More green space is linked to less stress in deprived communities: Evidence from salivary cortisol patterns

► The biological impact of exposure to green space encountered by a deprived population in their home environment is shown. ► Diurnal patterns of participants' salivary cortisol, self-report stress and objective measures of green space were recorded. ► Using a small, UK, urban sample, a significant positive correlation between cortisol slope and % green space was found. ► There was a significant negative correlation between self-reported stress and % green space. ► Ecologically valid and objective measures provide evidence for a salutogenic environment-body interaction.
