This study will be conducted to investigate the effects of hot foot baths on patients' sleep quality and fatigue severity levels.The study will be conducted in the Gastroenterology clinic of a university hospital in Türkiye. The research sample will consist of 60 adult patients. Patients will be randomly divided into two groups: the intervention and control groups. The intervention group will receive hot foot baths for three consecutive nights starting from the second day of hospitalization. The foot bath will be applied one hour before the patient goes to bed at night. The foot tub will be filled with hot water to approximately 20 cm above the patient's ankle and the temperature of the water will be measured with a water thermometer. The temperature of the water will be kept stable at 41-42°C. This application will be done for 20 minutes. The sleep and fatigue levels of the patients will be measured with measurement tools in the morning (3 times) following each application. No application will be applied to the control group, and sleep and fatigue levels will be measured in a similar manner to the measurement tools applied to the intervention group and the application days.
