The Effect of Aromatherapy on Anxiety in Patients

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. This study aimed to investigate the effect of inhaling rose water aromatherapy on anxiety in hemodialysis patients. 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. 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). 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.
