In an increasingly technology-driven world, our bodies undergo profound transformations that go well beyond the obvious effects on our posture and musculature. This book explores how devices actually shape our bodies, from hormonal systems to brain organization, immune function, and metabolism. Understanding the ways in which devices affect our bodies has become imperative in today's society. Backed by a wealth of scientific research spanning the past two decades, this book offers a comprehensive analysis of the disorders and shifts that have emerged as a result of technology: from addictions and pathologies to newfound needs. Moreover, it unveils the societal changes brought about by new technologies. The book was written with both scholars of philosophy, anthropology, medicine, technology, human sciences and natural sciences and general readers in mind.
