Definition
Nature exposure — time in green space, blue space, or natural environments — has documented effects on mood, cognition, cardiovascular measures, and immunity, though effect sizes vary.
Why it matters
The evidence base is real. So are inflated marketing claims. Balance helps.
The Science
Roger Ulrich’s hospital study, attention restoration theory (Kaplan), and forest bathing research all support genuine effects of nature exposure on stress and cognition. Effect sizes are modest but consistent.
The NSI Perspective
NSI treats nature exposure as one legitimate input among several.
Clinical Implications
Prescribing nature contact is a legitimate part of care, without inflating claims.
Practical Application
Time outside, most days. That is the practice.
