green space exposure associated with increased positive emotions
Exact: 0.10
Urban green spaces are associated with increased positive emotions in older adults and those with dementia (effect size 0.10)
A positive effect size of 0.10 for increased positive emotions was identified in the meta-analysis across 37 studies. This supports the role of urban green spaces — particularly community gardens — in fostering emotional uplift and well-being among older adults and people living with dementia.
The specific performance of these green spaces is as follows: reduced incidence of dementia (-0.06), improved social participation (0.14), increased physical isolation (0.54), reduced anxiety (-0.28), relieved depression, relieved mental disorders (-0.32), calmed agitation (-0.06), increased positive emotions (0.10), reduced sadness and anger, improved quality of life, enhanced cognitive function (0.52), and improved sleep.
