Effects of aromatherapy on stress, fructosamine, fatigue, and sleep quality in prediabetic middle-aged women: A randomised controlled trial

A scoping review of olfactory interventions for fatigue relief: addressing occupational health hazards

Background

Fatigue poses risks to occupational health and safety, affecting individuals' work efficiency, physical health, and social security, as well as human wellbeing and quality of life. Olfactory interventions, due to their low interference, are considered promising strategies for mitigating fatigue and reducing occupational health hazards.

Objective

The objective of this review is to bridge the current gaps in the literature by conducting a scoping review of olfactory interventions on human alertness. It aims to explore their application in various occupational settings and to provide comprehensive and practical guidance for the practical application of olfactory interventions in mitigating fatigue and reducing occupational risks.

Methods

The literature research was conducted in English using electronic databases such as Web of Science. Keywords related to scent and fatigue and the review followed PRISMA Extension for Scoping Reviews and PICO framework.

Results

28 studies were included in this work. Participant characteristics, fatigue measurement methods, and scent intervention methods, such as types of scents, intervention strategies, and scent presentation systems, are thoroughly investigated and discussed. Additionally, the study places a specific emphasis on the applications and research within the field of scent interventions for fatigue driving. Olfactory interventions have been applied to populations in various occupational fields, demonstrating beneficial effects on both physiological and psychological fatigue.

Conclusions

Olfactory intervention is effective and promising for enhancing alertness and improving the occupational environment. To provide detailed and practical guidance for the actual application of olfactory intervention in fatigue relief and reducing occupational health and safety hazards, further research into the potential mechanisms, applications, and efficacy assessment systems of fatigue-related olfactory interventions is necessary.

Massage Therapy as a Self-Management Strategy for Musculoskeletal Pain and Chronic Conditions: A Systematic Review of Feasibility and Scope

Background: Musculoskeletal pain and chronic conditions are associated with deteriorating pain, stress, anxiety, and health-related quality of life (HR-QOL). There is emerging evidence that performing massage therapy as self-management (MTSM) is a viable approach to alleviate these symptoms across various clinical populations. However, a significant gap remains on the effectiveness and limitation of MTSM usage as no systematic review has been conducted to comprehensively evaluate and synthesize the scope, feasibility, and efficacy of MTSM. This systematic review aimed to investigate the effect of MTSM on common symptoms of musculoskeletal and chronic conditions, followed by identifying characteristics of MTSM dosage, setting, and adherence for formulating themes. Methods: A systematic review was carried out using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, which involved searching seven electronic databases, including Medline (OVID), CINAHL (EBSCO), PEDro, Web of Science (Clarivate), PsycINFO (EBSCO), Google Scholar, and EMBASE (Elsevier) from inception to January 2023. Clinical studies were eligible if they included MTSM, and massage treatment was more than 50% of the intervention. The quality of studies was assessed using the Effective Public Health Practice Project Quality Assessment Tool. Target variables were extracted, including study design, participants' characteristics, outcome measures, massage dosage (duration, frequency, and timing), training setting, provider of massage training, adherence to the MTSM intervention, comparator, and key findings. Results: A total of 17 studies were evaluated and included 770 participants (female: N = 606) with musculoskeletal pain or chronic conditions. The emerged themes for MTSM utilization consisted of arthritis pain (knee, n = 3; neck, n = 1, hand, n = 2), neck and back pain (n = 4), and stress and anxiety (n = 3). Prescribed self-administered massage duration ranged from a single session to a maximum of 8-12 weeks, where 4 weeks (n = 8) was the most commonly prescribed duration. Out of 11 studies that used MTSM as a solo modality, 7 studies (41.2%) showed significant improvement in the outcome measures such as chronic neck and back pain, stress or anxiety, fatigue, quality of sleep, and HR-QOL. In addition, health benefits, including anxiety, depression, pain intensity, and pain threshold, were observed in six studies (35.3%) where MTSM was applied as a coadjuvant modality, which was combined with therapist-applied massage and physiotherapy. Conclusions: These findings support that MTSM is a viable approach to enhance the benefit of therapist-applied massage or as a solo modality for symptom management of musculoskeletal pain and chronic conditions. The review provides suggestions for design improvement, such as reporting participants' adherence to the prescribed massage regimen, that would be informative for providing a robust understanding of the magnitude or the extent to which MTSM is effective. Future studies on MTSM intervention are encouraged to use a theoretical framework and validated measures for determining and facilitating treatment fidelity.

How Are You Sleeping? Why Nutrition Professionals Should Ask Their Patients About Sleep Habits

Current literature has identified relationships among sleep, nutrition, and diet-related chronic diseases; however, knowledge about how sleep influences diet-related diseases is lacking in dietetics practice. This narrative review briefly explains sleep physiology and outlines the relationships between sleep duration and quality and common nutrition-related diseases, including obesity, diabetes, cardiovascular disease, obstructive sleep apnea, and cancer. Additionally, the review discusses how sleep influences wound healing and pregnancy outcomes and why hospitalized patients are likely to experience sleep problems. Plausible mechanisms explaining the relationships between sleep and disease are presented. Finally, commonly used sleep assessment tools and interventions are reviewed. Given the importance of sleep to health, dietitians should not only be aware of the role sleep plays in disease development and prevention but also assess sleep when feasible and refer patients and clients who are at high risk for sleep problems to a sleep clinic or community program that can address sleep issues.Teaching points:Sleep duration and quality influence risk and outcomes of common nutrition-related diseases.Sleep health evaluation is a missing piece in dietetic practice.There are easy-to-use, validated tools that dietitians can use to screen for sleep problems in order to refer patients and clients to sleep experts.

[Fatigue relief by aromatherapy use in prenatal and postnatal women: a systematic review and meta-analysis]

Purpose

The purpose of this systematic review was to examine aromatherapy interventions for prenatal and postnatal women, and to determine the effectiveness of these interventions on fatigue.

Methods

Six national and international databases were reviewed to retrieve and collect studies published up to September 7, 2021, describing randomized controlled trials and controlled clinical trials of aromatherapy interventions for prenatal and postnatal women's fatigue. Of the 323 articles initially identified, 64 duplicates were excluded and 259 were screened. After further excluding 216 articles not related to PICO framework, 10 were selected for review. Two reviewers independently selected studies and conducted data extraction and quality appraisal using Cochran's Risk of Bias and Risk of Bias Assessment Tool for Non-randomized Studies.

Results

The quality of the 10 selected studies was overall satisfactory. A meta-analysis of three studies showed that aromatherapy with lavender oil? produced a 0.75-point reduction in postnatal mothers' fatigue when compared to control groups. Sleep quality was also analyzed as a secondary outcome of fatigue. A meta-analysis of four studies using lavender and/or orange peel oil found that aromatherapy produced a 0.98-point improvement in postnatal mothers' quality of sleep. Although a meta-analysis could not be conducted to synthesize the findings for fatigue in pregnant women, inhalation and massage therapy using lavender oil showed positive effects on prenatal fatigue and sleep quality.

Conclusion

Aromatherapy using lavender oil and orange peel oil is effective in improving prenatal and postnatal fatigue and sleep quality.

Effectiveness of Aromatherapy on Ameliorating Fatigue in Adults: A Meta-Analysis

Background

Fatigue is a common symptom in adults that may cause physical and psychological problems and reduce quality of life. Aromatherapy could possibly provide relief for those suffering from fatigue. Here, we evaluated the effect of aromatherapy on fatigue in adults.

Methods

We searched the PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, Chinese Biomedical Literature, SinoMed, Wanfang, and Chinese Scientific Journal Database databases for randomized controlled trials of aromatherapy treatment for fatigue in adults from their inception to June 2021. Two reviewers searched independently, extracted the characteristics of the studies, and assessed the risk of bias using the Cochrane risk-of-bias tool and Stata v. 14.0.

Results

Nineteen studies were included in this systematic review. Aromatherapy had a significant effect on fatigue (standardized mean difference −0.64, 95% confidence interval−1.14, −0.15, I² 94.4%, P < 0.001). Subgroup analysis according to aromatic type, substance, frequency, treatment duration, intervention, outcomes measurement, and population type showed that aromatherapy had a significantly greater effect in the intervention group, compared to the control group. Funnel plots and Egger's test indicated no significant publication bias.

Conclusion

Our results suggest that aromatherapy ameliorates fatigue in adults who suffer from chronic diseases. A rigorous intervention program and larger randomized controlled trials are needed.

A critical review on clinical evidence of the efficacy of lavender in sleep disorders

Sleep disorders are one of the most prevalent psychiatric diseases. Insomnia is the most common sleep disorder amongst the general population. It is also one of the most frequent complaints in primary healthcare centers. Lavender is called "the broom of the brain" in different oriental traditional medicines. It is one of the most used plants for patients with sleep disorders. This study reviews what is currently known about the use of lavender for sleep disorders in patients with different diseases, from cancers and end-stage renal disease to neurological-psychiatric diseases (e.g., depression, dementia, and autism), respiratory, cardiac, and metabolic diseases. Additionally, its most used administration route is the inhalation of its essential oil (i.e., aromatherapy) alone or in combination by massage. Some limitations of the reviewed literature were discussed briefly. Overall, this critical review provides promising evidence of the lavender efficacy for sleep disorders in a wide variety of populations and diseases. However, further clinical studies with robust design and longer durations of intervention are necessary for more evidence-based judgment on its effect on sleep problems and to investigate its mechanism of action.

The Effect of Coffee Aromatherapy on Reducing Fatigue and Stress Levels of Female Caregivers Caring for the Elderly in Hospitals

Background. The exploration of coffee as an aromatherapy in the health service has not been widely carried out. In many cases, aromatherapy has been shown to reduce stress and fatigue. Purpose.   To analyzes the effect of coffee aromatherapy on the fatigue and stress levels of female caregivers caring for the elderly at the University of Sumatera Utara Hospital (USU Hospital), in Medan. Methods. This is a quasi-experiment one group pretest posttest design.  The research involved 16 caregivers were given a treatment of coffee oil by inhalation for 15 minutes for three consecutive days, without coffee oil inhalation and 10% of coffee oil concentration on the first day, 20% on the second day, and 30% on the third day. Each sample received a pretest and posttest in the form of stress and fatigue instruments.  The data analysis performed was univariate in order to describe the properties of each variable examined and analyze the mean score. Similarly, bivariate analysis with the Analysis of Variance (ANOVA) statistical test was used to determine the effect of coffee aromatherapy on reducing the fatigue and stress level. Results. The result showed that most caregivers were elderly children with an average age of 38 years, 81.3% assisted in caring for the elderly, and actively working outside the home. Based on the ANOVA test, the data showed that the administration of coffee aromatherapy for three consecutive days has no effect on female caregivers’ fatigue and stress level.  However, the mean score showed a decrease in fatique and stress level before and after coffee oil inhalation in three days.  Conclusion. It is necessary to provide coffee oil aromatherapy intervention with a longer duration to have an effect on reducing caregiver fatique and stress in the future, so the results are expected to form the basic data for the design of nursing interventions based on complementary therapies in order to reduce the fatigue and stress of caregivers while providing care to the hospitalized elderly.

Comparing the Effect of Aromatherapy with Peppermint and Lavender Essential Oils on Fatigue of Cardiac Patients: A Randomized Controlled Trial

Methods

This randomized controlled clinical trial was conducted on 105 cardiac patients. They were randomly divided into three groups: peppermint essential oil (n = 35), lavender essential oil (n = 35), and control (n = 35). Fatigue Severity Scale (FSS) was used to collect data. The intervention was performed for 7 nights. Before and after the intervention, the questionnaire was completed by all patients. In each intervention group, patients inhaled 3 drops of lavender or peppermint essential oils. In the control group, patients inhaled 3 drops of aromatic placebo.

Results

The results showed the average fatigue decreased in the study groups. There was no statistically significant difference between the two groups of lavender and peppermint in terms of mean fatigue after the intervention. However, there was a statistically significant difference between lavender and control groups (P < 0.001), as well as peppermint and control groups (P < 0.001).

Conclusion

Aromatherapy with peppermint and lavender essential oils can reduce the fatigue of cardiac patients, so the use of these fragrances is recommended.

Medicinal Plants for Insomnia Related to Anxiety: An Updated Review

Sleep disorders are common among the general population and can generate health problems such as insomnia and anxiety. In addition to standard drugs and psychological interventions, there are different complementary plant-based therapies used to treat insomnia and anxiety. This review aimed to find and examine the most recent research on the use of herbal medicines for treating anxiety and insomnia as compiled from clinical trials, as well as to assess the safety and efficacy of these medicines and to elucidate their possible mechanisms of action. The process entailed a search of PubMed, Scopus, and the Cochrane Library databases from 2010 to 2020. The search terms included "sleep disorder", "insomnia", "sedative", "hypnotic", "anxiety", "anxiolytic", and "clinical trial", combined with the search terms "herbs" and "medicinal plants", in addition to individual herbal medicines by both their common and scientific names. This updated review, which focuses mainly on clinical trials, includes research on 23 medicinal plants and their combinations. Essential oils and their associations have also been reviewed. The efficacy of medicinal plants depends on treatment duration, types of study subjects, administration route, and treatment method. More clinical trials with an adequate, standardized design are necessary, as are more preclinical studies to continue studying the mechanisms of action. As a result of our work, we can conclude that the 3 plants with the most potential are valerian, passionflower, and ashwagandha, with the combination of valerian with hops and passionflower giving the best results in the clinical tests.

Effect of aromatherapy on sleep quality of adults and elderly people: A systematic literature review and meta-analysis

PURPOSE

The purpose of this study was to characterize studies on aromatherapy and sleep quality and to identify the measurable effects of aromatherapy on the sleep quality of adults and elderly people.

METHODS

We searched eight electronic databases for relevant studies published between January 2011 and December 2019 using the medical subheadings, "adult or elderly," "aromatherapy or aroma intervention," and "sleep quality or sleep satisfaction." Statistical analyses of the combined effect sizes, homogeneity, heterogeneity, and trim-and-fill method were performed using MIX 2.0 Pro.

RESULTS

Based on the combined results of the 30 included studies, the overall effect size of sleep quality was 0.74, which was statistically significant. A subgroup analysis was performed to assess the overall improvement in sleep quality based on country, study design, and type of intervention: the effect size of aromatherapy in East Asia, quasi-experimental studies, and aroma massage therapy studies was 1.02, 1.24, and 1.30, respectively, with higher sleep quality in each subgroup. The effect size was 0.86 and 0.80 for ≤12 interventions and for an intervention period of ≤4 weeks, respectively. Aromatherapy interventions lasting >20 min per session had an effect size of 1.28, with no significant difference in sleep quality. Quality evaluation revealed that the sleep quality after aromatherapy was significantly high in studies with methodological quality scores >8, with an effect size of 0.93. Moreover, significant combined effects of aromatherapy were observed with other variables such as stress, pain, anxiety, depression, and fatigue.

CONCLUSION

Aromatherapy improves sleep quality and reduces stress, pain, anxiety, depression, and fatigue in adults and elderly people.

Individual differences in personality predict the use and perceived effectiveness of essential oils

Essential oil (EO) use is growing in popularity and ostensibly used for treating or preventing various ailments or conditions. Despite the increase in use, there is a paucity of research on psychosocial predictors of EO use and their perceived effectiveness. However, several psychosocial characteristics are associated with health-promoting behavior and a tendency to believe in homeopathic cures. In the current study, we examined a variety of individual differences in the use and perceived effectiveness of essential oils in a sample of 1,202 participants (Mage = 31.33, SD = 13.77; 61.7% women, 75.6% Caucasian). We found that receptivity to pseudo-profound fabricated statements and religiosity were the most consistent predictors of greater use of, perceived effectiveness of, and a willingness to spend more money on EOs.
