Anxiety is a normal response to a threat or to psychologic stress. Normal anxiety has its root in fear and serves an important survival function. When someone is faced with a dangerous situation, anxiety triggers the fight-or-flight response.
This combination of reactions to stress is also known as the "fight-or-flight" response because it evolved as a survival mechanism, enabling people and other mammals to react quickly to life-threatening situations.
Anxiety refers to anticipation of a future concern and is more associated with muscle tension and avoidance behavior. Fear is an emotional response to an immediate threat and is more associated with a fight or flight reaction – either staying to fight or leaving to escape danger.
As already mentioned, the two main behaviours associated with fear and anxiety are to either fight or flee. Therefore, the overwhelming urges associated with this response are those of aggression and a desire to escape, wherever you are.
Fortunately, anxiety is highly treatable. Self-help strategies to overcome anxiety can be helpful, but it is also important to talk to your doctor about your treatment options. By taking steps to get better, you can help ensure that your anxiety isn't keeping you from achieving the things you want to do.
Anxiety disorders are severe conditions stemming from excessive worrying and rumination. People with anxiety as a mental illness have feelings of anxiety that do not go away and can interfere with daily activities such as job performance and relationships, according to the National Institute of Mental Health.
Anxiety is what we feel when we are worried, tense or afraid – particularly about things that are about to happen, or which we think could happen in the future. Anxiety is a natural human response when we feel that we are under threat. It can be experienced through our thoughts, feelings and physical sensations.
People under stress experience mental and physical symptoms, such as irritability, anger, fatigue, muscle pain, digestive troubles, and difficulty sleeping. Anxiety, on the other hand, is defined by persistent, excessive worries that don't go away even in the absence of a stressor.
Changes in The Amygdala and Hippocampus
It is responsible for responses to fearful and threatening stimuli. With persistent anxiety, the amygdala increases in size, amplifying the body's response to scary situations. The hippocampus plays a major role in learning and memory.
Initial reactions to trauma can include exhaustion, confusion, sadness, anxiety, agitation, numbness, dissociation, confusion, physical arousal, and blunted affect. Most responses are normal in that they affect most survivors and are socially acceptable, psychologically effective, and self-limited.
In addition, it's been found that persistent anxiety can cause the amygdala to grow, intensifying the body's response to threatening or scary situations. Conversely, anxiety can cause the hippocampus to shrink. The hippocampus is an area of the brain that plays a major role in learning and memory.
In summary, anxiety evolved to keep us out of danger, to obey the rules of our group, and to treat each other with respect.
Difficult experiences in childhood, adolescence or adulthood are a common trigger for anxiety problems. Going through stress and trauma when you're very young is likely to have a particularly big impact. Experiences which can trigger anxiety problems include things like: physical or emotional abuse.
In fact, if you're under chronic stress, then your body may be in a perpetual state of fight or flight, and that's not good for your health. Here are some of the ways you can tell if you're constantly in this mode and how your chiropractor can help you get out of it.
Further, many labs have shown that behavioral strategies such as relaxation, deep breathing and meditation can reduce the stress response. And what about that sense of control? Perhaps by learning about how the brain reacts to stress, you may come away with an enhanced sense of control.
As noted above, these changes are believed to be triggered by the sympathetic nervous system through the release of stress hormones into the bloodstream. 3 This release causes immediate physical reactions in preparation of the muscular activity needed to fight or flee the threat.
But researchers don't know exactly what causes anxiety disorders. They suspect a combination of factors plays a role: Chemical imbalance: Severe or long-lasting stress can change the chemical balance that controls your mood. Experiencing a lot of stress over a long period can lead to an anxiety disorder.
A certain degree of anxiety can help people anticipate obstacles, remain cautious and stay organized, said Ellen Hendriksen, a clinical psychologist in Boston and the author of “How to Be Yourself: Quiet Your Inner Critic and Rise Above Social Anxiety.”
It is both psychological and physical. The brain's amygdala makes the determination of threat and signals the hypothalamus, a central command center, which broadcasts the signal through the autonomic nervous system and sets off a cascade of hormones, including adrenaline.
Once the body recovers from chronic stress, and as we live a much less anxious lifestyle, normal health naturally follows. Managing stress well and containing anxious behavior leads to a normal life. There is no need to worry about not achieving complete recovery since it naturally follows when we do the right work.
Borderline personality disorder is one of the most painful mental illnesses since individuals struggling with this disorder are constantly trying to cope with volatile and overwhelming emotions.
