Researchers at the University of Southern California have found that children in Los Angeles have much better lung development than a similarly aged group did in the 1990s.
These are some of the ways in which millennial kids are breathing easier than their ’90s-era counterparts, according to the research:
• Their lungs grew 10 percent faster. This quickened development correlates with diminished levels of small particulate matter and nitrogen dioxide (40 percent lower than levels in the ’90s).
• Eight percent of study subjects showed impaired lung function in the mid-90s and 6 percent did a few years later. That number dropped to under 4 percent for mid-2000s kids, suggesting a gradual improvement in public health.
