Seniors Avoid the Hospital With Nature

New research has found that exposure to natural environments may reduce the risk of hospitalization for older adults with Alzheimer’s disease, related dementias and Parkinson’s disease. The cohort study included approximately 62 million Medicare beneficiaries aged 65 years or older that lived in the contiguous United States from 2000 to 2016. Researchers looked at ZIP-Code-level greenness, percentages of park cover and blue space (water) cover, as well as hospitalizations. They found that exposure to greenness, park cover and blue space cover reduced hospitalizations for patients with Parkinson’s. Greenness—but not park or blue space cover—was associated with a lower risk of hospitalization due to Alzheimer’s disease and related dementias.
