A study (#1268) being presented this morning as a poster reports that there is a bidirectional relationship between stress and poor sleep.
Results show that higher habitual stress is associated with reported shorter sleep duration, poorer sleep quality, and daytime functioning impairments. Conversely, daytime functioning impairments and shorter sleep duration demonstrated a predictive relationship with habitual stress complaints.
In February the Sleep Education Blog reported that stress related to the struggling economy can have a negative impact on sleep. On SleepEducation.com the American Academy of Sleep Medicine describes how job stress can affect sleep.
