What is stress

  1. 1. What is stress? The Body’s Stress Response When you perceive a threat, your nervous system responds by releasing a flood of stress hormones, including adrenaline and cortisol. These hormones 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 – preparing you to either fight or flee from the danger at hand. Stress is a normal physical response to events that make you feel threatened or upset your balance in some way. When you sense danger – whether it’s real or imagined – the body's defenses kick into high gear in a rapid, automatic process known as the “fight-or-flight” reaction, or the stress response. The stress response is the body’s way of protecting you. When working properly, it helps you stay focused, energetic, and alert. In emergency situations, stress can save your life – giving you extra strength to defend yourself, for example, or spurring you to slam on the brakes to avoid an accident. The stress response also helps you rise to meet challenges. Stress is what keeps you on your toes during a presentation at work, sharpens your concentration when you’re attempting the game-winning free throw, or drives you to study for an exam when you'd rather be watching TV. But beyond a certain point, stress stops being helpful and starts causing major damage to your health, your mood, your productivity, your relationships, and your quality of life. How do you respond to stress? It’s important to learn how to recognize when your stress levels are out of control. The most dangerous thing about stress is how easily it can creep up on you. You get used to it. It starts to feels familiar even normal. You don’t notice how much it’s affecting you, even as it takes a heavy toll. The signs and symptoms of stress overload can be almost anything. Stress affects the mind, body, and behavior in many ways, and everyone experiences stress differently. Stress doesn’t always look stressful Psychologist Connie Lillas uses a driving analogy to describe the three most common ways people respond when they’re overwhelmed by stress:  Foot on the gas – An angry or agitated stress response. You’re heated, keyed up, overly emotional, and unable to sit still.  Foot on the brake – A withdrawn or depressed stress response. You shut down, space out, and show very little energy or emotion.  Foot on both – A tense and frozen stress response. You “freeze” under pressure and can’t do anything. You look paralyzed, but under the surface you’re extremely agitated. Causes of stress The situations and pressures that cause stress are known as stressors. We usually think of stressors as being negative, such as an exhausting work schedule or a rocky relationship. However, anything that puts high demands on you or forces you to adjust can be stressful. This includes positive events such as getting married, buying a house, going to college, or receiving a promotion. What causes stress depends, at least in part, on your perception of it. Something that's stressful to you may not faze someone else; they may even enjoy it. For example, your morning commute may make you anxious and tense because you worry that traffic will make you late. Others, however, may find the trip relaxing because they allow more than enough time and enjoy listening to music while they drive. Common external causes of stress Not all stress is caused by external factors. Stress can also be self-generated:  Major life changes  Work  Relationship difficulties  Financial problems  Being too busy  Children and family Common internal causes of stress
  2. 2. Not all stress is caused by external factors. Stress can also be self-generated:  Inability to accept uncertainty  Pessimism  Negative self-talk  Unrealistic expectations  Perfectionism  Lack of assertiveness Effects of chronic stress The body doesn’t distinguish between physical and psychological threats. When you’re stressed over a busy schedule, an argument with a friend, a traffic jam, or a mountain of bills, your body reacts just as strongly as if you were facing a life-or-death situation. If you have a lot of responsibilities and worries, your emergency stress response may be “on” most of the time. The more your body’s stress system is activated, the easier it is to trip and the harder it is to shut off. Long-term exposure to stress can lead to serious health problems. Chronic stress disrupts nearly every system in your body. It can raise blood pressure, suppress the immune system, increase the risk of heart attack and stroke, contribute to infertility, and speed up the aging process. Long-term stress can even rewire the brain, leaving you more vulnerable to anxiety and depression. Many health problems are caused or exacerbated by stress, including:  Pain of any kind  Heart disease  Digestive problems  Sleep problems  Depression  Obesity  Autoimmune diseases  Skin conditions, such as eczema The Three Stages of Stress An endocrinologist named Dr. Hans Selye outlined a three stage model of the body’s response to stress. He called his model the General Adaptation Syndrome. Understanding these three stages will give you a better idea as to the symptoms that occur with stress and how to manage them. General Adaptation Syndrome: 1. Alarm 2. Resistance or Adaptation 3. Exhaustion The Alarm Stage: This is also known as the “fight or flight” reaction. It may occur as a response to imminent danger or to hearing stressful news. In this stage, your body physically reacts to stress by releasing adrenaline and another hormone called corticotropin to increase your heat and breathing rates and help you move more quickly in a dangerous situation. Other physical responses to stress during this stage include “butterflies” in your stomach, an elevation in blood pressure, dilation in the eyes, dry mouth, tensing of muscles, and difficulty concentrating. The Resistance or Adaptation Stage: During this stage, your body is still on alert for imminent danger. If this stage of stress becomes prolonged, such as when dealing with a long-term stressful situation, your body will eventually grow taxed by the physical responses. Over time, your immune system may be compromised, leaving you even more susceptible to illness. It only takes a few days in the resistance and adaptation stage for the immune system to fall into a weakened state. The Exhaustion Stage: The final stage in the General Adaptation Syndrome is the exhaustion stage, in which your body returns itself back to normal. Additional hormones, called cortisols, are released to help relieve the damaging effects of stress. They are continually secreted until your body’s chemistry comes back into balance. These hormones, while able to offer the body some short-term relief, ultimately suppress the immune system and have the potential to worsen biological and psychological diseases and disorders. Stress and Personality We all have certain features to our personality that make us unique as people; however there are many aspects of our personality that are similar to other people. These similar personality factors are called Personality Traits. Research has indicated that certain personality traits can make us more vulnerable to stress. People with such traits are known as Type A personalities. Type A's tend to be more competitive, more impatient, have time urgency when compared to the more relaxed and laid back Type B personalities. It's important to realise that we are all a mixture of type A and B personality traits but if we are excessively type A this can make us more

We can reduce our Type A personality traits through the techniques taught on this course. Here are some Type A and some Type B Personality Traits: Type A Personality Traits Type B Personality Traits · Must get things finished · Do not mind leaving things unfinished for a while · Never late for appointments · Calm and unhurried about appointments · Excessively competitive · Not excessively competitive · Can't listen to conversations, interrupt, finish others sentences · Can listen and let the other person finish speaking · Always in a hurry · Never in a hurry even when busy · Do not like to wait · Can wait calmly · Very busy at full speed · Easy going · Trying to do more than one thing at a time · Can take one thing at a time · Want everything to be perfect · Do not mind things not quite perfect · Pressurised speech · Slow and deliberate speech · Do everything fast · Do things slowly · Hold feelings in · Can express feelings · Not satisfied with work/life · Quite satisfied with work/life · Few social activities/interests · Many social activities/interests · If in employment, will often take work home · If in employment, will limit working to work hours
