Warmer temperatures may cause unhealthy air

Warming temperatures may have you wanting to spend more time outdoors. But warm weather can mean more unhealthy air.

 Susannah Fuchs of the American Lung Association says our region's sunny, hot, nearly windless summer weather creates the perfect conditions for the formation of ozone and smog. And Fuchs says we're also hit hard by particulate pollution. “The very, very fine dust that can easily bypass the body's natural defenses and get into lungs and even bloodstream and cause all kinds of respiratory effects and also cardiac effects,” Fuchs said.  Fuchs says children, the elderly, people who work outdoors, and people with respiratory problems are most at risk, but that everyone should avoid outdoor activities during times of peak air pollution.
