“…When inhaled, lavender stimulates the olfactory bulb of the brain and transmits signals to the limbic system, a sensory center that secretes enkephalin, endorphins, and serotonin. It is believed that lavender aromatherapy may reduce stress by reducing the activity of the sympathetic nervous system and increasing activity in the parasympathetic nervous system, which creates a sense of relaxation [ 3 , 20 , 43 ]. The aromatherapy administration method has also been shown to have almost immediate benefits, with significant reductions in anxiety following the first treatment [ 4 ].…”

“…There are four species of this Mediterranean evergreen perennial plant, but the one most commonly used for therapeutic purposes is Lavandula angustifolia [ 2 ]. This particular species has been found to be more effective at reducing stress in comparison to other lavender species, such as L. stoechas [ 3 ]. Lavender has a long history of medicinal use, cited often in Roman literature, such as “De Materia Medica” by Dioscorides from the 16th century [ 2 ].…”

Lavender administration in humans has been shown to promote calmness without the side effects often observed with benzodiazepines. Studies in both humans and rodents have found that ingestion of oral lavender capsules resulted in significantly decreased anxiety. Additionally, mice developed an anti-conflict effect and humans increased socially inclusive behaviors. Given the safety of oral lavender oil and the observed benefits, we administered daily lavender capsules to six chimpanzees who exhibited conflict-instigating behaviors in an effort to further decrease our already low levels of wounding. We compared the total number of wounds in 25 chimpanzees housed with the six lavender-treated chimpanzees in five different social groups (1) prior to administration of daily oral lavender capsules to (2) total wounds during daily oral lavender capsule treatment. We hypothesized that lavender therapy treatment would reduce overall wounding in the social groups. Surprisingly, overall wounding was higher during the lavender treatment period (p = 0.01), yet the percentage of wounds requiring treatment significantly decreased during the lavender therapy period (36% vs. 21%, p = 0.02).

“…For RCTs, a score of 0–13 was possible, while for quasi‐experimental studies, the score ranged from 0 to 9. RCTs with a score of 1–4 were considered low quality, 5–8 were medium quality and 9–13 were high quality (Ghavami et al., 2022). At the same time, for quasi‐experimental studies, a score of 14 was considered low, 5–7 moderate and 8–9 was high quality (Mansoor & Khuwaja, 2020).…”

PurposeMindfulness‐based interventions (MBIs) are well‐validated interventions to enhance the favourable body image of individuals. Despite their wide application, the efficacy of MBIs in reducing body image dissatisfaction (BID) among various clinical populations remains unclear. This study aims to expand the literature on MBIs for BID and identify effective types of MBIs for reducing BID in diverse clinical populations for future research and practice.MethodsA systematic search for studies published in English on the effectiveness of MBIs for BID among the clinical population was done on APA PsycNet, PubMed, Science Direct, Web of Science and Google Scholar databases in August 2023. Of the 1962 articles initially identified, 17 were found eligible and evaluated based on the JBI checklist.ResultsRandom effects meta‐analyses on six MBIs revealed their effectiveness in reducing BID among the clinical population (SMD = −.59 and 95% CI = −1.03 to −.15, p = .009), with Acceptance and Commitment Therapy (ACT) (SMD = −1.29, 95% CI = −2.06 to −.52, p = .001) and My Changed Body (MyCB) (SMD = −.24, 95% CI = −.46 to −.01, p = .04) reporting significant effect sizes. Among the patients with breast cancer, MyCB (SMD = −.24, 95% CI = −.46 to −.01, p = .04) showed a significant effect size.ConclusionsMBIs appear to be promising interventions in reducing BID among the clinical population. However, findings should be considered cautiously due to the possible publication bias, high heterogeneity and fewer available studies.

“…The total score range based on the number of "yes" is between 0 and 13. A score of 1-4 was considered "low quality, " a score of 5-8 was considered "medium quality, " and a score of 9-13 was considered "high quality" [20]. Two researchers (F. R. and M. K.) independently analyzed each criterion of the JBI.…”

Background Polycystic ovary syndrome (PCOS) is considered as the most common endocrinopathy among women of childbearing age and the most important cause of anovulatory infertility. The present study aimed to estimate the pooled effect of exercise on anti-Mullerian hormone (AMH) levels in PCOS women using systematic review and meta-analysis. Main body The present study was conducted according to the PRISMA guidelines from 2011 to October 2021. All published studies, which met the inclusion criteria, were searched in SID, MagIran, Embase, PubMed, Scopus, Web of Science (WoS) databases, and Google Scholar motor engine using related MeSH/Emtree terms, which were combined with free text word. Finally, 12 articles were included in the meta-analysis. As a result of the combination of the studies, after exercise, AMH level in the intervention group significantly decreased up to 0.517 ± 0.169 more than that in the control group (P ˂ 0.05). The results of subgroup analysis demonstrated that the effect of resistance training for 16 weeks was higher on women with body mass index (BMI) (≥ 25 kg/m2) and AMH (≥ 10 ng/mL) before the intervention. GRADEpro software was used to grade the level of evidence. Conclusion This systematic review and meta-analysis showed that either strength exercise or aerobic exercise decrease the AMH level in PCOS women. It seems more duration of the exercise has a more potential advantage to reduce the AMH levels in women with PCOS. Although the results graded by very low-quality evidence, it is recommended to include exercise in the treatment programs of PCOS patients.
