With over 1,560 references and hundreds of clear visuals across 544 pages, the book acts as both a coffee‑table compendium and a practical manual for daily life.

The handbook is written by a trio of experts: Olli Sovijärvi, M.D., Teemu Arina, a digitalization specialist, and Jaakko Halmetoja, a nutrition expert. Sovijärvi brings authoritative medical and holistic health insight. After earning his Licentiate in Medicine at the University of Helsinki in 2006, he serves in diverse healthcare roles—including emergency and primary care in roughly 50 Finnish clinics—and works at a holistic nutrition and wellness clinic with Finland’s only trace‑element laboratory. He further expands his holistic perspective with studies in integral theory (psychology and philosophy) at John F. Kennedy University in 2010–2011. Today he focuses on creating scientific content, consulting wellness‑tech firms, and leading workshops on biohacking, performance, and gut health.

The text blends Sovijärvi’s medical rigor with Arina’s tech‑driven approach and Halmetoja’s nutrition expertise, producing a holistic toolkit for healthspan enhancement. It skillfully balances ancestral wisdom and modern innovations—cold exposure, nutrient timing, mindfulness—backed by peer‑reviewed research and practical applications .

Overall, “Biohacker’s Handbook” presents itself as a definitive atlas for anyone aiming to take control of their body and mind, squeeze out peak performance, and future‑proof their wellbeing in a fast‑paced world.
