Why home environment matters for Bronchiectasis
Damp, mould, and chronic high indoor humidity directly worsen bronchiectasis through repeat respiratory infection and biofilm-related airway inflammation. Cold homes drive acute exacerbations through reactive airway constriction. Inadequate ventilation traps respiratory pathogens and allergens in occupied rooms. Indoor combustion pollution (gas hobs, open fires) compounds the airway-inflammation burden.
UK prevalence: Bronchiectasis affects approximately 1 in 1,000 people in the UK, with prevalence rising with age — affecting around 1 in 350 people aged 70+. Underdiagnosis is common and many cases are misclassified initially as COPD or recurrent bronchitis.
