Urban greenness affects people’s physical and mental health. Residential greenness is associated with reductions in cortisol levels after six months in patients with chronic heart failure undergoing rehabilitation.

Target audience
Healthcare professionals and urban infrastructure coordinators.
The problem
Heart failure accounts for the majority of hospitalizations for cardiovascular diseases. It has been found to increase cortisol levels, which increases, and is associated with overall mortality. Urban greenery can improve physical and mental health and reduce stress.
What we did and why
Urban greenness reduces the burden of physiological stress and improves cortisol levels, which, in turn, improves the condition of people with cardiovascular diseases. We identified an association between changes in cortisol levels at six months with exposure to green surroundings in urban patients with short-term and long-term aerobic training as needed during rehabilitation. Greater damage may be related to cortisol concentration disorder in patients after rehabilitation, related to health disorders in heart failure.
Our study’s contribution
We showed that changes in cortisol levels were significantly related to the greenness of the residential environment. Interestingly, a stronger effect of environmental greenness on cortisol reduction was observed when cortisol samples were taken after 10 AM.
Impacts for city policy and practice
We leave cities with two issues to consider.
Firstly, the more green spaces in the city and the better their availability – the greater the possibility of sustainable mobility. Secondly, natural elements in cities can contribute to improving urban air, microclimate regulation, and also can improve mental health by reducing stress.

The elderly should be able to travel and have fun like everyone else and use urban spaces easily, and on this basis, it is necessary to identify dimensions of an age-friendly city that provides the possibility of planning for such environments. We present an approach of bringing the WHO Age-Friendly City framework into urban planning strategic decision-making by using the AIDA (Analysis of Interconnected Decision Areas) model.
We conducted a citizen science project to engage with current residents in higher density residences in Northern Sydney to explore the positive and negative aspects of their lived experiences on their health and wellbeing. Together, we identified the elements that residents of these communities value as well as those with potential negative impacts that could be mitigated through good planning and design.
Cities urgently need systemic health checks. Without them, they keep fixing symptoms, wasting scarce budgets, while hidden risks grow. This proposed approach helps cities understand their true health and activate their self-healing capacity instead of constantly firefighting.
