The Effect of Virtual Reality Glasses and Breathing Exercise on Anxiety

Cancer remains one of the leading causes of morbidity worldwide, with anxiety recognized as one of the most frequently reported psychological symptoms among patients undergoing chemotherapy. In breast cancer patients specifically, anxiety has been shown to negatively affect quality of life, reduce treatment adherence, and intensify the perceived burden of other physical symptoms during chemotherapy sessions. While pharmacological approaches remain part of standard symptom management, non-pharmacological interventions-such as distraction techniques, relaxation exercises, guided imagery, and music therapy-are increasingly used by nurses due to their low cost, safety, ease of implementation, and ability to actively engage patients in their own care. Among these, virtual reality (VR) technology has emerged as a promising distraction-based intervention, with prior studies reporting reductions in stress, anxiety, and treatment-related discomfort. Similarly, breathing exercises have demonstrated anxiolytic effects through their regulatory influence on the autonomic nervous system, with recent systematic reviews and meta-analyses confirming significant reductions in anxiety and depression among cancer patients. Despite the individual evidence supporting each intervention, few studies have directly compared the effectiveness of virtual reality glasses and breathing exercises within the same patient population, and randomized controlled trials evaluating both interventions concurrently in breast cancer patients undergoing chemotherapy remain limited. This study is designed as a randomized controlled trial to determine and compare the effects of virtual reality glasses and breathing exercise applications on anxiety levels in breast cancer patients receiving chemotherapy. Eligible participants will be randomly assigned to one of the study groups (virtual reality glasses, breathing exercise, or standard care/control), and anxiety will be assessed using a validated anxiety measurement instrument (State-Trait Anxiety Inventory, VAS) before and after the intervention during chemotherapy sessions.The findings of this study are expected to contribute to the evidence base for non-pharmacological anxiety management in oncology nursing practice and to help identify effective, low-cost interventions that can be integrated into routine chemotherapy care.
