Effects of Stress Essay

What he observed was adrenaline and glucocorticoids dictate the stress response. The physiological changes to the body during the stress response are the lungs work overtime to deliver oxygen to the bloodstream, and the heart races to pump oxygen throughout the body so muscles respond instantly. The blood pressure needs to go up to deliver energy. The body will turn off anything that is not essential at that moment. Examples

The definition of stress according to the Oxford dictionary is “A state of mental or emotional strain or tension resulting from adverse or demanding circumstances.”

There are three different theories that are used when talking about how we react to stress through the physiological aspect or the psychological aspect. The first is part of the physiological aspect of stress called the Cannon Fight or Flight theory which was proposed in 1914. Fight or Flight response is a physiological stress response that evolved to help organisms to survive immediate danger. The theory states that when an organism, human being or animal, faces imminent danger (acute stressor) the body arouses quickly and is ready to act via two different systems. They are the sympathetic nervous system and the endocrine system. The sympathetic nervous system stimulates the adrenal medulla which is part of the endocrine system and is the region that produces the hormones such as adrenaline and noradrenaline. These hormones increase heart rate, blood flow, and glucose levels to prepare the body for an emergency. This response from the body suggests that the body knows how to protect itself and reach homeostasis. These two systems work together to either fight against the danger or flight away from the danger. Lord, King and Pfister in 1976 studied the Fight or Flight response in animals through a very unethical study. They administered chemicals on male hooded Wistar rats which inhibited the neurotransmitters from functioning normally. This made it very difficult for the rats to escape an electric shock. The results of the study suggest that the Flight or Fight response

In an acute stressor, the immune system is heightened. But is suppressed in a chronic stressor. In this situation the cortisol levels rise, and weaken the immune system. This weaken system can make the human body more susceptible to serious disease, infections

When put under stress, both humans and baboons have cortisol and adrenaline found in their blood. These hormones are critical for survival, and other physical changes in the body such as a racing heart, increased blood pressure, and quickly responding muscles are all present when the body is put under stress. However, in regard to humans, these same physical responses can occur when the body is not in a life in death situation. Instead, it is common for psychological stresses such as public speaking, taking a test, paying taxes, or driving a vehicle to invoke the same physiological responses as someone in a critical situation. This can be unhealthy for the human body, as many people can get worked up over multiple stressors in one day,

When stressed, we have and increase in heart rate, muscles tense, breathing quickens and you may start to sweat. ¹

The nervous system is activated, releasing hormones that prepare the body to take off or fight. This is called the "fight or flight" response. Your body’s heartbeat speeds up, your rate of breathing increases, muscles are tense, and you start to sweat. This is short-term and temporary (acute stress), and usually your body recovers quickly. Long term stress, when stress stays activated for ‘n long period (chronic stress), can lead to serious health problems. The constant rush of stress hormones will wear your body down, causing it to age quicker and be more prone to illnesses. When stress is not properly addressed it can lead to serious health

Once your brain has decided there’s a danger, in stressful situations, it sends immediate nerve signals down your spinal cord to the pituitary gland and all the ways to the kidneys where your adrenal gland resides, which is how adrenaline is released. Once released, adrenaline increases the amount of sugar in your blood, increases your heart rate and raises your blood pressure. The brain’s hypothalamus also sends signals to your pituitary gland, which allows the body to release Cortisol: Cortisol is a stress response that allows the blood and sugar pressure to remain high, which helps when escaping from danger. For instance, in an interview, which presents a challenge, simulated the same biological reaction that a threat to your life does.

When faced with a life threatening position, human responses can be put to the ultimate test. These responses protect humans from threatening attacks, possible natural disasters, or mobilize the body during other periods of threatening times. Additionally, this sense is triggered when adrenaline, cortisol, endorphins, and many other natural chemicals are released into the body. Which can help to protect, and defend during what might occur next. “When presented with an immediate stressor, the body releases adrenaline, noradrenaline, and cortisol. Good Therapy said that, “The heart rate elevates and blood is directed away from the organs and toward the arms and legs to enable fighting or fleeing”(Good.)

Stress, America’s silent killers. Stress affects people of all ages, ethnicities and genders. Due to its complex nature the concept of stress is constantly being studied. Extensive research has discovered that stress can cause both psychological, and physiological issues. I’m writing on the concept of stress because it is something I have been able to identify with as a transitioning college student. It is also something I know many people can identify with but don’t necessarily know how to deal with.

Stress affects the body in many different ways. Many doctors estimate that stress is involved in more than half of all illnesses (Sapolsky, 21). Stress may cause or prolong an illness or increase its severity. Epinephrine and norepinephrine are hormones that are released during a stress reaction that affect organs throughout the body. As a result from the hormones being secreted, the heart begins to beat more rapidly, muscle tension increases, blood pressure raises, and heavy breathing may occur. This reaction is known as the fight-or-flight response. The fight-or-flight response energizes the body to either confront or flee from a threat. Heredity, learning, and injuries all play a role in determining where or when a stress related illness may occur in a particular individual (Sapolsky, 22).

Hans Selye (1982) points out that few people define the concept of stress in the same way or even bother to attempt a clear-cut definition. According to Selye, an important aspect of stress is that a wide variety of dissimilar situations are capable of producing the stress response such as fatigue, effort, pain, fear, and even success. This has led to several definitions of stress, each of which highlights different aspects of stress. One of the most comprehensive models of stress is the Biopsychosocial Model of Stress (Bernard & Krupat, 1994). According to the Biopsychosocial Model of Stress, stress involves three components: an external component, an internal component, and the interaction between the external and internal components.

According to Elkin and Rosch (1990) workplace related stress in a major problem in the U.S. and it creates a major expense for corporations. Koeske, Kirk, and Koeske (1993) indicate that all jobs have some level of stress but jobs that are in the human services have additional stressors because they “derive from intense involvement in the lives of others”. (p.319). They also refer to the type of stress experienced by individuals working in human services as “burnout” (Koeske, Kirk, and Koeske, 1993, p.319). Another factor that can influence our stress level is how we handle life’s demands. There are different ways of reacting to the situations we face every day of our lives. We have all heard of expressions such as ‘road rage’ and ‘going postal’. These are terms that we have come to identified with violent reactions to stressors caused by situations all of us face every day. How many of us have experiences in the road that

Everybody has at least one thing in common. Can you guess what it is? If you guessed, heartbreak, you’re right, but that’s not the answer I’m looking for. The correct answer is stress. Everyone has stress in his or her life at one point or another. It’s one of many inevitable parts of life. Whether it’s busting out a research paper for Psychology at the last minute, expecting your first child to be born, to making sure you’re up in time to catch the Saturday morning cartoons, it’s clearly evident that everyone goes through stress. The real question is, how is stress handled in our society? A person is defined by how they handle the stressors in their lives and how they overcome stressful moments. This paper will explore the aspects of

      Stress can affect all aspects of one's mind and body.  Behaviorally, stress can cause anger, excessive crying, depression, apprehension, increased alcohol use, mood swings, and even suicide.  It can cause problems physically as well.  Anorexia, fatigue, trembling, loss of appetite, and headaches are just a few of the symptoms that overly stressed individuals may experience (Morrison 2).
