Forest bathing, also known as shinrin-yoku (深林浴), originated in Japan in the 1980s. Unlike hiking or exercising in nature, forest bathing is a mindful, immersive experience of simply being in nature – breathing deeply, walking slowly, and fully absorbing the sights, sounds, and smells of the forest.
It is not about fitness, but healing through nature.
“Forest bathing is like a reset button for your brain and body.” – Dr. Qing Li, Nippon Medical School, Tokyo

🌱 How Forest Bathing Works: The Science Explained
Forest environments emit phytoncides (antimicrobial compounds from trees like pine and cedar). When inhaled:
- 💪 They increase immune cell activity
- 🧘 They trigger parasympathetic nervous system (rest-digest mode)
- 😌 Reduce cortisol and support emotional regulation
“Just 2 hours of forest exposure can boost natural killer cells by 50%” – Dr. Qing Li, Forest Medicine Expert
