Jeremy McCarthy, director of global spa development and operations at Starwood Hotels and Resorts, has published a new book titled The Psychology of Spas & Wellbeing: A guide to the Science of Holistic Healing.

The book draws on both McCarthy's 20-year career as a spa operator and his studies of applied positive psychology (APP). McCarthy recently received a master's degree in APP from the University of Pennsylvania in Philadelphia, US.

Exploring the science behind the claims of the spa industry, the new book looks for possible applications to enhance the impact of a spa as a centre for holistic healing.

It is targeted at spa and wellness professionals looking to educate themselves on the science behind the treatments and services being offered - as well as to improve their understanding about the holistic approach to wellness.

McCarthy said: "The Psychology of Spas and Wellbeing is the culmination of years of research in psychology, positive psychology, and the science of holistic wellbeing.

"The spa industry markets itself as offering holistic wellness through a variety of services intended to enhance wellbeing across body, mind and spirit."
