Many college students have a habit of taking naps, yet few studies have investigated the issue of napping among college students from the perspective of wearable sleep intervention devices. The study aimed to explore the impact of two sleeping postures (sitting in a chair and lying on a bed) and two sleep intervention methods (Eye-Massaging and Hand-Held Microcurrent Stimulation) on the nap performance of college students. This experiment recruited undergraduate and graduate students with nap habits to conduct in-dormitory nap experiments. The results revealed that the group using chairs exhibited longer nap durations, higher sleep quality, and lower afternoon fatigue on the day of the nap. However, significant individual differences in response to the two intervention devices were observed, which could be attributed to varying degrees of adaptability to new devices among participants. The participants’ research and work pressures also influenced nap quality. Therefore, it is recommended that sleep intervention device design should focus on features such as low noise and lightweight, along with incorporating gentle awakening functions. Future experiments should aim to recruit more participants from the same academic level, extend nap durations and experimental periods, control stress variables, and further investigate the impacts of different wearable sleep intervention devices.
