The Effect of Aromatherapy on Anxiety in Patients.

Background: Anxiety is the most common mental disorder in end-stage renal disease patients. The use of aromatherapy as a treatment for anxiety has increased substantially in most countries.
Objectives: This study aimed to investigate the effect of inhaling rose water aromatherapy on anxiety in hemodialysis patients.
Methods: This randomized controlled clinical trial was carried out in the hemodialysis ward of Birjand Vali-Asr hospital on 46 patients who were randomly divided into control and experimental groups. The standard state-trait anxiety inventory of Spielberger was used to investigate the anxiety level of the samples. The experimental group inhaled rose water for 4 weeks, but the control group did not undergo any intervention. At the end of week 2 and week 4, the participants' anxiety was measured, and the results were statistically analyzed.
Results: Mean scores of state and trait anxiety in the experimental group before intervention were 47/47 ± 7/6 and 49/56 ± 13/8, respectively; those after week 4 following the intervention were reduced to 37/1 ± 6/5 and 42/9 ± 10/1; inhalation of rose water fragrance in the experimental group caused a significant decrease (P < 0.001) in the state and trait anxiety levels compared with controls (P = 0.43).
Conclusions: According to the present study, rose water noticeably reduces the anxiety of hemodialysis patients. Therefore, inhalation of rose water can improve the patient's emotional and spiritual condition during hemodialysis treatment.
