Outline of Final Research Achievements |
Daytime sleepiness is reportedly associated with depression and poor academic performance. This study aimed to examine the effect of self-care using transcutaneous vagus nerve stimulation (taVNS) in college students with sleepiness and depression. Thirty-four college students were assigned to a control or taVNS group. Daytime sleepiness, depression, study engagement, and sleep quality were measured using the ESS-J, BDI-II-J, UWES-S-J, PSQI-J, and Silmee. Autonomic nervous system activities were measured using heart rate variability. The change in each group from day 28 to day 1 was calculated and analyzed. The ESS-J, BDI-II-J, UWES-S-J, and PSQI-J (sleep quality and daytime dysfunction) scores improved, and the LF/HF ratio (sympathetic nervous system) decreased in the taVNS group compared with the control group. Self-care using taVNS suppresses the sympathetic nervous system during sleep, which may improve sleep quality, daytime sleepiness, depression, and study engagement.
