This study focuses on individuals with chronic insomnia combined with excessive arousal/anxiety, with the main objective of investigating the effectiveness of Tai Chi in treating CI with excessive arousal/anxiety.

Patients with chronic insomnia often experience both daytime fatigue and difficulty falling asleep at night, as well as shallow sleep and easy awakening, which is a manifestation of 24-hour excessive wakefulness. Additionally, insomnia is often associated with anxiety and tension. Therefore, for patients with chronic insomnia accompanied by anxiety, relieving anxiety is often an important means of treating insomnia. In recent years, an increasing number of studies have shown that Tai Chi has potential therapeutic value in treating mental disorders such as insomnia and anxiety. Tai Chi is a coordinated and unified physical and mental exercise that regulates the body's functional state through rhythmic and regular physical activities, and is combined with psychological "relaxation" activities. Therefore, the investigators propose the hypothesis that Tai Chi training may improve chronic insomnia with excessive arousal/anxiety through intermediate pathways such as neuroendocrine, immune function, neurochemistry, etc. This study aims to explore the effects of Tai Chi on chronic insomnia combined with excessive arousal/anxiety, broaden new ideas for non pharmacological treatment of sleep problems, and provide data reference for the development of more precise sleep aid exercise plans in the future.
