Asthma worsening at night? Pulmonologist Dr Nalini Nagalla asks you to check your home for these 5 hidden triggers

Dust mites in bedroom pillows, mattresses, curtains, rugs, stuffed toys, and old upholstery can trigger asthma. Dr Nalini Nagalla warns that sleeping surrounded by these allergens for hours often causes morning sneezing, blocked nose, nighttime cough, or chest tightness.

Indoor triggers often cause asthma to worsen at night, early morning, or after long hours indoors. Patients may notice symptoms improve outdoors but worsen after returning home.

Pulmonologist Dr Nalini Nagalla, HOD and senior consultant at Arete Hospitals, shared five hidden triggers inside homes that can worsen asthma.
