Effects of Stress

Take a look at the various harmful effects of stress and understand how it affects your body.

Effects of Stress

Effects of stress on health and physiological functioning

1 Emotional Effect

People who suffer from stress are likely to experience mood swings and show erratic behaviour that may alienate them from family and friends. Decreasing self-confidence can lead to serious emotional troubles. Some examples are anxiety, depression, and physical tension. Example -examination anxiety.

2 Cognitive Effect

If pressure due to stress continues, one may suffer from mental overload. This suffering from a high level of stress can rapidly cause the individual to lose their ability to make sound decisions. For example- poor concentration reduced short-term memory capacity.

3 Behavioral Effect

Stress affects our behaviour in the form of eating less nutritional food, intake a stimulant like caffeine, cigarettes, alcohol etcetera. Such substances have side effects is the loss of concentration, poor coordination, and dizziness. Example- disrupted sleep pattern, reduce work performance, absenteeism.

4 Physiological Effect

When the body is placed under physical slash physiological stress, it increases the production of certain hormones, such as adrenaline and cortisol. These hormones produce mark changes in heart rate, metabolism. Example- increase head rate, and slow digestion.

Stress and health

How does stress reduce such physiological defects? The following process can determine the precise mechanisms involved: by training our resources and keeping us off balance physiologically, stress upsets are complex internal chemistry. hey in particular it may interfere with the efficient operation of our immune system the mechanism through which our bodies protect themselves from diseases. Foreign substances that enter our bodies are known as antigens. When they appear, certain types of white blood cells lymphocytes begin to multiply. These attack the antigens are often destroying them. Other white blood cells produce antibodies, chemical substances that are combined with antigens and so neutralized am.


1 Prolonged exposure to stress seems to disrupt the system. in studies with animals, subjects exposed to inescapable shocks demonstrate reduce the production of lymphocytes relative to subjects exposed to shock from which they can escape.

2 Another research suggested that a variety of stressors, including disrupted hey interpersonal relationships, loneliness, academics pressure, daily hassles can interfere with the immune system.

3 Cohen and his colleagues (1992) assessed the effects hey of social stability on the immune system of monkeys. In the year preceding the study, monkeys were made to live in unchanging stable conditions. When the study began, they were made to live either in stable or unstable conditions for the next 26 months. Social groups were reorganised and frequently in unstable conditions. Hey, researchers observed in assess the time the group spent in various forms of interaction including afflictive behaviour. They wanted to study this to find that if social support word stress buffer, that the monkeys in the group would engage in the least amount of initiative behaviour and would experience a negative impact on the immune system. The results confirm these predictions.

4 Human study

People who were divorced or separated from their spouses often experience reduced functioning in certain aspects of the immune system, compared to individuals who are happily married.

5 Burnout

People experience exhaustion and attitudinal problems when the stress is too high and little support from family and friends. Physical exhaustion is seen in stages of chronic fatigue, low energy etcetera. Mental exhaustion appears in the form of inability, anxiety etcetera. The stages of physical, emotional, and physiological exhaustion are known as burnout full typically occurring as a result of the long-term involvement of people in a situation, which may be emotionally demanding.

Stress and task performance

Psychologists believed that stress improves performance in a wide range of tasks. They have that the relationship between stress and task performance takes the form of an upside-down you: at the first performance, improves are stressing raises, presumably because the stresses arousing or energising. Beyond some point do stress becomes distracting and performance drops.

While this relation may hold under some conditions, growing evidence suggests that even low or moderate levels of stress can interfere with task performance. First, even relatively mild levels of stress can be distracting. People experiencing stress focus on the unpleasant feelings and emotions it involves rather than the task at hand. Second, prolonged or repeated exposure to mild stresses exert harmful effects on health, and health problems interfere with task performance. Finally, as arousal increases, task performance may rise at first, but then at some point, it fails the precise location of this turning or inflection point seems to depend to an important extent on the complexity of the task performed. Greater complexity the lower level of arousal at which the downtown in performance occurs.

Together these factors help explain why even moderate levels of stress may interfere with many types of performance. However, stress does not always produce adverse effects. For example, people sometimes do seem to rise to the occasion and in turn in sterling performances at times when stress is intense. Perhaps the most reasonable conclusion then is that all those can interfere with task performance in many situations, its precise effects depend on many different factors, such as the complexity of the task being performed and the personal characteristics of the individuals involved.
