The Science of Yoga: The Risks and the Rewards is a 2012 non-fiction book by William Broad. 
Synopsis.
Broad investigates the veracity of health claims associated with yoga as exercise, using scientific methods. Broad, who has practiced yoga since 1970, systematically examines assertions that yoga can prevent heart disease, reverse aging, alleviate pain, and enhance mental well-being.
The book reviews existing scientific literature, evaluating the quality and methodology of studies related to each claim. Broad identifies evidence supporting some benefits of yoga as exercise, such as reducing anxiety and improving mood, while noting areas where evidence is lacking, such as in weight loss. He also explores the potential of yoga to influence biological aging processes.
Broad examines the historical roots of yoga in ancient India. His research includes visits to libraries, interviews with historians, and examination of archival materials, revealing the diverse practices and beliefs associated with traditional yoga as a spiritual practice. This historical perspective contrasts with the modern perception of yoga as primarily a wellness activity in Western societies.
