Mental health conditions are one of the main causes of the overall disease burden worldwide, and this raises the demand for accessible and cost-effective infrastructure that improves mental health. Growing up in urban environments is associated with a higher risk of developing psychiatric disorders.

This systematic review will examine the correlation between green space and mental health, the mechanism by which green space improves mental health, and some mediating factors that affect the results. The results show a positive correlation between exposure to green space and residents mental health, suggesting that green space does play a part in the promotion of residents well-being, thereby ensuring their mental health.
