Pollens, yes. Dust yes. Cigarette smoke, yes. Pets, perhaps. Just in the prior entry, I've noted how air pollutants correlation to street traffic can contribute to asthma risks. All these make sense. But violence? What's the connection of exposure to violence relate to asthma?.

Preliminary results from on-going studies suggest that the stress caused by environmental exposure to violence is significantly linked to both poorer lung function in children and asthma exacerbations. There is some speculation about plausible stress mechanisms that might be responsible for this.
