CBT in bed is not a commonly used term. However, Cognitive Behavioral Therapy for Insomnia (CBT-I) is a short, structured, and evidence-based approach to treating insomnia. CBT-I is a multi-component treatment that incorporates different approaches to address underlying psychological, behavioral, and physiological processes and factors that underpin and perpetuate insomnia. The cognitive part of CBT teaches you to look for and change beliefs that affect your ability to sleep, while the behavioral part of CBT helps you develop good sleep habits and avoid behaviors that can make it hard to fall asleep or stay asleep. CBT-I can reduce the time it takes to fall asleep and the number of awakenings during sleep, resulting in an individual increasing their total sleep time.
