Green spaces lead to healthier births:

Maternal exposure to residential greenness is associated with higher birth weight, first linked to lower risk of very low birth weight and very preterm deliveries.

Nature reduces maternal stress:

Beneficial associations were found between residential greenness and reduced maternal stress, measured by lower hair cortisol concentrations.

Living near greenery is associated with lower cancer incidence: 

A 21-year study shows that higher cumulative residential greenness is associated with lower incidence of lung, bladder, breast, prostate, and skin cancer.

What is “variance of greenness”?

A novel metric showing health benefits are strongest where greenness is highest, possibly indicating that higher biodiversity and mixed land use enhance positive effects.
