The evolutionary process that led to the emergence of anatomically modern humans took 6 -7 million years and 99 percent of this time was spent in natural surroundings, according to a 2016 review by Japanese scientists in the International Journal of Environmental Research and Public Health. “The gap between the natural setting,” the article explains, “for which our physiological functions are adapted, and the highly urbanized and artificial setting that we inhabit, is a contributing cause of the ‘stress state’ in modern people.”
The review goes on to evaluate current studies and concludes that the beneficial effects of “nature therapy” (including time spent in gardens, forests, and urban green spaces) extend to the central nervous system, autonomic nervous system, endocrine system, and immune system.
