The Psychological Connection
5.5 Physiological vs Psychological Stress
While most of the time we think about stress in a negative way, some stress is adaptive and can even give us an edge. Part of the stress reaction involves the secretion of hormones, which in turn will stimulate the cardiovascular system, which includes your heart. In this way, the right amount of stress may release hormones and increase our ability to focus better on an exam or to quickly maneuver our car when we are trying to avoid an accident. Most stressors in our daily life are psychological in nature—dating, exams, presentations, and deadlines, so the adrenaline and cortisol (i.e., stress hormones) released into the bloodstream do not get burned off. These types of psychological stressors can initiate an over-activation with a tendency to make the stress response worse. So, a response to an environmental stressor may start as fear and turn into a panic attack.
Acute vs Chronic Stress

One of the goals of our body is to maintain stability (i.e., homeostasis). We can, therefore, define stress as an actual or perceived threat capable of throwing our homeostasis off balance. Stress exposure starts the responses. When a person is exposed to prolonged stress, overload may occur. When the stress response is triggered too often and/or remains active too long, it can cause “wear and tear” on the body from lowering your immune system and bone density, to hypertension, to heart attack.
There are two different types of stressors that we typically encounter. Acute stressors are observable stressful events that are time-limited such as an upcoming test or a family gathering. An acute stressor brings activation to our neuroendocrine system and makes us ready to act (i.e., “fight or flight”). Remember that pumped up feeling you got the last time you were getting ready to give a speech in front of the class? Chronic stressors, in contrast, are persistent demands on you; they are typically open-ended, using up your resources in coping but not having any resolution. Here is a short article and podcast on stress effects on health and suggestions for stress preventive activities.
A chronic illness, poverty, and racial discrimination are all examples of chronic stressors. Prolonged stress can lead to an eventual breakdown, causing one to be unable to take care of oneself or work. A number of recent studies have shown that lower socioeconomic status is associated with higher stress load. In addition, perceptions of racism can serve as a chronic social stressor for ethnic minorities and can, in part, explain some of the health issues of African Americans and other ethnic minority groups in the US and other countries.
Everyday Hassles

Robert Service, a Canadian Poet, cautioned, “Be master of your petty annoyances and conserve your energies for the big, worthwhile things. It isn’t the mountain ahead that wears you out—it’s the grain of sand in your shoe.”
In addition to many stressors in our lives being psychological and chronic in nature, we should pay attention to everyday hassles, which can be as harmful, if not more harmful than life-changing events. Everyday hassles may include things like worrying about one’s weight, having too much work with too little time, or a stressful commute to school or work. Major life changes usually bring about more hassles, which may lead to more physical stress symptoms.
In summary, stress can be adaptive—in a fearful or stress-causing situation, we can run away to save our lives, or we can concentrate better on a test. Biologists might even say it is necessary. But, stress can also be maladaptive. This is especially true if it is prolonged (i.e., chronic stress) because it increases our risk of illness and health problems. Thus, reducing stress, especially prolonged stress, is essential to healthcare. This video explains the effects of daily hassles on our health.
