Book excerpt: A global multidimensional concept, well-being is an important measure that is closely associated with quality of life. This book examines well-being concepts and measurements, related health theories and correlates of well-being, as well as gender and geographical differences. The authors explore the evidence on well-being policies, programs, and health interventions, in addition to issues of health advocacy, self-care, and healthy aging. They also examine global wellness perspectives in the context of planetary challenges and decolonization. As the authors share their unique perspectives, they bring to the fore the integration of cross-cutting themes of gender, human rights, social and environmental justice/equity and inclusivity, health promotion/settings, and healthy public policy. This book explores the diversity of philosophical and methodological perspectives on wellness and well-being. It further contextualizes the lived experience of the dimensions of well-being as experienced by the contributors across different regions of the globe.
