This study examined the effect of auricular acupuncture therapy on the stress and sleep status of middle-aged women in South Korea ⁽¹⁾. 67 women were in the study. Auricular acupuressure therapy including the auricular acupressure needle on the skin paper tape was applied on an ear for 2 weeks, 2 times per week. The acupoints were Gyogam, Sinmun, Bushin, Naebunbi, and Pijilha. For the placebo control group, only the skin paper tape without the auricular acupressure needle was applied on the same acupoints. Measures were a stress scale, cortisol level in blood, and a sleep status scale. The results showed that there were significant differences on stress, cortisol level in blood, and sleep status.
