Improving Patient Sleep Prior to Elective Surgery

The goal of this clinical trial is to learn if changing sleep behaviour can improve sleep health in patients undergoing prehabilitation before elective surgery. Prehabilitation is the use of exercise, nutrition, and psychological support before surgery to improve recovery from surgery. The main questions it aims to answer are: Does changing sleep behaviour improve sleep before surgery? Does changing sleep behaviour improve recovery after surgery? Researchers will compare participants who receive sleep support with participants who do not receive sleep support to see if it improves sleep health and recovery from surgery. Participants will be asked to attend 4 meetings with the research team to learn how they can improve their sleep. They will use questionnaires, a diary, and a wearable tracker to record their sleep.
