Abstract

Aromatherapy effectively reduces stress, anxiety, and improves sleep quality across various populations. Multiple systematic reviews and randomized controlled trials consistently demonstrate its therapeutic potential. Studies show benefits for nursing students, healthy adults, preoperative patients, university students, nurses facing occupational stress—including during the COVID-19 Pandemic—postpartum women, and individuals experiencing chronic stress. Lavender essential oil is frequently highlighted for its efficacy. This intervention offers a safe, non-pharmacological, and accessible complementary approach for managing psychological distress and enhancing overall well-being.
