Man, as a living being, develops in constant interaction with the environment. The environment is a source of opportunities to satisfy their needs and interests, but also of risks and threats. In essence, the individual's relationship with the environment consists in procuring and preserving the former, and in combating, avoiding, minimizing or counteracting the latter. Evolution has endowed the species with complex mechanisms aimed at preserving and optimizing adaptation to different environments and circumstances. Among them, the warning and defense systems have reached special relevance and development. The system that we call anxiety, fulfills these functions.
Living with a certain degree of anxiety, stress, is normal; it is an alert mechanism that our body has. But for at least 10% of the world's population, anxiety doesn't go away, and it can actually get worse over time. Fears, intense and persistent worries, terrors ... they can end up causing crises that manifest themselves with chest pains, shortness of breath, shortness of breath, palpitations, fear ...
The actions linked to anxiety as an alarm mechanism - note this voice: To the gun !! -, due to their adaptive and survival value, are hierarchically prioritized over other actions, so that they are withdrawn from the latter attentional, cognitive resources and behavioral in order to respond satisfactorily to the emergency. It is logical that, if, for example, a fire breaks out, the management of other ongoing action programs - reading, making a report, participating in a meeting, shopping - goes to the background. If the anxiety is punctual, the temporary stoppage of these programs, or their follow-up to a minimum, does not represent great inconveniences; But if the state of alarm is prolonged in time, it severely affects its development and, in the end, it would have such consequences for the individual that they would become new sources of anxiety.
Likewise, its appearance is related to non-psychiatric diseases that cause a great impact on the patient's day-to-day life, such as cardiovascular disease, gastrointestinal disorders, respiratory diseases, migraines and low back pain, among others.
