Sleep problems in PTSD patients are a complex interplay of anticipatory anxiety about nightmares, hyperarousal, and arousal responses during sleep. Stimulus control techniques in CBT-I (Cognitive Behavioral Therapy for Insomnia) involve conditioning the bed to be a space solely for sleep, while sleep restriction therapy involves adjusting the time spent lying in bed to actual sleep time. The basics involve turning off smartphones and news for an hour before bed, dimming indoor lights, and maintaining a regular rhythm of lying down and waking up at the same time. Dongjedang recommends applying pressure to the Heart and Pericardium meridian acupoints on the inside of the wrist for 3 to 5 minutes daily before sleep. Drinking wild jujube seed tea, which has calming properties, one hour before bedtime also helps improve sleep quality. If nightmares occur very frequently, we advise combining this with professional psychotherapy (Image Rehearsal Therapy/IRT).
