This clip discusses the findings of the Children’s Health Study by the Southern California.
Excerpt: “In healthy children, lungs grow as the body develops, but the greatest growth rate is during puberty. From ages 10-14, healthy children see their lungs grow by about 12% each year. By the late teens or early twenties, lungs have essentially stopped growing. The Children’s Health Study shows that during the crucial puberty years, the lungs of a child exposed to high levels of pollution will grow 10% less each year. Over a period of four years, that is a significant deficit in lung function compared with kids growing up in low-pollution neighborhoods.”
