Padma Bhushan awardee doctor Ashok Seth shares what actually works to reduce pollution inside home

Yet again, Delhi woke up to thick smog on November 15, 2025, with the AQI touching 386 at 8 a.m. The city felt heavy, and many homes sensed it too, as the polluted air seeped indoors. Padma Bhushan awardee and Chairman of Fortis Escorts Heart Institute, Dr Ashok Seth, has raised an urgent concern. He explained that this level of pollution harms everyone and hits elderly people and those with heart or lung issues the most. His warning also carried a sense of care, because his advice focused on practical steps that families can use right away.


Homes can offer shelter, but only when the air inside is kept clean and calm. His guidance helps people create that safe space by using small habits that strengthen the body and reduce the load on the lungs. These steps also help families feel more prepared when the air outside turns harsh.

Limit outdoor exposure with purpose

Dr Seth told PTI that stepping out during heavy smog should be avoided as much as possible. When going out becomes necessary, an N95 mask is essential. These masks cut the entry of PM2.5 particles in a measurable way and protect the lungs during long commutes or simple errands. Quick trips, planned timings and masked travel form the core of safe movement on high-pollution days.

Strengthen protection through timely vaccines

Respiratory infections rise sharply in polluted months. Dr Seth advised vulnerable groups to stay updated on pneumonia and flu vaccines. These infections often flare up when the air is toxic, adding further stress to the heart and lungs. Vaccination acts like a shield, reducing the chance of complications.

Shift workouts indoors without cutting activity

High pollution pushes harmful particles deeper into the lungs during heavy breathing. Dr Seth noted that outdoor exercise should be avoided during such periods. Gentle home-based workouts such as static jogging, stretching or yoga allow people to stay active without inhaling polluted air. These routines maintain fitness and protect the respiratory system.

Use air purifiers wisely, not randomly

An air purifier can make a noticeable difference when used in the right room and run for long enough hours. Dr Seth recommended keeping at least one purifier at home if possible. Placing it in the bedroom or the living area creates a cleaner zone where the family spends most of the time. Regular filter checks keep the machine efficient.

Add green plants for cleaner corners

Indoor plants offer a gentle way to support air quality. Dr Seth encouraged keeping green plants at home for their natural ability to trap dust and refresh indoor air. Peace lilies, spider plants and money plants fit well in Indian homes. Their slow, steady purification helps the space feel breathable.

Support the body from within

Hydration, nutritious meals and a calm state of mind are simple but effective. Dr Seth reminded people that good immunity helps the body deal with pollution stress. Water supports detoxification. Fresh fruits, vegetables and whole grains supply antioxidants. Rest balances the body’s response to pollution.
