Moms who live in greener spaces give birth to healthier children. Hystad and his team conducted an elaborate study examining, “associations between residential greenness (measured using satellite-derived normalized difference vegetation index (NDVI) within 100 meters of study participants’ homes) and birth outcomes in a cohort of 64,705 singleton births [one baby at a time, not twins, etc.] (from 1999–2002) in Vancouver, British Columbia, Canada.” They determined, after eliminating other potential explanations, such as neighborhood air pollution, noise, walkability, and distance to the nearest park, that “Increased residential greenness was associated with beneficial birth outcomes in this population-based cohort,” such as higher birth weights and fewer preterm births.
