Stress is a psychological and physiological response that occurs when an individual perceives that the demands of a situation exceed or threaten their ability to cope. In behavioural sciences, stress is understood as an interaction between an individual and the environment. It is not always harmful because a moderate level of stress can motivate a person, improve alertness and encourage effective performance. However, prolonged, intense, or poorly managed stress can negatively affect physical health, psychological well-being, behaviour and social relationships. Stress can arise from many sources, including work pressure, academic demands, financial difficulties, family problems, illness, relationship conflicts, major life changes and environmental conditions. The experience of stress varies from person to person because individuals differ in personality, coping abilities, social support, past experiences and perception of the situation. One important classification is acute stress. Acute stress is short-term stress that occurs in response to an immediate challenge, threat or unexpected event. Examples include facing an examination, giving a public presentation, narrowly avoiding an accident or dealing with an urgent work assignment. The body's stress response is activated rapidly, preparing the person to deal with the situation. Heart rate and breathing increase, muscles become tense and attention becomes focused. Once the stressful event is over, the body generally returns to its normal state. Acute stress can sometimes be beneficial because it increases alertness and energy and helps an individual respond quickly to challenges. Episodic acute stress occurs when a person experiences acute stress repeatedly and frequently. Individuals who constantly face deadlines, conflicts or emergencies may experience this form of stress. People with highly demanding lifestyles, excessive workloads or a tendency to worry continuously may be particularly vulnerable. They may become irritable, impatient, anxious and emotionally exhausted. Frequent headaches, digestive problems, sleep disturbances and high blood pressure may also occur. If episodic acute stress continues for a long period, it can interfere with relationships, work performance and overall quality of life. Chronic stress is long-lasting stress resulting from persistent difficulties or circumstances. It may develop because of prolonged financial problems, an unhealthy work environment, family conflict, unemployment, chronic illness, social insecurity or continuing academic and occupational pressure. Unlike acute stress, chronic stress does not disappear quickly because the stressful situation remains present. Continuous activation of the
