How to practice CBT-I (Cognitive Behavioral Therapy for Insomnia)
For persistent insomnia (≥3 months), seek a certified CBT-I provider or digital program. Expect 4–8 sessions covering sleep restriction, stimulus control, cognitive restructuring, and relaxation. Short-term fatigue during sleep restriction is normal. Benefits typically appear within weeks and last for years.
The evidence behind CBT-I (Cognitive Behavioral Therapy for Insomnia)
Dozens of RCTs confirm CBT-I produces large, durable improvements in sleep onset, duration, and efficiency, matching or surpassing medications long-term. Mechanism: reduces conditioned hyperarousal and maladaptive sleep beliefs, stabilizing circadian and homeostatic processes. Strong evidence for people with insomnia; unnecessary for good sleepers.
