Stress defines a cluster of psychophysiological responses aimed at enabling resources to solve difficult situations, as well as restoring and maintaining homeostasis in the body. Stress is a combination of physiological, neuroendocrine, behavioural and emotional responses to new or threatening stimuli and serves as a protective adaptation of the body under physiological conditions. In accordance with the effect on the body, beneficial and negative stress is distinguished. Stress can be divided into “chronic” and “acute”. The intensity of the physiological response to a stressor is highly individual and situationally dependent. Many variables, including personal attributes, coping strategies, social support, and past experiences may modify the physiological stress response in any given situation and can account for the different response of people exposed to the same stressor. Intense and persistent stress can lead to psychological and pathological body injury. Stress has a significant impact on different brain regions, including the hippocampus, hypothalamus, amygdala etc. Depression, anxiety, cognitive deficits, and even stress-induced mental diseases are closely related to functional and structural damage of the related brain regions. Repetitive daily acute stress can be associated with different diseases, first of all cardiovascular diseases, which affect quality of life and can cut short life expectancy. Timely treatment is required to prevent progression of early stress reactions to chronic post-traumatic stress disorder, especially in individuals at high risk. Advanced stress and anxiety management interventions include non-pharmacological and pharmacological treatments.
