BACKGROUND: Labor and delivery is a stressful stage for mothers. During these periods, sleep-related disorders have been reported. The problems of inadequate sleep include decrease in concentration, judgment, difficulty in performing daily activities, and an increase in irritability. Even the effects of moderate sleep loss on life and health quality can be similar to sleep deprivation. some research aggravated by aromatherapy on sleep quality in different periods of life so might be useful for the improve of sleep quality in postpartum women.
OBJECTIVES: This study aimed to determine the effect of aromatherapy on the quality of sleep in postpartum women. The sample was recruited from medical health centers of Zanjan University of Medical Sciences.
PATIENTS AND METHODS: This study was a randomized clinical trial with the control group. A total of 158 mothers in postpartum period (with certain inclusion criteria) were enrolled in the study and assigned randomly to two groups of control and intervention. Lavender fragrance (made by Barij Essence Pharmaceutical Co.) was used by participants in the intervention group nightly before sleeping. The fragrance was dropped on cotton balls, which were placed on a cylindrical container at mothers' disposal. Keeping the container at a projected distance of 20 cm, the participants inhaled 10 deep breaths and then the container was placed beside their pillow until morning. This procedure was done 4 times a week for 8 weeks. For the control group, the same intervention was done with the placebo. The instrument for collecting data was Pittsburgh sleep quality index, which was completed at the baseline, fourth, and eighth weeks after the intervention. Data were analyzed using independent t test and repeated measures analysis of variance calculated by SPSS16.
RESULTS: Before the intervention, there were no significant differences between mothers in two groups (P > 0.05). After 8 weeks follow up, a significant improvement appeared in mothers' sleep quality in the intervention group. Aromatherapy increased sleep quality mean score (±SD) from 8.2911 (± 2.1192) to 6.7975 (± 2.3663) (P < 0.05), but in the control group sleep quality mean score (±SD) changes from 8.4557 (± 2.3027) to 7.5696 (± 1.1464) (P > 0.05). Comparing sleep quality between control and intervention groups after 8 weeks from the beginning of the intervention indicated that aromatherapy was effective in the improvement of mothers' sleep quality (P < 0.05).
CONCLUSIONS: Considering the effects of aromatherapy on the improvement of mother's sleep quality during postpartum period, aromatherapy has been suggested as a non-pharmacological method for the improvement of maternal health.
