This component focuses on identifying and challenging negative thoughts and beliefs about sleep that may be contributing to insomnia. Individuals are encouraged to keep a sleep diary to track their sleep patterns and identify patterns of negative thinking that may be interfering with their ability to sleep. By challenging these thoughts and replacing them with more realistic and positive beliefs, individuals can reduce anxiety about sleep and improve their overall sleep quality. Relaxation techniques are also commonly used in CBT-I to help individuals reduce stress and anxiety before bedtime.
