The field of subjective well-being (SWB), or happiness, has become a thriving area of science, with over 10,000 publications per year on the topic in recent years. Discoveries about the causes and processes involved in SWB range widely, from culture to biology to circumstances, providing instructors an opportunity to draw broadly on concepts from psychology. New research shows that high SWB not only feels good but is also good for one's health and social relationships. In addition to providing a platform for discussions about what constitutes a life well-lived, teaching about SWB is an excellent opportunity to emphasize scientific research and to dispel misconceptions. Besides traditional lectures, the area offers opportunities for learning exercises and self-exploration.
