This comprehensive book by Dr. Amdy Diene examines the complex relationship between digital technology and human well-being in the modern era. Published in 2024, the work provides an evidence-based exploration of how smartphones and social media affect physical, mental, and social health while offering practical strategies for maintaining digital wellness. The book is structured across ten chapters, each addressing distinct aspects of the digital health landscape:

The opening chapter establishes the context of our "always-connected culture," acknowledging both the benefits of increased connectivity and access to health resources while introducing the challenges of constant digital engagement. The author takes a balanced approach, avoiding both techno-optimism and digital alarmism.

Physical health consequences are extensively covered in Chapter 2, examining issues like "text neck," digital eye strain, and sleep disruption from blue light exposure. The author provides a detailed analysis of how prolonged device use affects musculoskeletal health and circadian rhythms, supported by current research.

Chapter 3 delves into the neuroscience of digital addiction, explaining how dopamine-driven feedback loops and variable reward schedules create compelling engagement patterns. The author provides a sophisticated analysis of the neurobiological mechanisms underlying smartphone addiction.

The relationship between social media and mental health is thoroughly explored in Chapter 4, examining both positive aspects (support networks, resource access) and negative impacts (depression, anxiety, loneliness). The author pays particular attention to how different patterns of social media use can either enhance or diminish psychological well-being.

Cognitive impacts are analyzed in Chapter 5, investigating how digital technology affects attention spans, information processing, and deep thinking. The other chapters will be described throughout the book.
