Background:
Auriculotherapy may activate the parasympathetic nerve system and reduce anxiety levels. Short-term auriculotherapy's effects and safety on university students' anxiety levels was assessed prior to exams.
Methods:
A randomized, controlled pilot trial was conducted. The day before the exam, university students were randomly allocated to the auriculotherapy group (AA, n = 13) or the waiting-list group (WG, n = 13). Baseline measures were taken 4 weeks before the exam at Time point (TP 0); at 7.30 a.m. on the day before the exam (TP I); at 11 a.m. before auriculotherapy (TP II); 30 min after AA (TP III); and at 7.30 a.m. before the exam (TP IV). The outcomes were the State-Trait-Anxiety Inventory (STAI); quality of night-sleep, Visual Analogue scale (VAS) for anxiety, and salivary cortisol. Adverse events were also recorded.
Results:
A total of 26 students participated in this study and became more anxious as assessed by STAI in TPII (p = 0.002) and TPIV (p = 0.000) than TP0. AA reduced the STAI in TPIII (p = 0.045) and PIV (p = 0.001) and the VAS (p = 0.012) in TPIV. Cortisol was reduced in TPIII (p = 0.004), and the AA slept better (p = 0.014) at TPIV. Discomfort at the auricular site was reported in only one AA participant.
Conclusions:
Auriculotherapy appeared safe and effective in reducing anxiety levels before university exams.

Anxiety: Overview
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
