Anxiety-related Insomnia
Anxiety-related insomnia is the most common type of insomnia seen in clinical practice. Most cases of insomnia fall into this category, primarily caused by factors such as mental stress, anger, work or emotional pressure, and environmental changes.
Patients with anxiety disorders often complain of constant restlessness, inexplicable tension, inability to sit still, excessive rumination, and are accompanied by symptoms such as headache, insomnia, excessive sweating, palpitations, etc. This emotional state is difficult to dispel or clarify; the more one thinks about it, the more agitated one becomes. This indicates an anxiety neurosis, also known as anxiety disorder—a persistent emotional disturbance characterized by unease, tension, and fear. It may manifest as vague psychological tension and unpleasant anticipatory emotions without a specific focus, resulting in inexplicable feelings of tension and anxiety; alternatively, it may arise from repeated exposure to adverse events, overwhelming the mind and leading to a state of physical and mental exhaustion, gradually forming tension and anxiety; or it may stem from "forebodings" or imagined scenarios that trigger fear, causing constant worry, distress, and irritability about future events. The mental state may present as chronic doubt, anxiety, depression, a sense of impending doom, constant vigilance, trembling anxiety, and persistent nervousness. Patients often become distressed over minor issues, self-blame, always expect the worst, exaggerate illness, blame fate, lament endlessly, talk excessively, and easily lose temper or fidget restlessly.
Due to excessive anxiety, autonomic nervous system dysfunction often occurs, particularly hyperactivity of the sympathetic nervous system, resulting in physical symptoms such as excessive sweating in hands and feet, palpitations, rapid heartbeat, shortness of breath, muscle contractions, tremors, frequent urination, urgency, chest tightness, throat obstruction, bloating, diarrhea, excessive sweating, and numbness in limbs. Behaviorally, anxiety is also evident—common external manifestations include rubbing hands, sighing deeply, pulling out hair, and in severe cases, head-banging against walls or rolling on the floor. These physiological abnormalities result from heightened brain sensitivity and increased reactivity of the autonomic nervous system due to emotional stress.
Patients with anxiety disorders all experience varying degrees of sleep disturbances. In anxiety-related insomnia, difficulty falling asleep is the most prominent feature. After lying down, patients toss and turn without being able to fall asleep, their minds preoccupied with anxious thoughts they cannot resolve. As a result, they become increasingly excited, and the more excited they get, the less likely they are to sleep. Over time, patients develop a fear of sleep: every night they ponder, “Will I be unable to sleep tonight?” Constantly worrying about insomnia leads to actual inability to fall asleep. This vicious cycle results in anxiety-related insomnia, causing immense suffering and a strong desire to find a fundamental solution.
In addition to difficulty falling asleep, anxiety-related insomnia is notably characterized by shallow sleep—any slight noise can wake the patient, frequent dreams, a sensation of continuous dreaming throughout the night, and upon waking, patients often say, “I dreamed all night.” During the day, they feel listless, lack interest in everything, have no energy, and appear exhausted.
