The best sleep therapy often depends on the person's specific sleep disorder and its underlying causes, but cognitive behavioral therapy for insomnia (CBT-I) is widely regarded as one of the most effective approaches. Effective CBT-I focuses on identifying and changing the thoughts and behaviors that contribute to sleep difficulties. This therapy typically includes techniques such as sleep restriction, stimulus control, relaxation training, and cognitive restructuring to address negative beliefs about sleep. Numerous studies have shown that CBT-I can lead to significant improvements in sleep quality and duration without the side effects associated with medication. For some people, a combination of CBT-I with other treatments, such as medication or lifestyle changes, can provide the best results for achieving restful sleep.
