Faculty of Education School of Exercise Science, Physical and Health Education PE 142 Human Wellness and Potential Course Notes - Chapter 2 From: Hales, Dianne and Lauzon, Lara (2007). An Invitation to Health, First Canadian Edition. Toronto: Thomson Nelson. Chapter 2 Personal Stress Management What is Stress? An external force that causes a person to become tense or upset, as the internal  state of arousal As the physical response of the body to various demands.  Dr. Hans Selye defined  stress  as “the nonspecific response of the body to any  demand made upon it.” o the body reacts to  stressors  - the things that upset or excite us - in the  same way, regardless of whether they are positive or negative.  Stress can be acute, episodic, or chronic, depending on the nature of the  stressors or external events that cause the stress response.  o Acute or short-term stressors can range from a pop quiz to a bomb threat  in a crowded stadium and trigger a brief but intense response to a  specific incident.  o Episodic stressors like monthly bills or mid-term and final exams cause  regular but intermittent elevations in stress levels.  o Chronic stressors include everything from rush-hour traffic to a learning  disability to living with an alcoholic parent or spouse.  Not all stressors are negative.  o Selye coined the term  eustress  for positive stress in our lives ( eu  is a  Greek prefix meaning “good”). Eustress challenges us to grow, adapt,  and find creative solutions in our lives.  o Distress  refers to the negative effects of stress that can deplete or even  destroy life energy.  What Causes Stress? General adaptation syndrome (GAS) , developed by Hans Selye. o Our bodies constantly strive to maintain a stable and consistent  physiological state, called  homeostasis

o Stressors, whether in the form of physical illness or a demanding job,  disturb this state and trigger a non-specific physiological response.  o The body attempts to restore homeostasis by means of an  adaptive  response Selye’s general adaptation syndrome, consists of three distinct stages: 1. Alarm.  When a stressor first occurs, the body responds with changes that temporarily  lower resistance. Levels of certain hormones may rise; blood pressure may increase  (see Figure 2-1) page 30. The body quickly makes internal adjustments to cope with  the stressor and return to normal activity. 2.
