This book seeks to understand young men's mental health by going to the places and spaces where they spend their time. It is essential reading for researchers, clinicians, policymakers and members of the general public who care about men's wellbeing. Each chapter focuses on the contemporary nexus between masculinities and health, encompassing alcohol, gambling, sport, gaming, social media, pornography, and dating apps, to explore how and why these areas are central to young men's lives and their health. Addressing the present day 'crisis of masculinity', this edited volume comprises a series of up-to-date reviews to emphasise strength-based, healthy masculinities in young men's mental health. It seeks to understand and engage with research, policy, and practice to co-design effective interventions supporting young men, presenting a clear agenda to direct future efforts.
