Explainer
Returning to nature has a specific, studied practice behind it in Japan, developed and formally researched well before it became a global wellness trend.
Where Shinrin-Yoku Started
Japan's Ministry of Agriculture, Forestry and Fisheries coined the term shinrin-yoku, meaning forest bathing, in 1982, launching a national program encouraging time in forests as preventive health care, distinct from hiking or exercise-focused outdoor activity.
What the Studies Measured
Subsequent research, much of it led by Japanese physiologist Qing Li, measured reduced cortisol levels and increased natural killer cell activity in participants after forest visits compared to urban walks, some of the more frequently cited physiological findings in nature-based wellness research.
Returning to Something Specific, Not Vague
Sacred nature grounding, read through this research, isn't a vague sentiment, it points to a specific, measurable practice: unhurried time spent deliberately present in a forest environment, not just being outdoors in general.
