BEHAVIOR
MEETING LIFE CHALLENGES : STRESS
Stress: – The pattern of responses an organism makes to stimulus event that disturbs the equilibrium and exceeds a person’s ability to cope.
NATURE OF STRESS
Stress is not a factor that resides in the individual or the environment, instead it is embedded in an ongoing process that involves individuals transacting with their social and cultural environments, making appraisals of those encounters and attempting to cope with the issues that arise. Stress is a dynamic mental/cognitive state. It is a disruption in homeostasis or an imbalance that gives rise to a requirement for resolution of that imbalance or restoration of homeostasis
The stresses which people experience also vary in terms of intensity (low intensity vs. High intensity), duration (short-term vs. long-term), complexity ( less complex vs. More complex) and predictability (unexpected vs. predictable). The outcome of stress depends on the position of a particular stressful experience along these dimensions. Usually more intense, prolonged or chronic, complex and unanticipated stresses have more negative consequences than have less intense, short-term, less complex and expected stresses. An individual’s experiences of stress depend on the physiological strength of that person. Thus, individuals with poor physical health and weak constitution would be more vulnerable than would be those who enjoy good health and strong Constitution. Psychological characteristics like mental health, temperament, and self-concept are relevant to the experience of stress. The cultural context in which we live determines the meaning of any event and defines the nature of response that is expected under various conditions. Finally, the stress experience will be determined by the resources of the person, such as money, social skills, coping style, support networks, etc. All these factors determine the appraisal of a given stressful situation.
Signs and Symptoms of Stress
The way we respond to stress varies depending upon our personality, early upbringing and life experiences. Everyone has their own pattern of stress response So the warning signs may vary, as may their intensity. Symptoms of stress can be physical, emotional and behavioural. Any of the symptoms can indicate a degree of stress which, if left unresolved, might have serious implications.
TYPES OF STRESS
The three major types of stress, viz. physical and environmental, psychological, and social.
- Physical and Environmental Stress
Physical stresses are demands that change the state of the body. One feel strained when overexert itself physically, lack a nutritious diet, suffer an injury, or fail to get enough sleep. Environmental Stresses are aspects of the surroundings that are often unavoidable such as air pollution, crowding, noise, heat of the summer, winter cold, etc. Another group of environmental stresses are catastrophic events or disasters such as fire, earthquake, floods, etc.
- Psychological Stress
These are stresses that generated minds. These are personal and unique to the person experiencing them and are internal sources of stress. Worry about problems, feel anxiety, or become depressed. These are not only symptoms of stress, but they cause further stress. Some of the important sources of psychological stress are frustration, conflicts, internal and social pressures, etc.
- Social Stress
These are induced externally and result from our interaction with other people. Social events like death or illness in the family, strained relationships, trouble with neighbours are some examples of social stresses. These social stresses vary widely from person to person.
Sources of Stress
A wide range of events and conditions can generate stress. Among the most important of these are major stressful life events, such as death of a loved one or personal injury, the annoying frequent hassles of everyday life and traumatic events that affect the lives.
Life Events Changes, both big and small, sudden and gradual affect the life from the moment a person born.
- Hassles
These are the personal stresses we endure as individuals, due to the happenings in our daily life, such as noisy surroundings, commuting, quarrelsome neighbours, electricity and water shortage, traffic snarls, and so on. The more stress people report as a result of daily hassles, the poorer is their psychological well-being.
- Traumatic Events
These include being involved in a variety of extreme events such as a fire, train or road accident, robbery, earthquake, tsunami, etc. The effects of these events may occur after some lapse of time and Sometimes persist as symptoms of anxiety, flashbacks, dreams and intrusive thoughts, etc.
EFFECTS OF STRESS
There are four major effects of stress associated with the stressed state, viz. emotional, physiological, cognitive, and behavioural.
- Emotional Effects : Those who suffer from stress are far more likely to experience mood swings, and show erratic behaviour that may alienate them from family and friends. Some examples are feelings of anxiety and depression, increased physical tension, increased psychological tension and mood swings.
- Physiological Effects : When the human body is placed under physical or psychological stress, it increases the production of certain hormones, such as adrenaline and cortical. These hormones produce marked changes in heart rate, blood pressure levels, metabolism and physical activity Examples of physiological effects are release of epinephrine and nor -epinephrine, slowing down of the digestive system, expansion of air passages in the lungs, increased heart rate, and constriction of blood vessels.
- Cognitive Effects: If pressures due to stress continue, one may suffer from mental overload. This suffering from high level of stress can rapidly cause individuals to lose their ability to make sound decisions.
- Behavioural Effects: Stress affects our behaviour in the form of eating less nutritional food, increasing intake of stimulants such as caffeine, excessive consumption of cigarettes, alcohol and other drugs such as tranquillisers etc. Tranquillisers can be addictive and have side effects such as loss of concentration, poor coordination, and dizziness. Some of the typical behavioural effects of stress seen are disrupted sleep patterns, increased absenteeism, and reduced work performance.
Stress and Health
People who are unhappy in their personal lives fall sick more often than those who are happy and enjoy life. Chronic daily stress can divert an individual’s attention from caring for herself or himself. When stress is prolonged, it affects physical health and impairs psychological functioning. People experience exhaustion and attitudinal problems when the stress due to demands from the environment and constraints are too high and little support is available from family and friends. The physical exhaustion is seen in the signs of chronic fatigue, weakness and low energy. The mental exhaustion appears in the form of irritability, anxiety, feelings of helplessness and hopelessness. This state of physical, emotional and psychological exhaustion is known as burnout.
General Adaptation Syndrome
General Adaptation Syndrome (GAS). According to him, GAS involves three stages: alarm reaction, resistance, and exhaustion.
1. Alarm reaction stage : The presence of a noxious stimulus or stressor leads to activation of the adrenal pituitary- cortex system. This triggers the release of hormones producing the stress response. Now the individual is ready for fight or flight.
2. Resistance stage : If stress is prolonged, the resistance stage begins. The parasympathetic
nervous system calls for more cautious use of the body’s resources. The organism makes efforts to cope with the threat, as through confrontation.
3. Exhaustion stage : Continued exposure to the same stressor or additional stressors drains the body of its resources and leads to the third stage of exhaustion. The physiological systems involved in alarm reaction and resistance become ineffective and susceptibility to stress-related diseases such as high blood pressure becomes more likely.
Stress and the Immune System
Stress can cause illness by impairing the workings of the immune system. The immune system guards the body against attackers, both from within and outside. Psychoneuroimmunology focuses on the links between the mind, the brain and the immune system. It studies the effects of stress on the immune system. The white blood cells (leucocytes) within the immune system identify and destroy foreign bodies. (antigens) such as viruses. It also leads to the production of antibodies. There are several kinds of white blood cells or leucocytes within the immune system, including T cells, B cells and natural killer cells. T cells destroy invaders, and T-helper cells increase immunological activity. It is these T-helper cells that are attacked by the Human Immuno Deficiency Virus (HIV), the virus causing Acquired Immuno Deficiency Syndrome (AIDS). B cells produce antibodies. Natural killer cells are involved in the fight against both viruses and tumours. Stress can affect natural killer cell cytotoxicity, which is of major importance in the defence against various infections and cancer. Reduced levels of natural killer cell cytotoxicity have been found in people who are highly stressed, including students facing important examinations, bereaved persons, and those who are severely depressed. Studies reveal that immune functioning is better in individuals receiving social support.
Lifestyle
Stressed individuals may be more likely to expose themselves to pathogens, which are agents causing physical illness. People who are stressed have poor nutritional habits, sleep less and are likely to engage in other health risking behaviours like smoking and alcohol abuse. Such health impairing behaviours develop gradually and are accompanied by pleasant experiences temporarily.
COPING WITH STRESS
Coping is a dynamic situation-specific reaction to stress. It is a set of concrete responses to stressful situations or events that are intended to resolve the problem and reduce stress. The way we cope with stress often depends on rigid deep-seated beliefs, based on experience. Individuals show consistent individual differences in the coping strategies they use to handle stressful situations. These can include both overt and covert activities. The three coping strategies given-
- Task-oriented Strategy : This involves obtaining information about the stressful situation and about alternative courses of action and their probable outcome; it also involves deciding priorities and acting so as to deal directly with the stressful situation.
- Emotion-oriented Strategy : This can involve efforts to maintain hope and to control one’s emotions; it can also involve venting feelings of anger and frustration, or deciding that nothing can be done to change things.
- Avoidance-oriented Strategy : This involves denying or minimising the seriousness of the situation; it also involves conscious suppression of stressful thoughts and their replacement by self-protective thoughts.
Coping refers to constantly changing cognitive and behavioural efforts to master, reduce or tolerate the internal or external demands that are created by the stressful transaction. Coping serves to allow the individual to manage or alter a problem and regulate the emotional response to that problem. Coping responses can be divided into two types of responses, problem-focused and emotion focused.
Problem-focused strategies attack the problem itself, with behaviours designed to gain information, to alter the event, and to alter belief and commitments. They increase the person’s awareness, level of knowledge, and range of behavioural and cognitive coping options. They can act to reduce the threat value of the event.
Emotion-focused strategies call for psychological changes designed primarily to limit the degree of emotional disruption caused by an event, with minimal effort to alter the event itself. While both problem-focused and emotion-focused coping are necessary when facing stressful situations, research suggests that people generally tend to use the former more often than the latter.
STRESS MANAGEMENT TECHNIQUES
Stress is a silent killer. It is estimated to play a significant role in physical illness and disease. Hypertension, heart disease, ulcers, diabetes and even cancer are linked to stress. Due to lifestyle changes stress is on the increase.
Some of these techniques are:
Relaxation Techniques : It is an active skill that reduces symptoms of stress and decreases the incidence of illnesses such as high blood pressure and heart disease. Usually relaxation starts from the lower part of the body and progresses up to the facial muscles in such a way that the whole body is relaxed. Deep breathing is used along with muscle relaxation to calm the mind and relax the body.
Meditation Procedures: The yogic method of meditation consists of a sequence oflearned techniques for refocusing of attention that brings about an altered state of consciousness. It involves such a thorough concentration that the meditator becomes unaware of any outside stimulation and reaches a different state of consciousness.
Biofeedback: It is a procedure to monitor and reduce the physiological aspects of stress by providing feedback about current physiological activity and is often accompanied by relaxation training. Biofeedback training involves three stages : developing an awareness of the particular physiological response, e.g. heart rate, learning ways of controlling that physiological response in quiet conditions; and transferring that control into the conditions of everyday life.
