“ Up for the big promotion this week?” or “maybe midterms have you freaking out?” Rather you are feeling the effects of eustress: a beneficial stress or “good stress”, or you are just distressed and filled with anxiety, sorrow or pain. When the stress comes in to our lives, it is important that we pay attention. So, what is stress? Stress is defined as a series of mental and physiological responses and adaptations to a real or perceived threat to one’s well being. It can come from joyous moments, like the birth of a child. Freighting events like asking your crush out, and things that are in the unknown like ones future. It can affect any one, from people that are label as Type A personality that are competitive, outgoing, ambitious, impatient to those that are more relaxed, reflective and innovated, which are people with Type B personality, they …show more content…

This state of equilibrium is ideal for the bodies, however, adaptive evolutionary changes have made it that when stressor are trigger our bodies respond to ensure survival. This change is referred to as The General Adaption Syndrome characterized by Hans Selye in 1936. The General Adaption syndrome or (GAS) is the pattern followed in the physiological response to stress, consisting of three phases: alarm, resistance, and exhaustion phase. In the alarm phase the stressor disputes body’s stability, temporarily lowering resistance, this phase is also know as the Fight or Flight phase, meaning that your body is preparing to fight or run after the autonomic nervous system (ANS) is triggered. The ANS has two branches to its system the Sympathetic System: which causes the body to become energized, and is responsible for the release of the stress hormones epinephrine (which relives pain) and cortisol (helps store nutrients). The second branch of the ANS is Parasympathetic System, which slows the system down when

Often called the fight or flight reflex, stress has been known to save people’s lives, whether it be on a battlefield or some dangerous situation back home. Too much stress ultimately leads to health problems, but too little stress isn’t good for us either. When we go too long without a sharp stimulating response, the body loses its ability to handle stress properly (Tom Scheve, 2009). Somewhere between too much, and too little stress can actually be good for you, helping you perform under pressure. It is when someone cannot turn off that fight or flight feeling that it begins to show its negative effects.

When presented with uncertainty about a decision, or perceiving a threat to survival such as having to swing around a horizontally metal 1-inch pole’s axis completely with nothing to hold on to other than your hands, physiological changes in the body occur (known as the ‘fight-or-flight’ response) that are known to excite the sympathetic-division of the autonomic nervous-system into a ‘hyper-aroused’ state which is described to be “a non-specific response” to stress by Selye (1979) [reference to textbook case study on pg243]. Continuing on with Selye’s pioneered research on ‘stress’, he was able to distinguish between two different responses to ‘stress’ – a negative response would be labeled ‘distress’ and can be seen in worrying situations;

1. Provide at least two examples of the opposite effects of the sympathetic and parasympathetic divisions of the nervous system. Parasympathic divisions slows the heart rate and breathing in someones body and the sympathy makes these functions work. 2.

According to Martini, F., Tallitsch, R., Nath, J., (2018), the ANS functions outside of our conscious awareness and makes routine adjustments in our body’s systems (Martini, Tallitsch, & Nath, 2018, p. 450). The autonomic nervous system helps maintain the homeostasis of our bodies by regulating body temperature and coordinating cardiovascular, repertory, digestive, excretory, and reproductive functions. Efferent axons innervate the visceral organs and the efferent nerve fibers and ganglia of the ANS organize in two systems or divisions. The sympathetic division and the parasympathetic division. The sympathetic division is most active during times of stress, exertion, or emergency, also known as “flight or fight”.

Sympathetic and Parasympathetic Nervous System Salma Ewing Feb 15, 2018 The sympathetic and parasympathetic nervous system are two divisions of the autonomic nervous system of the body. They are very closely related and coordinated with each other and regulate the unconscious functions of the body. The autonomic nervous system is responsible for our involuntary reactions and controls our heart beat, digestive processes, blood flow and hormone production. This means that we can’t consciously control whether our heart beats or not.

The above diagram is a model of the general adaptation syndrome (GAS) devised by Hans Selye (1976). The model was made for the intended purpose of explaining stress response, how age can affect the manner in which stress affects the body, and also how illnesses can be caused by continuous stress exposure. The model is described as general it is only based off agents that have a standard and extensive effect on the body. Stress can disrupt homeostasis in our bodies, by altering the manner in which our body functions. Stress can also reduce our lifespans by speeding up the process of aging.

All that we do, we are bound to encounter stress. Stress can be defined as a state of mental or emotional strain or tension resulting from adverse or very demanding circumstances. Whenever one is facing difficulty ,suffering anxiety, or feeling worried,stress will immediately take over. Stress has been, and will remain to be, a natural part of our daily routine. This causes many to underestimate its overall effects.

In the alarm phase the body recognizes the stressor and responds by preparing for fight or flight. The body’s reactions are numerous and complex and will be briefly summarized. The hypothalamus located in the brain sends a message to the pituitary gland to release its hormones and this triggers the adrenal glands to release adrenaline” (Castro, 2015, p.377-382). The physiological symptoms that I have experienced include anxiety, tension, and worry and then these leads to the physical reactions of stress which include the alarm phase where the “body prepares for fight or flight, the resistance phase when the body attempts to return to homeostasis, and the third phase of exhaustion occurs when he body remains in a state of high stress for an extended period of time and is unable to repair damage” (Zastrow, 2015, p.377-380).

Sympathetic (SNS) and Parasympathetic (PNS) Nervous Systems. It makes the soldiers feel aroused (the stressors) in a hectic situation (SNS), only to be returned to homeostasis by the PNS a short period of time after the combat ends. Third, the delayed phase of intensive combat is where unexplainable symptoms like social withdrawal, irritability, and persistent anger occur after the intense combat stressors resulting in substance abuse in a soldier’s life. Fourth, the chronic phase of intensive combat is where soldiers have continued intrusive symptoms with an infusion of existential questions and mood disturbances. This is because many chronic trauma victims lose their sense of self, commonly called dissociation.

3. Review of literature 3.1 Stress and its types: Stress is an essential mediator of human behaviour. Immediate physiological response to any type of stressor facilitates survival of the species at its maximum. Despite of normal homeostatic regulatory mechanism, the stress responses can become maladaptive. Chronic stress, for example immobilization, exposure to noise, irradiations, psychological stress can leads to a host of adverse health consequences, including cardiovascular diseases, neurodegeneration, obesity, depression and early ageing (McEwen et al, 2004).

INTRODUCTION Stress is a word derived from Latin word “Stingere” meaning to draw tight. (Mojoyinola, 2008) Stress is your body’s way of responding to any kind of demand or threat. When you feel threatened, your nervous system responds by releasing a flood of stress hormones, and including adrenaline and cortisol, which rouse the body for emergency action. Your heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and your senses become sharper. These physical changes increase your strength and stamina, speed your reaction time, and enhance your focus.
