My client, who had recently retired from Japan, frowned as I praised his daily park walks. "This is not shinrin-yoku," he sighed. "In Japan, forest bathing trails have blood pressure stations and meditation nooks. Here, I just wander around taking selfies with squirrels and pretending it’s therapy."
He had a point. In Japan, forest bathing isn’t just a nice idea—it’s doctor-prescribed and backed by research that probably makes pharmaceutical execs sweat. Unlike hiking, which is just walking in expensive shoes, forest bathing is about fully immersing your senses in nature with guided intention. And it works. A study from Nippon Medical School found that just two hours among trees increases natural killer cell activity by 56% and lowers cortisol by 12.4% (Li, 2010). Most therapists can’t rewire your immune system, but apparently, an oak can. So honestly—who’s the real expert here?
