Stress is part of our life
Stress is anything that alters your natural balance. When stress is present, your body and your mind must attend to it in order to return you to balance. Your body reacts to stress by releasing hormones that help you cope with the situation. That in turn takes energy away from the other functions of your brain, like concentrating, or taking action. There are two different sources of stress: external triggers, like getting a poor grade or breaking up with your girlfriend/boyfriend, and internal triggers, like placing high expectations on yourself.
Stress is a part of everyday life. There are many instances when stress can be helpful. A fire alarm is intended to cause the stress that alerts you to avoid danger. The stress created by a deadline to finish a paper can motivate you to finish the assignment on time. But when experienced in excess, stress has the opposite effect. It can harm our emotional and physical health, and limit our ability to function at home, in school, and within our relationships. But the good news is that, since we are responsible for bringing about much of our own stress, we can also do much to manage stress by learning and practicing specific stress-reduction strategies.
