Actual (reported)This online study aims to explore the benefits of nature for mood and cognition in persons with and without Parkinson's disease. For the purpose of this survey, "natural environment" refers to places that primarily consist of natural elements, such as vegetation, water bodies, and landscapes. This includes greenspaces (such as parks, gardens, neighborhood streets lined with trees, forests, or nature reserves) bluespaces (such as next to beaches, lakes, rivers, ponds, or waterfronts), and desert regions, among others.
