Children playing outside during Arizona summers can face 100 days or more of temperatures north of 100°F. Too often playgrounds use heat-retaining, unnatural surfaces in the middle of parks with no shade, especially in Phoenix. These unshaded playgrounds can act as mini heat islands, which can disincentivize physically active play or even lead to burns.
ASU urban climate researchers Jennifer Vanos and Ariane Middel believe proper shading of playgrounds may be a solution.
