Memorial University launched a new smartphone application, iCANSleep, on February 22, 2026, designed to address insomnia among cancer survivors. The app delivers cognitive behavioural therapy (CBT-I) and is the result of four years of research and development.

Dr. Sheila Garland, a Clinical Psychologist and Associate Professor of Psychology and Oncology at Memorial University of Newfoundland, is leading the clinical trial. According to Dr. Garland, up to 60 per cent of cancer survivors experience difficulties with sleep, yet access to specialized treatment remains limited. “We grasp that insomnia is a really common problem for cancer survivors, and yet there aren’t a lot of options available to them,” she stated.

iCANSleep aims to bridge this gap by providing personalized CBT-I through a mobile platform, potentially overcoming geographical barriers and limited access to trained professionals. The app is intended to be more effective than medication for long-term sleep improvement, according to Dr. Garland.

The iCANSleep app is currently seeking participants for a study. Eligibility criteria include a previous cancer diagnosis, difficulty falling or staying asleep, being at least 18 years ancient, iPhone ownership, Canadian residency, and being at least three months post-treatment or clinically stable. Participation involves a seven-week app-based CBT-I program and completion of four to six short surveys.

The Sleep, Health, & Wellness Lab at Memorial University, where Dr. Garland’s research is based, can be contacted at (403) 505-0419 or (709) 864-8035, or via email at [email protected]. Questions regarding research participant rights can be directed to the Health Research Ethics Authority at (709) 777-6974 or [email protected].

Katherine-Ann Piedalue, a Doctoral student working under Dr. Garland’s supervision, is examining the feasibility and acceptability of the iCANSleep App. Rachel Lee, another Doctoral student, is investigating the efficacy and long-term durability of the app in addressing insomnia symptoms among cancer survivors.
