Normally, stress responses are beneficial for the body, provided they are moderate and cortisol returns to normal levels after the stressful situation ends. Chronic stress occurs when the body's stress levels remain too high for too long and do not return to normal levels for long enough. Chronic stress is associated with many chronic diseases, including asthma, back pain, arrhythmia, fatigue, headaches, high blood pressure, irritable bowel syndrome, ulcers, high blood sugar and diabetes.
Chronic stress takes a more significant toll on the body than does acute stress. It can raise blood pressure enough to cause hypertension, increase the risk of heart attack, stroke, and cardiac hypertrophy, increase vulnerability to anxiety and depression,
Therefore, prolonged stress included adverse psychological and physical health effects as well as the increased risk of premature death (Denollet, J., et al.
The stress not only causes physiological, but also psychological problems. How does our body react when the stress comes? That will be “hypothalamic-pituitary-adrenal”, which is called ATP , the system regulate the stress. When facing stressors, our mouth becomes dry, as it is conserving fluids because our HPA axis sensing danger. It’s used to escape predators or fighting with beasts. But this system isn’t designed for today’s diverse stressors because in modern world, most people need to worry about mortgages, relationships and promotions more than the fight for food. If we continur to let our body work under these stressful conditions, it will break down the strain. This process is called ”allostatic load”. HPA axis also produce serious and long-lasting negative effects, like physical and psychological in our
Stress means different things to different people and stress effects people in different ways. Some people think stress is something that happens to them such as an injury or a promotion and others think that stress is what happens to our mind, body and behaviors in response to an event. While stress does involve events and how one responds to them these are not the critical factors, but our thoughts about the situation in which we are involved are the critical factors. Essentially, stress exists whenever homeostasis is disturbed or cannot be maintained (Stress and the Social System Course Guide, 2013). Homeostasis refers to the body's ability to keep the internal chemical and physical environments constant. As your body begins to react to stress several changes occur. These changes include increased heart rate, blood pressure and secretion of stimulatory hormones. Ones body prepares itself in stressful situations to either stand ground and fight or to flee from the situation. Walter Cannon called this stressful reaction the fight-or-flight response (Greenberg, 2012).
Stress can affect anyone at anytime and anyplace. What’s important to know is that stress can actually be good for you. It is only when stress reaches unimaginable levels that it hinders your progress and makes you feel frustrated and sad. When confronted with a stressful situation the human body retreats to its survival mode, known as the “fight or flight response”. It causes the release of steroids and adrenaline from various glands in the body. These hormones send our respiratory, cardio-vascular, abdominal, endocrine and nervous systems into overdrive.
Getting sick is another negative factor of being overly stressed. Chronic stress compromises your immune system and stress hormones affect the body’s ability to fight off illness due to the fact that thymus’s ability to stimulate and coordinate the white blood cell activity.
Chronic stress exposes us to caustic hormones-constantly! The impact stress has on our body is measurable: it causes our brains to shrink, adds fat to our bellies, and even "unties" our chromosomes. Understanding the negative impact of stress is the first step in finding ways to deal with it. The next step, reduce stress.
Stress is “the body’s reaction to a change that requires a physical, mental, or emotional adjustment or response.” Many people realize that stress has a great impact on psychological health; however, they do not realize that physical health can be compromised as well. When the body is put under stress, physiological changes take place, such as increased heart rate or blood pressure. Many individuals do not know the extent to which stress can impact their bodies because they cannot see the changes taking place. If stress is prolonged, physical symptoms may begin to arise. These symptoms are real; however, they may or may not be due to some sort of physical disorder. Stress-induced anxiety may begin to form within the individual because of a constant fear that they have a serious medical condition. The cycle will repeat itself with potentially worsening symptoms.
Stress can be broadly defined as any stimulus that disrupts homeostasis, with the stress response referring to physiological and behavioral reactions to such a stimulus (Selye, 1950). It is the result of exposure to specific situation factors that are commonly referred to as stressors. The physiological response that results from short-term stress can is adaptive (fight or flight). Long-term stress, which occurs over a period of weeks to months, can have more delirious consequences including immunosupression, decreased reproduction, and diminish growth. (MacBeth et al. 2010) While perturbations can also a result of an aversive stimulus/situation, it can also be in response to rewarding events. Researchers tend to focus more intensely on perturbations
Stress is the combination of psychological, physiological, and behavioral reactions that people have in response to events that threaten or challenge them. Stress can be good or bad. Sometimes, stress is helpful, providing people with the extra energy or alertness they need. Stress could give a runner the edge he or she needs to persevere in a marathon, for example. This good kind of stress is called eustress. Unfortunately, stress is often not helpful and can even be harmful when not managed effectively. Stress could make a salesperson buckle under the pressure while trying to make a sales pitch at an important business meeting, for example. Moreover, stress can increase the risk of developing health problems, such as cardiovascular disease and anxiety disorders. This bad kind of stress is called distress, the kind of stress that people usually are referring to when they use the word stress.

Some take to other coping mechanisms that are not very great for the body. Some examples are stress eating, abuse of drugs and alcohol, bottling up the stress, and depression. These bad methods can cause serious damage to one’s health on the body.
