In cities, the urban forest is a green infrastructure system that provides a variety of environmental, economic, social, and health benefits and functions. Although the environmental advantages of urban trees are widely known, no study has yet looked at how urban trees impact human health. This review offers a thorough overview of current research on the health effects of urban trees, which may be used to guide future research, policy, and nature-based public health initiatives. Keywords reflecting human health, environmental health, and urban forestry were utilized in a systematic search. The research examined had a wide range of objectives and methods, but they all point to significant health consequences linked to people's exposure to trees. This study will aid future research and practice by demonstrating why trees should be deliberately promoted as a social determinant of public health in urban forest design and management
