Stress has a powerful impact on various aspects of your life—not only can it affect your mood, energy level, relationships, and work performance, stress can also cause and exacerbate a wide variety of health conditions.
Persistent reactions to stress can lead to serious health problems, including:
If you have ever spent time with someone who is suffering from severe stress, you’ll understand the ways it can affect how you two relate—the anger, irritation, and frustration that comes from stress can easily influence the things we say and how we treat one another.
In a 2009 study, researchers Neff and Karney examined the lives of newlyweds and found that during periods of high perceived stress, people tended to react more intensely to the normal ups and downs in a relationship —creating, in effect, problems where there weren’t any. When we perceive high amounts of stress, we tend to blame or take out our frustrations on others. This can create real damage in a relationship, affecting communication  and trust, which then becomes another source of stress.

Stress can lead to burnout—emotional exhaustion, depersonalization, and a sense of low personal accomplishment that leads to decreased effectiveness at work. For example, in a recent study from the prestigious journal Archives of Internal Medicine, over 45% of practicing physicians are experiencing at least one symptom of burnout, which can lead to dangerous mistakes and lapses in judgment that could affect a patient’s health. A similar pattern of burnout is undoubtedly found in many other occupations, demonstrating the importance of stress management in the workplace.
