Introduction

Urban green spaces, such as parks and gardens, are increasingly recognized for their potential to enhance public health and well-being. As urbanization continues to rise globally, understanding the impact of these green spaces on various health outcomes is crucial for urban planning and policy-making.

Key Insights

Positive Health Outcomes:
- Urban green spaces are associated with lower mortality rates, reduced heart rates, and decreased violence .
- Increased physical activity, improved mood, and better attention levels are linked to exposure to urban green spaces .
- Higher perceived quality and quantity of urban green spaces are modestly related to increased life expectancy and healthy life expectancy.
Mental Health and Well-being:
- Frequent interaction with green spaces correlates with higher levels of well-being and psychological health .
- Changes in perceptions of green space quantity are positively associated with psychological well-being over time.
Social and Environmental Benefits:
- Green spaces provide areas for social interaction and community activities, contributing to social well-being .
- They help mitigate urban heat, offset greenhouse gas emissions, and manage stormwater, which indirectly benefits public health .
Context-Dependent Effects:
- The health benefits of green spaces can vary based on economic context; richer cities see more positive health outcomes, while poorer cities may experience reduced public health with increased green space.
- Proximity to green spaces affects well-being, with optimal benefits observed for residents living 1-5 km away from green spaces.
Challenges and Considerations:
- The relationship between green spaces and health is complex and multifactorial, influenced by accessibility, quality, and functionality of the green spaces.
- There is a need for more rigorous studies to generalize findings and understand the mediating effects of green spaces on health .

Conclusion

Urban green spaces play a significant role in enhancing public health and well-being by promoting physical activity, improving mental health, and providing social and environmental benefits. However, the impact of these spaces can vary based on economic context and proximity. Future urban planning should consider the quality, accessibility, and functionality of green spaces to maximize their health benefits. More comprehensive and rigorous research is needed to fully understand and optimize the health impacts of urban green spaces.
