As pointed out by Hyland, Lee, and Mills (2015), the most prominent effect of mindfulness is a significant decrease in experienced stress levels, and one of the most popular mindfulness interventions is mindfulness-based stress reduction. When it comes to psychological stress, desirable outcomes are both expected and documented for employees who adopt a mindful approach to work. But how are these beneficial effects happening, exactly?Hyland, Lee, and Mills did not elaborate on the theoretical frameworks that may be useful to academic researchers in organizational psychology aiming to better understand this phenomenon, nor did they discuss how examining mindfulness through the lens of occupational stress theory could lend new insights and inform new interventions. Indeed, from a strictly academic viewpoint, we have limited empirical evidence demonstrating how and why mindfulness "works," especially pertaining to the occupational stress process as we understand it in organizational psychology. Thus, the purpose of my commentary is to supplement the focal article with an additional discussion of mindfulness in the context of several existing occupational stress theories.In general, occupational stress research relies on a stressor-strain model whereby stressors (environmental stimuli) lead to strains (maladaptive responses to stressors). There are several points of entry in this process whereby mindfulness may exert influence. First, mindfulness may alter initial perception and appraisal of stressors to begin with. Second, after the stress process has begun, mindfulness may offer reserves of personal resources and promote adaptive coping. Finally, if strain responses do ultimately arise, it may aid in one's self-regulation of them.What follows is a concise discussion of each of the points of entry noted above and the corresponding theoretical frameworks that may be used to support empirical investigations. Notably, I focus on the western interpretation of the construct of mindfulness. Furthermore, although neurobiological
