“The harmful particles and gases in polluted air, when inhaled, can lead to systemic inflammation and oxidative stress, which disturb gut health and impact the microbiome -- the collection of trillions of bacteria in our intestines that play a critical role in digestion, immunity, and overall health,” Dr Sethi said.
The health experts recommend limiting outdoor activities during peak pollution times, typically in the early morning and evening; and using masks, especially in highly polluted environments.
