Health Professional Caregivers. Caregiving among the health professionals is also a high risk factor for stress. One 2000 study, for example, found that registered nurses with low job control, high job demands, and low work-related social support experienced very dramatic health declines, both physically and emotionally.

Anxiety Disorders

People who are less emotionally stable or have high anxiety levels tend to experience specific events as more stressful than others. Some experts describe an exaggerated negative response to stress as "catastrophizing" the event (turning it into a catastrophe). Nevertheless, a 2003 study of patients with anxiety disorder did not find any differences in actual physical response to stress (heart rate, blood pressure, release of stress hormones) compared to people without anxiety.

Lacking a Social Network

The lack of an established network of family and friends predisposes one to stress disorders and stress-related health problems, including heart disease and infections. And, a 2000 study reported that older people who maintain active relationships with their adult children are buffered against the adverse health effects of chronic stress-inducing situations, such as low income or lower social class. One study suggested this may be because people who live alone are unable to discuss negative feelings and so relieve their stress.

Many studies suggest that having a pet helps reduce medical problems aggravated by stress, including heart disease and high blood pressure.
