Here’s clear advice we would give to people with breathing sensitivities like ABPA (Allergic Bronchopulmonary Aspergillosis), CPA (Chronic Pulmonary Aspergillosis), Asthma, Bronchiectasis, or COPD:

✅ 1. Check Air Quality Before Going Out

• Use air quality apps daily (especially if planning exercise or outdoor errands).

• Recommended free apps/sites:

  • AirVisual / IQAir (worldwide PM2.5 tracking – nice smartphone APP)

  • Plume Labs (detailed forecasts + recommendations)

  • DEFRA UK Pollution Forecast (official government site)

  • Met Office (Official government site)

• Key numbers to know:

  • PM2.5 > 35 μg/m³ → unhealthy for lung patients

  • PM10 > 50 μg/m³ → increased irritation risk

  • “Moderate” or worse on DEFRA scale → minimize outdoor exposure if possible.

✅ 2. Time Your Outdoor Activity Smartly

• Early mornings often have higher pollution (overnight trapping by cold air).

• Mid-morning to early afternoon (10 am – 2 pm) often cleaner if sunny and breezy.

• Avoid rush hours — pollution is highest when traffic is heavy.

🔵 Good practice:

Walk, shop, or garden during cleaner, warmer parts of the day if possible.

✅ 3. Mask Up on Moderate or Higher Pollution Days

• If AQI (Air Quality Index) is moderate or worse:

  • Use a lightweight FFP2/N95 or better mask outdoors.

  • Valved masks are better for breathing comfort but remember: valve masks protect you, not others.

• Reusable masks with PM2.5 filters are also helpful (e.g., Cambridge Mask Pro).

✅ 4. Avoid High-Risk Locations

• Don’t walk along busy main roads if you can avoid it.

• Stay a block back from heavy traffic routes — pollution drops dramatically even just 100 meters away!

• Avoid construction sites, open fires, industrial areas, and bus depots.

✅ 5. Protect Indoors Too

• Close windows on bad air days (especially facing traffic).

• Use HEPA air purifiers indoors if you can — they trap fine pollution particles and mold spores too.

• Shower/change clothes after coming inside if you’ve been out during very polluted times — particles stick to hair and clothing.

✅ 6. Listen to Your Body

• If you feel tight-chested, start coughing, or wheezy after being outside:

  • Stop, mask up immediately if you haven’t.

  • Use a rescue inhaler if prescribed (salbutamol, Ventolin).

  • Get into cleaner air (indoors with windows shut).

Even if pollution readings seem only “moderate,”
if your lungs react badly, trust your body first, not the number.

🎯 Simple Golden Rules for ABPA/CPA patients:

🧡 Quick “Air Quality Survival Kit” for Sensitive Lungs

• Small FFP2/N95 mask (valved for comfort)

• Small bottle of water (stay hydrated — pollution thickens mucus)

• Rescue inhaler (if prescribed)

• Air quality app installed and checked daily

• Lightweight jacket/hat to minimize particles on hair and skin

🔵 Final Mindset Tip:

🌿 You don’t have to avoid outdoors forever —
you just need to be strategic about which days and where you go.

“Pick your battles. Choose your air.”
