In this talk, I will discuss my work on how circadian rhythms shape people at work, as well as how to shape their circadian rhythms. In this discussion of my research program, I will briefly review my published research on how circadian rhythms shape unethical behavior and charismatic leadership. Then I will discuss ongoing work which extends these concepts beyond just work experiences, focusing on how circadian rhythms shape the beneficial effects of passive and active recovery activities. I will share fresh results of an unpublished laboratory experiment in which my coauthors and I manipulated chronotype assignment (larks versus owls), time of day (early in the morning versus late at night), and recovery activity (passive relaxation versus active physical exercise). We find support for half of our model, such that larks get more recovery from exercise conducted in the morning, and owls get more recovery from exercise conducted at night (but time of day did not create differential benefits to relaxation for larks versus owls). Following this, I will discuss how organizations may shape the circadian rhythms of their employees. I will briefly discuss my published paper examining how wearing blue light filtering glasses at night can help improve sleep and work outcomes.
