Stimulus control therapy A series of methods to reinforce the bed/bedroom association with sleep and to re-establish a regular sleep-wake schedule: (1) going to bed only when you want to sleep; (2) getting up when you cannot fall asleep; (3) using the bed/bedroom only for sleep (no reading in bed, watching TV, etc.); (4) getting up every morning on time; (5) no naps. Sleep Restriction Therapy A method of strictly limiting bedtime to as close as possible to actual sleep time, thus resulting in mild sleep deprivation. The duration of bed rest is gradually increased over a period of time (days/weeks), eventually reaching the desired sleep duration. Relaxation training A clinical approach aimed at reducing somatic tension (e.g. progressive muscle relaxation, self-control training) or intrusive thoughts that interfere with sleep (e.g. imagery training, meditation). Most relaxation training begins with professional guidance and is trained daily for several weeks. Cognitive therapy This psychotherapy approach aims to reduce worries and change misconceptions and perceptions about sleep, insomnia and insomnia outcomes . Other cognitive strategies are also used to control intrusive thinking while in bed and to reduce excessive concern about the consequences of daytime insomnia. Sleep hygiene education Common guidelines regarding health and environmental factors (e.g., diet, exercise, substance use, light, noise, and temperature) that can promote or interfere with sleep. This also includes information about normal sleep and changes in sleep as age increases. Cognitive Behavioral Therapy (CBT) An integrated treatment approach that includes behavioral (e.g., stimulus control, sleep restriction, and relaxation therapy) and cognitive strategies.
