A stressor is a chemical or biological agent, environmental condition, external stimulus or an event that causes stress to an organism. Psychologically speaking, a stressor can be events or environments that an individual would consider demanding, challenging, and or threaten the individual’s safety. An event that triggers the stress response may include: environmental stressors (hypo or hyperthermic temperatures, elevated sound levels, over-illumination, overcrowding) daily stress events (e.g., traffic, lost keys, money, quality and quantity of physical activity) life changes (e.g., divorce, bereavement) workplace stressors (e.g., high job demand vs. low job control, repeated or sustained exertions, forceful exertions, extreme postures, office clutter) chemical stressors (e.g., tobacco, alcohol, drugs) social stressor (e.g., societal and family demands)Stressors have physical, chemical and mental responses inside of the body. Physical stressors produce mechanical stresses on skin, bones, ligaments, tendons, muscles, and nerves that cause tissue deformation and in extreme cases tissue failure. Chemical stresses also produce biomechanical responses associated with metabolism and tissue repair. Physical stressors may produce pain and impair work performance. Chronic pain and impairment requiring medical attention may result from extreme physical stressors or if there is not sufficient recovery time between successive exposures. A recent study shows that physical office clutter could be an example of physical stressors in a workplace setting. Stressors may also affect mental function and performance. One possible mechanism involves stimulation of the hypothalamus, CRF (corticotropin release factor) -> pituitary gland releases ACTH (adrenocorticotropic hormone) -> adrenal cortex secretes various stress hormones (e.g., cortisol) -> stress hormones (30 varieties) travel in the bloodstream to relevant organs, e.g., glands, heart, intestines -> flight-or-fight response. Between this flow, there is an alternate path that can be taken after the stressor is transferred to the hypothalamus, which leads to the sympathetic nervous system. After which, the adrenal medulla secretes epinephrine. Mental and social stressors may affect behavior and how individuals respond to physical and chemical stressors. Life requires everyone to make sudden and planned adjustments to meet its demands, but the greater the demand comes with a greater adjustment and possibly more stress. Determining the impact of these various stressors allow individuals to decide the relationship between the types of stressors and the degree of distress. Identifying the stressor-stress relationship must involve quantifying the impact of life demands and all stress spurred from it. To do this, subjective measures and objective measures will be used depending on the situation. Individuals determine the degree of adjustment themselves in subjective measures, but a degree of adjustment will be or has already been assigned to the individual in an objective measure. The degrees of adjustment is measured by life change units, where one unit equals a degree of adjustment necessary to cope with the life change. The practice of measuring life change units led to the creation of many scales composed of these units that are tailored to certain life events or situations, such as social readjustment and college students. Once the relationship between the stressor (event) and the stress, the individual can then begin to focus on the stress magnitude and the stress itself. For life events with a lower magnitude of impact, the ability to cope and adjust may not be very complex and relatively brief. But for others, life events with high magnitudes can impact their lives in many ways for an extended amount of time. The various stressors listed above can all have events or stressors that range anywhere from minor to traumatic. Traumatic events are very debilitating stressors, and often times these stressors are uncontrollable. Traumatic events can deplete an individual’s coping resources to an extent where the individual may develop acute stress disorder or even post-traumatic stress disorder. Acute stress disorder is a psychological disorder where a traumatic event that is life-threatening or threatens an injury causes a reaction of fear and helplessness lasting up to four weeks. Post-traumatic stress disorder has symptoms of lasting longer than one month, and the first symptom is a history of experiencing a traumatic event followed with a reaction of intense fear, helplessness, or horror. The traumatic event is persistently reexperienced in one of these ways: recurrent distressing recollections, dreams, flashbacks, illusions, or a sense of reliving the experience, and distress or physical arousal by reminders of this event. The individual suffers from a persistent avoidance of reminders of the event. People who have been abused, victimized, or terrorized are often more susceptible to stress disorders. No matter the magnitude of the stressor and stress, most stressor-stress relationships can be evaluated and determined by either the individual or a psychologist. Without proper attention, stress can produce severe effects on mental health and the immune system, which can eventually lead to effects on the physical body. Therapeutic measures are often taken to help replenish and rebuild the individual’s coping resources while simultaneously aiding the individual in dealing with the current stressor. see more at Wikipedia Check More at http://www.stop-n-shop.spwebhost.com/

In linguistics, and particularly phonology, stress or accent is relative emphasis or prominence given to a certain syllable in a word, or to a certain word in a phrase or sentence. That emphasis is typically caused by such properties as increased loudness and vowel length, full articulation of the vowel, and changes in pitch. The terms stress and accent are often used synonymously in that context but are sometimes distinguished. For example, when the emphasis is produced through pitch alone, it is called a pitch accent, and when produced through length alone, it is called quantitative accent. When caused by a combination of various intensified properties, it is called a stress accent or dynamic accent; English uses what is called a variable stress accent. Since stress can be realized through a wide range of phonetic properties, such as loudness, vowel length, and pitch, which are also used for other linguistic functions, it is difficult to define stress solely phonetically. The stress placed on syllables within words is called word stress or lexical stress. Some languages have fixed stress, meaning that the stress on virtually any multi-syllable word falls on a particular syllable, such as the penultimate (e.g. Polish) or the first (e.g. Finnish). Other languages, like English and Russian, have variable stress, where the position of stress in a word is not predictable in that way. Sometimes more than one level of stress, such as primary stress and secondary stress, may be identified. However, some languages, such as French and Mandarin, are sometimes analyzed as lacking lexical stress entirely. The stress placed on words within sentences is called sentence stress or prosodic stress. That is one of the three components of prosody, along with rhythm and intonation. It includes phrasal stress (the default emphasis of certain words within phrases or clauses), and contrastive stress (used to highlight an item, a word or part of a word, that is given particular focus). see more at Wikipedia Check More at http://christmas.effectsofanxiety.net/

Stress, either physiological or biological, is an organism’s response to a stressor such as an environmental condition. Stress is the body’s method of reacting to a condition such as a threat, challenge or physical and psychological barrier. Stimuli that alter an organism’s environment are responded to by multiple systems in the body. In humans and most mammals, the autonomic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis are the two major systems that respond to stress. The sympathoadrenal medullary (SAM) axis may activate the fight-or-flight response through the sympathetic nervous system, which dedicates energy to more relevant bodily systems to the acute adaptation to stress, while the parasympathetic nervous system returns the body to homeostasis. The second major physiological stress, the HPA axis regulates the release of cortisol, which influences many bodily functions such as metabolic, psychological and immunological functions. The SAM and HPA axes are regulated by several brain regions, including the limbic system, prefrontal cortex, amygdala, hypothalamus, and stria terminals. Through these mechanisms, stress can alter memory functions, reward, immune function, metabolism and susceptibility to diseases. Definitions of stress differ. One system suggests there are five types of stress labeled “acute time-limited stressors”, “brief naturalistic stressors”, “stressful event sequences”, “chronic stressors”, and “distant stressors”. An acute time-limited stressor involves a short-term challenge, while a brief natural stressor involves an event that is normal but nevertheless challenging. A stressful event sequence is a stressor that occurs and then continues to yield stress into the immediate future. A chronic stressor involves exposure to a long-term stressor, and a distant stressor is a stressor that is not immediate. see more at Wikipedia Check More at https://engageshops.com/novelty_inc

stress relievers meaning

In continuum technicians, stress is really a physical variety that expresses the inner makes that neighboring contaminants of a continuing product exert on one another, while strain may be the way of measuring the deformation on the material that is not an actual quantity. For instance, when a stable vertical bar can be supporting an overhead excess weight, each particle inside the bar pushes over the particles right away below it. Whenever a liquid is within a closed box under great pressure, each particle receives forced against by all of the surrounding allergens. The container wall space as well as the pressure-inducing surface area (like a piston) force against them in (Newtonian) effect. These macroscopic causes are actually the internet result of an extremely large number of intermolecular causes and collisions between your contaminants in those substances. Stress is generally represented by way of a lowercase Greek notice sigma (?). Strain in the material may come up by various systems, such as strain as utilized by external pushes to the majority material (just like gravity) or even to its surface area (like contact causes, external strain, or friction). Any pressure (deformation) of a good material generates an interior elastic stress and anxiety, analogous for the reaction force of your spring, that will restore the product to its unique non-deformed point out. In fluids and gases, just deformations that transformation the quantity generates persistent stretchy stress. However, when the deformation is steadily changing as time passes, even in liquids there will most likely end up being some vicious anxiety, opposing that adjustment. Elastic and viscous strains are usually merged under the label mechanical stress. The significant strain may exist even though deformation is usually negligible or non-existent (a standard assumption when modeling the movement of normal water). Anxiety may exist inside the absence of exterior forces; many of these built-in stress is essential, for instance, in prestressed concrete and tempered glass. Stress can also be imposed on the material minus the application of online forces, for instance by improvements in heat range or chemical structure, or by outside electromagnetic grounds (as with piezoelectric and magnetostrictive supplies). The relationship between mechanical pressure, deformation, as well as the rate of modification of deformation could be very sophisticated, although a linear approximation could be adequately used if the volumes are small plenty of. Stress that surpasses certain strength limitations of the content can lead to long-lasting deformation (such as for example plastic move, fracture, cavitation) as well as modify its crystal construction and chemical structure. In a few branches of an anatomist, the term stress and anxiety is occasionally found in a looser good sense to be a synonym of “internal force”. For instance, in the examination of trusses, it could refer to the full total grip or compression pressure functioning on a beam, as opposed to the force separated by the region of its cross-section. see more at Wikipedia Check More at http://www.stop-n-shop.spwebhost.com/

A stress position, also known as a submission position, places the human body in such a way that a great amount of weight is placed on just one or two muscles. For example, a subject may be forced to stand on the balls of his feet, then squat so that his thighs are parallel to the ground. This creates an intense amount of pressure on the legs, leading first to pain and then muscle failure. Forcing prisoners to adopt such positions is an enhanced interrogation technique (torture technique) used for extracting information. see more at Wikipedia Check More at http://personal.effectsofanxiety.net/

In psychology, anxiety is an experience of pressure and pressure. Anxiety is a kind of psychological pain. Smaller amounts of stress could be desired, beneficial, and also healthy. Positive anxiety helps increase athletic performance. In addition, it plays one factor in motivation, version, and a reaction to the environment. Extreme amounts of tension, however, can lead to bodily harm. Tension can raise the threat of strokes, heart strikes, ulcers, and emotional illnesses such as for example depression. Stress could be external and linked to the surroundings, but can also be caused by interior perceptions that result in an individual to see anxiety or additional negative emotions bordering a situation, such as for example pressure, soreness, etc., that they then deem nerve-racking. Humans experience tension or perceive stuff as threatening if they do not think that their information for dealing with obstacles (stimuli, persons, circumstances, etc.) happen to be plenty for what the instances demand. When folks think the needs being positioned on them go beyond their capacity to cope, then they perceive stress. see more at Wikipedia Check More at http://loseweight.effectsofanxiety.net/

Shear stress, often denoted by τ (Greek: tau), is the component of stress coplanar with a material cross-section. Shear stress arises from the force vector component parallel to the cross-section of the material. Normal stress, on the other hand, arises from the force vector component perpendicular to the material cross-section on which it acts. Shear stress arises from shear forces, which are pairs of equal and opposing forces acting on opposite sides of an object. see more at Wikipedia Check More at http://personal.effectsofanxiety.net/
