Living near greenspace makes it less likely that people will experience postpartum depression (PPD). Sun and colleagues found that “A reduced risk for PPD was associated with total green space exposure based on street-view measure [500 m buffer. . .], but not NDVI [normalized difference vegetation index], land-cover greenness, or proximity to a park. Compared to other types of green space, tree coverage showed stronger protective effects. . . . Street view-based green space and tree coverage were associated with a decreased risk of PPD. The observed association was primarily due to increased tree coverage, rather than low-lying vegetation or grass.”
