A new study shows that physical activity programs at work may benefit employees’ mental health and well-being. In the study, published in the journal Current Psychology, researchers at Deakin University in Australia enrolled almost 3,000 workers in a 50-day online workplace wellness program which stressed walking and other physical activity during the work day. They calculated that participants had between 10 and 20 percent lower rates of anxiety, depression and stress at the end of the 50 days. A recent survey showed employee stress, worry, anger and sadness are at record high levels. These findings suggest employers could use physical activity programs to improve the mental health of their employees in less than two months.
