The Sauna Academy Guide to the Art and Science of Sauna Aufguss Rituals, Techniques, and Professional Practice in Modern Sauna Culture by Dr. Karsten Gröning The Sauna Academy Guide to the Art and Science of Sauna Aufguss is the most comprehensive English-language reference on the philosophy, physiology, and professional practice of the sauna ritual known as the Aufguss . Written by Dr. Karsten Gröning , this richly illustrated training compendium combines scientific precision with cultural depth and practical guidance. Across more than 130 chapters and figures, the book explores the historical origins of sweat rituals worldwide – from Scythian steam tents and Roman thermae to the Finnish sauna, Russian banja, and Mesoamerican temazcal – and connects them to the modern European Aufguss tradition. Readers will gain a full understanding of the physical, physiological, psychological, and cultural foundations that make the Aufguss such a unique and health-promoting experience. Key topics include: The physics of heat transfer and the biological response of the human body during an Aufguss. - Thermophysiological and psychological effects of steam, scent, and ritual structure. - Detailed requirements for sauna cabins, stoves, safety, and hygiene . - Professional fanning techniques, aroma applications, and specialty Aufgüsse (salt, honey, dairy, menthol, coffee, tea, and more). - Educational and psychological competencies for sauna masters and trainers. - Legal, operational, and quality standards for professional sauna management. - Insights into future trends in health-oriented and experiential sauna culture. This guide serves as both a training manual and reference work for sauna professionals, spa operators, wellness educators, and anyone passionate about understanding and performing the Aufguss responsibly, creatively, and scientifically. “Each Aufguss is more than heat and steam – it is the experience of connection between human beings, nature, and culture.” — Dr. Karsten Gröning
