U.S. businesses play a crucial role in promoting healthy lifestyles since they are the principal source of health insurance in the United States, providing health benefits for about 149 million nonelderly people. Consequently, employers bear a massive share of the nation’s health care costs and have unique influence over their employees’ lifestyle choices. Moreover, a productive workforce is key to business success, so healthy employees are a major business concern. As health care costs continue to soar, businesses are looking for ways to save on health care any way they can. Companies are increasingly turning to workforce wellness programs, which research shows can effectively lower health care costs and improve workforce productivity.
