Today, psychophysiological insomnia is the most common persistent insomnia. The patient's inability to sleep occurs as a result of repetitive negative thoughts such as the thought that he will have difficulty sleeping before going to bed and/or past experiences involving the bedroom or the night. More effort to sleep causes more wakefulness and more difficulty falling asleep. Numerous studies have shown that insomnia seriously affects health and quality of life and can cause various problems including memory problems, depression, irritability, cardiovascular and cerebrovascular diseases, etc. Therefore, looking for effective ways to improve sleep quality is important for individual and social health. Today, drug therapy, psychotherapy, physiotherapy and cognitive-behavioral therapy are widely used treatments for insomnia.
