Anxiety disorders can be divided into the following four levels i. Physical tension The person with anxiety disorders often feels that he cannot relax and his whole body is tense. His face is tense, his brow is furrowed, his expression is tense, and he sighs. II. Overreactivity of the autonomic nervous system The sympathetic and sympathetic nervous systems of anxiety patients are often overloaded. Patients have sweating, dizziness, shortness of breath, rapid heartbeat, body chills and fever, cold hands and feet or fever, difficult stomach, excessive urination and defecation, and obstructive feeling in the throat. Third, nameless worries about the future People with anxiety disorders always worry about the future. They worry about their loved ones, their property, and their health. People with anxiety disorders are like soldiers on sentry duty at all times and are alert to every slightest movement in their surroundings. Since they are always in a state of vigilance, it affects all their other work and even their sleep.
