HEAT STRESS
Heat stress can be a serious problem in hot working environments. The body temperature for a human must be maintained all the time, regardless of work load or adverse environmental conditions. A drastic increase in body temperature can result in death. The body initially responds to heat by sweating and by circulating blood closer to the skin's surface to lower the main body temperature.

High temperatures, high humidity, sunlight, and heavy workloads increase the heat stress. Too much heat can also make workers lose their concentration or become fatigued and thus increases the chance of accidents and injuries.
This heat stress may lead to the following:
Heat Rash: Is an early signal of potential heat stress. It is commonly associated with hot, humid conditions in which skin and clothing remain humid. Heat rash may involve small areas of the skin or the entire upper body
Heat syncope: Is characterized by dizziness or fainting while standing still in the heat for an extended period.
Heat Cramps: Symptoms include painful cramps or spasms in the legs, arms, or abdomen. Heat cramps are often caused by a temporary fluid and salt imbalance during hard physical work in hot environments.
Heat Exhaustion which results from the reduction of body water content or blood volume. The condition occurs when the amount of water lost as sweat exceeds the volume of water drunk during the heat exposure. The victim of heat exhaustion may have some or all of the signs or symptoms: heavy sweating; clammy, flushed, or pale skin; weakness; dizziness; nausea; rapid and shallow breathing; headache; vomiting; or fainting.
Cold Stress: When in a cold environment, most of your body's energy is used to keep your internal temperature warm. Over time, your body will begin to shift blood flow from your extremities (hands, feet, arms, and legs) and outer skin to the…...

...Introduction In the following easy I will be discussing how stress can cause health issues. This is one of the leading causes of health issues. Stress causes many problems in our bodies and has continued to grow on day to day bases. While there are many way to cope with stress not all can ease it. There has been study that stress causes heart disease. Stress has been known to cause heart attacks, high blood pressure, high cholesterol, and Coronary heart disease. Coronary heart disease is the clogging of the vessels that nourish the heart muscle; the leading cause of death in North America (Myers, 2011). While stress can control our daily life there are ways to help keep our stress level stay down. Many of time just a simple work out can help relieve stress or just taking a ride on a bike. I choose to use martial arts to help relieve my stress. Since I own a martial arts school it’s very easy for me just to hop in my car and go punch on a bag to help my stress level. Stress can also cause anger problems; if we let our stress bottle up and don’t find ways to release it then eventually we will come (unglued) as a call it. When we are easily angered, verbally aggressive, and anger prone this is what Friedman and Roseman’s call Type A (Myers, 2011). The ones who are easygoing and relaxed people Friedman and Roseman’s call Type B (Myers, 2011). Stress can also cause us to come down with illness or break out with rashes. ...

...the life of human being is full of stress. We respond to stress automatically, mostly out of habit to thousand of events in our lives. When the body react to an event or a situation that is emotionally disturbing and faced with such a situation, then various chemical reactions occur in our body like rise in blood pressure, heart beats, breathing problem and disturbed sleep pattern. A certain amount of stress is required by our mind and body to keep it ticking. But uncontrolled, unrelenting stress is not only harmful to our body, but it can also lead to unwise behavior such as alcohol and tobacco abuse. This in turn places us at even greater risk, health-wise. Life-threatening situations are rare, but our current life styles keep our body in a state of continuous imbalance. In the big urban cities, the urban environment, the fast life of the urban people, various other urban activities like commuting long distances, challenges in relationship and usage of drugs for instant relief result in stress.  There are various group of people who suffer from stress like the office goers, professionals, house wives, school children, drivers and the aged people. Thus it can be said that no people are relieved from stress in one way or another. | | Stress | Stress manifests itself in the form of many psychological and physical problems like anxiety, hopelessness, anger, helplessness, egoism, expectation, tension, constipation, irritation, depression, apathy, frustration, loss of......

...Outline and evaluate research (theories and/or studies) into the role played by personality as a source of stress. (18 marks) Friedman and Rosenman (1974) identified two types of personality that relate to individual responses to stress – type A and type B. Type A personalities are said to be impatient, competitive, ambitious, aggressive, find it hard to relax and have a ‘chronic sense of time urgency’. In contrast, type B personalities are the opposite, being less driven, more easy-going, patient and able to relax. As doctors, Friedman and Rosenman noticed that people with Type A personalities were more prone to heart attacks and coronary heart disease. In order to test this hypothesis scientifically they conducted a longitudinal research project called the Western Collaborative study. They examined 3500 healthy middle-aged men from California. Over a period of 8 1(2 years they assessed the lifestyle and health of these participants using structured interviews and medical examinations. By the end of the study 70% of the men who had developed coronary heart disease (CHD) were type A personalities – twice the number of those with type B personality. Friedman and Rosenman concluded that type A behaviour significantly increased the risk of coronary heat disease. One advantage of the Western Collaborative Study lies in it being longitudinal. It tracked men who were originally healthy and developed CHD during the study rather than using retrospective data (such as......

...Stress When the body is in stress it creates glucocorticoids, which are made in the adrenal glands. These glucocorticoids are epinephrine and cortisol, which both accelerate immune cells to move from the bloodstream into the tissue if needed to fight against an infection, and when the infection is gone, they return the body to homeostasis. When a person is in stress, these glucocorticoids do the same thing as if they were fighting an infection; however, if the body is in constant stress, it will continue to "fight the infection" and will not return the body to homeostasis. This can cause glucocorticoid receptor resistance and can cause the body to develop an even higher risk of depression, upper respiratory infections, diabetes, autoimmune disease, slower healing, and even cardiovascular disease (1). The body's stress response kicks in when you feel there is a possible threat, which is necessary to ensure the best chance of survival. In the brain, the hypothalamus and the pituitary control the stress response. The adrenal glands also aid in controlling stress response by the kidneys. When the brain senses danger, it sends nerve signals down the spinal cord to the adrenal glands telling them to release adrenaline, which then increases the sugar in the blood, the heart rate, and the blood pressure. The hypothalamus sends signals to the pituitary gland telling it to release factors that travel quickly through the blood stream and stimulate the adrenal cortex to produce......

...“Stress” is very difficult to define, it can be thought of as a physical response of the body which presents itself whenever we must adapt to changing conditions. These conditions can be real or perceived, and positive or negative. Everybody endures stress in their lives, but people respond to stress differently. Some people are affected by stress severely which can lead to illness, while other people cope with stress particularly well and are unfazed by it. This can be because of individual differences such as our genes, environment and personality. This essay will aim to explain the relationship between stress and how different personality types are affected by it. Cannon (1929) claimed that stress activates the process to appraise or evaluate and then respond to threats or challenges which threaten us. Stress causes a surge of hormones in your body such as cortisol, adrenaline and noradrenaline. These stress hormones are released to boost your ability to deal with pressures or threats; this can be described as “fight or flight”. Once the pressure or threat has passed then stress hormone levels will return to normal. But if you are constantly under stress or threat then these hormones remain in the body causing the negative effects of stress. The events which can provoke stress are those that are perceived as negative and uncontrollable such as catastrophic events like earthquakes or significant life changes such as divorce (Myers, 2002). Personality......

...Stress By Stress is a mental, emotional, or physical strain caused, e.g. by anxiety or overwork. It may cause such symptoms as raised blood pressure or depression (Encarta Dictionary: English, 2010). Stress is a slippery concept. We sometime use the word informally to describe threats or challenges, and at other times, to describe our responses. Stress is not just a stimulus or a response. It is the process by which we appraise and cope with environmental threats and challenges. Stress arises less from events themselves than from how we appraise them (Lazarus, 1998). Stressful life events are catastrophes, significant life changes, and daily hassles. Catastrophes are unpredictable events, such as car accidents, health problems, and wars. Although people often extend one another with aid as well as comfort during or after such events. Significant life changes are personal change, the death of a loved one, the loss of a job, leaving home for college, marriage, and divorce. Life transitions and insecurities are often keenly felt during young adulthood. Some life changes precede illnesses. Daily hassles consist of finding employment if unemployed, making a good grade on an exam, a good medical report if there is an illness, and handling busy schedules. Some people can shake off hassles, others are driven up the wall by them. People’s difficulties in letting go of unattainable goals is another everyday stressor with health consequences (Miller & Wrosch...

...Virk Nearly everyone experiences stress at some time. Stress produces changes in many body systems; examples include increased heart rate and blood pressure and altered immune function. Stress isn’t always bad. In small doses, it can help you perform under pressure and motivate you to do your best, but excessive stress, left untreated, can lead to anxiety and illness. When you’re constantly running in emergency mode, your mind and body pay the price. Stress can affect all aspects of your life, including your emotions, behaviors, thinking ability, and physical health. No part of the body is immune. But, because people handle stress differently, symptoms of stress can vary. Low energy, headaches, upset stomach, including diarrhea, constipation, aches, pains, and tense muscles, rapid heartbeat, frequent colds and infections, cold or sweaty hands, dry mouth and grinding teeth are some of the physical responses to stress. When we’re stressed, the immune system’s ability to fight off antigens is reduced. That is why we are more susceptible to infections. Hypothalamus, a tiny region at the base of the brain, sets off an alarm system in our body. Through a combination of nerve and hormonal signals, this system prompts our adrenal glands, located top of the kidneys, to release a surge of hormones, including adrenaline and cortisol. Adrenaline increases heart rate, elevates blood pressure and boosts energy supplies. Cortisol, the primary stress hormone, increases sugars......

...Stress is unavoidable and it is not possible to eliminate it from our lives entirely. Life is full of challenges, and a life without some turmoil is not only impossible but is also undesirable. The hassles, deadlines, frustrations, and demands of modern life have made stress so commonplace that it has become a way of life for many people. In small doses, stress can help people perform under pressure and motivate them to do their best. But it is not desirable to constantly be in an emergency mode as the mind and body would have to ultimately pay the price. Stress is a normal physical response to events that make us feel threatened or upset our balance in some way. When a threat is perceived, our nervous system responds by release a flood of stress hormones, including adrenaline and cortisol. These hormones rouse the body for emergency action. As a result, our heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and senses become sharper. These physical changes increases our strength and stamina, speed our reaction time, and enhance our focus, thus preparing us to either fight or flee from the danger at hand. This reaction to a real or imagined danger is called the stress response. The stress response is the body's way of protecting us. When working properly, it helps us to stay focused, energetic and alert. In emergency situations, stress can save our life by giving us extra strength, or for example, spurring us to slam on the brakes to avoid and......

...Managing Stress Have you ever had one of those days where everything seems to go wrong? You wake up late for work and the first thing you do is tumble coffee all over your shirt. You know that today is going to be a upsetting and stressful day. In addition to adults, some children become stressed at some point in their lives. The (“American Institute of stress,” 2014) states that stress Is Americas number 1 health problem and according to (Miller, PhD & Alma PhD, “2014”) Stress is the cause for 75 – 90 percent of all visits to primary care physicians are stress linked. Stress can come from anyplace at any time. Every type of stress has its own personal symptoms. Acute stress, episodic acute stress, and chronic stress are the three types of stress (“American Psychological Association”, 2014, Stress: The different kinds of stress). Each type is very different from each other, but very similar all at the same time. All three types have one main symptom, depression. (“Marriam-Webster Dictionary”, 2014) defines depression as the feeling of hopelessness and inadequacy. Depression can cause its host to feel miserable, sad, blue, unhappy, and/or heartbroken. Over a period of time, stress can cause a varietie of health issues including episodic depression, major depression, chronic depression, or manic depression. But all types of depression started with one or all types of stress. Acute stress is the most common form of stress (Sincero, “2008”). Acute stress occurs when its......

...Extra Credit: Stress Documentary Stress: Portrait of a Killer, an enticing documentary about the effects of stress on the human body and how it shapes society. The documentary tackles various aspects of how stress affects mammals, from studies of baboons in Kenya by a Stanford Neurologist to how humans with different ranks in society react to stress. A key in the documentary of which I found most interesting is how humans find it difficult to turn off the stress response feeling after a stressful event. 30 years ago scientists found out that stress wasn’t the result of just stomach ulcers, but stress itself causes the immune and digestive system to not function properly which causes the bacteria in the stomach to give people the sensation that the ulcers are the reason behind stress. There is various health risks discovered through the study of stress on baboons. The two hormones adrenaline and glucacorcacoids exerted from the baboon’s blood revealed that stress could cause major cardiovascular diseases that can lead to heart attack. Stress revealed increased heart rates and blood pressure, primary a result of damaged artery walls, restrict blood flow and clog blood canals, which can lead to heart attack and death. Other studies observed on obese people showed that stress can lead to dangerous fat cells being stored around the abdomen which causes different reactions to hormone growth and attitude. Dopamine is another hormone discovered to be crucial in turning stress into......

...Name: Yeap Chun Siang Matrix number: BACF 14091155 Stress is a state of mental or emotional strain resulting from demanding circumstances. Stress is a normal part of our life and it is not a totally bad thing. It can motivate us to do our job better and train our determination. However, if we do not handle the stress very well, it becomes long-term stress and it will affect our live seriously. Stress can be divided into two types; work stress and life stress. Work stress means that we are facing some problems in our jobs and works. For example, we are unhappy in our job because of low salary and long working hours. Another example of work stress includes the person is working under dangerous condition. If I were the person, I will be stressful because I have to be very careful in my daily works. If I were careless even one time, I might lose my life at my working places. If I had died, then who is going to take care of my family members? Other than that, most of the employees are having a heavy workload or too much responsibility. Their boss is giving them too much of work and demand them to finish the work very well. Therefore, stress comes into the employees. Life stress means that we are facing some problems in our daily life. People who had divorced or lost their loved one will have stress in their life. They might feel sad and emotional because of heart breaking. Another example is the employee loses his or her job. The salary might support their family......

...Impact of Stress on Academic Success in College Students Ou Jia Yin Student ID: 13209586 New Class -1 James Cook University (JCU) Impact of Stress on Academic Success in College Students The word “stress” is generally used to describe a state of great worry caused by a difficult situation, or something that causes this condition. Anything that poses a challenge or is a menace to our well-being is considered a stress and it can be divided into two parts. There are good stresses that gives people the motivation to do something to make their life more meaningful. Additionally, there are also bad stresses that will negatively affect their mental and physical health. People that suffer from bad stress are usually too hasty, overreact too much and have extremely high expectations for themselves. The most common stress that can be seen in teenagers is Academic Stress. According to the American Psychological Association’s survey (2014), teens routinely reported unhealthy levels of stress, and their average reported stress levels exceed those observed in adults. Teens stress level were reported to be 5.8 on a 10-point scale compared with 5.1 for adults. From this, we can see that nearly all the students, especially college students are being affected by Academic Stress. The causes of Academic stress can be analyzed into several factors. These factors include anxiety, sleep deprivation, situational problems, career direction, and previous life experiences. Thankfully, there...

...head: Stress Living a Stress-Free Life Is it possible to attain a stress free life? Is this a reasonable question to ask? A stress free life seems unimaginable and unattainable. We listen to our doctors whom give us loads of information relating to stress and tell us how to successfully balance your work and home life so that your life can be free from stress, but is there any real way to overcome stressors. If you were to ask 10 people what their definition of stress was I am sure you would get 10 different answers from all 10 different people. The reason for this is because stress varies from person to person and how each person copes with it also tends to vary. To understand stress and how it impacts our physical and mental lives, we must educate ourselves on stress, the effects of stress, the causes of stress, the symptoms of stress and how to manage and cope with stress. Stress can be very debilitating and could impact various aspects of our everyday lives if it is not dealt with and managed effectively. I have been through various bouts of stress throughout my life and I have found different ways to combat it which will be explained later in this research paper. As part of my research, I will define stress, the effects of stress, the cause of stress, the symptoms of stress and how to manage and cope with stress, as well as my own personal experience relating to stress. The ideal solution for everyone is to understand stress so when...

...Stress (psychology), an unpleasant state of emotional and physiological arousal that people experience in situations that they perceive as dangerous or threatening to their well-being. The word stress means different things to different people. Some people define stress as events or situations that cause them to feel tension, pressure, or negative emotions such as anxiety and anger. Others view stress as the response to these situations. This response includes physiological changes-such as increased heart rate and muscle tension-as well as emotional and behavioral changes. However, most psychologists regard stress as a process involving a person's interpretation and response to a threatening event. Stress is a common thing we all experience. We may feel stress when we are very busy, have important deadlines to meet, or have too little time to finish all of our tasks. Often people experience stress because of problems at work or in social relationships, such as a poor evaluation by a supervisor or an argument with a friend. Some people may be particularly vulnerable to stress in situations involving the threat of failure or personal humiliation. Others have extreme fears of objects or things associated with physical threats-such as snakes, illness, storms, or flying in an airplane-and become stressed when they encounter or think about these perceived threats. Major life events, such as the death of a loved one, can cause severe stress. Stress can have both positive and......

...This assignment is based upon stress, the bio-psychosocial approach on how stress can affect health, well-being and the maintenance of homeostasis. There are many definitions of stress but the majority of definitions put emphasis on the relationship between the individual and the environment. This is called the bio-psychosocial approach. When treating patients the Practitioner should take a more holistic approach when determining the type of treatment that is required, this would include taking into account the patients lifestyle, environment and social support. The World Health Organisation states that ‘Health is a state of complete physical, mental and social well being and not merely the absence of disease or infirmity’. (WHO 1948). Stress can be defined as any type of change that causes physical, emotional or psychological strain. However, there are many types of stress and not all types of stress are harmful or negative. One theory is that stress is the result of a persons appraisal process. The assessment of whether personal resources are sufficient to meet the demands of the environment. Stress has been identified as being the individuals ability to adapt to the environment (Lazarus and Folkman 1984; Lazarus and Launer 1978; Pervin 1989). There are two types of stress response which Lazarus (1966) made a distinction between, these are psychological and physiological stress. Lazarus stated that physiological stress is a response to a physical damage already......
