Self-administered Acupressure for Insomnia Disorder

Subjects in the self-administered acupressure group will attend an acupressure training course (2 sessions, 2 hours each) to learn self-administered acupressure, which will then be performed every night for 4 weeks.

Subjects in the comparison group will receive sleep hygiene education (2 sessions, 2 hours each, same as the treatment group) and be reminded to follow the sleep hygiene practice daily for 4 weeks.
