Effects of Cognitive Correction and Stimulus Control in Chronic Insomnia Patients

Cognitive correction: a) correcting unrealistic sleep expectations; b) maintaining a natural sleep onset; c) avoiding worry about losing control oversleep; d) not associating nocturnal dreaming with adverse daytime consequences; e) avoiding feelings of frustration due to one night of poor sleep; f) developing tolerance to the impact of insomnia and avoiding compensatory behaviors. Stimulus control: 1. Minimize wakefulness during time in bed and establish a positive association between sleepiness and the bed. 2. Use the bed only for sleep and sexual activities. 3. Go to bed only when feeling sleepy at night or at the designated sleep time. 4. If unable to fall asleep within approximately 20 minutes of being in bed, leave the bedroom, engage in relaxing activities, and return to bed when feeling sleepy. Repeat this process if unable to fall asleep within approximately 20 minutes. 5. Wake up at the same time every morning, including weekends.

1. Sleep until feeling refreshed the next day. 2. Maintain regular exercise and eating habits, avoiding going to bed on an empty stomach. 3. Ensure a comfortable bedroom environment with suitable nighttime temperature, free from light and noise disturbances. 4. Avoid excessive consumption of beverages, alcohol, and smoking at night, and reduce caffeine intake. 5. Avoid bringing problems to bed and refrain from attempting to sleep. 6. Place the alarm clock under the bed or move it away from sight. 7. Avoid daytime napping.
