three types of stress?
82429
Compressive stress (or compression) is the stress state when the material tends to compact (volume decrease). A simple case of compression is the uniaxial compression induced by the action of opposite, pushing forces. Most materials can carry compressive stress, even the granules such as sands.\n\nTensile stress is a loading that tends to produce stretching on a material by the application of axially directed pulling forces. Materials can withstand some tensile loading, but if enough force is applied, they will eventually break into two parts. Steel is an example of a material with high tensile strength.\n\nShear stress is caused when a force is applied to produce a sliding failure of a material along a plane that is parallel to the direction of the applied force e.g. when cutting paper with scissors.

There are many different ways to decrease stress in your life.  However, there are also different types of stress.  For example if your stress is from trauma or some other sort of seriously stressful experience, then my suggestions will not be sufficient and your stress may require some short-term therapy (often known as PTST - Post Traumatic Stress Disorder).  If your stress is the normal everyday stress that we all put up with (job stress, kids, responsibilities, financial, muscle tension, traffic, etc.) then I offer the following suggestions.\n\nMany men prefer to destress through activities such as playing group sports, hanging out with their pals or working out at a gym. Women can also find ways of relaxing by participating in activities or hobbies they enjoy.  Additionally, practicing relaxation to relieve muscle tension is extremely effective and can be practiced quickly and easily if sufficiently learned. Practice by tensing your fists for 5 seconds, then release the tension completely. Say to yourself, "relax". Notice that your hand is now MORE relaxed than before the tension. Practice this method moving all throughout the body.  This is called Progressive Muscle Relaxation and I'm sure you can find a full script somewhere on the web. Other forms of relaxation may include yoga or other exercise, meditation, visualization, prayer or other spiritual practice or communion, talking to a friend or loved one, seeking profession help through therapy or medication, and so on.  If you find that your stress is a little more permanent that just every day experiences, then you may consider relocating to a city with a slower pace or changing to a job that will be less stressful.  Examine your life and see where your stress is coming from and then slowly you can find creative ways of eliminating or decreasing the stress as a whole. Good Luck and don't forget the powerful connection of Mind and Body!!

Summary of The Ways or Means by which Stress is Developed \nIf psychologists completely understood how stress and fears developed, we would know how to produce and reduce a phobia or an anxiety state. We don't. There seems to be a wide variety of life experiences which result in some form of stress, fear, anxiety, or psychosomatic illness. It would be convenient if life were simpler but it isn't. Perhaps a summary will help you review the ways you might become stressed and anxious \n\nEnvironmental factors and processes \n\nChanges, such as sudden trauma, several big crises, or many small daily hassles, cause stress. Intense stress years earlier, especially in childhood, can predispose us to over-react to current stress. \nEvents, such as barriers and conflicts that prevent the changes and goals we want, create stress. Having little control over our lives, e.g. being "on the assembly line" instead of the boss, contrary to popular belief, often increases stress and illness. \nMany environmental factors, including excessive or impossible demands, noise, boring or lonely work, stupid rules, unpleasant people, etc., cause stress. \nConflicts in our interpersonal relationships cause stress directly and can eventually cause anxieties and emotional disorders. \nConstitutional or physiological processes \n\nThe human body has different ways of responding to stress; one quick responding nerve-hormonal system involving adrenaline, another long-lasting system involving cortisol, and perhaps others. These systems not only determine the intensity of our anxiety reactions but also our attitudes, energy level, depression, and physical health after the stressful events are over. As individuals, our nervous systems differ; however, according to Richard Dienstbier at the University of Nebraska, we may be able to modify our unique physiological reactions by learning coping skills. \nThe genetic, constitutional, and intrauterine factors influence stress. Some of us may have been born "nervous" and "grouches." Almost certainly we are by nature prone to be shy or outgoing, and we inherit a propensity for certain serious psychological disorders. We don't know yet if different treatments are required for genetically determined problems than for learned problems. \nLearning processes \n\nHaving a "bad experience" causes us to later be stressed in that situation, i.e. pairing a neutral stimulus (situation) with a painful, scary experience will condition a fear response to the previously neutral stimulus. (classical conditioning) \nFears and other weaknesses may yield payoffs; the payoffs (like attention or dependency) cause the fear to grow. (operant conditioning) \nAvoiding frightening situations may reinforce and build fears and stress. (operant conditioning--negative reinforcement) \nCognitive learning processes \n\nSeeing others afraid and being warned of real or nonexistent dangers can make us afraid under certain conditions. (modeling) This can include seeing a movie or TV or reading a book or perhaps just fantasizing a danger. \nSome people have learned to see things negatively; they have a mental set that causes them to see threats and personal failure when others do not. Of course, seeing the situation as negative ("terrible"), unpredictable, uncontrollable, or ambiguous is stressful. \nMany long-lasting personality factors (neuroticism, pessimism, distrust, lack of flexibility and confidence) are related to stress, decision-making, and physiological responses. \nHaving a negative self-concept--expecting to be nervous and a loser--generates stress. \nIrrational ideas about how things "should be" or "must be" can cause stress when we perceive that life is not unfolding as we think it should. \nBelieving that we are helpless, that we can't handle the situation causes stress. \nDrawing faulty conclusions from our observations, such as scary ideas, like "the

Hey I know just how you feel. I am type A personality so i get stressed real bad real fast. I try and find a quite place that i can sit cross legged and place my hands on my knees, I then take deep breaths in thru the nose to the count of ten, hold it for 7, then release it thru my mouth to the count of 10 with my tounge pressed against the roof of my mouth. This helps clear the mind becuase you are concentrating on breathing. All it really is is meditation. Try it and see if it helps.

Stress\nEveryday we are confronted with problems. When we are confronted with a problem we must determine the seriousness of the problem and determine whether or not we have the resources (e.g., emotional resources) necessary in order to cope with problem. If we believe that the problem is serious and we also believe that we do not have the resources necessary to cope with the problem, we will perceive ourselves as being under stress (Cohen et. al., 1995). Stress can be defined as a process in which environmental demands strain an organisms adaptive capacity, resulting in both psychological as well as biological changes that could place a person at risk for illness (Cohen et. al., 1995). Things that cause us stress are called stressors (Rubin, Paplau, & Salovey, 1993). Many events can be thought of as stressors. These include disasters, life crises, life changes, and daily hassles (Rubin, Paplau, & Salovey, 1993). Examples of stressors include: hurricanes, earthquakes, disease, divorce, unemployment, marriage, and traffic jams. Stressors are things that interfere with an important personal goal (Rubin, Paplau & Salovey, 1993). The more important the goal is, the more stress a person will feel when that goal is threatened (Rubin, Paplau & Salovey, 1993). So for example, if it's important to a person to get to class on time, the person will feel stress if he gets caught in traffic. The goal is to get to class on time and the stressor is the traffic jam. The more important it is for the person to be on time, the more stressful the traffic jam will be. So, a person is likely to feel more stress on the day when an exam is given and there is a traffic jam, than he will feel when no exam is given and there is a traffic jam. \nThree Theories of Stress. Stress affects everyone, young and old, rich and poor. Life is full of stress. There is work stress, school stress, financial stress, and emotional stress, to name a few. There are three theories or perspectives regarding stress. There is the environmental stress perspective, the psychological stress perspective, and the biological stress perspective. The environmental stress perspective emphasizes assessment of environmental situations or experiences that are objectively related to substantial adaptive demands (Cohen et. al., 1995). The psychological stress perspective emphasizes people's subjective evaluations of their ability to cope with the demands presented to them by certain situations and experiences (Cohen et. al., 1995). Finally, the biological stress perspective emphasizes the activation of certain physiological systems in the body that have been shown time and time again to be regulated by both psychologically and physically demanding conditions (Cohen et. al., 1995). \n\nStress and Biology. Stress is not necessarily a bad thing. A certain amount of stress is natural. None of us live stress free lives. However, while a certain amount of stress is normal, chronic negative stress may be harmful to our health. Thomas Holmes asserted that any and all change is stressful because it forces individuals to adapt to new, unfamiliar circumstances (Brehm & Kassin, 1993). Holmes acknowledged that some changes require more of an adjustment than other changes (Brehm & Kassin, 1993). Holmes believes that the change resulting from both positive (e.g., marriage, promotion, graduation) and negative (e.g., divorce, unemployment) life events are stressful and may possibly do harm to an individual's health (Brehm & Kassin, 1993). When an individual is faced with stress, his body mobilizes for action in what is called a fight or flight reaction (Rubin, Paplau, & Salovey, 1993). During a fight or flight reaction, the heart rate increases, breathing is accelerated, and the muscles tense up as if in preparation to throw something like a rock (fight) or to run away (flight) (Rubin, Paplau, & Salovey, 1993). For example, when approached by a thief, you can either fight him or you can try t

Sharon you have asked a very complex question related to stress.  My reason is that you could be suffering from "Post-traumantic Stress Disorder.  Or you could just have :Generalized Anxiety Disorder.    \n\nSince you are not my patient it really is not possible to spend two or three hours with you to ask questions that I have designed to get at the root cause of your stress, known or unknown.  \n\nI don't believe in drugs for stress, anxiety or mild depression.  \n\nDrugs only mask the root cause an it is important to me to find out what the root cause of your problem is and work together with you to offer you alternative situations that you must pick to resolve your problem.   (I never tell a person what they must do.  I just give them the alternatives an let them pick.  Ofcourse I will tell you what is the light at  the end of the tunnell with your choice).\n\nHere are ways that cause stress.\n\n1. recurrent and intrusive distressing recollections of the event.  repetitive play in which themes or aspects of the trauma are expresed.\n\n2. recurrent distressing dreams of the event\n\n3. sudden acting or feeling as if the traumatic event where recurring.\n\n4. intense psychological distress at exposure to events that symbolize or resemble an aspect of the traumatic event, includig  anniversaries of the trauma.\n\n5. efforts to avoid thoughs or feeling associated with the trauma\n\n6. eforts to avoid the activities of situations that arouse recollections of the trauma\n\n7. inability to recall an important aspect of the trauma.\n\n8. markedly diminished interest in sifnificatn activities.\n\n9. feeling of detachment or estrangement from others.\n\n10. restricted range of affects, unable to have loving feelings\n\n11. sense of  foreshortened future.  Does not expect to have a career, marriage or children, or a long life.\n\n12. difficulty falling or staying asleep\n\n13. irritability or outbursts of anger\n\n14. difficulty concentrating\n\n15. hypervilgilance\n\n16. exaggerted startle response\n\nIf you have atleast 6 of the 18  symptoms below, you have whatn is known as generalized anxiety disorder.\n\nmotor tension\n\n1. trembling, twitching, or feeling shaky\n2. muscle tensions, aches, or soreness\n3. restlessness\n4. easy fatigabilitys\n\n\nAutonomic hyperactivity\n\n5. shortness of breath or somothering sensations\n6. palpitations or accelerated heart rate (Tachycardia).\n7. sweating, or cold clammy hands\n8.  dry mouth\n9. dizziness or lightheadedness\n10. nausea, diarrhea, or other abdominal distress\n11. flushes (Hot flashes) or chills\n12. fequent urination\n13. trouble swallowing or "lump in throat"\n\nVigilance and scannig\n\n14. feeling keyed up or on edge\n15. exaggerated startle response\n16. difficulty concentrating or "mind goes blank" becasue of anxiety\n17. trouble falling or staying asleep\n18, irritability\n\nIf none of the above apply to you then the pimples are not related to any stress in your life. \n\nI been a volunteer medical doctor working in refugee camps located in war zones since 1971.  Have no known living relatives or parents since 1955.  So I can relate to what it is like to sometimes feel alone.  This is not the cause for stress, like you I keep my mind diverted on other things. \n\nNo stress if the above does not apply to you.  So you don't have to cope with stress related situations.    \n\nAgain if none of the above relate to you, then you should see a dermatologist to have him/her to take a good look at your skin.  \n\nThe air is so dirty in most countries, this could be the casue of the change in your clear skin.  As you don't stay where you came from before you went to the UK.   \n\nWish you all the best.  Hope the problem is resolved.   \n\nClinical Psychiatrist, France.   \n\n\n\n1

Stress is tension or pressures that are a natural part of living our lives.  Changes and events in our lives (getting married, illness, changing jobs) are a major source of stress.  Pressures and tension from both good and bad changes can trigger our Stress Alarm System making us feel that we want to either fight the stress or run away from it.  \n\nPreventing Stress:\nEating Right Helps:  Foods high in preotein, Vitamin C, B vitamins and Vitamin A protect us from the effects of stress.  These are found in whole grain products, fruits and veggies, expecially citrus fruits, dark green veggies, meat and dairy products.  Caffeine, refined sugars, starches and junk food create false energy and stress the body even more.\nManage Time Better:  Take five minutes at the beginning of each day and make a "things to do" list.  Converty this list into a priority list of primary tasks, secondary tasks and miscellaneous tasks.  Do Primary tasks first and continue until the list is completed.  Don't over schedule - leave time for unexpected events.  Reward yourself for a job well done.\nExercise your tension away:  You feel healthier and less stressed when you develop an exercise plan that meets your life style, needs and ability.  Yoga and stretching exercises are good for developing flexibility and relaxation.  \nIn a nut shell:  everyone will get stressed.. but how to manage your stress and keep it from occuring as often just takes a few little changes throughout your day to make it much easier to get through the bad parts!
