Yogic Sleep and Walking Protocol Induced Improvement in Sleep and Wellbeing in Post-menopausal Subject: A Longitudinal Case Study During COVID Lockdown

Functional connectivity changes in meditators and novices during yoga nidra practice

Yoga nidra (YN) practice aims to induce a deeply relaxed state akin to sleep while maintaining heightened awareness. Despite the growing interest in its clinical applications, a comprehensive understanding of the underlying neural correlates of the practice of YN remains largely unexplored. In this fMRI investigation, we aim to discover the differences between wakeful resting states and states attained during YN practice. The study included individuals experienced in meditation and/or yogic practices, referred to as 'meditators' (n = 30), and novice controls (n = 31). The GLM analysis, based on audio instructions, demonstrated activation related to auditory cues without concurrent default mode network (DMN) deactivation. DMN seed based functional connectivity (FC) analysis revealed significant reductions in connectivity among meditators during YN as compared to controls. We did not find differences between the two groups during the pre and post resting state scans. Moreover, when DMN-FC was compared between the YN state and resting state, meditators showed distinct decoupling, whereas controls showed increased DMN-FC. Finally, participants exhibit a remarkable correlation between reduced DMN connectivity during YN and self-reported hours of cumulative meditation and yoga practice. Together, these results suggest a unique neural modulation of the DMN in meditators during YN which results in being restful yet aware, aligned with their subjective experience of the practice. The study deepens our understanding of the neural mechanisms of YN, revealing distinct DMN connectivity decoupling in meditators and its relationship with meditation and yoga experience. These findings have interdisciplinary implications for neuroscience, psychology, and yogic disciplines.

Mind-Stuff and Withdrawal of the Senses: Toward an Interpretation of Pratyahara in Contemporary Postural Yoga

Yoga has become a popular health and wellbeing practice that draws on ancient philosophy. Pratyahara is a core tenet of yoga practice and is often translated to mean withdrawal of the senses. Withdrawing from the senses plays a key role in aiding yoga practitioners to find spiritual enlightenment by transcending the worldly. Withdrawing from the material world, however, does not neatly fit within the parameters of the contemporary postural yoga industry. This paper looks at the conceptual origins of pratyahara through stances relevant to health research. The author weaves biomedical, esthetic, and neoliberal onto-epistemological stances through health discourse to discuss how postural yoga both resists and replicates power imbalances. In so doing the author emphasizes the paradoxical nature of pratyahara as it is reflected in socio-political tensions of the yoga industry. To conclude, the author suggests that pratyahara itself can be useful in resolving this tension as yoga fulfills a philosophical prerogative for social change.

Yoga Nidra, a Nonpharmacological Technique in Management of Insomnia and Overall Health in Postmenopausal Women

Yoga Nidra is a promising technique through which body is consciously simulated into a profound relaxation state similar to attained during naturally occurring deep sleep. It is aimed to attain complete emotional, physical, and mental relaxation of body and mind. In postmenopausal phase of life, regular practice of Yoga Nidra at home preferably in morning, can help in reduction in anxiety and pain associated with early morning awakenings. This nonpharmacological technique has a therapeutic potential to improve sleep quality and quantity, and overall well-being.

Impacts of COVID-19 Pandemic on Sleep Quality Evaluated by Wrist Actigraphy: A Systematic Review

COVID-19 has probably contributed as a risk factor for sleep disturbance. Actigraphy has been used to evaluate sleep complaints in self-isolated populations and frontline doctors during the COVID-19 pandemic. This systematic review aims to summarize the impact of the COVID-19 pandemic on sleep through wrist actigraphy, estimating sleep latency, total sleep time, awakening-after-sleep onset, and sleep efficiency. Searches were conducted of observational studies on the PubMed, Embase, Scopus, Web of Science, and PEDro databases from 1 December 2019 to 31 December 2022. Ninety articles were found, and given the eligibility criteria, fifteen were selected. Six studies were classified by the National Health and Medical Research Council as evidence level IV, two studies as level III-3, and seven studies as level III-2. According to the ACROBAT-NRSI instrument, three studies were classified as having a "serious" risk of bias, two as having "critical" risk, four as having "moderate" risk, and six as having "low" risk. In the selected publications, various populations were evaluated via actigraphy during the COVID-19 pandemic, with reports of "poor" sleep quality. Actigraphy may be a relevant tool to assess individual day-night rhythms and provide recommendations under enduring pandemic conditions. Moreover, as actigraphy presents objective data for sleep evaluations, it is suggested that this method be used in similar pandemics and that actigraphy be included as part of the sleep hygiene strategy.

The Updating and Individualizing of Sleep Hygiene Rules for Non-clinical Adult Populations

Sleep hygiene is essential for the prevention of somatic and mental disorders, including the prevention of sleep disorders. However, it does not typically address individual differences. The aim of this review is threefold: first, to outline the empirical evidence for particular components of sleep hygiene rules; second, to indicate the importance of individualized sleep hygiene application with regard to the varying degree of validity of sleep hygiene rules in the population; third, to highlight a new field of sleep hygiene, namely light hygiene. PubMed and Google Scholar were used to identify studies that were published between 2007 and 2022. A search was conducted for studies related to sleeping rules topics: sleep regularity, regular exercise, alcohol, caffeine, napping, relaxation and meditation, food intake and light exposure. In applying these sleep hygiene principles, it is essential to pay attention to individual variables such as age, genetic predisposition, health status, and substance (caffeine, alcohol) possible dependence.

Effects of aerobics training on anxiety, depression and sleep quality in perimenopausal women

OBJECTIVE

To investigate the effect of aerobics training on anxiety, depression and sleep disturbance in perimenopausal women.

MATERIALS AND METHODS

A total of 289 perimenopausal women with anxiety, depression or sleep disorder in Lishi district of Luliang city were treated with aerobics training. Self-rating anxiety scale, self-rating depression scale and Pittsburgh sleep scale were used to investigate the anxiety, depression and sleep status of perimenopausal women before and after intervention.

RESULTS

After aerobics training, the scores of self-rating anxiety scale, self-rating depression scale and Pittsburgh sleep questionnaire were 48.26 ± 6.47, 50.27 ± 6.54 and 10.64 ± 4.38, respectively. The levels of anxiety, depression and sleep disorder in 289 subjects were significantly lower than those before intervention (t = 3.865, 4.541, 5.596, P < 0.01). The remission rate of symptoms was significantly different in subjects with different frequency of spontaneous practice (P < 0.01), and the higher the number of spontaneous practice, the higher the remission rate of anxiety, depression and sleep disorders in subjects (P < 0.01).

CONCLUSION

aerobics training can effectively improve the anxiety and depression of perimenopausal women, improve sleep quality, the more frequency of practice, the more obvious the effect. It can be used as an intervention to improve the mental health level of perimenopausal women in terms of anxiety, depression and sleep quality in clinical promotion.
