OBJECTIVES:Nursing home (NH) residents suffer from sleep disturbances which are associated with a low quality of life (QoL). The purpose of this study was to explore the effectiveness of comparing acupressure on specific acupoints with acupressure on non-specific acupoints in older NH residents with sleep disturbances.

DESIGN:A randomized control trial with a pre- and post-test design.

SETTING:One NH in Taiwan.

PARTICIPANTS:Sixty-two older NH residents were randomly assigned to an experimental group (n = 31) and a sham-controlled group (n = 31).

INTERVENTION:The experimental group received acupressure on the Tian-Zhu, Ju-Que, Yong-Quan, Bai-Hui, and Nei-Guan acupoints three times a week for 8 weeks, for 24 minutes each time, while the control group received a massage at locations with no acupoints, which were 10 mm from the true points, at the same frequency as the experimental group.

MEASUREMENTS:The primary outcome was measured using the Pittsburgh Sleep Quality Index (PSQI) and the secondary outcome was measured using the Short-form 36 (SF-36). Data were collected at baseline, the end of treatment, and 4 weeks after completion of treatment.

RESULTS:Compared to the control group, the experimental group had significantly better scores on the PSQI (t = -7.72, P<0.001) and SF-36 (t = 1.34, P<0.001) during the intervention period. The improvements in the PSQI and SF-36 scores were still significant (P<0.001) after adjusting for confounding variables by generalized estimating equations.

CONCLUSIONS:Results suggest that acupressure on the Tian-Zhu, Ju-Que, Yong-Quan, Bai-Hui, and Nei-Guan acupoints can improve the quality of sleep and life among NH residents. Acupressure is a promising intervention that may improve well-being for NH residents with sleep disturbances.

BACKGROUND:Sensory isolation in a flotation tank is a method known for inducing deep relaxation and subsequent positive health effects for patients suffering from e.g. stress or muscle tensions pains. Very few studies have investigated this method as a preventive health-care intervention. The purpose of this study was to evaluate the effects in healthy participants after receiving a series of flotation tank treatment.

METHODS:Sixty-five participants (14 men and 51 women) who were all part of a cooperative-health project initiated by their individual companies, were randomized to either a wait-list control group or a flotation tank treatment group where they participated in a seven weeks flotation program with a total of twelve flotation sessions. Questionnaires measuring psychological and physiological variables such as stress and energy, depression and anxiety, optimism, pain, stress, sleep quality, mindfulness, and degree of altered states of consciousness were used. Data were analysed by two-way mixed MANOVA and repeated measures ANOVA.

RESULTS:Stress, depression, anxiety, and worst pain were significantly decreased whereas optimism and sleep quality significantly increased for the flotation-REST group. No significant results for the control group were seen. There was also a significant correlation between mindfulness in daily life and degree of altered states of consciousness during the relaxation in the flotation tank.

CONCLUSIONS:It was concluded that flotation-REST has beneficial effects on relatively healthy participants.

AIMS AND OBJECTIVES:The aim of this study was to investigate the effects of a cognitive behavioural intervention combined with a breathing relaxation exercise on sleep quality and heart rate variability in patients with major depression.

BACKGROUND:Depression is a long-lasting illness with significant effects not only in individuals themselves, but on their family, work and social relationships as well. Cognitive behavioural therapy is considered to be an effective treatment for major depression. Breathing relaxation may improve heart rate variability, but few studies have comprehensively examined the effect of a cognitive behavioural intervention combined with relaxing breathing on patients with major depression.

DESIGN:An experimental research design with a repeated measure was used.

METHODS:Eighty-nine participants completed this study and entered data analysed. The experimental group (n = 43) received the cognitive behavioural intervention combined with a breathing relaxation exercise for four weeks, whereas the control group (n = 46) did not. Sleep quality and heart rate variability were measured at baseline, posttest1, posttest2 and follow-up. Data were examined by chi-square tests, t-tests and generalised estimating equations.

RESULTS:After adjusting for age, socioeconomic status, severity of disease and psychiatric history, the quality of sleep of the experimental group improved, with the results at posttest achieving significance. Heart rate variability parameters were also significantly improved.

CONCLUSIONS:This study supported the hypothesis that the cognitive behavioural intervention combined with a breathing relaxation exercise could improve sleep quality and heart rate variability in patients with major depression, and the effectiveness was lasting.

RELEVANCE TO CLINICAL PRACTICE:The cognitive behavioural intervention combined with a breathing relaxation exercise that included muscle relaxation, deep breathing and sleep hygiene could be provided with major depression during hospitalisation. Through group practice and experience sharing, participants could modulate their heart rate variability and share feeling about good sleep as well relaxation.

ETHNOPHARMACOLOGICAL RELEVANCE:Cannabis sativa L. (C. sativa) is an annual dioecious plant, which shares its origins with the inception of the first agricultural human societies in Asia. Over the course of time different parts of the plant have been utilized for therapeutic and recreational purposes, for instance, extraction of healing oils from seed, or the use of inflorescences for their psychoactive effects. The key psychoactive constituent in C. sativa is calledΔ-9-tetrahydrocannabinol (D9-THC). The endocannabinoid system seems to be phylogenetically ancient, as it was present in the most primitive vertebrates with a neuronal network. N-arachidonoylethanolamine (AEA) and 2-arachidonoyl glycerol (2-AG) are the main endocannabinoids ligands present in the animal kingdom, and the main endocannabinoid receptors are cannabinoid type-1 (CB1) receptor and cannabinoid type-2 (CB2) receptor.

AIM OF THE STUDY:The review aims to provide a critical and comprehensive evaluation, from the ancient times to our days, of the ethnological, botanical, chemical and pharmacological aspects of C. sativa, with a vision for promoting further pharmaceutical research to explore its complete potential as a therapeutic agent.

MATERIALS AND METHODS:This study was performed by reviewing in extensive details the studies on historical significance and ethnopharmacological applications of C. sativa by using international scientific databases, books, Master's and Ph.D. dissertations and government reports. In addition, we also try to gather relevant information from large regional as well as global unpublished resources. In addition, the plant taxonomy was validated using certified databases such as Medicinal Plant Names Services (MPNS) and The Plant List.

RESULTS AND CONCLUSIONS:A detailed comparative analysis of the available resources for C. sativa confirmed its origin and traditional spiritual, household and therapeutic uses and most importantly its popularity as a recreational drug. The result of several studies suggested a deeper involvement of phytocannabinoids (the key compounds in C. sativa) in several others central and peripheral pathophysiological mechanisms such as food intake, inflammation, pain, colitis, sleep disorders, neurological and psychiatric illness. However, despite their numerous medicinal benefits, they are still considered as a menace to the society and banned throughout the world, except for few countries. We believe that this review will help lay the foundation for promoting exhaustive pharmacological and pharmaceutical studies in order to better understand the clinical relevance and applications of non-psychoactive cannabinoids in the prevention and treatment of life-threatening diseases and help to improve the legal status of C. sativa.

PURPOSE OF REVIEW:The current review aims to summarize the state of research on cannabis and sleep up to 2014 and to review in detail the literature on cannabis and specific sleep disorders from 2014 to the time of publication.

RECENT FINDINGS:Preliminary research into cannabis and insomnia suggests that cannabidiol (CBD) may have therapeutic potential for the treatment of insomnia. Delta-9 tetrahydrocannabinol (THC) may decrease sleep latency but could impair sleep quality long-term. Novel studies investigating cannabinoids and obstructive sleep apnea suggest that synthetic cannabinoids such as nabilone and dronabinol may have short-term benefit for sleep apnea due to their modulatory effects on serotonin-mediated apneas. CBD may hold promise for REM sleep behavior disorder and excessive daytime sleepiness, while nabilone may reduce nightmares associated with PTSD and may improve sleep among patients with chronic pain. Research on cannabis and sleep is in its infancy and has yielded mixed results. Additional controlled and longitudinal research is critical to advance our understanding of research and clinical implications.

OBJECTIVE:The aim of this study was investigating the effect of 12 weeks of yoga and aerobic exercise (running on a treadmill) on the sleep quality in women with Type 2 diabetes.

MATERIALS AND METHODS:39 diabetic women were selected from Semnan city with the mean age of 46.85±3.35 years, weight of 69.79±17.18 kg, height of 155.03±5.00, BMI of 29.64±5.00 kg/m(2) who had a background of diabetes for 6.46±2.69 years. They were then randomly divided into yoga exercise (n=15), aerobic exercise (n=13), and control group (n=11). The exercise program was performed for 12 weeks, three sessions per each week. In order to measure the sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used. The data were analyzed by non-parametric wilcoxon and Kruskal-Wallis Test at significance level of p<0.05.

RESULTS:Overall score of sleep quality improved after six (p=0.001) and 12 (p=0.001) weeks of yoga exercise. Also, significant effect was observed after 6 weeks of aerobic exercise (p=0.039). However, the positive effect was diminished to under significant levels after 12 weeks of aerobic exercise (p=0.154). Kruskal-Wallis Test showed significant differences between yoga and aerobic groups after 12 weeks of exercise (p=0.002). No significant differences were observed in control groups in all situation.

CONCLUSIONS:It can be concluded that yoga exercise is more effective in improving the sleep quality in comparison with the same course of aerobic exercise in women suffering from diabetes Type 2. Thus, yoga exercise can be suggested to these patients.

This review aimed to evaluate the effectiveness of acupressure in promoting sleep quality among adults. Study findings included in the review showed that acupressure significantly improved sleep quality compared with the control group, but no superior effect of acupressure was found compared with sham acupressure.

The objective of this study was to determine the effect of 16 weeks of mat-based Pilates training on health perception and sleep quality among elderly women. A randomized and controlled trial was conducted in Caxias do Sul, Brazil, in 2015, in which 61 healthy older women were divided into two groups: experimental group (EG; n=31, average of 64.25 years old, SD 0.14) and control group (CG; n=30, average of 63.75 years old, SD 0.08). The EG participants performed mat-based Pilates exercises twice a week in 60-min sessions, whereas the CG did not train. All participants completed Brazilian-adapted and validated versions of the Pittsburgh Sleep Quality Index (PSQI-BR) and General Health Questionnaire (GHQ-12) at baseline and after 16 weeks. Significant time x group interaction effects were found for the GHQ-12 total score (p<0.001,η=0.19), and the depression (p=0.002,η=0.15) and social dysfunction subscales (p=0.001,η=0.18), as well as the PSQI-BR total score (p=0.017,η=0.09), and the sleep latency (p=0.023,η=0.09) and use of sleeping medication subscales (p=0.019,η=0.09), indicating better improvements (reductions) in these outcome variables for the Pilates EG when compared to the CG. All significant effects were classified as moderate to high. These results indicate that 16 weeks of mat-based Pilates training significantly improves the perceived health status and some sleep quality indices among elderly women. However, more studies are needed to assess the effectiveness of equipment-based Pilates exercises among this population.

BACKGROUND:In intensive care units (ICUs), patients cannot sleep well. Aromatherapy is used for depression, anxiety, relaxation and disorders related with sleep and stress.

AIM:This study aimed to investigate the effect of lavender essential oil on the sleep quality and anxiety level of patients in coronary ICU.

PARTICIPANTS:A total of 60 patients in coronary ICU participated in this study.

DESIGN:A randomized controlled study was conducted with 60 patients in a province located in the southeast of Turkey.

METHODS:After informing the patients in both groups about the study, they were administered a questionnaire, Pittsburgh Sleep Quality Index (PSQI) and the Beck Anxiety Inventory (BAI) scale. The patients in the intervention group were given 2% lavender essential oil via inhalation for 15 days after which they were administered the same scales again to evaluate the sleep quality and anxiety. As for the control group, they were administered the same scales again after 15 days without the inhalation of lavender essential oil.

RESULTS:Comparison of the PSQI and BAI scores of the patients in the control and intervention groups before and after the intervention showed statistically significant differences in the change in favour of the intervention group (p<0·05).

CONCLUSION:Lavender essential oil increased quality of sleep and reduced level of anxiety in patients with coronary artery disease.

RELEVANCE TO CLINICAL PRACTICE:As a non-invasive, cheap, easily applicable, cost-effective, independent nursing intervention and appropriate for cardiac patients, lavender essential oil could be applied in ICUs.

One of the problems of cancer patients is sleep disorder. Given the absence of studies on comparing the effect of inhalation aromatherapy with lavender and peppermint on the sleep quality of the cancer patients, this study was performed to compare the effect of inhalation aromatherapy with lavender and peppermint essential oils on the sleep quality of cancer patients. For this purpose, 120 patients were randomly allocated to three groups of lavender, peppermint, and control. The intervention groups received three drops of the essential oil for 7 days. In the control group, aromatic distilled water was used instead. Pittsburgh Sleep Quality Inventory (PSQI) was used. Before the intervention, no significant difference was observed between the mean PSQI scores of three groups, while the difference was statistically significant after the intervention. The mean PSQI scores were lower in lavender and peppermint groups than in the control group. Aromatherapy can improve the sleep quality of cancer patients. To confirm the findings, more studies should be done.

BACKGROUND:Students in 2-year registered nurse to Bachelor of Science in nursing (RN-BSN) programs usually work full-time and study part-time. Sleep disturbance, anxiety, and depression are known to be common health problems among these students. Prior research has described the effectiveness of auricular acupressure (AA) in reducing sleep disturbance and improving mood.

PURPOSE:The aim of this study was to evaluate the effect of using a 4-week AA program that adheres to a magnetic pellet on the shenmen acupoint on sleep quality, anxiousness, and depressed moods in nursing students with sleep disturbance.

METHODS:This study used a one-group, quasi-experimental design with repeated measures. Eligible students were recruited from an RN-BSN program offered by a university in northern Taiwan, and all were currently experiencing sleep disturbance. A 4-week AA intervention that applied a magnetic pellet on the shenmen acupoint was used. The Pittsburgh Sleep Quality Index, Beck Anxiety Inventory, and Beck Depression Inventory-II were used to measure sleep quality and mood outcomes each week during the 4-week intervention. Improvements in sleep quality, anxiety, and depressed moods were analyzed using the generalized estimating equation.

RESULTS:Thirty-six participants with a mean age of 32 years were enrolled as participants. After adjusting for confounding factors, continuous and significant improvements in sleep quality, anxiety, and depressed mood (p<.05) were observed throughout the intervention, with 4-week improvements in sleep quality, anxiety, and depressed mood averaging 26.7%, 43.5%, and 25%, respectively.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE:This study showed the efficacy of using a 4-week AA that applies a magnetic pellet on the shenmen acupoint in terms of improving sleep quality, anxiousness, and depressed mood in RN-BSN students experiencing sleep disturbances. Especially, the emotional mood of participants improved significantly as early as the first week. The 4-week AA for reducing sleep disturbance, and improving students' anxiety, and depressed moods may be applied on primary healthcare.

This study sought to examine the effect of auricular acupressure therapy on the stress and sleep status of middle-aged women in South Korea. A quasi-experimental pretest/posttest control group design was employed. The study sample consisted of 67 middle-aged women (experimental: 35 samples; control: 32 samples) in Seoul, South Korea. Auricular acupressure therapy including the auricular acupressure needle on the skin paper tape was applied on an ear for 2 weeks, 2 times per week. The acupoints were Gyogam, Sinmun, Bushin, Naebunbi, and Pijilha. For the placebo control group, only the skin paper tape without the auricular acupressure needle was applied on the same acupoints. Measures were a stress scale, cortisol level in blood, and a sleep status scale. The findings showed that there were significant differences on stress (physical: t = 2.170, P<.033; psychological: t = 2.117, P<.037), cortisol level in blood (t = 2.277, P<.025), and sleep status (t = -3.127, P<.004). Health care providers should consider providing auricular acupressure therapy as an alternative method for reducing physical and psychological stress, cortisol level in blood, and sleep disturbance of middle-aged women in South Korea.

STUDY OBJECTIVES:Chronic sleep onset insomnia with late melatonin onset is prevalent in childhood, and has negative daytime consequences. Melatonin treatment is known to be effective in treating these sleep problems. Bright light therapy might be an alternative treatment, with potential advantages over melatonin treatment. In this study, we compare the effects of melatonin and bright light treatment with a placebo condition in children with chronic sleep onset insomnia and late melatonin onset.

METHODS:84 children (mean age 10.0 years, 61% boys) first entered a baseline week, after which they received melatonin (N=26), light (N=30), or placebo pills (N=28) for three to four weeks. Sleep was measured daily with sleep diaries and actigraphy. Before and after treatment children completed a questionnaire on chronic sleep reduction, and Dim Light Melatonin Onset (DLMO) was measured. Results were analysed with linear mixed model analyses.

RESULTS:Melatonin treatment and light therapy decreased sleep latency (sleep diary) and advanced sleep onset (sleep diary and actigraphy), although for sleep onset the effects of melatonin were stronger. In addition, melatonin treatment advanced DLMO and had positive effects on sleep latency and sleep efficiency (actigraphy data), and sleep time (sleep diary and actigraphy data). However, wake after sleep onset (actigraphy) increased with melatonin treatment. No effects on chronic sleep reduction were found.

CONCLUSIONS:We found positive effects of both melatonin and light treatment on various sleep outcomes, but more and stronger effects were found for melatonin treatment.
