Sleep Restriction

Sleep Restriction Therapy (SRT) is an effective and widely used technique in the treatment of insomnia. It is commonly applied as part of a multicomponent cognitive-behavioral therapy for insomnia (CBT-I) but has also been linked to beneficial effects as a stand-alone intervention. SRT reduces insomnia symptoms and consolidates sleep through the management of homeostatic sleep drive and circadian rhythm. Key points of SRT consists of filling up a sleep diary; sleep psychoeducation; and definition and titration of a sleep window. SRT application should be carried out by a sleep specialist to promote a safe intervention and better sleep pattern, preserving adherence. The SRT is not a simple application of techniques, it asks for a wide and deep knowledge about sleep and psychological interventions.
