What is Stress? - The American Institute of Stress
Stress is not a useful term for scientists because it is such a highly subjective phenomenon that it defies definition. And if you can’t define stress, how can you possibly measure it? The term “stress”, as it is currently used was coined by Hans Selye in 1936, who defined it as “the non-specific response of the body to any demand for change”. Selye had noted in numerous experiments that laboratory animals subjected to acute but different noxious physical and emotional stimuli (blaring light, deafening noise, extremes of heat or cold, perpetual frustration) all exhibited the same pathologic changes of stomach ulcerations, shrinkage of lymphoid tissue and enlargement of the adrenals. He later demonstrated that persistent stress could cause these animals to develop various diseases similar to those seen in humans, such as heart attacks, stroke, kidney disease and rheumatoid arthritis. At the time, it was believed that most diseases were caused by specific but different pathogens.

The Three Types of Stress Understanding stress can help you know more quickly when you need help. Stress is our built-in response to danger, a surge in hormones as we choose between fighting, fleeing, or freezing. The danger may be real or imagined, immediate or farther away; our bodies don’t know the difference. According to the American Psychological Association, the three types of stress — acute stress, episodic acute stress, and chronic stress — can all make us feel out of sorts or even ill, but chronic stress is often ignored. article continues after advertisement Acute Stress. definition of stress by Medical dictionary Definition Stress is defined as an organism's total response to environmental demands or pressures. When stress was first studied in the 1950s, the term was used to denote both the causes and the experienced effects of these pressures. More recently, however, the word stressor has been used for the stimulus that provokes a stress response. One recurrent disagreement among researchers concerns the definition of stress in humans. Is it primarily an external response that can be measured by changes in glandular secretions, skin reactions, and other physical functions, or is it an internal interpretation of, or reaction to, a stressor; or is it both?

3 Types of Stress and Health Hazards - Shawna Freshwater, PhD Stress is a feeling that people have when they are struggling to cope with challenges related to finances, work, relationships, environment, and other situations. Moreover, stress is felt when an individual perceives a real or imagined challenge or threat to a their well-being. People often use the word stress interchangeably with anxiety, feeling anxious, fearful, nervous, overwhelmed, panic, or stressed-out.

Teenage Stress Teens are under more stress today than ever before. Sound like an exaggeration? Despite the fact that I am often prone to hyperbole, consider this: being a teenager is not easy. Adolescence has always been a tricky developmental period defined by fundamental yet somewhat difficult changes (physical, cognitive, and social) experienced by teens as they make their way from childhood toward adulthood. These transitions trigger changes in the way the teen sees him/herself, and the way that others see and treat him or her. They are no longer children, but not yet adults, and this series of transitions not only has an impact on the individual experiencing the transitions, but also on parents, peers, and society as a whole.

The Effects of Stress on Your Body You’re sitting in traffic, late for an important meeting, watching the minutes tick away. Your hypothalamus, a tiny control tower in your brain, decides to send out the order: Send in the stress hormones! These stress hormones are the same ones that trigger your body’s “fight or flight” response. Your heart races, your breath quickens, and your muscles ready for action. This response was designed to protect your body in an emergency by preparing you to react quickly. 6 common causes of stress in children and teenagers - and tips on how to cope...
