Chapter 4: Stress and Stress Management
In the early 1930s, a young medical researcher named Hans Selye was hunting for a new hormone. Working in a Montreal laboratory, he injected laboratory rats with extracts from animal organs and waited to see what would change in their bodies. Something strange happened. Whatever he injected — one extract or another, or even a harmless salt solution — the rats developed the same three changes: swollen adrenal glands, shrunken immune tissue, and small ulcers in the stomach.
At first Selye thought he had simply failed. His clumsy handling of the frightened animals — dropping them, chasing them around the room — seemed to spoil every experiment. Then a deeper idea struck him. Perhaps the rats were not reacting to the chemicals at all. Perhaps they were reacting to the ordeal itself: to being handled, startled and hurt.
The body, he realised, answers many different demands in one common way. He borrowed a word from engineering, where it names the load a beam or bridge must bear, and called this response “stress”. Selye had stumbled upon one of the most important ideas in modern psychology — that our minds and bodies meet pressure through a single, predictable pattern. It is a pattern you carry with you every time you sit for an examination, quarrel with a friend, or wait anxiously for a result.

This chapter will help you answer the questions below.
4.1 Meaning of Stress — its Basic Nature
You use the word “stress” constantly — before a test, after an argument, during a long power cut on a hot afternoon. In everyday speech it stretches to cover almost anything unpleasant. In psychology, though, the word has a precise meaning that is worth pinning down before we go any further.
The word travels a long way. It comes from the Latin stringere, meaning “to draw tight”, and passed into English through an old French word for narrowness and hardship. Engineers borrowed it too, using “stress” for the force or load that presses on a beam or a bridge. In the 1930s, Hans Selye carried the term into biology and psychology, and it is his scientific meaning that we use today.
So what is stress? At its simplest, stress is the response of our mind and body to any demand or threat that disturbs our normal balance. A stressor is the demand or event that sets off this response. Notice that the word points in two directions at once — towards the pressure placed on us, and towards our reaction to that pressure.
Selye described stress in bodily terms. He saw it as the body’s general, automatic reply to being pushed out of balance, whatever the source of that push.
Modern psychology adds a second idea: stress is not simply in the event, nor simply in the person, but in the relationship between the two. It appears when we judge that a demand is about to outrun our ability to cope with it.
This second definition explains a great deal. A demand that overwhelms one person may barely trouble another, because the two differ in what they can bring to it. Stress, in short, is a matter of imbalance — between what a situation asks of us and what we believe we can give.
Every stress reaction disturbs our homeostasis, the body’s built-in tendency to hold its internal state steady and balanced. When a stressor throws that balance off, the mind and body work hard, and sometimes at a cost, to restore it.
From all of this, a few basic features of stress stand out. It is a reaction of body and mind to a stimulus; it appears when we cannot comfortably cope with a change or demand; it flares when our well-being feels threatened in some way; and it grows out of a gap between what is demanded of us and what we can actually manage.
4.1.1 Eustress, Distress and Strain
If stress simply wore us down, life would be easier to understand — but it does not. Selye noticed something more interesting: up to a point, stress can sharpen us and lift our performance. A degree of pressure is not the enemy of good work; it is often the engine of it.
This useful, energising stress has a name: eustress (the prefix eu- means “good”). Eustress is the pleasant tension of a demand you feel ready to meet. The excitement before a big match, the buzz of preparing for a wedding, the alertness of stepping into a new job after a promotion — all of these are eustress. The demand is real, but you experience it as a challenge rather than a burden.
When the pressure grows too heavy, or drags on too long, the picture changes. Now stress lowers your productivity, drains your creativity and harms your health. This damaging form is called distress — the “bad” stress that most people simply call “stress”. An older word for it, borrowed from the same engineering image, is strain.
The line between the two is not fixed. The very same event can be eustress for one person and distress for another, and even eustress can tip into distress if it lasts beyond what you can sustain. What matters is the balance between the demand and your sense of being able to meet it.
4.1.2 Types of Stress
Stress can be sorted, by the kind of demand that produces it, into three broad types. The three overlap in real life, but separating them helps us see where a particular strain is coming from.
Physical stress arises from demands placed directly on the body. Illness, injury, going without sleep, hunger, extreme heat or cold, and hard physical exertion all push the body out of balance and set off the stress response.
Psychological stress arises from within — from our thoughts, feelings, worries and expectations rather than from any bodily injury. Fear before an examination, the ache of a broken friendship, guilt over a mistake, or endless anxious “what ifs” are all psychological in origin. Much of the stress that troubles students belongs here.
Environmental stress arises from the world around us. Constant noise, air and water pollution, crowding, poor or glaring lighting, and cramped or unpleasant surroundings quietly wear away at our resources, even when we barely notice them.
4.1.3 Stress as a Process
Stress is not a single, frozen moment. It is better understood as a process — an unfolding sequence in which a demand meets a person, is weighed up, and produces effects that can then feed back and create fresh demands.
A stressor may be negative, like a bereavement, an illness or a failure. But it can also be positive, like a marriage, a new job or the birth of a child. This surprises people, yet even happy events demand adjustment, and adjustment is itself a source of stress. What generates stress is change and demand, not unpleasantness alone.
The process runs roughly as follows. First, a demand — physical or psychological — is placed on the person. Next, the person sizes up the demand and, at the same time, estimates their own ability to meet it. If the two seem to match, the demand is handled easily and little stress appears.
But if the person perceives an imbalance — the demand looks larger than what they can manage — stress begins to build. The body and mind respond together: anxiety rises, worries multiply, the heart beats faster, muscles tighten, and concentration may waver. As shown in Fig. 4.1-1, this response then shapes what happens next.
Diagram
Fig. 4.1-1 – flow: demand placed on person → person weighs demand against own capabilities → capabilities match demand = little stress → OR imbalance perceived (demand > capability) = stress response (worry, arousal, tension) → performance improves or declines → outcome may create a new demand (loops back to start)
If performance improves, the person meets the demand, the stressor fades, and the stress eases. If performance falls short, new difficulties appear — a fresh demand is created, and the whole cycle turns again. This is why stress so often feels like a chain rather than a single blow.
Both too much demand and too little can start this cycle. Overload — more work, responsibility or pressure than a person can absorb — is an obvious source of stress. But underload — too little to do, with the boredom and sense of being neglected that comes with it — is stressful as well. Balance, once again, is the key.
4.1.4 The General Adaptation Syndrome: Selye’s Model
Hans Selye wanted to describe what the body actually does when a stressor keeps pressing on it. From long research he concluded that, whatever the stressor, the body defends itself through the same broad sequence of physical stages. He named this pattern the General Adaptation Syndrome (GAS).
The name itself explains the idea. It is general, because the response involves the whole body rather than one organ; it is adaptation, because the body is trying to cope with and adjust to the threat; and it is a syndrome, because a recognisable cluster of changes appears together. The pattern unfolds in three stages, always in the same order.
The first is the alarm reaction. Here the body is suddenly confronted with a threat and mobilises for emergency. The sympathetic branch of the nervous system fires, flooding the body with adrenaline — a hormone that rapidly rouses the body for action. Heart rate, blood pressure, breathing and blood sugar all shoot up, readying the person to fight or to flee.
The second is the resistance stage. The first shock has passed, and the body settles into a sustained, high-level effort to fight the stressor and return to normal. Outward alarm symptoms often fade, so the person may look calm again. But the body is quietly spending its reserves, helped by a longer-acting stress hormone called cortisol. During this stage the person copes with the original stressor but becomes poorly equipped to handle any new stressor arriving on top of it.
The third is the exhaustion stage. If the stressor grips for too long, the reserves that powered resistance run dry. The body’s power to resist collapses, defences fail, and the person becomes open to illness, breakdown and — in work settings — burnout. In severe, prolonged cases the effects can be grave. Figure 4.1-2 traces how the body’s resistance rises and then falls across the three stages.
Diagram

That limitation is important, and it opens the door to a very different kind of model — one that begins not with the body, but with the way we think.
4.1.5 The Cognitive Appraisal Model: Lazarus and Folkman
If GAS asks how the body responds, the model proposed by Richard Lazarus and Susan Folkman in 1984 asks why the same event stresses one person and not another. Their answer is that stress depends less on the event itself than on how we interpret it. This mental interpretation is called cognitive appraisal.
The idea is that a situation only becomes a stressor once we have judged it to be one. Two stages of judgement are involved, and the model is usually pictured as flowing from one to the next, as in Fig. 4.1-3.
Diagram
Fig. 4.1-3 – flow: stressful event → primary appraisal (is this irrelevant / positive / or harmful, threatening, or challenging?) → if judged stressful → secondary appraisal (are my coping resources adequate?) → resources adequate = little or no stress → resources inadequate = stress
In primary appraisal, the person makes a first judgement about what the situation means for them. It may lead to one of three verdicts: the situation is not important to me; it is good or harmless; or it is stressful. Only the last verdict produces stress. A stressful appraisal itself comes in three shades — harm or loss (damage already done), threat (harm expected in the future), and challenge (a demanding situation seen as a chance to grow, which produces the positive stress of eustress).
In secondary appraisal, the person judges their ability to cope: “What can I do about this? Do I have the resources, skills and support to handle it?” If the answer feels adequate, stress stays low. If coping seems inadequate, stress rises.
Although we call them primary and secondary, the two appraisals are not neatly first-and-second in time. They often happen together, and our sense of how well we can cope can shape whether we saw the event as threatening in the first place.
4.2 Common Causes of Stress
We have seen that stress grows out of an imbalance between what a situation demands and what a person feels able to give. That raises an obvious next question: where do these demands actually come from? Until we can name the causes of our stress, we cannot hope to manage it.
The causes of stress fall into two broad families. Some are external or situational — they come from events and conditions in the world around us. Others are internal or dispositional — they come from within a person’s own make-up, from their needs, personality and habits of thought. We will take each family in turn.
4.2.1 External or Situational Causes
External causes are the stressors that life places in front of us — the events, demands and surroundings we did not choose and often cannot control. Four kinds matter most.
4.2.1.1 Stressful Life Events
A stressful life event is a major change that arrives, often suddenly, and demands a large readjustment in how we live. The death of a loved one, a divorce, the loss of a job, a serious illness, academic failure, imprisonment or moving to a new city all fall into this group.
Such events shake people deeply. If a person cannot find a way to cope within a manageable stretch of time, their normal functioning — at work, at home, in relationships — can be badly disturbed. Sudden, heavy life events have been linked to both physical and psychiatric problems.
Crucially, the event need not be unhappy to be stressful. A wedding, a promotion or the birth of a child demands adjustment too, and so it carries its own stress. What taxes us is the sheer amount of change, whether the change is welcome or unwelcome.
As Figure 4.2-1 shows, the events demanding the greatest readjustment tend to involve the loss of, or a major change in, our closest relationships.
Diagram

4.2.1.2 Minor Hassles of Everyday Life
Not all stress comes from dramatic events. Much of it comes from daily hassles — the small, repeated irritations of ordinary life. A traffic jam, a power cut, a crowded bus, a quarrel over something trivial, a misplaced set of keys, money worries or health worries: each is minor in itself.
Their power lies in their frequency. What is small in intensity becomes large through sheer repetition, quietly chipping away at our resources day after day. Over time, this steady drip can wear down our ability to adapt and can feed into real physical and psychological problems.
Some researchers argue that these everyday hassles predict ill-health as strongly as the big life events do — precisely because they never seem to stop. A single crisis passes; the daily grind returns every morning.
4.2.1.4 The Physical Environment
There is a deeper irony in the way humans and their surroundings interact. As people reshape the natural world for their own needs — through deforestation, industrial waste, loud machinery and endless construction — they foul the very environment that then acts back upon their minds and bodies.
The result is pollution of the air, water, soil and soundscape, alongside crowding and a growing scarcity of shared resources. These degraded surroundings become stressors in their own right: persistent noise, overcrowding, foul air, and natural disasters such as floods all place a real burden on human well-being. In pursuing a more comfortable life, we often manufacture the stressors that harm us.
4.2.2 Internal or Dispositional Causes
Stress does not come only from the outside. Much of it is generated within — from our own needs, our personality and our characteristic ways of thinking and feeling. This is why the same event stresses one person severely and barely touches another: they bring different dispositions to it. Personality and attitude, in other words, are themselves causes of stress.
4.2.2.1 Personality Types: Type A and Type B
Studying patients with heart trouble, the cardiologists Meyer Friedman and Ray Rosenman noticed that a certain kind of person seemed especially prone to stress. They described two contrasting personality patterns.
The Type A personality is competitive, ambitious and driven. Such people are impatient and hurried, carry a constant sense of time pressure, set very high targets, and are easily irritated or made hostile when things get in their way. Their restless intensity keeps their stress levels high.
The Type B personality is, in many ways, the opposite. Type B people are relaxed, easy-going and patient. They are less competitive, take demands in their stride, manage stressful situations calmly, and seldom feel seriously distressed.
These are broad tendencies, not rigid boxes. Most people are a blend of the two, leaning one way in some situations and the other way elsewhere.
How Men and Women Cope Differently
Research suggests some average differences in how men and women tend to handle stress. Under pressure, women are, on the whole, somewhat more likely to seek out and offer social support — a pattern sometimes called “tend-and-befriend”. Men are, on average, a little more likely to withdraw, to keep feelings bottled up, and some drift towards unhealthy habits as a result.
These are only tendencies, with very wide variation between individuals. Plenty of men lean on friends and family, and plenty of women prefer to cope alone. The lesson is not about gender but about method: reaching out for support, whoever you are, is one of the more effective ways to manage stress.
4.2.2.2 Locus of Control
People differ in how much control they believe they have over what happens to them. This general belief is called the locus of control, an idea developed by the psychologist Julian Rotter.
A person with an internal locus of control believes that outcomes flow mainly from their own effort, choices and actions. A person with an external locus of control believes that outcomes are decided largely by luck, fate or other powerful people.
This belief shapes how we meet stress. On the whole, people with an internal locus of control cope better: because they feel able to influence events, they take active, problem-solving steps rather than sitting back, and they are less likely to feel helpless. People with an external locus of control are more prone to a sense of helplessness when demands pile up, since they see the outcome as beyond their reach.
There is a subtle exception. When a situation is genuinely uncontrollable, a person with a very strong internal locus may over-blame themselves for what they could not have changed. But taken across life as a whole, a reasonable sense of personal control protects against stress rather than adding to it.
4.2.2.3 Optimism and Pessimism
Attitude, too, decides how heavily stress lands on us. Optimism is a general expectation that things will turn out well and that difficulties can be overcome. Pessimism is the opposite habit — expecting the worst and dwelling on what might go wrong.
Optimists tend to experience less stress. They hold a hopeful yet fairly realistic picture of events, keep a sense of purpose, and stay open to other people’s viewpoints and to new ideas. They take honest credit for their successes and accept blame for failures without being crushed by them.
Pessimists, by contrast, magnify threats and setbacks, and so they feel more threatened by the same events. In this way a person’s outlook, quite apart from their circumstances, can either shield them from stress or expose them to more of it.
4.2.2.4 Frustration, Conflict and Pressure
Three inner experiences deserve special mention, because each is a familiar and powerful source of stress.
Frustration is the unpleasant feeling that arises when our progress towards a goal is blocked — by an obstacle, a delay, a loss, or by our own limits. It is sharpened when we set our aspirations unrealistically high, because a goal placed beyond reach guarantees a steady supply of frustration.
Conflict is the stress of being pulled between two or more incompatible goals or motives, so that choosing one means giving up another. Psychologists describe a few common patterns: an approach–approach conflict pulls us between two attractive options and is usually mild; an avoidance–avoidance conflict traps us between two unpleasant options and is harder to bear; and an approach–avoidance conflict, the most common of all, ties us to a single goal that has both attractive and unattractive sides at once.
Pressure is the demand to meet certain standards or expectations. It may be imposed from outside — deadlines, competition, the hopes of one’s family — or set by oneself. Pressure pushes us to act or perform, and it grows heavier as the standards climb higher and the time runs shorter.
4.3 Effects of Stress on Health and Performance
Stress does not stay in the mind. Left unmanaged, and stretched over long periods, it works its way into the body, into our health, and into how well we do the things we set out to do. This section follows those effects — first into the machinery of the body, then into the quality of our performance.
4.3.1 How Stress Upsets the Internal Mechanism and Balance
The link between stress and ill-health is strong. Doctors estimate that stress is one of the major contributors to a large share of life-threatening conditions, including ulcers, heart disease and diabetes. To see how, we must follow what actually happens inside the body.
Stress disturbs our homeostasis, and to fight back the body springs into action through the autonomic nervous system (ANS) — the part of the nervous system that quietly runs our automatic functions, such as heartbeat and digestion. The ANS has two branches that work against each other.
The sympathetic nervous system (SNS) is the emergency branch. It fires up during stress, readying the body to fight or flee: it raises heart rate, blood pressure and muscle tension, and it triggers the adrenal glands to pour out adrenaline and a related hormone, noradrenaline. These hormones speed the heart, sharpen alertness and flood the muscles and brain with glucose.
The parasympathetic nervous system (PNS) is the calming branch. It works to restore balance — slowing the heart, lowering blood pressure and conserving the body’s energy. In moments of stress, the sympathetic branch outruns the calming branch, which is exactly why a period of stress keeps going instead of settling.
Alongside this fast nervous response runs a slower, hormonal one, through what is called the adrenocorticotropic axis, shown in Figure 4.3-1. When the brain registers a stressor, it signals the hypothalamus, which releases a chemical messenger (corticotropin-releasing factor). This travels to the pituitary gland, prompting it to release adrenocorticotropic hormone (ACTH). ACTH in turn drives the adrenal glands to pump out cortisol.
Diagram
Fig. 4.3-1 – labelled pathway of the adrenocorticotropic (HPA) axis with downward arrows: perception of stressor → hypothalamus (releases corticotropin-releasing factor) → pituitary gland (releases ACTH) → adrenal glands → cortisol and other stress hormones into the bloodstream
Cortisol breaks down fats and proteins to supply the body with glucose, the fuel it needs to meet the stressor. For a short spell this is helpful. But if stress drags on, the constant breakdown of proteins turns harmful — because proteins are also needed to build the white blood cells that fight infection. Here, in a single mechanism, lies the deep link between a stressed mind and a vulnerable body.
4.3.1.1 Effect on the Immune System
The immune system is the body’s defence force — the mechanism by which it recognises and destroys harmful invaders such as bacteria, viruses and even its own cells that have turned cancerous. When foreign invaders (antigens) enter, white blood cells called lymphocytes multiply; some, the T-cells, attack the invaders directly, while others, the B-cells, produce antibodies that neutralise them.
Prolonged stress weakens this defence. As we have just seen, sustained high cortisol eats into the proteins needed to build white blood cells, so the body’s guard is lowered and illness slips through more easily. Uncontrollable, unrelieved stress seems to hit the immune system hardest of all.
4.3.1.2 Hypertension
Hypertension means persistently high blood pressure. It is often called a “silent killer” because it usually gives no clear warning sign, yet it slowly damages vital organs — the heart, kidneys, brain and eyes.
Stress feeds hypertension directly. The surge of stress hormones constricts the blood vessels, driving blood pressure up. Stressed people also tend to fall into unhealthy habits, such as drinking or poor sleep, which push it higher still. Sustained hypertension can lead on to heart problems, stroke and other serious harm.
4.3.1.3 Cardiac Problems
Extensive research links high, chronic stress — and the Type A personality in particular — to heart trouble. Type A individuals are competitive and target-driven; they judge themselves by their achievements, and their levels of excitement, anger and tension tend to run high.
All of this creates a great deal of internal pressure, and the resulting stress strains the heart much as it drives up blood pressure. Momentary stress sharply raises heart rate and the force of the heartbeat, and repeated episodes can inflame the arteries that feed the heart, raising the risk of a heart attack over time.
4.3.1.4 Psychosomatic Disorders: Ulcers, Asthma and Diabetes
Some illnesses sit right at the meeting point of mind and body. These are the psychosomatic disorders — physical illnesses in which psychological factors such as stress play a real part in causing or worsening them. The word joins psyche (mind) and soma (body), a reminder of how tightly the two are woven together.
Ulcers are open sores in the protective lining of the stomach, the duodenum or the food-pipe. Stress, combined with poor habits such as fatty foods, alcohol, caffeine and smoking, can increase acid secretion in the stomach; over time this acid wears away the protective lining and worsens the ulcer.
Asthma is a long-term lung condition in which the airways inflame and narrow, making breathing hard. Stressful life events and environmental stressors are recognised risk factors, and stress can sharpen an attack — which in turn makes the person more anxious, trapping them in a cycle of stress, breathlessness and fear.
Diabetes involves a persistently raised level of sugar in the blood. Because cortisol both raises blood sugar and blunts the action of insulin (the hormone that controls it), long-term stress can keep blood sugar high and so contribute to the condition.
Each of these is a genuine medical illness that must be diagnosed and treated by a qualified doctor; noticing stress in your own life is not the same as identifying a disease, and no textbook description can take the place of professional care.
4.3.2 Stress and Performance: The Inverted-U Curve
There is a popular belief that stress lifts performance — that a little pressure makes us sharper. Like many popular beliefs, it is half right. The truth is captured by a simple curve.
To understand it, we need the idea of arousal — the body’s general state of physiological activation and alertness. Stress raises arousal. The relationship between arousal and performance is not a straight line but an inverted-U — an upside-down U — as Figure 4.3-2 shows.
Diagram
Fig. 4.3-2 – inverted-U curve: performance (y-axis) against arousal or stress level (x-axis); performance rises from low arousal to a peak (marked “optimal level / comfort zone”) then falls away; the falling side labelled with fatigue point, then exhaustion, then burnout
At very low arousal — when a task is dull or a person is under-stimulated — performance is poor, because there is little motivation or energy. As arousal rises, performance climbs, reaching its peak at an optimal, middle level of stress. This peak is sometimes called the “comfort zone”: the exact level of stress at which we manage best.
Push arousal beyond that peak, however, and performance starts to fall. Stress now distracts rather than sharpens; the person reaches a point of fatigue, and the harder or more prolonged the stress, the steeper the decline. At the far end lie exhaustion and, ultimately, burnout.
The best level of arousal also depends on the task. For simple tasks, quite high arousal can still help; for difficult, complex tasks, the optimal level is lower, because too much arousal scrambles careful thinking.
4.3.3 Burnout
If stress at work becomes intense and never lets up, it can end in burnout — a state of deep physical, emotional and mental exhaustion produced by long-term, unrelieved stress. Burnout is where the falling side of the inverted-U curve finally bottoms out.
A person heading into burnout feels drained, irritable and ineffective. Motivation and enthusiasm dry up, and a weary cynicism sets in. It is typically the result of chronic pressure at work — heavy workloads, relentless deadlines and harsh appraisals — faced by someone who can no longer cope.
Burnout tends to build in stages rather than strike all at once. It often begins with a “honeymoon” of high enthusiasm for a new job; slides into a “fuel shortage” of fatigue and creeping dissatisfaction; hardens into “chronic symptoms” of exhaustion, illness and low mood; deepens into a “crisis” of pessimism, self-doubt and pronounced physical complaints; and ends by “hitting the wall”, where the person is so exhausted that they can no longer function on the job.
It is worth ending this section on a note of balance. Stress does not wear everyone down in the same way. Some people manage it so well that they perform superbly under heavy pressure. How stress affects performance depends on the individual’s own traits and on how demanding the task is — which is why we should be careful about making sweeping generalisations. The good news is that, with effective stress management, even a slide towards burnout can be halted and reversed — and how to do that is the subject of the next section.
4.4 Stress Management: Ineffective and Effective Strategies
Stressors are common to everyone, and there is no way to escape them entirely. What we can do is learn to manage stress — especially chronic stress — so that we keep functioning at our best. In today’s demanding world, our psychological, social and physical well-being depends heavily on how well we cope.
The word “cope” is worth pausing on. Coping is a person’s active, situation-specific effort to handle the demands that stress creates. It covers all the responses aimed at solving the problem and easing the strain.
We reach for coping methods almost by instinct. But not all of them work. Some really do help us master a situation; others give brief relief while leaving the real trouble untouched, or even making it worse. We will look first at the strategies that fail, and then at those that succeed.
4.4.1 Ineffective Strategies
Ineffective strategies are the unhealthy ways of coping that offer only temporary relief. The stressor lingers behind the relief, ready to return.
4.4.1.1 Defence Mechanisms
According to psychoanalytic theory, we sometimes protect ourselves from anxiety through unconscious mental tricks called defence mechanisms. They shield the ego from guilt or from thoughts and feelings that are painful or socially unacceptable. Because they work unconsciously, we rarely notice ourselves using them.
Defence mechanisms are not evil in themselves — they take the edge off distress. But leaned on too heavily in adult life, they become a mark of emotional immaturity, because they dodge the real problem instead of solving it. Here are the main ones.
Rationalization is justifying our unacceptable behaviour or feelings with logical-sounding but false reasons. A dieter who eats an extra slice of cake “so it won’t be wasted”, rather than admitting the craving, is rationalising.
Projection is attributing our own unacceptable thoughts or feelings to someone else. A person who strongly dislikes a colleague may insist, instead, that the colleague dislikes them.
Reaction formation is replacing an uncomfortable feeling with its exact opposite in our behaviour. Someone who resents a responsibility may hide it behind exaggerated, overprotective concern.
Regression is slipping back to less mature behaviour from an earlier stage of life when stress strikes. A child who had stopped thumb-sucking may start again after a new sibling is born.
Repression is pushing distressing thoughts or impulses out of conscious awareness, down into the unconscious, so that we are no longer aware of them at all.
Displacement is redirecting an emotion — often anger — from its real but threatening target onto a safer one. A man angry with his boss may come home and snap at his family.
Sublimation is channelling unacceptable impulses into socially approved, constructive activity, such as sport, art or work. It is generally regarded as the most mature and healthy of the defences.
4.4.1.2 Other Ineffective Strategies
Beyond the defence mechanisms, people fall into other unhelpful ways of coping. Some turn to substance use — alcohol, tobacco or other substances — as an escape; this only masks the stress while harming health and usually deepening the underlying trouble. Others adopt an unhealthy lifestyle, working long hours and sacrificing meals and sleep to finish tasks, which adds strain instead of relieving it.
Two further patterns are equally self-defeating. In behavioural avoidance, a person withdraws from or denies a stressful situation; because the stressor is never faced, it simply returns. And in a purely emotional response, a person becomes flooded with feeling — crying or lashing out — without ever turning to tackle the problem itself. In each case the emotion is discharged, but the stressor stays firmly in place.
4.4.2 Effective Strategies
Effective strategies work in the opposite direction. Instead of hiding the stressor, they either calm the body’s stress response or tackle the demand head-on — and they help in the long term as well as the short.
4.4.2.1 Relaxation Techniques
Stressors switch on the nervous system and disturb our homeostasis. Relaxation techniques work by switching on the body’s natural relaxation response — the calming, parasympathetic side of the nervous system — to restore balance and a state of calm. Several are widely used.
Deep breathing meditation is the simplest: slow, full, cleansing breaths that can be taken almost anywhere. Progressive muscle relaxation takes a two-step approach — systematically tensing and then releasing each muscle group in turn, which relaxes body and mind together. In body-scan meditation, a person moves their attention gently through the body, noticing each sensation in turn.
Meditation and mindfulness train the mind to settle: mindfulness is the practice of focusing on, and accepting, the experience of the present moment, which is thought to improve mental well-being. Creative visualisation, usually guided by a trained person, involves picturing a calm and pleasant scene to ease tension. A gentle massage, by loosening tight muscles, can serve the same relaxing purpose.
One technique deserves a special mention. Biofeedback teaches a person to control physiological responses that usually run on their own, such as heart rate. Using instruments that “feed back” information about the body, the person learns in stages — first becoming aware of a particular response, then learning to control it, and finally using that control during times of stress.
4.4.2.2 Yoga
Yoga is an ancient Indian practice that combines physical postures, controlled breathing and steady mental focus. Practised under proper guidance, it not only lowers stress and anxiety but also improves flexibility, strength, balance and stamina. Traditionally it is described as a series of steps, or limbs, that guide a person towards a calm and disciplined life. Five of these are the following.
Yama — ethical restraint: behaving in keeping with ethical standards in one’s dealings with others. Niyama — self-discipline: the personal observances and self-control one practises within oneself. Asana — posture: assuming various physical postures that improve the functioning of the body and help maintain balance.
Pranayama — breath control: breathing exercises that regulate the breath, refreshing the mind and body. Pratyahara — withdrawal of the senses: turning our awareness away from external objects and inward, so that we can observe our own habits and inner life.
4.4.3 Promoting Positive Health and Well-Being
The best defence against stress is not a single technique but a whole way of living that keeps a person strong and steady. Several habits work together to promote positive health and well-being.
Regular exercise is now firmly established as a stress-reducer: it not only keeps the body fit but also controls the hormones and chemicals that shape our mood, easing anxiety and low spirits. A balanced diet fuels both body and mind, supports the organs and strengthens immunity. Together with rest and a positive outlook, these form the basis of self-care — the everyday practice of looking after oneself.
Certain skills matter too. Life skills — such as problem-solving, decision-making, time-management and clear communication — help a person meet daily demands with confidence. Assertiveness is the ability to express one’s thoughts, feelings and needs clearly and calmly, including the ability to say no; it heads off a great deal of stress that comes from being pushed around. Rational thinking means challenging our own distorted, negative and irrational thoughts and replacing them with realistic ones, so that we do not manufacture stress in our own heads.
Relationships and support are powerful buffers. Improving relationships — through open communication, real listening and an acceptance of other people’s views — strengthens the ties we lean on. Social support itself comes in three forms: tangible support (practical or material help), informational support (useful advice or guidance) and emotional support (encouragement that boosts our confidence). And overcoming unhelpful habits — replacing avoidance and procrastination, which only postpone stress, with active problem-solving — removes stressors at their root rather than letting them return.
Finally, personality and outlook can be cultivated. Some people have a stress-resistant, or hardy, personality that helps them shrug off pressure that would flatten others.
Building on that, a stress-resistant approach also means keeping a sensible balance between one’s abilities, aspirations and achievements; growing one’s patience and tolerance for stress; reducing anxiety-inducing situations through good time-management; and holding on to positive thinking and a positive attitude — treating setbacks as normal, and even keeping a sense of humour, so that every failure becomes a step towards learning rather than a source of despair.
4.5 Summary
Stress is the response of mind and body to any demand or threat that disturbs our balance, and the demand or event that triggers it is a stressor. It arises from an imbalance between what a situation demands and what we feel able to give.
Selye described stress as the body’s non-specific response to any demand, while the modern view adds that a demand becomes stressful only when it is perceived to exceed our resources for coping.
Stress is not always harmful. Moderate, welcome stress is eustress, which sharpens performance; heavy or prolonged stress is distress (or strain), which lowers it. The very same event can be either, depending on the person.
By its source, stress takes three forms — physical (demands on the body), psychological (thoughts, worries and emotions) and environmental (the surroundings we live in).
Stress works as a process: a demand is placed, the person weighs it against their abilities, and if an imbalance is perceived the stress response follows, changing performance and often creating fresh demands. Both overload and underload are stressful, and even positive events count as stressors because they demand adjustment.
Selye’s General Adaptation Syndrome describes the body’s three-stage reply to a prolonged stressor, always in the same order — the alarm reaction (immediate fight-or-flight mobilisation), the resistance stage (sustained adaptation that quietly drains the body’s reserves) and the exhaustion stage (collapse of resistance once those reserves run out). Its weakness is that it is almost purely physical and ignores how a person interprets the stressor.
The Cognitive Appraisal Model of Lazarus and Folkman fills that gap: stress depends on appraisal. In primary appraisal we judge whether a situation is harmful, threatening or challenging; in secondary appraisal we judge whether we can cope. This is why the same event stresses one person and barely touches another.
The causes of stress divide into external or situational causes and internal or dispositional causes.
External causes include major stressful life events (studied by Holmes and Rahe, and taxing even when happy, because change itself demands adjustment), the daily hassles whose power lies in their frequency, work-related stress (workload or underload, role ambiguity, a poor environment, strained relations, career worries and performance appraisal), and the physical environment (pollution, noise, crowding and disasters).
Internal causes include personality type — the driven, impatient Type A feels more stress and greater cardiac risk than the relaxed Type B; locus of control — an internal sense of control generally buffers stress, while an external one invites helplessness; optimism versus pessimism; and the inner experiences of frustration (a blocked goal), conflict (a pull between goals) and pressure (a demand to meet standards).
Stress reaches the body through the nervous and hormonal systems. It activates the autonomic nervous system, whose sympathetic branch arouses the body (releasing adrenaline) while the parasympathetic branch calms it, and it drives the stress-hormone axis — hypothalamus to pituitary (ACTH) to adrenal glands — to release cortisol.
Cortisol supplies quick energy in the short term, but sustained cortisol breaks down the proteins the body needs to build immune cells — the central link between prolonged stress and physical illness.
Long-term stress weakens the immune system (shown in Kiecolt-Glaser and Glaser’s studies), raises blood pressure (hypertension), strains the heart (especially in Type A individuals) and contributes to psychosomatic disorders such as ulcers, asthma and worsened diabetes.
The link between stress and performance follows an inverted-U, the Yerkes-Dodson law: performance is best at a moderate level of arousal and falls when arousal is either too low or too high, with the best level being lower for difficult tasks.
Prolonged, unrelieved work stress can end in burnout — deep exhaustion, cynicism and ineffectiveness — which usually builds through stages, from an early “honeymoon” to finally “hitting the wall”. Because stress does not affect everyone equally, its effects should not be over-generalised.
Managing stress means coping: a person’s active, situation-specific effort to handle its demands. Coping strategies may be ineffective or effective.
Ineffective strategies bring only temporary relief while leaving the stressor untouched. They include the unconscious defence mechanisms — rationalization, projection, reaction formation, regression, repression, displacement and sublimation — along with substance use, an unhealthy lifestyle, avoidance and mere emotional venting.
Effective strategies either calm the stress response or tackle the demand directly. They include relaxation techniques (deep breathing, progressive muscle relaxation, body-scan meditation, mindfulness, visualisation, massage and biofeedback) and yoga, whose steps of yama, niyama, asana, pranayama and pratyahara train body and mind together.
Lasting protection comes from a healthy way of living: exercise, a balanced diet and self-care; life skills, assertiveness and rational thinking; strong relationships and social support (tangible, informational and emotional); replacing unhelpful habits; and cultivating a hardy, stress-resistant personality (Kobasa’s commitment, control and challenge) with a positive outlook. Seeking help when stress overwhelms is a strength, not a weakness.

4.7 Points to Ponder
If the very same event can be eustress for one person and distress for another, is it ever fair to call a situation “stressful” in itself — or only stressful for someone?
Selye held that the body answers every stressor in the same general way, while Lazarus held that the response depends entirely on how we appraise the situation. Can both claims be true at once, or must one be closer to the truth?
We saw that an internal sense of control usually protects us from stress. Can you imagine a situation in which believing you are in control might do more harm than good?
If a moderate amount of pressure actually improves performance, why do so many people try to remove stress from their lives entirely — and could a completely stress-free life carry costs of its own?
Defence mechanisms are called “ineffective” because they sidestep the real problem, yet almost everyone uses them. Is a coping strategy that brings genuine short-term relief always a poor one?
Modern life keeps inventing new comforts and conveniences, and yet stress seems only to grow. If our comforts rise but our stress does not fall, what might that tell us about where stress truly comes from?
