The modern lifestyle, high levels of stress, and pollution negatively affect the general public health of individuals, primarily the population living in urban environments. The new health paradigm, as well as the World Health Organization, emphasizes the importance of prevention and defines health as a state of "completemental and physical well-being." The significance of health as a fundamental resource in modern times is also defined through the Sustainable Development Goals, specifically Goal 3, "Good Health." The ecological aspect of sustainability is closely linked to environmental preservation, and a healthy environment defines the causes of diseases or illnesses, as people absorb stimuli from their surroundings through psycho-neuro-endocrine mechanisms in the body. These causes are primarily based on stress levels, and many international studies have confirmed that natural elements from the environment, such as greenery, water, fresh air, colors, and sounds from nature, positively affect stressors in the surroundings. The spaces in cities that possess these above mentioned positive characteristics are open green spaces. In the territory of the municipality New Belgrade, various types of these space sexist, while most commonly used are linear parks along the banks of the Danube and Sava rivers, as well as small parks within the characteristic mega-blocks. This paper focuses on analyzing and researching the importance of open green spaces in New Belgrade in the context of their impact on users, particularly from the perspective of frequency and dynamic of usage, as well as users' subjective perceptions. The expected results provide the opportunity for adequate adaptation and potential improvement of the physical and functional characteristics of open green spaces, with the aim of encouraging more active usage of the sespaces in urban environments.
