Optimizing an Integrated Mind and Body Treatment for Insomnia: The SLEEPS Study

Digital cognitive behavioral therapy for insomnia (CBT-I) is a behavioral (psychotherapeutic) intervention for insomnia disorder. Participants will complete digital CBT-I online using the Sleep Healthy Using the Internet (SHUTi) program.

Passive body heating (PBH) is a body-based treatment that participants will complete using a sauna blanket, which is similar in form factor to an adult-sized sleeping bag (head is not within the heated area). Participants will complete at least three 15-minute PBH sessions per week. Participants will complete PBH sessions in the sauna blanket placed on the floor or on a couch (i.e., not in their bed) at a setting of Level 6, 1-2 hours before bed.
