City parks and green spaces help counter heat, boost biodiversity, and instill a sense of calm in the urban jungle.
They also help slow biological aging, with people who have access to green spaces found to be on average 2.5 years biologically younger than those who do not, according to a new study published Wednesday in Science Advances.
"Living near more greenness can help you be younger than your actual age," said Kyeezu Kim, the study's lead author and a postdoctoral scholar at Northwestern University's Feinberg School of Medicine.
