The link between high stress situations and elevated blood pressure makes good intuative sense and is well established in the medical literature. However, new research published in The Journal of Occupational and Environmental Medicine shows that blood pressure elevations related to work stress don't go away when workers go home.
In fact, the elevations persist throughout the day, and continue long after the stressful events of the work day have passed. Most strikingly, researchers found that stressful work conditions lead to higher blood pressure even during sleep. The study suggests that the most important aspect of job stress, in terms of its effects on blood pressure, is a feeling of having little or no control while in the office. "Low job control" workers had the most significant overall elevations in blood pressure, and these elevations persisted the longest.
