Abstract: Green rooftop space is beneficial to population health and is an important workplace for promoting healthy and sustainable human settlements. In an attempt to determine the restorative effects of green rooftop space on health, three specific scenarios were selected to explore the restorative potential of green rooftop space. With the help of biofeedback and state of mind measures, the effects of green rooftop space exposure on physiological and psychological indicators were analyzed. The results showed that: Although slight differences in the changes of psychological and physiological indicators, both confirmed the restorative effect of green rooftop space; Three types of rooftop space had different degrees of health restorative benefits, with the best restorative effect being found in the space of the water body; There was a significant positive correlation between the changes in some psychological and physiological indicators. The findings help to raise awareness of the restorative value of green rooftop space, further support the argument that green rooftop space promotes physical and mental health, and provide a theoretical basis for the design of green rooftop space based on the healthy concept.
