Abstract
Today, the terms precision health, precision medicine, and even precision wellness are peppering the literature and discourse around the agendas of providing better health and wellness to a growing aging population who also is experiencing a rapid rise in chronic and noncommunicable diseases. This chapter tries to uncover some of the mystique around precision wellness by first highlighting how it differs from related terms precision medicine and precision health and then by presenting an optimization model for precision wellness which leverages the tools and technologies of the Internet of Things (IoT). Finally, co-design principles including gamification techniques to enable sustained, strong user-engagement are also discussed.
