Dose of Nature’s curated collection (page 7) compiles peer‑reviewed and field studies showing that exposure to nature—through viewing, time in green spaces, forest‑bathing, natural sounds and scents—produces measurable benefits (reduced stress and rumination, improved mood and sleep, boosted immune function, better cognition and longevity, and increased prosocial behaviour). Included under "Your Capital And the Power of Generosity" — PART 1: The Purposeful Investor — this reference is cited to substantiate the book’s claim that allocating capital to green infrastructure and nature‑based health interventions delivers tangible health and social returns that strengthen the purposeful investor case.
