Know your asthma triggers: 7 hidden causes lurking at home and smart ways to avoid them

Asthma does not always begin with a dramatic attack.

In many cases, it builds slowly, shaped by the spaces people live in every day.

While polluted outdoor air often gets the blame, what lingers indoors can be just as harmful, if not more.As Dr Mohit Kaushal, Senior Consultant, Pulmonology and Critical Care, Fortis Hospital Mohali, explains, “Outdoor air pollution is one of the leading causes of breathing problems in young individuals.

But the air inside your homes may be just as guilty and far less talked about.

For someone already sensitive, this can mean frequent coughing or tightness in the chest, especially at night.A practical fix works well here.

Wash bedding weekly in hot water and use allergen-proof covers.

It may sound simple, but it reduces exposure more than most realise.

Pet dander: Love comes with a costPets bring comfort, but their skin flakes and fur carry proteins that can trigger asthma.

These particles stick to clothes, walls, and furniture for months.Over time, exposure can reduce lung function in sensitive individuals.

Many do not connect mild breathlessness with their pets, which makes this trigger easy to miss.Keeping pets out of bedrooms helps.

Regular grooming and vacuum cleaning are more effective than sweeping, which often just spreads particles.Incense sticks and mosquito coils: The cultural blind....
