Does Nature Exposure actually make a difference, or is it overhyped?

A systematic review and meta-analysis of cohort studies in The Lancet Planetary Health found greater green space exposure is associated with lower mortality, a finding reinforced by an independent systematic review of residential green space and by a dedicated meta-analysis in older adults finding lower mortality and cardiovascular risk. Weighing the data: Nature Exposure looks well-studied but modest in effect — the evidence is rated strong (75/100), but its estimated impact on longevity is comparatively small (46/100).
