52%
more than half of reviewed studies linked restoration to mental health outcomes
Majority of studies connected psychological restoration to mental health
A systematic review of 46 peer-reviewed studies on psychological restoration and the 2030 Agenda targets found that 52% of the studies reported links between restorative experiences in natural environments and mental health outcomes, such as attention recovery and emotional regulation. By comparison, far fewer studies addressed connections to education (20%), sustainability (7%) or peace building (2%).
For anyone working on schools, campuses or public green space, this indicates that the strongest existing evidence base ties nature contact to mental health recovery specifically, more than to learning outcomes or sustainability goals. Arguments for restorative natural settings find their firmest support in mental health benefits; claims about educational or sustainability gains from the same spaces rest on a thinner literature.
The evidence for the mental health link itself is well supported within this review, drawn from over half of 46 studies across the field. However, this is a count of how many studies reported an association; it does not measure effect size or causal mechanism, and the review's scope is limited to studies indexed in Scopus and Web of Science addressing these specific 2030 Agenda targets.
Education
While 52% of the studies reported links between psychological restoration and mental health outcomes, fewer addressed connections to education (20%), sustainability (7%) or peace building (2%).

Architect
A nature view needs 35 per cent greenery to lift satisfaction
When the value engineering round opens and the glazing spec is first in line to be cut, you defend a nature view only by naming the effect figure that justifies it.
Asset manager
No certification premium attaches to the nature view on its own
A certification premium prices the whole label into rent and exit value, but it never tells you which single measure inside the building earned it.
Corporate real estate manager
Outward views reach staff cost through sleep and stress
Optimised daylight and views came with 37 minutes more sleep and 42 per cent higher cognitive scores, and a 2006 REHVA guidebook puts staff cost at 100 to 200 times a building's energy cost.
Developer and investor
No study ties a rent premium to the nature view
Nature views change measurable outcomes in people; the link from there to rent stays a category average, not a per-building figure.
HR manager
A view of nature restores attention
Berman and colleagues validated attention restoration on a backwards digit-span task, and cognitive control is rated strong; on retention there is one study, and it dates from 1998.
Marketing manager
A nature-view claim is safe only as a description of the view
For the real estate marketing lead: a nature-view study measured 37 extra minutes of sleep under one tested condition, and this worksheet sets the boundary an exposé sentence must keep to pass an advertising review.
Workplace strategist
Nature views lower reported stress and sharpen attention
Boubekri and colleagues measured 37 more minutes of sleep and a 42 per cent gain on cognitive scores: a capex paper defends that figure only by naming the author and the limit a finance committee will probe first.
