Kuni Style Enzyme Spa English Information

Aloha, I’m Irminne Van Dyken, MD from Out of the Doldrums. During a recent trip to Japan, I experienced something unusual: an enzyme bath, known as kōso-buro. Instead of soaking in water, you lie in a bed of warm fermented rice bran and cedar sawdust. The heat is not produced by electricity. It’s generated by microbial fermentation. In this video I explain the history of Japanese enzyme baths, how they were developed in Hokkaido, and what science may explain their effects. We’ll look at the microbiology behind the fermentation process, the role of bacteria like Bacillus subtilis, and how fermentation produces compounds such as enzymes, antioxidants, and biosurfactants. In the final part of the video, I have the opportunity to speak with enzyme bath master Kuniko Iida, who runs Kuni Style Enzyme Spa in Tokyo. She shares her perspective on the tradition, preparation, and philosophy behind these baths, and it ended up being one of my favorite parts of the experience. Here is the link to the Kuni Style Enzyme Spa, run by the fabulous Kuniko Iida: Website: https://www.kunistyle-spa.com/english-information/ Instagram: https://www.instagram.com/kunistyle_ginza/ I also explore the potential health effects that are often discussed with enzyme baths, including: • skin hydration and barrier repair • possible benefits for eczema, dermatitis, and psoriasis • collagen production and skin aging • the skin microbiome and immune signaling • the physiological effects of heat exposure Much of what we know about the benefits of passive heat comes from sauna research, so I also discuss what that research tells us about circulation, inflammation, and metabolic health. While enzyme baths themselves are not yet widely studied in clinical trials, the underlying mechanisms — fermentation biology, microbial metabolites, and heat therapy — are areas of active scientific research. If you’ve ever tried an enzyme bath, I would love to hear about your experience. Cherish your health always, and aloha.
