Anxiety can be defined as an emotion characterized by a very unpleasant state of inner restlessness. This is also accompanied by very anxious behavior that includes pacing, rumination, and somatic complaints. It is a subjectively very unpleasant feeling and includes the fear of various types of unpleasant events in the future, such as the death of a family member or a failed examination. However, it is not the same as fear, apprehension, and restlessness that form part of anxiety when a person feels completely uneasy and acquires a regular amount of tension. It can also be accompanied by muscle tension, fatigue, restlessness and various kinds of problems related to concentration. When you experience this type of restlessness on a regular basis, it can result in a type of disorder called an anxiety disorder.

People who suffer from anxiety may face situations where they have to withdraw from the situation. It can also be a short-term anxiety state or a long-term trait. Trait anxiety can be categorized as a condition in which a person is worried about their long-term events. So this is very close and resembles the concept of neuroticism. It is a group of mental disorders characterized by different types of feelings of fear and anxiety. These disorders are generic and can also occur as a result of drug use, including alcohol and caffeine. There are other mental disorders such as bipolar disorder, major depressive disorder, and eating disorders that can contribute significantly to anxiety.

There are various important causes of anxiety disorders. These include early life experiences, biological vulnerability, social issues related to gender, evolutionary psychology, and evolutionary biology that includes genes and medicine. Although individual genes have very little influence on complex traits and can interact very strongly both with each other and with various external factors, research is currently underway to uncover all possible molecular mechanisms. Anxiety can also be a symptom of various underlying health problems, such as COPD, which is chronic obstructive pulmonary disease, heart failure, and hearing arrhythmias.

Gender socialization also contributes a lot to anxiety. Women have higher levels of anxiety than men. Many people face many short-term levels of social anxiety. When these problems are prolonged, they become long-term social anxiety disorders, and then it is very difficult to avoid these disorders
