“…Aromatherapy is one of the treatments that have grown increasingly in recent years compared to complementary medicine treatments [ 18 ]. According to a recent systematic review, various essential oils, such as lavender, bergamot, and chamomile, have improved sleep quality and reduced stress, pain, anxiety, depression, and fatigue [ 19 ]. These oils help individuals to relax their bodies and minds, leading to better sleep quality.…”

Sleep disorder is very common during pregnancy. Non-pharmacological treatments are a priority to improve the sleep pattern. This study aimed to determine the effect of cognitive–behavioral counseling with or without Citrus aurantium essential oil on sleep quality (primary outcome) and anxiety and quality of life (secondary outcomes). This randomized controlled trial was performed on 75 pregnant women in Tabriz, Iran. Participants were randomly assigned to the intervention and control groups. The first intervention group received 8 sessions of cognitive–behavioral counseling and aromatherapy with Citrus aurantium essential oil 15–20 min before bedtime. The second intervention group received cognitive–behavioral counseling and aromatherapy with placebo and the control group received only routine prenatal care. Pittsburgh Sleep Quality Index, Pregnancy-Specific Quality of life Questionnaire, and Pregnancy-Specific Anxiety Scale were completed before and after intervention. After the intervention based on ANCOVA test and by adjusting the baseline score, the mean score of anxiety in the intervention group 1 (AMD: − 4.54; 95% CI − 6.79 to − 2.28) and intervention group 2 (AMD: − 3.30; 95% CI − 5.60 to − 0.97) was significantly lower than the control group. Also, the mean score of quality of life in intervention group 1 (AMD: 2.55; 95% CI 0.45–4.65) and intervention group 2 (AMD: 2.72; 95% CI 0.60–4.83) was significantly higher than the control group, but there was no statistically significant difference between the study groups in terms of sleep quality ( P > 0.05). Also, there was no statistically significant difference between the two intervention groups after the intervention in terms of anxiety ( P = 0.379) and quality of life ( P = 0.996). Cognitive–behavioral counseling reduced anxiety and improved quality of life. However, further trials are required to reach a definitive conclusion.

“…Although the effect size was reduced to medium, the associated CI remained statistically significant. Previous meta-analyses of studies evaluating various non-pharmacological sleep interventions in older adults, including exercise [ 27 , 28 ], aromatherapy [ 25 , 26 ], meditation [ 29 ], and CBT [ 9 ] also reported the efficacy of non-pharmacological sleep interventions. However, many older adults still suffer from sleep problems.…”

“…In the Republic of Korea, a recent systematic review evaluated the effects of non-pharmacological interventions in older adults [ 24 ]. Some meta-analyses have been performed on the effects of specific interventions, including aromatherapy [ 25 , 26 ], exercise [ 27 , 28 ], meditation [ 3 , 29 ], and auricular acupressure [ 30 ]. To our knowledge, no previous systematic reviews globally have formally analyzed the effects of non-pharmacological interventions on sleep in older adults.…”

This study investigated the effects of non-pharmacological interventions on sleep in older people through a systematic review and meta-analysis. We conducted a literature search using eight electronic databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Participant characteristics, the contents of the evaluated interventions, and the measured outcomes were systematically reviewed for 15 selected studies. We performed a meta-analysis to estimate the effect size for overall, aggregated sleep outcomes. Due to the small number of studies available for each intervention, only the overall effectiveness of non-pharmacological sleep interventions was evaluated. The evaluated interventions included exercise, aromatherapy, acupressure, cognitive behavior therapy, and meditation. Our results demonstrated that non-pharmacological interventions showed statistically significant effects on sleep (effect size = 1.00, 95% confidence interval: 0.16, 1.85, I2 = 92%, p < 0.001). After confirming publication bias and removing outliers, we found no heterogeneity (I2 = 17%, p = 0.298), with a decrease in effect size to 0.70 (95% confidence interval: 0.47, 0.93). Non-pharmacological interventions are effective for improving sleep in older adults. Future studies should continue to investigate sleep problems and interventions addressing these problems in this demographic, particularly in older women. Objective measures should be used to follow-up on the evaluated sleep interventions over the long term.

College students, particularly female students, often suffer from severe stress and poor sleep. Aromatherapy yoga has become a popular exercise in recent years and may help reduce stress and improve sleep quality, although empirical evidence is limited. We investigated the effectiveness of aromatherapy yoga intervention in reducing stress and improving sleep quality among Chinese female college students. A total of 89 participants—44 in the experimental group (aromatherapy yoga) and 45 in the control group (yoga)—with an average age of 19.88 ± 1.13 years, were enrolled in this quasi-experimental study. Interventions were performed in the respective groups once a week for 12 weeks, for 90 min each time. The Wilcoxon signed-rank test and Mann–Whitney U test (including effect size) were used to test the differences in stress reduction and sleep quality before and after the intervention. From the findings of the current research, both therapies did not help female students’ stress levels or sleep hygiene significantly. However, aromatherapy yoga has the potential to improve sleep disturbances experienced by female college students. Additionally, there was no difference in the amount of stress or the quality of sleep between the aromatherapy yoga groups and the regular yoga groups before and after therapy.
