In psychology, stress is a feeling of emotional strain and pressure. [1] Stress is a form of psychological discomfort and mental discomfort. Small amounts of stress may be beneficial, as it can improve athletic performance, motivation and reaction to the environment. Excessive amounts of stress, however, can increase the risk of strokes, heart attacks, ulcers, and mental illnesses such as depression [2] and also aggravate pre-existing conditions.

Contents

Psychological stress can be external and related to the environment, [3] but may also be caused by internal perceptions that cause an individual to experience anxiety or other negative emotions surrounding a situation, such as pressure, discomfort, etc., which they then deem stressful.

Hans Selye (1974) proposed four variations of stress. [4] On one axis he locates good stress (eustress) and bad stress (distress). On the other is over-stress (hyperstress) and understress (hypostress). Selye advocates balancing these: the ultimate goal would be to balance hyperstress and hypostress perfectly and have as much eustress as possible. [5]

The term "eustress" comes from the Greek root eu- which means "good" (as in "euphoria"). [6] Eustress results when a person perceives a stressor as positive. [7] "Distress" stems from the Latin root dis- (as in "dissonance" or "disagreement"). [6] Medically defined distress is a threat to the quality of life. It occurs when a demand vastly exceeds a person's capabilities. [7]

Causes

Neutrality of stressors

Stress is a non-specific response. [5] It is neutral, and what varies is the degree of response. It is all about the context of the individual and how they perceive the situation. Hans Selye defined stress as “the nonspecific (that is, common) result of any demand upon the body, be the effect mental or somatic.” [5] This includes the medical definition of stress as a physical demand and the colloquial definition of stress as a psychological demand. A stressor is inherently neutral meaning that the same stressor can cause either distress or eustress. It is individual differences and responses that induce either distress or eustress. [8]

Types of stressors

A stressor is any event, experience, or environmental stimulus that causes stress in an individual. [9] These events or experiences are perceived as threats or challenges to the individual and can be either physical or psychological. Researchers have found that stressors can make individuals more prone to both physical and psychological problems, including heart disease and anxiety. [10]

Stressors are more likely to affect the health of an individual when they are "chronic, highly disruptive, or perceived as uncontrollable". [10] In psychology, researchers generally classify the different types of stressors into four categories: 1) crises/catastrophes, 2) major life events, 3) daily hassles/microstressors, and 4) ambient stressors. According to Ursin (1988), the common factor between these categories is an inconsistency between expected events ("set value") and perceived events ("actual value") that cannot be resolved satisfactorily, [11] which puts stress into the broader context of cognitive-consistency theory. [12]

Crises/catastrophes

This type of stressor is unforeseen and unpredictable and, as such, is completely out of the control of the individual. [10] Examples of crises and catastrophes include: devastating natural disasters, such as major floods or earthquakes, wars, pandemics, etc. Though rare in occurrence, this type of stressor typically causes a great deal of stress in a person's life. A study conducted by Stanford University found that after natural disasters, those affected experienced a significant increase in stress level. [10] Combat stress is a widespread acute and chronic problem. With the rapid pace and the urgency of firing first, accidental killings of friendly forces (or fratricide) may occur. Prevention requires stress reduction, emphasis on vehicle and other identification training, awareness of the tactical situation, and continual risk analysis by leaders at all levels. [13]

Major life events

Common examples of major life events include: marriage, going to college, death of a loved one, birth of a child, divorce, moving houses, etc. These events, either positive or negative, can create a sense of uncertainty and fear, which will ultimately lead to stress. For instance, research has found the elevation of stress during the transition from high school to university, with college freshmen being about two times more likely to be stressed than final year students. [14] Research has found that major life events are somewhat less likely to be major causes of stress, due to their rare occurrences. [10]

The length of time since occurrence and whether or not it is a positive or negative event are factors in whether or not it causes stress and how much stress it causes. Researchers have found that events that have occurred within the past month generally are not linked to stress or illness, while chronic events that occurred more than several months ago are linked to stress and illness [15] and personality change. [16] Additionally, positive life events are typically not linked to stress – and if so, generally only trivial stress – while negative life events can be linked to stress and the health problems that accompany it. [10] However, positive experiences and positive life changes can predict decreases in neuroticism. [16] [17]

Daily hassles/microstressors

This category includes daily annoyances and minor hassles. [10] Examples include: making decisions, meeting deadlines at work or school, traffic jams, encounters with irritating personalities, etc. Often, this type of stressor includes conflicts with other people. Daily stressors, however, are different for each individual, as not everyone perceives a certain event as stressful. For example, most people find public speaking to be stressful, but someone who has experience with it will not.

Daily hassles are the most frequently occurring type of stressor in most adults. The high frequency of hassles causes this stressor to have the most physiological effect on an individual. Carolyn Aldwin, Ph.D., conducted a longitudinal study on older men (mean age ca. 66 years at the time of first stress assessment) at the Oregon State University that examined the perceived intensity of daily hassles on an individual's mortality. Aldwin's study concluded that there is a strong correlation between individuals who rate their hassles as very intense and a high level of mortality. One's perception of their daily stressors can have a modulating effect on the physiological impact of daily stressors. [18]

There are three major psychological types of conflicts that can cause stress.

  • The approach-approach conflict, occurs when a person is choosing between two equally attractive options, i.e. whether to go see a movie or to go see a concert. [10]
  • The avoidance-avoidance conflict, occurs where a person has to choose between two equally unattractive options, for example, to take out a second loan with unappealing terms to pay off the mortgage or to face foreclosure on one's house. [10]
  • The approach-avoidance conflict, [10] occurs when a person is forced to choose whether or not to partake in something that has both attractive and unattractive traits – such as whether or not to attend an expensive college (meaning taking out loans now, but also meaning a quality education and employment after graduation).

Travel-related stress results from three main categories: lost time, surprises (an unforeseen event such as lost or delayed baggage) and routine breakers (inability to maintain daily habits). [19]

Ambient stressors

As the name implies, these are global (as opposed to individual) low-grade stressors that are a part of the background environment. They are defined as stressors that are "chronic, negatively valued, non-urgent, physically perceptible, and intractable to the efforts of individuals to change them". [20] Typical examples of ambient stressors are pollution, noise, crowding, and traffic. Unlike the other three types of stressor, ambient stressors can (but do not necessarily have to) negatively impact stress without conscious awareness. [20]

Organisational stressors

Studies conducted in military and combat fields show that some of the most potent stressors can be due to personal organisational problems in the unit or on the home front. [21] Stress due to bad organisational practices is often connected to "toxic leadership", both in companies and in governmental organisations. [22]

Stressor impact

Life events scales can be used to assess stressful things that people experience in their lives. One such scale is the Holmes and Rahe Stress Scale, also known as the Social Readjustment Rating Scale, or SRRS. [23] Developed by psychiatrists Thomas Holmes and Richard Rahe in 1967, the scale lists 43 stressful events.

To calculate one's score, add up the number of "life change units" if an event occurred in the past year. A score of more than 300 means that individual is at risk for illness, a score between 150 and 299 means risk of illness is moderate, and a score under 150 means that individual only has a slight risk of illness. [10] [23]

The SRRS is used in psychiatry to weight the impact of life events. [24]

Measurement

Modern people may attempt to self-assess their own "stress-level"; third parties (sometimes clinicians) may also provide qualitative evaluations. Quantitative approaches such as Galvanic Skin Response [25] or other measurements giving results which may correlate with perceived psychological stress include testing for one or more of the several stress hormones, [26] for cardiovascular responses, [27] or for immune response. [28] There are some valid questionnaires to assess stress level such as, Higher Education Stress Inventory (HESI) is a valid questionnaire used in many communities for assessment the stress level of college students. [29] [30] There are many (psycho-)physiological measurement methods that correlate more or less well with psychological stress (mental or emotional) and are thus used as a possible indicator. [31] [32] [33] [34] [35] [36] [37] [38] [39]

In the physiological domain of oculomotor function alone, several physiological responses are suspected to detect different stress situations in a person-specific and objective manner (not by means of a survey). For example, via eye movement and gaze behavior, [40] [41] [42] via pupil behavior [43] [44] [45] [46] and via eyelid blink behavior (Blinking). [47] [48] [40] [49] [50]

Physical effects

To measure the body's response to stress, psychologists tend to use Hans Selye's general adaptation syndrome. This biological model, often referred to as the "classic stress response", revolves around the concept of homeostasis. General adaptive syndrome, according to this system, occurs in three stages:

  1. The alarm reaction. This stage occurs when the stressor is first presented. The body begins to gather resources to deal with the stressor. The hypothalamic-pituitary-adrenal axis and sympathetic nervous system are activated, resulting in the release of hormones from the adrenal gland such as cortisol, adrenaline (epinephrine), and norepinephrine into the bloodstream to adjust bodily processes. These hormonal adjustments increase energy-levels, increase muscle tension, reduce sensitivity to pain, slow down the digestive system, and cause a rise in blood pressure. [51] [52] In addition, the locus coeruleus, a collection of norepinephrine-containing neurons in the pons of the brainstem whose axons project to various regions of the brain, is involved in releasing norepinephrine directly onto neurons. High levels of norepinephrine acting as a neurotransmitter on its receptors expressed on neurons in brain regions, such as the prefrontal cortex, are thought[ by whom? ] to be involved in the effects of stress on executive functions, such as impaired working memory.
  2. The stage of resistance. The body continues building up resistance throughout the stage of resistance, either until the body's resources are depleted, leading to the exhaustion phase, or until the stressful stimulus is removed. As the body uses up more and more of its resources, it becomes increasingly tired and susceptible to illness. At this stage psychosomatic disorders first begin to appear. [52]
  3. The stage of exhaustion. The body is completely drained of the hormones and resources it was depending on to manage the stressor. The person now begins to exhibit behaviors such as anxiety, irritability, avoidance of responsibilities and relationships, self-destructive behavior, and poor judgment. Someone experiencing these symptoms has a much greater chance of lashing out, damaging relationships, or avoiding social interaction at all. [52]

This physiological stress response involves high levels of sympathetic nervous system activation, often referred to as the "fight or flight" response. The response Archived 2012-10-10 at the Wayback Machine involves pupil dilation, release of endorphins, increased heart and respiration rates, cessation of digestive processes, secretion of adrenaline, arteriole dilation, and constriction of veins. [53]

Cancer

Psychological stress does not appear to be a risk factor for the onset of cancer, [54] [55] though it may worsen outcomes in those who already have cancer. [54] Research has found that personal belief in stress as a risk factor for cancer was common in England, though awareness of risk factors overall was found to be low. [56]

Other effects

There is likely a connection between stress and illness. [57] Theories of a proposed stress–illness link suggest that both acute and chronic stress can cause illness, and studies have found such a link. [58] According to these theories, both kinds of stress can lead to changes in behavior and in physiology. Behavioral changes can involve smoking and eating habits and physical activity. Physiological changes can be changes in sympathetic activation or hypothalamic pituitary adrenocorticoid activation, and immunological function. [59] However, there is much variability in the link between stress and illness. [60]

There is some evidence that stress can make the individual more susceptible to physical illnesses like the common cold. "Although chronic (but not acute) stressful events are associated with greater susceptibility, the association between social diversity and colds is not altered after controlling for life events." [61] Stressful events, such as job changes, correlate with insomnia, impaired sleeping, and health complaints. [62] Research indicates the type of stressor (whether it is acute or chronic) and individual characteristics such as age and physical well-being before the onset of the stressor can combine to determine the effect of stress on an individual. [63] An individual's personality characteristics (such as level of neuroticism), [16] genetics, and childhood experiences with major stressors and traumas [17] may also dictate their response to stressors. [63] Stress may also cause headaches. [64]

Chronic stress and a lack of coping resources available or used by an individual can often lead to the development of psychological issues such as depression and anxiety. [65] This is particularly true regarding chronic stressors. These are stressors that may not be as intense as an acute stressor like a natural disaster or a major accident, but they persist over longer periods of time. These types of stressors tend to have a more negative impact on health because they are sustained and thus require the body's physiological response to occur daily. This depletes the body's energy more quickly and usually occurs over long periods of time, especially when such microstressors cannot be avoided (for example: stress related to living in a dangerous neighborhood). Chronic stress may lead to allostatic load, a biological process affecting many physiological systems. For example, studies have found that caregivers, particularly those of dementia patients, have higher levels of depression and slightly worse physical health than non-caregivers. [66]

Studies have also shown that perceived chronic stress and the hostility associated with Type A personalities are often correlated with much higher risks of cardiovascular disease. [67] This occurs because of the compromised immune system as well as the high levels of arousal in the sympathetic nervous system that occur as part of the body's physiological response to stressful events. [68] However, it is possible for individuals to exhibit hardiness  – a term referring to the ability to be both chronically stressed and healthy. [69] Chronic stress can correlate with psychological disorders such as delusions. [70] Pathological anxiety and chronic stress lead to structural degeneration and impaired functioning of the hippocampus. [71]

It has long been believed that negative affective states, such as feelings of anxiety and depression, could influence the pathogenesis of physical disease, which in turn, have direct effects on biological process that could result in increased risk of disease in the end. However, studies done by the University of Wisconsin-Madison and other places have shown this to be partly untrue; although perceived stress seems to increase the risk of reported poor health, the additional perception of stress as something harmful increases the risk even further. [72] [73] For example, when humans are under chronic stress, permanent changes in their physiological, emotional, and behavioral responses are most likely to occur. [16] Such changes could lead to disease. [74] Chronic stress results from stressful events that persist over a relatively long period of time, such as caring for a spouse with dementia, or results from brief focal events that continue to be experienced as overwhelming even long after they are over, such as experiencing a sexual assault.

Experiments show that when healthy human individuals are exposed to acute laboratory stressors, they show an adaptive enhancement of some markers of natural immunity but a general suppression of functions of specific immunity. By comparison, when healthy human individuals are exposed to real-life chronic stress, this stress is associated with a biphasic immune response where partial suppression of cellular and humoral function coincides with low-grade, nonspecific inflammation. [75]

Even though psychological stress is often connected with illness or disease, most healthy individuals can still remain disease-free after confronting chronic stressful events. Also, people who do not believe that stress will affect their health do not have an increased risk of illness, disease, or death. [73] This suggests that there are individual differences in vulnerability to the potential pathogenic effects of stress; individual differences in vulnerability arise due to both genetic and psychological factors. In addition, the age at which the stress is experienced can dictate its effect on health. Research suggests chronic stress at a young age can have lifelong impacts on the biological, psychological, and behavioral responses to stress later in life. [76]

Social impact

Communication

When someone is stressed, many challenges can arise; a recognised challenge being communication difficulties. Here are some examples of how stress can hinder communication.

The cultures of the world generally fall into two categories; individualistic and collectivistic. [77]

These cultural differences can affect how people communicate when they are stressed. For example, a member of an individualistic culture would be hesitant to ask for pain medication for fear of being perceived as weak. A member of a collectivistic culture would not hesitate. They have been brought up in a culture where everyone helps each other and is one functional unit whereas the member of the individualistic culture is not as comfortable asking others for aid. [77]

Language barriers

Language barriers can cause stress, and sometimes this stress adds to language barriers. People may feel uncomfortable with the difficulties caused by differences in syntax, vocabulary, ways of showing respect, and use of body language. Along with a desire for successful social interactions, being uncomfortable with the communication around a person can discourage them from communicating at all, thus adding to the language barrier.

The System 1 – System 2 model of Daniel Kahneman's Thinking, Fast and Slow and others[ who? ] distinguishes between automatic responses, such as those one's native language provides, and a foreign language that requires System 2 work to translate. System 2 can become "depleted" by conscious mental effort, making it more difficult and stressful. [78]

Changes in the home

Divorce, death, and remarriage are all disruptive events in a household. [77] Although everyone involved is affected by events such as these, it can be most drastically seen in children. Due to their age, children have relatively undeveloped coping skills. [79] For this reason a stressful event may cause some changes in their behavior. Falling in with a new crowd, developing some new and sometimes undesirable habits are just some of the changes stress may trigger in their lives. [77]

A particularly interesting response to stress is talking to an imaginary friend. A child may feel angry with a parent or their peers who they feel brought this change on them. They need someone to talk to but it definitely would not be the person with whom they are angry. That is when the imaginary friend comes in. They “talk” to this imaginary friend but in doing so they cut off communication with the real people around them. [77]

Social support and health

Researchers have long been interested in how an individual's level and types of social support impact the effect of stress on their health. Studies consistently show that social support can protect against physical and mental consequences of stress. [80] [81] This can occur through a variety of mechanisms. One model, known as the "direct effects" model, holds that social support has a direct, positive impact on health by increasing positive affect, promoting adaptive health behaviors, predictability and stability in life, and safeguarding against social, legal, and economic concerns that could negatively impact health. Another model, the "buffering effect", says that social support exerts greatest influence on health in times of stress, either by helping individuals appraise situations in less threatening manners or coping with the actual stress. Researchers have found evidence to support both these pathways. [82]

Social support is defined more specifically as psychological and material resources provided by a social network that are aimed at helping an individual cope with stress. [83] Researchers generally distinguish among several types of social support: instrumental support – which refers to material aid (e.g., financial support or assistance in transportation to a physician's appointment), informational support (e.g., knowledge, education or advice in problem-solving), and emotional support (e.g., empathy, reassurance, etc.). [83] Social support can reduce the rate of stress during pregnancy. Studies have found that those who had a large change in their life with a small amount of social support has a higher chance of complications. Whereas those with a larger support system would have a chance for less complications. [84]

Management

Stress management refers to a wide spectrum of techniques and psychotherapies aimed at controlling a person's levels of stress, especially chronic stress, usually for the purpose of improving everyday functioning. It involves controlling and reducing the tension that occurs in stressful situations by making emotional and physical changes.

Prevention and resilience building

Decreasing stressful behaviors is a part of prevention. Some of the common strategies and techniques are: self-monitoring, tailoring, material reinforcement, social reinforcement, social support, self-contracting, contracting with significant other, shaping, reminders, self-help groups, and professional help. [85] [ further explanation needed ]

Although many techniques have traditionally been developed to deal with the consequences of stress, considerable research has also been conducted on the prevention of stress, a subject closely related to psychological resilience-building. A number of self-help approaches to stress-prevention and resilience-building have been developed, drawing mainly on the theory and practice of cognitive-behavioral therapy. [86]

Biofeedback may also play a role in stress management. A randomized study by Sutarto et al. assessed the effect of resonant breathing biofeedback (recognize and control involuntary heart rate variability) among manufacturing operators; depression, anxiety and stress significantly decreased. [87] [ non-primary source needed ]

Exercising to reduce stress

Studies have shown that exercise reduces stress. [88] [25] Exercise effectively reduces fatigue, improves sleep, enhances overall cognitive function such as alertness and concentration, decreases overall levels of tension, and improves self-esteem. [88] Because many of these are depleted when an individual experiences chronic stress, exercise provides an ideal coping mechanism. Despite popular belief, it is not necessary for exercise to be routine or intense in order to reduce stress; as little as five minutes of aerobic exercise can begin to stimulate anti-anxiety effects. [88] Further, a 10-minute walk may have the same psychological benefits as a 45-minute workout, reinforcing the assertion that exercise in any amount or intensity will reduce stress. [88] Cycling and walking activities have lower stress scores when compared to other modes of transport or commuting. [25]

Theoretical explanations

A multitude of theories have been presented in attempts to explain why exercise effectively reduces stress. One theory, known as the time-out hypothesis, claims that exercise provides distraction from the stressor. The time out hypothesis claims that exercise effectively reduces stress because it gives individuals a break from their stressors. This was tested in a recent study of college women who had identified studying as their primary stressor. [89] The women were then placed under four conditions at varying times: "rest," "studying," "exercising," and "studying while exercising." The stress levels of the participants were measured through self-assessments of stress and anxiety symptoms after each condition. The results demonstrated that the "exercise" condition had the most significant reduction in stress and anxiety symptoms. [89] These results demonstrate the validity of the time-out hypothesis. [89] It is also important to note that exercise provided greater stress reduction than rest.

Coping mechanisms

The Lazarus and Folkman model suggests that external events create a form of pressure to achieve, engage in, or experience a stressful situation. Stress is not the external event itself, but rather an interpretation and response to the potential threat; this is when the coping process begins. [90]

There are various ways individuals deal with perceived threats that may be stressful. However, people have a tendency to respond to threats with a predominant coping style, in which they dismiss feelings, or manipulate the stressful situation. [90]

There are different classifications for coping, or defense mechanisms, however they all are variations on the same general idea: There are good/productive and negative/counterproductive ways to handle stress. Because stress is perceived, the following mechanisms do not necessarily deal with the actual situation that is causing an individual stress. However, they may be considered coping mechanisms if they allow the individual to cope better with the negative feelings/anxiety that they are experiencing due to the perceived stressful situation, as opposed to actually fixing the concrete obstacle causing the stress. The following mechanisms are adapted from the DSM-IV Adaptive Functioning Scale, APA, 1994.

Another way individuals can cope with stress is by the way one perceives stress. Perceptions of stress are critical for making decisions and living everyday life. The outlook or the way an individual perceives the given situation can affect the manner to which the individual handles stress, whether it be positive or negative. Too much stress can be detrimental to the individual and can cause negative psychological and physical health effects. [91]

Highly adaptive/active/problem-focused mechanisms

These skills are what one could call as “facing the problem head on”, or at least dealing with the negative emotions experienced by stress in a constructive manner. (generally adaptive)

  • Affiliation ("tend and befriend") – involves dealing with stress by turning to a social network for support, but an individual does not share with others in order to diffuse or avoid the responsibility. [92] [93]
  • Humour – the individual steps outside of a situation in order to gain greater perspective, and also to highlight any comic aspect to be found in their stressful circumstances. [92]
Coping through laughter Two people laughing.jpg
Coping through laughter
“The Association for Applied and Therapeutic Humour defines therapeutic humour as ‘any intervention that promotes health and wellness by stimulating a playful discovery, expression or appreciation of the absurdity of or incongruity of life’s situations. This intervention may enhance health or be used as a complementary treatment of illness to facilitate healing or coping whether physical, emotional, cognitive, or spiritual”. [94]
Sigmund Freud, suggested that humour was an excellent defensive strategy in emotional situations. [90] When one laughs during a tough situation they feel absent from their worries, and this allows them to think differently. [94] When one experiences a different mind set, they feel more in control of their response, and how they would go about dealing with the event that caused stress.
Lefcourt (2001) suggests that this perspective-taking humour is the most effective due to its ability to distance oneself from the situation of great stress. [95] Studies show that the use of laughter and humour creates a sense of relief of stress that can last up to 45 minutes post-laughter. [94]
Also, most hospitalized children have been seen to use laughter and play to relieve their fear, pain and stress. It has been discovered that there is a great importance in the use of laughter and humour in stress coping. [94] Humans should use humour as a means to transcend their original understanding of an external event, take a different perspective, in which their anxiety may be minimized by.
  • Sublimation – allows an "indirect resolution of conflict with neither adverse consequences nor consequences marked by loss of pleasure." [96] Essentially, this mechanism allows channeling of troubling emotions or impulses into an outlet that is socially acceptable.
  • Positive reappraisal – redirects thoughts (cognitive energy) to good things that are either occurring or have not occurred. This can lead to personal growth, self-reflection, and awareness of the power/benefits of one's efforts. [97] For example, studies on veterans of war or peacekeeping operations indicate that persons who construe a positive meaning from their combat or threat experiences tend to adjust better than those who do not. [98]

Other adaptive coping mechanisms include anticipation, altruism, and self-observation.

Mental inhibition/disavowal mechanisms

These mechanisms cause the individual to have a diminished (or in some cases non-existent) awareness about their anxiety, threatening ideas, fears, etc., that come from being conscious of the perceived threat.[ citation needed ]

  • Displacement – This is when an individual redirects their emotional feelings about one situation to another, less threatening one. [99]
  • Repression – Repression occurs when an individual attempts to remove all their thoughts, feelings, and anything related to the upsetting/stressful (perceived) threat out of their awareness in order to be disconnected from the entire situation. When done long enough in a successful way, this is more than just denial.
  • Reaction formation – An attempt to remove any “unacceptable thoughts” from one's consciousness by replacing them with the exact opposite. [100]

Other inhibition coping mechanisms include undoing, dissociation, denial, projection, and rationalization. Although some people claim that inhibition coping mechanisms may eventually increase the stress level because the problem is not solved, detaching from the stressor can sometimes help people to temporarily release the stress and become more prepared to deal with problems later on.

Active mechanisms

These methods deal with stress by an individual literally taking action, or withdrawing.

  • Acting out – Often viewed as counter-normative, or problematic behavior. Instead of reflecting or problem-solving, an individual takes maladaptive action. [93]
  • Passive aggression – When an individual indirectly deals with their anxiety and negative thoughts/feelings stemming from their stress by acting in a hostile or resentful manner towards others. Help-Rejecting Complaining can also be included in this category.

Health promotion

There is an alternative method to coping with stress, in which one works to minimize their anxiety and stress in a preventative manner.

Suggested strategies to improve stress management include: [101]

  1. Regular exercise – set up a fitness program, 3–4 times a week
  2. Support systems – to listen, offer advice, and support each other
  3. Time management – develop an organizational system
  4. Guided imagery and visualization – create a relaxing state of mind
  5. Progressive muscle relaxation – loosen tense muscle groups
  6. Assertiveness training – work on effective communication
  7. Journal writing – express true emotion, self-reflection
  8. Stress management in the workplace – organize a new system, switch tasks to reduce own stress.

Depending on the situation, all of these coping mechanisms may be adaptive, or maladaptive.

Prior to the introduction of the concept "stress" in the psychological sense c. 1955, [102] [103] people already identified a range of more nuanced ideas to describe and confront such emotions as worry, grief, concern, [104] obsession, fear, annoyance, anxiety, distress, suffering and passion. [105] By the 19th century, the popularisation of the nascent science of neurology made it possible to group some undifferentiated combination of one or more of these with an informal diagnosis such as "nerve strain". [106]

"Stress" has subsequently become a mainstay of pop psychology. [107] [108] Though stress is discussed throughout history from many distinct topics and cultures, there is no universal consensus over describing stress. [109] This has led to multiple kinds of research, looking at the different aspects of psychological stress and how it changes over a lifespan. [109]

Anxiety is an emotion which is characterised by an unpleasant state of inner turmoil and includes feelings of dread over anticipated events. Anxiety is different from fear in that fear is defined as the emotional response to a present threat, whereas anxiety is the anticipation of a future one. It is often accompanied by nervous behavior such as pacing back and forth, somatic complaints, and rumination.

<span class="mw-page-title-main">Stress (biology)</span> Organisms response to a stressor such as an environmental condition or a stimulus

Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. When stressed by stimuli that alter an organism's environment, multiple systems respond across the body. In humans and most mammals, the autonomic nervous system and hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress. Two well-known hormones that humans produce during stressful situations are adrenaline and cortisol.

Stress management consists of a wide spectrum of techniques and psychotherapies aimed at controlling a person's level of psychological stress, especially chronic stress, generally for the purpose of improving the function of everyday life. Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, sleep problems, and depression. The process of stress management is a key factor that can lead to a happy and successful life in modern society. Stress management provides numerous ways to manage anxiety and maintain overall well-being.

Coping refers to conscious or unconscious strategies used to reduce and manage unpleasant emotions. Coping strategies can be cognitions or behaviors and can be individual or social. To cope is to deal with struggles and difficulties in life. It is a way for people to maintain their mental and emotional well-being. Everybody has ways of handling difficult events that occur in life, and that is what it means to cope. Coping can be healthy and productive, or destructive and unhealthy. It is recommended that an individual cope in ways that will be beneficial and healthy. "Managing your stress well can help you feel better physically and psychologically and it can impact your ability to perform your best."

<span class="mw-page-title-main">Social support</span> Support systems for individuals

Social support is the perception and actuality that one is cared for, has assistance available from other people, and most popularly, that one is part of a supportive social network. These supportive resources can be emotional, informational, or companionship ; tangible or intangible. Social support can be measured as the perception that one has assistance available, the actual received assistance, or the degree to which a person is integrated in a social network. Support can come from many sources, such as family, friends, pets, neighbors, coworkers, organizations, etc.

A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.

<span class="mw-page-title-main">Emotional detachment</span> Inability and/or disinterest in emotionally connecting to others

In psychology, emotional detachment, also known as emotional blunting, is a condition or state in which a person lacks emotional connectivity to others, whether due to an unwanted circumstance or as a positive means to cope with anxiety. Such a coping strategy, also known as emotion-focused coping, is used when avoiding certain situations that might trigger anxiety. It refers to the evasion of emotional connections. Emotional detachment may be a temporary reaction to a stressful situation, or a chronic condition such as depersonalization-derealization disorder. It may also be caused by certain antidepressants. Emotional blunting, also known as reduced affect display, is one of the negative symptoms of schizophrenia.

Sex is correlated with the prevalence of certain mental disorders, including depression, anxiety and somatic complaints. For example, women are more likely to be diagnosed with major depression, while men are more likely to be diagnosed with substance abuse and antisocial personality disorder. There are no marked gender differences in the diagnosis rates of disorders like schizophrenia and bipolar disorder. Men are at risk to suffer from post-traumatic stress disorder (PTSD) due to past violent experiences such as accidents, wars and witnessing death, and women are diagnosed with PTSD at higher rates due to experiences with sexual assault, rape and child sexual abuse. Nonbinary or genderqueer identification describes people who do not identify as either male or female. People who identify as nonbinary or gender queer show increased risk for depression, anxiety and post-traumatic stress disorder. People who identify as transgender demonstrate increased risk for depression, anxiety, and post-traumatic stress disorder.

The term eustress means "beneficial stress"—either psychological, physical, or biochemical/radiological (hormesis).

<span class="mw-page-title-main">Allostatic load</span> Wear and tear on the body due to stress

Allostatic load is "the wear and tear on the body" which accumulates as an individual is exposed to repeated or chronic stress. The term was coined by Bruce McEwen and Eliot Stellar in 1993. It represents the physiological consequences of chronic exposure to fluctuating or heightened neural or neuroendocrine response which results from repeated or prolonged chronic stress.

Psycho-oncology is an interdisciplinary field at the intersection of physical, psychological, social, and behavioral aspects of the cancer experience for both patients and caregivers. Also known as psychiatric oncology or psychosocial oncology, researchers and practitioners in the field are concerned with aspects of individuals' experience with cancer beyond medical treatment, and across the cancer trajectory, including at diagnosis, during treatment, transitioning to and throughout survivorship, and approaching the end-of-life. Founded by Jimmie Holland in 1977 via the incorporation of a psychiatric service within the Memorial Sloan Kettering Cancer Center in New York, the field has expanded drastically since and is now universally recognized as an integral component of quality cancer care. Cancer centers in major academic medical centers across the country now uniformly incorporate a psycho-oncology service into their clinical care, and provide infrastructure to support research efforts to advance knowledge in the field.

Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. There is a wide range of chronic stressors, but most entail relatively prolonged problems, conflicts and threats that people encounter on a daily basis. Several chronic stressors have been identified as associated with disease and mortality including "neighbourhood environment, financial strain, interpersonal stress, work stress and caregiving."

Dispositional affect, similar to mood, is a personality trait or overall tendency to respond to situations in stable, predictable ways. This trait is expressed by the tendency to see things in a positive or negative way. People with high positive affectivity tend to perceive things through "pink lens" while people with high negative affectivity tend to perceive things through "black lens". The level of dispositional affect affects the sensations and behavior immediately and most of the time in unconscious ways, and its effect can be prolonged. Research shows that there is a correlation between dispositional affect and important aspects in psychology and social science, such as personality, culture, decision making, negotiation, psychological resilience, perception of career barriers, and coping with stressful life events. That is why this topic is important both in social psychology research and organizational psychology research.

Cognitive appraisal is the subjective interpretation made by an individual to stimuli in the environment. It is a component in a variety of theories relating to stress, mental health, coping, and emotion. It is most notably used in the transactional model of stress and coping, introduced in a 1984 publication by Richard Lazarus and Susan Folkman. In this theory, cognitive appraisal is defined as the way in which an individual responds to and interprets stressors in life. A variety of mental disorders have been observed as having abnormal patterns of cognitive appraisal in those affected by the disorder. Other work has detailed how personality can influence the way in which individuals cognitively appraise a situation.

Psychological hardiness, alternatively referred to as personality hardiness or cognitive hardiness in the literature, is a personality style first introduced by Suzanne C. Kobasa in 1979. Kobasa described a pattern of personality characteristics that distinguished managers and executives who remained healthy under life stress, as compared to those who developed health problems. In the following years, the concept of hardiness was further elaborated in a book and a series of research reports by Salvatore Maddi, Kobasa and their graduate students at the University of Chicago.

<span class="mw-page-title-main">Effects of stress on memory</span> Overview of the effects of stress on memory

The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. Stimuli, like stress, improved memory when it was related to learning the subject. During times of stress, the body reacts by secreting stress hormones into the bloodstream. Stress can cause acute and chronic changes in certain brain areas which can cause long-term damage. Over-secretion of stress hormones most frequently impairs long-term delayed recall memory, but can enhance short-term, immediate recall memory. This enhancement is particularly relative in emotional memory. In particular, the hippocampus, prefrontal cortex and the amygdala are affected. One class of stress hormone responsible for negatively affecting long-term, delayed recall memory is the glucocorticoids (GCs), the most notable of which is cortisol. Glucocorticoids facilitate and impair the actions of stress in the brain memory process. Cortisol is a known biomarker for stress. Under normal circumstances, the hippocampus regulates the production of cortisol through negative feedback because it has many receptors that are sensitive to these stress hormones. However, an excess of cortisol can impair the ability of the hippocampus to both encode and recall memories. These stress hormones are also hindering the hippocampus from receiving enough energy by diverting glucose levels to surrounding muscles.

Social stress is stress that stems from one's relationships with others and from the social environment in general. Based on the appraisal theory of emotion, stress arises when a person evaluates a situation as personally relevant and perceives that they do not have the resources to cope or handle the specific situation.

Emotional approach coping is a psychological construct that involves the use of emotional processing and emotional expression in response to a stressful situation. As opposed to emotional avoidance, in which emotions are experienced as a negative, undesired reaction to a stressful situation, emotional approach coping involves the conscious use of emotional expression and processing to better deal with a stressful situation. The construct was developed to explain an inconsistency in the stress and coping literature: emotion-focused coping was associated with largely maladaptive outcomes while emotional processing and expression was demonstrated to be beneficial.

There is empirical evidence of the causal impact of social relationships on health. The social support theory suggests that relationships might promote health especially by promoting adaptive behavior or regulating the stress response. Troubled relationships as well as loneliness and social exclusion may have negative consequences on health. Neurosciences of health investigate the neuronal circuits implicated in the context of both social connection and disconnection.

Tracey A. Revenson is a health psychologist known for her research on how people cope with chronic illness and how people's lifestyles can affect their health and influence their coping mechanisms. She holds the position of Professor of Psychology at Hunter College and the Graduate Center of the City University of New York, and directs the Coping and health in context (CHiC) lab.
