often find their symptoms worsen in certain environments — especially where the air feels dusty, damp, or polluted.
The good news is that there are simple, practical steps you can take to control your surroundings, reduce flare-ups, and make your home a safer, healthier place to breathe.

🏠 At Home

Keep It Dry and Well-Ventilated

  • Tackle damp and leaks early. Mould thrives in moist places — even hidden behind furniture or under wallpaper.

  • Trust your nose. If something smells damp, it probably is. A musty smell means moisture is trapped somewhere — investigate and dry it before mould can grow.

  • Ventilate daily. Open windows when outdoor air is clean, or use extractor fans in kitchens and bathrooms.

  • Prevent moisture spreading. When showering, cooking, or drying laundry, close doors to other rooms so steam and humidity don’t spread through the house.

    • Run the extractor fan during and for at least 15–20 minutes afterwards, or until humidity drops.

    • Short humidity spikes are normal. It’s common for relative humidity (RH) to rise above 60% during cooking, showering, or drying clothes — what matters is that it returns below 60% quickly once fans or windows are open.

    • If condensation lingers or humidity stays high for more than 30–40 minutes, increase ventilation or use a dehumidifier.

  • Use humidity-sensing extractor fans. These switch on automatically when humidity rises and off when it falls.

    • Choose one with a humidistat and timer, vented directly outdoors (not into a loft or wall cavity).

    • Clean the fan cover and check filters every few months.

  • Dry laundry safely. Use a vented or condenser tumble dryer and empty or clean filters and tanks regularly.

    • Avoid drying clothes on radiators unless you’re using a dehumidifier or have good airflow.

  • Monitor humidity. Use a small digital hygrometer to track RH in different rooms.

    • Aim for 40–60% most of the time — this discourages mould and keeps air comfortable.

    • Above 60% for long periods encourages condensation and spores; below 35% can dry and irritate airways.

  • Use the right size dehumidifier.

    • Check the model’s rated room area (m²) or litres per day extraction rate.

    • A compact unit may cope with a small bedroom or bathroom but not a whole flat or open-plan area.

    • Keep doors closed while it’s running for best results, and empty and clean the water tank regularly to prevent bacterial build-up.

Control Dust and Irritants

  • Vacuum regularly with a HEPA-filtered vacuum cleaner.

  • Use microfibre cloths for dusting rather than dry dusters that stir particles into the air.

  • Avoid strongly fragranced cleaning products, candles, incense, and air fresheners — they release fine particles and chemicals that irritate sensitive lungs.

  • Choose low-VOC (low-odour) paints and furnishings when redecorating.

Keep Air Clean

  • If you live near traffic or building work, keep windows closed during busy times and ventilate later.

  • A room air purifier with a true HEPA filter can remove dust, pollen, and fungal spores effectively.

  • Choose the right size for your room.

    • Check the purifier’s Clean Air Delivery Rate (CADR) or maximum room coverage and ensure it matches or slightly exceeds your room size.

    • A small desktop purifier won’t clean a large living room or bedroom effectively.

    • For open-plan or high-ceiling spaces, you may need more than one unit.

  • Maintain it properly:

    • Replace or clean filters exactly as the manufacturer recommends (usually every 6–12 months).

    • Never wash or vacuum a disposable HEPA filter unless the manual allows it.

    • A clogged or undersized filter won’t clean air effectively and may re-release particles.

🌤️ Knowing When the Outside Air Is Clean — and How to Filter It Indoors

1. Check Air Quality Before Ventilating

It isn’t always obvious when outdoor air is safe to bring inside.
Modern air-quality data helps you choose the best times to open windows or run fans.

How to check:

  • Use free apps such as Air Quality Index (AQI) UK, Breezometer, Plume Labs, or AirVisual.

  • Visit DEFRA’s UK Air Information or check BBC Weather → Air Quality.

  • Look for PM2.5 (fine particles) and NO₂ (traffic pollution) levels — these are key irritants for sensitive lungs.

  • “Good” or “Low” readings mean it’s a good time to ventilate or air rooms.

  • Avoid opening windows near busy roads during rush hour or when pollution alerts are issued.

💡 Tip: Air quality is often better early in the morning or late in the evening when traffic and heat are lower.

2. Filter the Air as It Comes In

If you live near roads, building work, or farmland, you can reduce what enters while keeping ventilation safe:

🪟 Window Vent Filters

  • Many modern trickle vents can take fine mesh or electrostatic filters to trap pollen, dust, and spores.

  • Replace or wash filters regularly — clogged filters restrict airflow.

🌀 Filtered Ventilation Systems

  • MVHR systems (Mechanical Ventilation with Heat Recovery) pull in outdoor air, filter it, and expel stale indoor air — great for energy-efficient or damp-prone homes.

    • They help control humidity and filter pollutants.

    • Filters must be cleaned or replaced every few months.

  • Positive Input Ventilation (PIV) systems bring in filtered air gently from a roof or external vent, improving airflow and reducing condensation.

🧺 DIY Improvements

  • Clip-on intake filters can fit over some wall vents or fan inlets.

  • Use a portable HEPA purifier placed near an open window to “clean” incoming air as it circulates.

  • Keep window ledges, vent grilles, and trickle vents dust-free — they collect spores over time.

3. Balance Fresh Air and Safety

It’s important not to seal up a home completely — stale, humid air encourages mould.
The goal is controlled ventilation:

  • Ventilate when outdoor air is cleanest and driest.

  • Keep extractor fans running during steamy activities.

  • When outdoor air quality is poor, use purifiers and dehumidifiers indoors until it improves.

4. Low-Cost Monitoring at Home

You can buy small indoor/outdoor air-quality monitors that track PM2.5, temperature, and humidity.
These help you:

  • Spot pollution drifting indoors (from traffic, wood smoke, etc.).

  • Choose the best times to ventilate.

  • See how quickly humidity or particles fall after cooking or cleaning.

🌱 Summary

What to Do Why It Helps
Check local air-quality apps before opening windows Avoids letting polluted air inside
Ventilate during low-pollution hours Brings in cleaner, fresher air
Fit filters to vents or use MVHR/PIV systems Reduces dust and spores from incoming air
Clean vents, trickle filters, and window frames regularly Prevents build-up of trapped dust
Use a portable HEPA purifier near open windows Cleans incoming air in real time

🧽 Dealing with Mould and Dust Safely

Even in well-kept homes, mould and dust can build up in damp weather or hidden corners. If you see black or green patches, or notice a musty smell, act promptly — but take care to protect your lungs.

⚠️ Before You Start

  • Protect yourself: wear a well-fitted FFP2 or N95 mask, gloves, and, if possible, eye protection.

  • Avoid dry brushing or vacuuming visible mould — this can spread spores into the air.

  • Keep the area well ventilated but close doors to other rooms so spores don’t travel.

  • If the mould covers more than 1 square metre, keeps returning, or is linked to a leak, ask your landlord or council for professional help.

🧴 Cleaning Small Areas of Mould

  1. Wipe gently — don’t scrape.
    Use disposable cloths or ones you can boil-wash later. Avoid wire brushes.

  2. Use mild cleaning solutions:

    • Mix a few drops of washing-up liquid in warm water, or

    • Use a dilute bleach solution (1 part thin bleach to 9 parts water) on tiles or uPVC — ventilate well and never mix bleach with other cleaners, or

    • Try a specialist anti-fungal cleaner for painted or porous surfaces.

  3. Dry the area thoroughly.
    Use ventilation or a dehumidifier; mould will return if the surface stays damp.

  4. Dispose of cloths and gloves in a sealed bag. Wash hands well afterwards.

🧹 Managing Dust and Allergens

  • Vacuum at least twice weekly with a HEPA-filtered cleaner.

  • Dust with a damp microfibre cloth, not a feather duster.

  • Wash bedding and soft furnishings regularly at 60 °C if the fabric allows.

  • Avoid clutter that collects dust (papers, books, soft toys).

  • Keep humidity within 40–60% and fix damp quickly.

🌱 Preventing Mould and Dust Returning

Action Why It Helps
Find and fix leaks or condensation sources Mould needs moisture to grow
Ventilate kitchens, bathrooms, and drying areas Removes steam before it spreads
Use humidity-sensing fans or dehumidifiers Keeps humidity in a safe range
Maintain a steady indoor temperature Reduces cold surfaces and condensation
Close doors during steamy activities Stops damp air moving into other rooms
Replace or clean HEPA filters regularly Maintains air-cleaning performance
Check behind furniture and on windowsills Finds hidden damp early
Repaint cleaned areas with mould-resistant paint Discourages regrowth

🚫 What Not to Do

  • Don’t paint over mould — it will grow back.

  • Don’t use strong chemicals or foggers in small spaces — they can irritate lungs.

  • Don’t use steam cleaners on large mould patches — they can spread spores.

  • Don’t ignore damp smells — they always mean hidden moisture somewhere.

💼 At Work

  • Ask about ventilation and report any damp, leaks, or condensation.

  • Keep your workspace tidy and free of dust-collecting clutter.

  • If cleaning sprays or perfumes cause coughing, discuss adjustments with your manager or occupational health team.

✈️ When Travelling

  • Check air-quality forecasts before travelling and avoid outdoor activity on high-pollution or pollen days.

  • Choose clean, dry accommodation — avoid musty or damp-smelling rooms.

  • Pack a small hygrometer or travel dehumidifier for longer stays.

  • Use a well-fitted FFP2 or N95 mask in crowded or polluted environments.

  • Stay hydrated and pace activities in humid or hot weather.

🩺 Listen to Your Body

Keep a short diary of when and where your symptoms flare up, along with temperature, humidity, or smells you notice. Patterns often reveal your personal triggers.

🌱 Key Points

Good Practice Why It Matters
Keep home dry, clean, and ventilated Reduces mould and spore exposure
If it smells damp, it probably is Early warning of hidden moisture
Humidity above 60% after showering or cooking is normal — keep it short Prevents condensation and mould
Close doors while cooking, showering, or drying laundry Stops moisture spreading
Use humidity-sensing extractor fans Clears steam automatically
Monitor humidity (40–60%) Keeps air comfortable and discourages spores
Match HEPA filters and dehumidifiers to room size Ensures real air-cleaning and drying effect
Maintain and replace filters regularly Keeps air safe and fresh
Check outside air quality before opening windows Avoids bringing pollution indoors
Filter incoming air with vents or MVHR/PIV systems Keeps dust and spores out
Clean small mould patches safely with mild detergent Removes spores without irritation
Fix leaks, repaint with mould-resistant paint Prevents regrowth
Avoid strong scents and aerosols Reduces airway irritation
Plan travel around clean-air days Lowers risk of flares and infections

💬 Final Thought

You can’t control every environment — but small, steady habits make a big difference.
If something smells damp, it probably is. Deal with it early, clean gently, dry thoroughly, and keep air moving.
Short humidity spikes after showering or cooking are normal — just make sure they don’t linger.
Choose purifiers and dehumidifiers that are the right size for your rooms, and maintain them well.
Check outdoor air quality before airing your home, and use filters to keep what’s good while blocking what’s not.
A dry, clean, well-ventilated home gives your lungs the best chance to stay healthy every day — wherever you are.

🧬 What IgE Is and Why It Matters

IgE is a type of antibody your immune system makes when it reacts to something it sees as harmful — such as pollen, mould, pet dander, or certain foods.
In people with allergic or fungal lung disease, IgE can rise sharply because the body’s immune system is over-reacting.

High IgE isn’t dangerous on its own, but it shows that your immune system is “switched on” and inflamed. The goal is to calm that inflammation and reduce exposure to what’s triggering it — not simply to force the number down.

✅ Best Practices for Reducing IgE Levels

1️⃣ Identify and Avoid Triggers

Reducing exposure is the first and most effective step.

  • Allergens: dust mites, moulds (especially Aspergillus), pollens, pets.

  • Environmental irritants: cigarette smoke, air pollution, strong odours, damp housing.

  • Use HEPA filters, good ventilation, and address damp or mould at home.

  • In ABPA, avoiding heavy exposure to fungal spores (e.g. gardening compost, rotting leaves, renovation dust) is particularly important.

2️⃣ Control Inflammation and Allergic Response

Because IgE is a marker of allergic inflammation, treatment focuses on calming the immune system:

  • Corticosteroids (oral or inhaled) can suppress inflammation and lower IgE over time.

  • Biologic therapies such as:

    • Omalizumab (Xolair) – directly targets IgE and lowers levels in allergic asthma or ABPA.

    • Mepolizumab, Benralizumab, or Dupilumab – reduce eosinophil-driven inflammation and may indirectly lower IgE.

    • Choice depends on your disease type and blood test results.

  • Antifungal therapy (e.g. itraconazole, voriconazole, posaconazole) can help reduce fungal load in ABPA and often leads to gradual IgE reduction as the reaction settles.

3️⃣ Manage Asthma or Lung Disease Well

Stable lungs mean fewer immune flares and less IgE activity:

  • Use prescribed inhalers regularly (preventers, not just relievers).

  • Follow your asthma or CPA action plan.

  • Attend regular reviews with your respiratory team.

  • Report any new symptoms such as increased cough, wheeze, or mucus plugs early.

4️⃣ Support Overall Immune Balance

Simple lifestyle steps can also help keep inflammation low:

  • Eat a balanced diet rich in fruit, vegetables, and omega-3 fats.

  • Sleep well and manage stress (both can worsen inflammation).

  • Avoid smoking or vaping.

  • Keep vaccinations (e.g. flu, COVID, pneumococcal) up to date.

📊 Interpreting IgE Levels

  • IgE levels naturally fluctuate and may take weeks or months to fall after treatment.

  • Doctors often look at the trend (rising or falling) rather than one number.

  • In ABPA, a fall of 35–50 % from baseline after treatment usually shows improvement.

  • It’s also possible to feel better while IgE remains high — so the result must always be interpreted alongside symptoms and scans.

🚫 What Not to Do

  • Don’t chase a “perfect” IgE number — focus on feeling better and reducing inflammation.

  • Don’t stop steroids or antifungals suddenly unless advised by medical doctor, as this can cause a rebound flare.

  • Don’t rely on supplements or “immune boosters” that claim to lower IgE — none are proven to help and some may worsen allergies.

🩺 In Summary

Goal Best Approach
Reduce IgE triggers Avoid mould, dust, smoke, allergens
Calm inflammation Steroids or biologics under medical supervision
Treat underlying disease Antifungals for ABPA/CPA, good asthma control
Support immune balance Healthy lifestyle, good sleep, stress reduction

🌱 Key Message

You can’t “switch off” IgE completely — it’s part of your immune defence.
The aim is to reduce unnecessary immune activation, keep symptoms stable, and prevent lung damage.
With the right mix of trigger avoidance, anti-inflammatory treatment, and regular monitoring, IgE levels usually fall gradually as the condition improves.

When Scents Cause Symptoms: What Patients Say About Odour Triggers

Many people living with asthma, Allergic Bronchopulmonary Aspergillosis (ABPA), or bronchiectasis describe strong reactions to everyday smells — perfumes, cleaning products, paints, or air fresheners.
These reactions can cause immediate coughing, wheezing, throat irritation, or chest tightness, and they can last for hours or even days.

To understand this better, we asked members of our patient community:

“Are there any smells that don’t affect you?”

Their replies were detailed, honest, and very relatable.

💬 What patients told us

“I’m OK with most perfumes, but not Estée Lauder. Aftershaves can be troublesome.”
“Unfragranced alcohol hand sanitiser is fine — even though it smells strong.”
“Cooking smells are OK if it’s food I can eat, but not frying.”
“Crowded rooms full of cleaning products or perfume — that’s when I start coughing.”
“I use peppermint essential oil to mask other smells if I get caught off guard.”
“If I avoid mould, dust, aerosols, and detergents, I can generally stay well.”

These voices show that odour sensitivity varies hugely from person to person — and what’s tolerable one day might trigger symptoms another.

🌸 Smells people can usually tolerate

Even among those highly sensitive to scents, a few odours were commonly reported as “safe”:

  • Some light or natural perfumes

  • Alcohol-based hand sanitisers (if unfragranced)

  • Food smells from meals the person can eat

  • Saline or hypertonic saline nebulisers

  • Outdoors air after rain — described by some as “clear” or “fresh”

Many added that they simply don’t notice safe smells — because their airways stay calm.

🚫 Common odour triggers

Category Examples mentioned by patients
Fragrances & aerosols Perfume, hairspray, carpet freshener, pet grooming sprays, room sprays, vapes
Household products Detergents, polish, disinfectants, scented candles, new rugs or furniture “off-gassing”, silicone sealant, fresh paint
Environmental triggers Dust, damp wood, mould, oil fumes, cigarette smoke, some trees or plants
Crowded indoor air Theatres, shops, salons, or restaurants where several products and fragrances combine

Reactions were often described as immediate:

“Aerosols set me off straight away — I feel it in my chest before I even notice the smell.”

🧩 Why odours trigger symptoms

Odour sensitivity isn’t usually an allergy — it’s caused by airway hyperreactivity.
In these conditions, nerve endings in the bronchial walls become oversensitive.
When exposed to volatile organic compounds (VOCs), aerosols, or fine particles, the airways tighten and release inflammatory mediators — a reaction that’s stronger and longer-lasting in those with existing lung inflammation.

People with ABPA, Severe Asthma with Fungal Sensitisation (SAFS), or Chronic Pulmonary Aspergillosis (CPA) often have inflamed, mucus-filled, or scarred airways, making them far more reactive to irritants.

🧭 Factors that make reactions worse

Patients pointed out that it’s not just what’s in the air, but also:

  • Concentration – strong or enclosed fumes trigger faster responses

  • Combination – multiple scents together (perfume + cleaner + paint) are far harder to tolerate

  • Duration – prolonged exposure leaves lingering symptoms

💡 Tips for managing odour sensitivity

Plan ahead

  • Choose quiet times for haircuts, shopping, or social events.

  • Check if venues use air fresheners or scented cleaning products.

Control your environment

  • Use fragrance-free detergents and cleaning products.

  • Ventilate your home after cleaning or decorating.

  • Keep dehumidifiers and air purifiers running in damp areas.

Be prepared

  • Carry a reliever inhaler or antihistamine if prescribed.

  • Consider a FFP2/FFP3 mask in heavily fragranced or dusty places.

  • A small bottle of peppermint oil or menthol inhaler may help mask irritant odours temporarily.

Communicate

  • Let friends, family, or workplaces know that fragrances affect your breathing.

  • If public spaces (like theatres or salons) are overwhelming, it’s okay to step out — health comes first.

🧠 Understanding and empathy

“It’s not about disliking smells — it’s that my lungs treat them as an attack.”

For many, this sensitivity means planning life around exposure — avoiding crowds, timing visits, or even missing social events.
Recognising that these reactions are physiological, not psychological, can help families, friends, and employers offer real support.

❤️ Takeaway message

Odour sensitivity is part of the lived experience of reactive airway disease.
It isn’t always predictable, but understanding your triggers — and which scents are safe — can make everyday life much easier.
As one patient put it:

“If I can avoid mould, dust, aerosols, and detergents, I can generally stay well.”

By sharing these experiences, patients are helping others realise they’re not alone — and helping clinicians understand just how much “harmless” smells can matter.

Aspergillosis & Asthma: When Risks Peak Through the Year

Many people living with aspergillosis, asthma, or bronchiectasis notice that their symptoms change with the seasons.
This is no coincidence — environmental factors such as temperature, humidity, pollen, spores, and viral infections all vary through the year, and these can strongly influence both lung health and allergic or fungal disease.

Understanding these patterns can help you plan ahead, reduce exposure, and know when to take extra care.

🌸 Spring: Pollen and Early Spore Season

As temperatures rise, tree pollen (especially birch, oak, and plane) and Aspergillus spores begin to increase in outdoor air.
For people with Allergic Bronchopulmonary Aspergillosis (ABPA) or Severe Asthma with Fungal Sensitisation (SAFS), this can trigger cough, wheeze, and chest tightness.

  • Keep an eye on Met Office pollen and spore forecasts.

  • Open windows on dry days, but check for signs of mould indoors, especially around windows and bathrooms.

  • If you notice symptoms flaring every spring, let your respiratory team know — small medication adjustments may help.

📊 Data source: Met Office spore count data.

☀️ Summer: Soil, Compost, and Renovation Hazards

Warm, humid conditions mean fungi thrive — especially outdoors.
Compost heaps, garden soil, and grass cuttings can release very high levels of Aspergillus spores.
People with chronic lung disease, ABPA, or Chronic Pulmonary Aspergillosis (CPA) are at greater risk of exacerbations during this period.

  • If gardening or using compost, wear gloves and an FFP2/FFP3 mask.

  • Avoid turning compost heaps or cleaning bird feeders if you are immunocompromised.

  • Keep home humidity below 60% and ventilate well during warm spells.

🪴 Source: Protective mask and compost safety advice.

🍂 Autumn: Damp Homes and Viral Load

As the weather cools, we close windows and turn on heating — trapping moisture indoors.
This increases damp and mould growth, particularly in poorly ventilated areas.
At the same time, colds, flu, and RSV infections surge, all of which can make fungal or allergic conditions worse.

  • Use a dehumidifier and ensure air can circulate behind furniture.

  • Check for leaks, condensation, or cold corners.

  • Stay up to date with flu and COVID vaccinations if eligible.

❄️ Winter: Indoor Season and Medication Review

Outdoor spore levels are lowest in winter, but indoor exposure dominates — from bathrooms, humidifiers, and heating systems.
Viral infections remain a major trigger for asthma and ABPA flare-ups, and antifungal or steroid treatments may need review.

  • Keep homes warm but ventilated where possible.

  • Review your treatment plan with your clinical team, especially if you’re using steroids or biologics.

  • Contact your GP or specialist early if you notice an increase in cough, breathlessness, or mucus plugs.

🧭 Key Takeaway

Aspergillosis and asthma flare-ups often follow the seasons:

Season Main Risks Take Action
Spring Pollen, outdoor spores Monitor counts, check home for mould
Summer Compost, soil, renovation dust Use masks/gloves, avoid heavy exposure
Autumn Damp homes, viruses Dehumidify, ventilate, manage infections
Winter Indoor air, viruses Keep warm, review treatment

By spotting your personal pattern, you and your care team can plan ahead — reducing exacerbations and staying well all year.

🏗️ Damp, Dust and Indoor Air Quality

Essential Guidance for Builders, Contractors and Property Managers

(More information: aspergillosis.org/aspergillus-and-damp and aspergillosis.org/damp-homes-uk-policy-and-research)

💧 Why Damp Matters

Damp buildings damage both fabric and health.
When moisture gets trapped or ventilation is poor, it can promote:

  • Mould spores (Aspergillus, Penicillium, Stachybotrys)

  • Bacteria and microbial toxins from stagnant materials

  • Allergens from mites, birds, rodents, and decayed debris

  • Fine particulates (PM₂.₅ / PM₁₀) from dust, insulation, and sanding

  • Volatile Organic Compounds (VOCs) from paints, sealants, and adhesives

These pollutants reduce indoor air quality and can trigger coughing, wheezing, eye irritation, fatigue and, for some people, serious respiratory illness.
Asthma, chronic lung disease, and suppressed immunity are common in the population — and very young or elderly occupants are particularly vulnerable.

Every project should therefore apply moisture and air quality controls — not just hospitals or special buildings.

1️⃣ Identify and Stop the Moisture at Source

Before starting work, always inspect for water ingress and poor airflow:

  • Check for leaking roofs, gutters, downpipes, flashing, and plumbing.

  • Look for damp patches on walls, skirtings, insulation, or behind plasterboard.

  • Identify cold bridges and condensation points (e.g. metal lintels, window reveals).

  • Ensure ventilation pathways (vents, air bricks, extractor fans) are open and working.

  • Maintain indoor relative humidity below 60%.

  • Dry wet materials within 48 hours using fans, heat, or dehumidifiers.

  • Never seal or cover damp materials — fix the cause first.

2️⃣ Control Dust and Airborne Particles

  • Use M- or H-class extractors with HEPA filtration on all sanding, grinding, or cutting tools.

  • HEPA vacuum and damp-wipe after work — never dry-sweep or blow dust.

  • Contain work areas with plastic sheeting, zipper doors, and sticky mats.

  • Clean tools, boots, and PPE before leaving site.

  • Schedule dusty work when occupants can be absent and ventilate thoroughly afterward.

3️⃣ Handle Mould Safely – Especially Aspergillus

  • Aspergillus thrives on damp plaster, wallpaper paste, insulation, and chipboard.

  • Remove and bag visibly mouldy porous materials — don’t just spray or paint over.

  • Clean hard surfaces with detergent and dry fully.

  • Avoid fogging or biocides unless properly risk-assessed and ventilated.

  • Wear PPE: FFP3 respirator, gloves, goggles, disposable overalls.

  • Warn occupants if they have asthma, COPD, aspergillosis, or weakened immunity.

Further practical guidance:
🔗 aspergillosis.org/aspergillus-and-damp

4️⃣ Manage VOCs and Chemical Exposure

  • Use low-VOC paints, sealants, and adhesives.

  • Keep areas well-ventilated during application and drying.

  • Seal and store solvents away from occupied rooms.

  • Avoid heating or sealing rooms while solvent coatings are curing.

5️⃣ Protect Workers and Occupants

  • Isolate and ventilate the work zone.

  • Use HEPA extraction and regular cleaning.

  • FFP3/P3 masks and gloves for all dusty or mouldy tasks.

  • Double-bag and seal waste before removal.

  • Communicate with clients about health risks and ventilation needs, especially for homes with children, elderly, or medically vulnerable occupants.

✅ Best Practice Summary

Priority Good Practice
Check for water ingress & leaks Roofs, gutters, pipework, damp patches
Fix moisture sources first Prevent re-occurrence of mould
Dry within 48 hours Stop fungal/bacterial growth
Maintain RH < 60% Prevent condensation and damp
Ensure good ventilation Extractors, trickle vents, air bricks
HEPA dust control M/H-class vacuums & extractors
Use low-VOC products Reduce chemical exposure
Protect workers & residents PPE, containment, safe waste removal

🚫 Don’t

  • ❌ Dry-brush, sweep, or blow mouldy dust.

  • ❌ Trap damp under new finishes or sealants.

  • ❌ Paint over visible mould.

  • ❌ Block vents or air bricks.

  • ❌ Leave wet debris or bird droppings exposed.

⚠️ When to Escalate

Call a specialist if:

  • Damp or mould affects multiple rooms or structural elements.

  • Musty odours persist despite cleaning.

  • The property houses asthma, ABPA, CPA, transplant, chemo, or elderly occupants.

🫁 Understanding Chronic Cough in Aspergillosis

What the latest British Thoracic Society statement means for you

🌬️ Why This Matters

If you live with aspergillosis, Allergic Bronchopulmonary Aspergillosis (ABPA), or bronchiectasis, coughing can dominate your life. It’s tiring, painful, and socially awkward — especially when people assume it means infection.

Doctors used to see cough as just a symptom of another problem, but the British Thoracic Society (BTS) Clinical Statement on Chronic Cough in Adults (2023) recognises something new:

For many people, a cough can become a condition in its own right — caused by airway and nerve hypersensitivity, not just infection.

This matters for aspergillosis patients because fungal allergy and inflammation make the airways especially sensitive.

💡 What Is “Chronic Cough”?

A chronic cough is one lasting eight weeks or more.
It may be:

  • Dry – little or no mucus

  • Productive – thick sputum (common in bronchiectasis or chronic aspergillosis)

  • Triggered by dust, cold air, perfume, or strong scents

For people with aspergillosis, several overlapping causes may exist:

  • Fungal colonisation or infection

  • Allergic inflammation (ABPA)

  • Bronchiectasis and mucus retention

  • Reflux or post-nasal drip

  • Nerve hypersensitivity

This is why one treatment rarely fixes everything — different “treatable traits” must be addressed together.

🧬 Why It Happens

1️⃣ The Hypersensitive Cough Reflex

People with aspergillosis often develop overactive airway nerves — so normal irritants like dust, scent, or cold air trigger coughing fits.

This “cough reflex hypersensitivity” happens because:

  • Ongoing inflammation damages the airway lining.

  • Nerve endings in the throat and lungs become over-responsive.

  • Even mild triggers set off powerful reflexes.

This is a real physiological process, not psychological.
It’s why cough can continue even when infection is under control.

2️⃣ Treatable Traits – Finding the Real Drivers

Treatable Trait What It Means What Helps
Airway infection or colonisation Persistent fungi or bacteria Antifungal or antibiotic therapy, sputum tests
Allergic inflammation ABPA or asthma-type airway swelling Corticosteroids, biologics (e.g., mepolizumab, benralizumab)
Cough reflex hypersensitivity Overactive airway nerves Speech therapy, nerve-modulating medication
Airway clearance problems Mucus that’s hard to shift Physiotherapy, saline or mucolytic therapy
Reflux or postnasal drip Acid or sinus drainage irritation Reflux management, ENT care

Identifying these traits helps your clinician personalise treatment.

💊 Medications That Can Cause or Worsen Cough

The BTS statement highlights that some medicines can trigger or amplify chronic cough — especially in people with already-sensitive lungs.

🔹 ACE Inhibitors (Blood pressure or heart disease)

Examples: Ramipril, Lisinopril, Enalapril, Perindopril

  • Can cause a dry, tickly cough due to bradykinin build-up.

  • Happens in ~1 in 5 users, sometimes months after starting.

  • GP can switch to a similar drug (ARB – e.g., losartan) that doesn’t cause cough.

🔹 Beta Blockers (Heart or migraine medicines)

Examples: Atenolol, Propranolol, Bisoprolol

  • May tighten airways, worsening wheeze or cough.

  • Safer “lung-selective” versions exist but should still be monitored.

🔹 Inhalers

Examples: Fluticasone, Budesonide, Salbutamol

  • Can irritate the throat if used without a spacer or if technique is poor.

  • Always rinse or gargle after use, and ask your pharmacist to review inhaler technique.

🔹 Antifungal or Reflux Medicines

  • Antifungals (itraconazole, voriconazole) don’t directly cause cough, but reflux or nausea can trigger coughing indirectly.

  • PPIs (omeprazole, lansoprazole) usually help reflux-related cough, but long-term use should be reviewed regularly.

🔹 Other Drugs

  • Amiodarone, methotrexate, and some biologics can rarely cause cough due to lung inflammation.

  • Nasal sprays or lozenges with menthol/alcohol may irritate already-sensitive airways.

💬 If you suspect a medicine is contributing, don’t stop it suddenly — speak to your doctor or pharmacist first.
They can review interactions using the
👉 BNF Interactions Checker – NICE Medicines Guidance.

🔍 How Doctors Assess Chronic Cough

BTS recommends a structured pathway:

  1. Basic tests: chest X-ray, spirometry, bloods (eosinophils, IgE), FeNO if available.

  2. Further tests: CT scan, allergy or sputum studies if initial tests are abnormal.

  3. Trait-based review: identifying overlapping issues — fungal, allergic, nerve-related, or reflux-related.

  4. Specialist referral: to a Cough Clinic or Aspergillosis Centre if symptoms persist.

🧴 Pharmacists: Your Safety Specialists

Pharmacists — hospital or community — are crucial for managing long-term cough and medication safety:

  • Check for cough-inducing drugs or interactions.

  • Advise on best timing for antifungal and steroid doses.

  • Help switch to fragrance-free personal or cleaning products.

  • Liaise with your GP and consultant to fine-tune treatment.

🧭 Regular medication reviews every few months can prevent small problems becoming major triggers.

💬 How It Feels — and Why It’s Misunderstood

People with aspergillosis often describe:

“A tickle that turns into a spasm I can’t stop.”
“People think I’m ill, but it’s just the air or perfume.”

This happens because your airway nerves and immune cells are already primed.
Coughing doesn’t mean you’re infectious — it’s your body’s protective reflex in overdrive.

🩺 What Helps Most

  • Optimise your aspergillosis and ABPA treatment.

  • Cough-control physiotherapy or speech therapy for nerve-related cough.

  • Airway clearance techniques for mucus.

  • Identify and avoid irritants: perfume, smoke, strong detergents, cold air.

  • Ask about biologics if inflammation remains active despite steroids.

  • Use nerve-modulating medicines only under specialist advice.

🧘 Emotional Health Matters Too

Living with a chronic cough can cause anxiety, embarrassment, and isolation.
Support from counsellors, CBT therapists, or patient groups helps manage this stress — and can actually reduce cough frequency through better relaxation and breathing control.

🌱 Key Takeaway

Chronic cough in aspergillosis isn’t “just a symptom” — it’s often a mix of airway inflammation, fungal allergy, nerve hypersensitivity, and sometimes side effects of medicines.

The good news is that every contributing factor is treatable once identified — and cough can improve significantly with the right combination of medical, physical, and environmental care.
