Asthma is a noncommunicable disease, meaning it doesn’t spread from person to person. We don’t know exactly what causes asthma, but we do know it’s a combination of genetic and environmental factors. Some of these factors you’d probably guess. For example, if a child is around tobacco smoke, he’s more likely to develop asthma. Other factors are more surprising.

Phthalates are the group of chemicals that make plastic flexible. And they’re everywhere-- from school supplies to nail polish and even blue jeans. A study at Columbia’s Mailman School of Public Health was unable to find any American woman who weren’t exposed to phthalates, but they did find that those with a higher level of phthalates in their urine were 72% to 78% more likely to have children who develop asthma.
