Punch out on a positive.
A 2012 study in the Academy of Management Journal found that women who wrote down three positive events—career related or otherwise—at the end of each workday, plus a brief reason why they thought each good thing had happened ("My boss complimented my work because she appreciates the effort I put in"), not only reported lower levels of stress but also experienced a reduction in physical complaints such as headaches, back pain and muscle tension. "This simple intervention works against our impulse to focus on the rough spots in our day," says study coauthor Joyce Bono, PhD, a professor of management at the University of Florida. "It gives you the power to reframe your mood—and improve your health."
