Abstract
The issue of employee productivity has become a major concern for companies. Inefficiency can occur at every stage of production either as poor design, worker limitation, or other factors. It is generally assumed that a healthy worker is more productive than an unhealthy worker. As early as 1776 Adam Smith observed and published in The Wealth of Nations that poor worker health was a detriment to industrial productivity. The objective of this article is to review the literature documenting the gain or loss of productivity related to the health of workers, as well as any lifestyle management strategies that can be used to improve employee health and productivity. The impact of employee obesity, smoking, physical activity, sleep, and behavioral health on productivity will be explored. By identifying and addressing health risks that impair worker performance, lifestyle medicine professionals can demonstrate a significant return on investment by creating a healthier and more productive work force.
