More green space is linked to less stress in deprived communities: Evidence from salivary cortisol patterns
This study, published in ‘Landscape and Urban Planning’ uses both self-reported measures of stress and general wellbeing as well as self-administered salivary cortisol sampling to measure stress levels against varying levels of exposure to green spaces in a deprived city community. Results indicate significant relationships between self-reported stress, diurnal patterns of cortisol secretion and quantity of green space in the living environment. The authors suggest that the need for adequate levels of nearby green space is an important message for landscape and urban planners when designing new residential development, renovating existing urban infrastructure or consulting on land use priorities.
A significant example to test the health effects of green in urban planning policies! It seems it's possible "register" this issue, the other question is: Is it necessary do it?
