Anxiety
Anxiety is a psychological and physiological phase characterized by cognitive, physical, emotional and behavioral problems. These elements create a discomfort that is typically associated with anxiety, fear, fear or worry. Anxiety is a general mood, which can often occur without an identifiable stimulus start. As such, it has been separated from fear, which is observed in the presence of a threat. Moreover, the fear associated with specific behaviors of escape and avoidance, whereas anxiety is due to the threats perceived as uncontrollable or inevitable.
Another view is that anxiety is a future state of mind in which we are ready or willing to try to cope with future adverse events suggest that there is a distinction between future vs. present dangers divides the anxiety and fear. Anxiety is considered a normal reaction to stress. It can help a person to manage a difficult situation, eg at work or school, asking someone to do it. When anxiety becomes excessive, it may fall under the classification of an anxiety disorder.
The physical effects of anxiety can include palpitations, weakness and muscle tension, fatigue, nausea, pain in the chest, shortness of breath, upset stomach or headaches. The body prepares to deal with a threat: blood pressure and heart rate are increased, sweating is increased blood flow to large muscle groups increased, and immune and digestive functions inhibited (the fight or flight ). The outward signs of anxiety may include pale skin, sweating, trembling, and pupillary dilation. Anyone have anxiety can also be seen as a feeling of fear or panic. Although panic attacks are not experienced by all who have anxiety, they are a common symptom. Panic attacks usually come without warning, and although the fear is generally irrational, the perception of danger is very real. A person who has a panic attack often feel as if he or she is about to die or vanish.
Anxiety is not only physical, there are many emotional beings. Include feelings of fear or fear, trouble concentrating, feeling tense or nervous, anticipating the worst, irritability, restlessness, watching (and waiting) for the signs (and events) or danger, and feeling that his mind has gone blank and nightmares / dreams, obsessions, feelings of déjà vu, a feeling trapped in her mind, and the feeling that all is fear. The cognitive effects of anxiety may include reflections on hazards, such as fear of dying. You can ... the fear that the chest pain [physical symptoms of anxiety] are a heart attack or shooting pains in the head [other physical symptoms of anxiety] are the result of a tumor or aneurysm. It feels intense fear when thinking about dying, or you can think more often than usual or can not get out of his mind.
The psychologist of Boston University conducted a research study that found three common characteristics of people with chronic anxiety, which he described as a generalized biological vulnerability, psychological vulnerability widespread and a specific psychological vulnerability. Although questions chemicals in the brain that lead to anxiety
(especially as a result of genetics) are well documented, this study highlights an additional environmental factor that might result from being raised by parents who suffer from chronic anxiety themselves.
Neural circuitry in which the amygdala and the hippocampus is believed that the underlying anxiety. When people are confronted with unpleasant and potentially harmful stimuli, such as bad smells or tastes, PET show increased blood flow in amygdala.In these studies, the participants also reported moderate anxiety. This may indicate that anxiety is a protective mechanism to prevent the auditor to carry out malicious behavior.
