Stress, whether physiological, biological or psychological, is an organism's response to a stressor such as an environmental condition. [1] Stress is the body's method of reacting to a condition such as a threat, challenge or physical and psychological barrier. There are two hormones that an individual produces during a stressful situation ...
In continuum mechanics, stress is a physical quantity that describes forces present during deformation. For example, an object being pulled apart, such as a stretched elastic band, is subject to tensile stress and may undergo elongation. An object being pushed together, such as a crumpled sponge, is subject to compressive stress and may undergo ...
There is no doubt that stress is a part of everyday life, but too much can have detrimental impacts on people’s physical and mental health. What people should know about stress, according to a ...
Stress hormones are secreted by endocrine glands to modify one's internal environment during the times of stress. [1] By performing various functions such as mobilizing energy sources, increasing heart rate, and downregulating metabolic processes which are not immediately necessary, stress hormones promote the survival of the organism. [1]
Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...
In psychology, stress is a feeling of emotional strain and pressure. Stress is a type of psychological pain.Small amounts of stress may be beneficial, as it can improve athletic performance, motivation and reaction to the environment.
Chronic stress is the physiological or psychological response induced by a long-term internal or external stressor. [1] The stressor, either physically present or recollected, will produce the same effect and trigger a chronic stress response. [1] There is a wide range of chronic stressors, but most entail relatively prolonged problems ...
Stress (biology), an organism's response to a stressor such as an environmental condition. Stress (mechanics), the internal forces that neighboring particles of a continuous material exert on each other. Oxidative stress, an imbalance of free radicals. Psychological stress, a feeling of strain and pressure.
