This introduction chapter explores the multifaceted ways in which the concept of wellbeing can be both understood and consumed. Wellbeing has increased cultural capital because there is growing recognition that wellbeing is valuable, not only because it feels good but also because wellbeing is central to achieving greater productivity, performance success, improved health, longevity, resilience, personal growth and quality of life. Compared to those with low wellbeing, individuals with high wellbeing have better physical health, stronger immune systems, live longer, have fewer sleep problems, lower levels of burnout, greater self-control, better self-regulation and coping skills, are more prosocial, have more satisfying relationships and are more cooperative. Similarly, informed by the general literature and a small but growing body of knowledge about athlete wellbeing, those involved in performance sport are beginning to recognize the multilevel significance of wellbeing for athletes’ health, development and performance as well as their lives beyond and after sport. Here, we present the departure point for the forthcoming chapters that explore this fascinating yet deeply complex element of human thriving.
