Cognitive behavioral therapy (CBT), which has recently been proposed as a first-line
approach for the treatment of insomnia, primarily includes cognitive strategies (addressing
dysfunctional beliefs regarding sleep and education related to sleep health) and behavioral
strategies (stimulus control [SC], sleep restriction [SR], relaxation) [9]. CBT approach for
insomnia (CBT-i) could improve poor sleep on several aspects (such as sleep latency, total
sleep time, etc.), as well as insomnia-related anxiety and depression [10]
