The lives of circus artists can be mentally and physically demanding. Circus Psychology: An Applied Guide to Thriving Under the Big Top is an evidence-based guide to nurturing the mental health of circus artists while enabling them to perform at the peak of their capacities.

The first section introduces general mental health concepts, provides insight into the mental health of circus artists, the stress process, and the role of psychological resilience and perfectionism in mental health. The second section offers insight into motivation and engagement in circus, the features of a psychologically safe circus environment, and advice on psychologically supportive talent development environment. The final section explains, applies, and provides practice material for mental skills, including goal setting, self-talk, mental imagery, arousal regulation, and visual anticipation. Written by Dr Fleur van Rens, a circus artist and lecturer in sport psychology, this book is an essential resource for those passionate about the mental health of amateurs and professionals in the circus industry.
