Psychophysiological Disorders and Stress

The genesis of psychosomatic disorders happens during sustained stressful situations. In this regard, sustained tension can affect several body systems. Continue reading to find out more about the connection between psychophysiological disorders and stress.
Psychophysiological Disorders and Stress

Last update: 22 February, 2024

Today’s article is about psychophysiological disorders and stress. Who hasn’t been under that state of overactivation called stress? Even though it’s always associated with an unpleasant sensation, it’s useful.

Stress could have counterproductive consequences when it’s high in intensity or continuity. In fact, the relationship between stress and mental disorders is a subject of many studies; they discovered that many of these begin with stress.

What’s stress?

Professor J. Carrobles (1991) from the Autonomous University of Madrid defines stress as:

“Stress is a state of sustained overactivation experienced by a person in different situations considered excessive. They occur under conditions of scarce control and social support resources in a subject.”

Nevertheless, it’s necessary to unravel the term stress, as it has two meanings. You can break it down into “distress” and “eustress”.

  • Distress (“dis-” = “altered, inadequate”) – This is when the stress is pathological and results in altered responses due to excessive situations.
  • Eustress (“eus-” = “adequate, good”) – This one refers to adequate and necessary stress. It may be insufficient, optimal, or excessive and it could lead to distress.

What’s the difference between stress and anxiety?

To understand the relationship between stress and psychophysiological disorders, you must differentiate it from anxiety. This is because the body’s response is often similar.

Anxiety is about danger, either real or so interpreted by a given person. This doesn’t happen in stressful situations because they don’t have to be unpleasant or dangerous. Unless a person perceives a situation as dangerous, they won’t usually run away as it’s easier to deal with it.

In the face of anxiety, the typical response is to escape. This position remains through the anxiety-avoidance-anxiety mechanism. If you perceive something as dangerous or harmful, it’s logical for you to have the typical response to flee. If it’s dangerous, you’ll need some tools to defend yourself from such danger. And people don’t usually have such feelings of self-efficacy. They perceive something as dangerous because they’re unable to fight it.

In addition, for stress to produce harmful effects, it must continue over time. In the case of anxiety, even if only for a short period of time, it’s already harmful. Mainly because it can affect the social and emotional functioning of a person in a short time.

The connection between psychophysiological disorders and stress

“Homeostasis” – homo = “return to,” stasis = “balance” – refers to the return to bodily balance. All humans have an internal environment and vital signs and these have a tendency for balance. That is to say, the agency implements actions to solve any imbalances a person might develop.

When you don’t reach homeostasis, you’ll experience stress. If you have to implement conscious strategies because they’re not working automatically, then it’s normal not to reach that state of equilibrium. Instead, you reach “hemokinesis”, a state of imbalance.

The physiological responses of stress

Even though it’s clear that stress can lead to irritability, apathy, anxiety, anguish, and anger, it also leads to physiological or bodily responses that you may not notice. These are very relevant to the relationship between stress and psychophysiological disorders. This is because when you maintain them over time due to the stressful situation, they could lead to certain disorders, some psychosomatic.

The physiological responses to stressful situations are the result of various bodily systems, such as the autonomic nervous system and the central nervous system.

Somatic nervous system

In the physiological response to stress, the somatic system is responsible for the electromyographic response. That’s the electrical activity produced by skeletal muscles, such as eye movements and breathing.

Thus, there may be an increase in blood flow to large muscle groups during stress: back, arms, legs. In addition, there may also be generalized muscular tension.

Autonomic nervous system

The stress responses this system takes over are related to the cardiovascular system: heart rate, blood pressure, and blood flow. They also regulate body temperature, sexual excitement, and electrodermal responses. That is the skin power level and its conductive response. In addition, there’s salivation and gastrointestinal responses.

Therefore, in the face of stress, there may be an increase in your heart rate, renal activity, peripheral vasoconstriction in your hands and feet, and an increase in the blood clotting factor.

Psychophysiological disorders and stress – the central nervous system

As for the responses of the central nervous system, there are electroencephalographic responses and evoked responses.

Finally, there are also responses to stress that come from the endocrine and biochemical systems. These can lead to various hormonal changes and an increase in immunological activity at the beginning, it later decreases.

Bodily systems disabled before stress

As with anxiety, certain body systems are deactivated in response to stress because they’re not useful. Given the specific response of an anxiety attack, these systems either deactivate or reactivate. But, in a sustained situation of stress, they could affect a person’s health.

The influx of blood in the digestive tract goes down, leading to possible problems such as ulcers, colitis, and irritable bowel syndrome. This also occurs with the genito-sexual system, where stress can lead to sexual dysfunctions in arousal, erection, lubrication, and tumescence.

The genesis of psychophysiological disorders due to stress

Psychosomatic disorders are the physiological conditions of psychological origin. Stress is something that, in principle, shouldn’t affect a person’s physical well-being. But it can lead to very unpleasant diseases and their symptoms.

They’re proof of the influence of the “mind” on the well-being of your body. Contrary to what many people think, they always go hand in hand.

As we mentioned above, stress itself isn’t exactly bad. However, when it turns into distress and it shows the following characteristics, chances are it’ll affect your psychophysiological well-being.

Thus, the factors pertaining to stress and psychophysiological disorders are:

  • Frequent or prolonged exposure to stimuli or stressful situations. When people don’t get out of a stressful situation, it’ll only get worse. Not solving things quickly or staying in a stressful environment without being able to avoid it is the first step in developing a psychosomatic disorder.
  • Prolonged activation of the specific pattern of physiological activation of the subject in the face of stress. Each person has a different stress profile, and your physiological activation is different from that of others, as we explained above. Depending on the response, the psychosomatic symptoms will vary.
  • Exaggerated sensitization or activation of the organic system in the face of stress. Once you’re fully in a stressful situation, it’s normal for your body to become sensitive to it. And it’s much easier for you to be stressed.
  • Alteration of the homeostatic regulatory mechanism. Once you reach certain stress levels, it’s easier for alterations to occur. This is because there’s a lower tolerance for the stimuli that cause the problems.
  • Chronic alteration of the functioning of the organic system. Also, the appearance of a stressful or psychophysiological or stressful psychosomatic disorder.

Psychophysiological disorders and stress – auxiliary and palliative resources

Many times, you can’t get out of stressful situations and must maintain them over time. However, many resources can help you reduce stress to avoid the result of the relationship between stress and psychophysiological disorders. 

The resources for sustained stress you can use are:

  • Social network and social support (family, friends, and colleagues). You must pay attention to the scarcity of social resources, deficits in social relationships, and special social conditions. A powerful social and family network is a good factor of protection against the consequences of stress.
  • Activity and physical exercise.
  • Hobbies.
  • Cultural activities.
  • Include fruit and vegetables that are rich in tryptophan in your diet as they act as antidepressants.

Thus, the relationship between stress and psychophysiological disorders seems clear. Thus, to avoid losing your well-being in the face of stressful situations you can avoid, you must take charge and allow your body to reach homeostasis beyond a period of stress.
