It is only fitting to express gratitude to the many experts and researchers who have devoted countless hours to enhancing our understanding of the sauna. Their work has transformed what was once regarded as a cultural tradition into a scientifically validated tool for health, resilience, and longevity. I welcome a healthy dose of scepticism—it's beneficial. Therefore, I encourage you to investigate the background behind each claim, whether from the book or about saunas in general.
