In order to fully understand the meaning of the term restlessness, the first thing to do is establish its etymological origin. Thus, it should be stressed that it emanates from Latin, specifically from the word "restless," which is made up of three distinct parts:
• The prefix “in-”, which is equivalent to “without”.
• The verb “quiescere”, which can be translated as “repose”.
• The suffix "-tud", which comes to refer to a quality.

Restlessness is the lack of stillness . The term is used to name the shock , the uproar, restlessness or unease. For example: "The words of the president of the company generated concern among workers", "Knowing that the murderer is still free gives me great concern", “The restlessness of the animals before each storm is evident”.
The restlessness can be understood as a state from nervousness that occurs before a certain situation. The person who is restless does not have inner peace nor can she relax, since there is something that causes her concern. In this way, when a worker is informed that he has to go talk to his boss, he may feel anxious about the situation since his superior may inform him that he will be sanctioned or fired. Until you talk to your boss, then, the employee will feel restless.
The restlessness can also be analyzed as a symptom of anxiety . Being restless, the person cannot concentrate on what they are doing because their attention and thoughts are focused on another issue. This causes the restlessness to cause everyday problems.
Moreover, within the field of medicine there is talk of concern as a synonym for agitation. This is a state of extreme excitement, nervousness or emotion that a person experiences under different circumstances. From that state, it is worth knowing the following hallmarks:
• It can go “forming” in time or it can appear suddenly.
• Its durability is not exact, since in some people it will only be a matter of minutes and in others it can last up to months.
• Among the main causes of agitation or restlessness are an allergic reaction, a picture of alcohol intoxication, heart problems, infections, trauma, lack of vitamin B6, nicotine or alcohol withdrawal, depression, schizophrenia, anxiety ...
• Whenever it is very intense or frequent, it is advisable to go to the doctor so that he / she decides not only the reasons for its appearance but also the most appropriate treatment to alleviate it.
• To get the affected person to leave that concern behind, in addition to the recommendations of the health worker, it is necessary that you sleep well and enough as well as being in a relaxed environment.
Restlessness, on the other hand, may be the inclination of the cheer up to something: "Juan Manuel always had artistic concerns", "My literary concern led me to study the work of the main Chilean poets of the twentieth century", "It bothers me people who have no concerns and who is satisfied with fulfilling their daily obligations and nothing else".
