SINGAPORE: People living with asthma are most vulnerable when taking a breath of air, yet their use of widely prescribed inhalers to help them breathe better contributes to the worsening of air quality.

Doctors say asthma patients should be managing their conditions better instead of turning to the inhalers frequently for treatment, to prevent more damage to the environment.
