Promoting mental health and wellbeing in schools: the impact of yoga on young people's relaxation and stress levels.

This study aimed to examine students' experiences with yoga interventions in school. The findings revealed that practicing yoga made young people more aware of their need to relax and positively impacted their mental health and wellbeing. We explored the emphasis on relaxation among our study participants and how relaxation is related to other aspects, such as their experience of stress and sleep habits. This article is based on qualitative data gathered from teenagers in Norway who participated in the Norwegian part of the European research project "Hippocampus: Promoting Mental Health and Wellbeing among Young People through Yoga." The project introduced yoga to young people in schools with an emphasis on those who were disadvantaged, including those with mental health issues and other challenges related to their background. Data were collected from nine individual, semi-structured interviews and 133 logs collected in the spring of 2019. The major themes identified through the interviews and log material included becoming more relaxed and aware of the need to unwind. Thus, the focus on relaxation is based on the importance of the participants assigned to this theme. The study results suggest that yoga enhanced the students' awareness and skills and empowered them to make healthier lifestyle choices. We viewed the importance of relaxation from a salutogenic perspective, focusing on the factors that contribute to good health in contrast to a pathogenic perspective, where curing diseases is the goal.

"I Just Find It Easier to Let Go of Anger": Reflections on the Ways in Which Yoga Influences How Young People Manage Their Emotions.

In this article we discuss how young people experienced a school-based yoga intervention. We pay particular attention to how yoga provides a space for young people to deal with their emotions. We base our discussion on qualitative data from young people in Norway who participated in the European research project "Hippocampus: Promoting Mental Health and Wellbeing among Young People through Yoga." The qualitative results are based on experiences described by these young people in individual semi-structured interviews and in diaries or logs. Our data include nine interviews performed in the spring of 2019 with young people of Norwegian and refugee background in their late teens and early twenties. There were also 133 logs noted by the students exposed to the yoga intervention. In the qualitative interviews, young people talk about yoga and emotional management, improved sleep habits, and regulation. They also report improved ability to regulate and cope with stress. Yoga seemed especially beneficial for refugee trauma. In this article, we have chosen to focus on the utterances of young people about emotions, as those were quite dominant in our data, especially in the interview material. We have identified instances of emotional regulation, but also of emotional processes and changes of emotions, all of which were related to these young students practicing yoga. The impact of yoga on emotions illustrates the potential of yoga to improve the well-being and mental health of young people.

Global Perspectives on Children's Digital Opportunities: An Emerging Research and Policy Agenda.

Diverse international perspectives show that children can benefit greatly from digital opportunities. Despite widespread optimism about the potential of digital technologies, especially for information and education, the research reveals an insufficient evidence base to guide policy and practice across all continents of the world, especially in middle- and low-income countries. Beyond revealing pressing and sizeable gaps in knowledge, this cross-national review also reveals the importance of understanding local values and practices regarding the use of technologies. This leads us to stress that future researchers must take into account local contexts and existing inequalities and must share best practices internationally so that children can navigate the balance between risks and opportunities. This article documents the particular irony that while the world's poorer countries look to research to find ways to increase access and accelerate the fair distribution of digital educational resources, the world's wealthier countries look to research for guidance in managing excessive screen time, heavily commercial content, and technologies that intrude on autonomy and privacy. We conclude by recommending that digital divides should be carefully bridged with contextual sensitivity to avoid exacerbating existing disparities; that the provision of technological resources is complemented by a focus on skills enhancement, for teachers as well as students; that a keen eye is needed to ensure the balance of children's protection and participation rights, with protection now including data abuses as well as safety considerations; and that we forge collaborations among all stakeholders in seeking to enhance children's digital opportunities worldwide.

Reducing stigma and discrimination to improve child health and survival in low- and middle-income countries: promising approaches and implications for future research.

The social processes of stigmatization and discrimination can have complex and devastating effects on the health and welfare of families and communities, and thus on the environments in which children live and grow. The authors conducted a literature review to identify interventions for reducing the stigma and discrimination that impede child health and well-being in low- and middle-income countries, with a focus on nutrition, HIV/AIDS, neonatal survival and infant health, and early child development. Despite broad consensus on the importance of stigma and discrimination as barriers to access and uptake of health information and services, the authors found a dearth of research and program evaluations directly assessing effective interventions in the area of child health except in the area of reducing HIV-related stigma and discrimination. While the literature demonstrates that poverty and social exclusion are often stigma-laden and impede adult access to health information and services, and to education relevant to family planning, child rearing, nutrition, health promotion, and disease prevention, the child health literature does not document direct connections between these known mediators of child health and the stigmatization of either children or their caregivers. The child health field would greatly benefit from more research to understand and address stigma as it relates to child health and well-being. The authors suggest applying a framework, adapted from the HIV stigma field, to direct future research and the adaptation of existing strategies to reduce HIV-related stigma and discrimination to address social and health-related stigmas affecting children and their families.

Yoga for Children and Young People's Mental Health and Well-Being: Research Review and Reflections on the Mental Health Potentials of Yoga.

This article discusses yoga as a potential tool for children to deal with stress and regulate themselves. Yoga provides training of mind and body to bring emotional balance. We argue that children and young people need such tools to listen inward to their bodies, feelings, and ideas. Yoga may assist them in developing in sound ways, to strengthen themselves, and be contributing social beings. First, we address how children and young people in today's world face numerous expectations and constant stimulation through the Internet and other media and communication technologies. One reason why children experience stress and mental health challenges is that globalization exposes the youth all over the world to various new demands, standards, and options. There is also increased pressure to succeed in school, partly due to increased competition but also a diverse range of options available for young people in contemporary times than in the past. Our argument also partially rests on the fact that modern society offers plenty of distractions and unwelcome attractions, especially linked to new media technologies. The dominant presence of multimedia devices and the time spent on them by children are clear indicators of the shift in lifestyles and priorities of our new generation. While these media technologies are valuable resources in children and young people's lives for communication, learning, and entertainment, they also result in constant competition for youngster's attention. A main concept in our article is that yoga may help children and young people cope with stress and thus, contribute positively to balance in life, well-being, and mental health. We present research literature suggesting that yoga improves children's physical and mental well-being. Similarly, yoga in schools helps students improve resilience, mood, and self-regulation skills pertaining to emotions and stress.

Amygdalar neuronal responses to peripheral nociceptive stimuli in rats.

Amygdala plays a very important role in the mediation of pain. In the present study the behaviour of the amygdalar neurons in response to various peripheral noxious stimuli was observed. Noxious mechanical, thermal, electrical, chemical and the non-noxious stimuli (touch) were applied individually to the animal and then the neuronal responses to these stimuli were recorded. Our results showed that the majority of amygdalar units recorded from medial, lateral and basolateral nuclei, responded to different peripheral noxious (thermal, electrical, chemical mechanical) and non-noxious stimuli by excitation. However few neurons decreased their activity on stimulation. Some of these neurons also exhibited after discharge following application of higher intensity of noxious stimuli.

Cardiovascular Responses to Tonic Pain in REM Sleep-Deprived Rats: Role of Melatonin and Beta Endorphin.

OBJECTIVE: Chronic pain is associated with increased incidence of hypertension. Sleep deprivation, common in patients with chronic pain, is associated with increased blood pressure and heart rate. This study was designed to determine whether sleep deprivation induces increased cardiovascular responses to pain. In addition; we examined the role of melatonin and endorphins in mediating these responses. METHOD: The study was conducted in Sprague-Dawely rats divided into a control group (n=8) and Rapid Eye Moment sleep deprived (REMSD) group (n=8). REM sleep deprivation was done for three days using the inverted flowerpot technique. Systolic BP and HR were recorded at baseline as well as 5, 10 and 30 minutes after intra-plantar formalin injection. In addition, serum melatonin and endorphin levels were determined. RESULTS: Under basal conditions, BP and HR and following acute pain (1(st) phase of formalin injection) were comparable with non-sleep deprived (non-SD) state. In contrast, the REMSD rats showed significantly greater increases in HR and BP during the 2(nd) phase of formalin pain as compared to non-SD state. These changes were associated with significant reductions in serum melatonin and endorphin levels in REMSD rats. CONCLUSION: These data indicate that exaggerated blood pressure and HR responsiveness to pain in sleep deprivation could be mediated through reductions in melatonin and endorphin.

Interactions between leptin, neuropeptide-Y and insulin with chronic diurnal fasting during Ramadan.

BACKGROUND: Fasting during the month of Ramadan for Muslims is a unique metabolic model that includes abstinence from food and fluid intake during the period from dawn to sunset as well as a reduction in meal frequency and alterations in the sleep-wakefulness cycle. Leptin, neuropeptide-Y and insulin are thought to play an important role in long-term regulation of caloric intake and energy expenditure. However, the long-term changes and interactions between these factors during this pattern of fasting are not known. SUBJECTS AND METHODS: The study was conducted on 46 healthy female volunteers (age, 22+/-2 years; BMI, 25.3+/-0.7 kg/m2). Anthropometrical measurements, estimation of body fat and fasting serum levels of neuropeptide Y, leptin, insulin and glucose were estimated at baseline (day 1), days 14 and 28 of the month of Ramadan and 2 weeks after Ramadan. RESULTS: Baseline serum levels of leptin correlated positively with body fat (r=0.87, P=0.0002). Serum leptin levels exhibited a significant increase by approximately 41% and neuropeptide-Y levels were decreased by 30.4% throughout the month of Ramadan. In addition, a significant correlation (r=0.63, P=0.0001) was found between changes in serum leptin and serum insulin. However, changes in serum neuropeptide-Y levels did not correlate with those of leptin or insulin CONCLUSIONS: Long-term fasting with interrupted nocturnal eating is associated with significant elevations in serum leptin and insulin and reduction in serum neuropeptide-Y. The changes in serum leptin are likely mediated through insulin. However, changes in neuropeptide-Y appears to be mediated independently of leptin or insulin during this type of fasting

Serum leptin and insulin levels during chronic diurnal fasting.

Ramadan fasting is a unique model that is associated with restriction of the timing of food and fluid intake food from dawn to sunset and reduction in meal frequency and sleep duration. Leptin levels are thought to play a role in long-term regulation of caloric intake and fat deposition. However, the long-term changes in leptin levels during this pattern of fasting are not known. The study was conducted on lean (N=6, BMI=22.5+/-0.4) and obese (N=18, BMI=33.1+/-1.0) healthy female volunteers. Fasting serum levels of leptin, insulin and glucose were estimated at baseline (day 1), days 14 and 28 of the month of Ramadan and 2 weeks after Ramadan. Baseline serum levels of leptin were significantly higher in obese (13.5+/-1.96 microg/L,P<0.05) compared with lean subjects (9.60+/-0.80 microg/L) and correlated positively with body fat (r=0.82, P=0.0004). Serum leptin levels exhibited a significant and comparable increase by 39% and 37% throughout the month in lean and obese subjects, respectively. In addition, a significant correlation (r=0.52, P=0.003) was found between changes in serum leptin and serum insulin levels. We conclude that chronic diurnal fasting is associated with significant elevations in serum leptin. These elevations appear to be mediated by changes in serum levels of insulin. These data support the role of insulin in the long-term regulation of leptin secretion during chronic diurnal fasting followed by nocturnal eating during the month of Ramadan.

Recovery from lesion-associated learning deficits by fetal amygdala transplants.

Bilateral lesions of the amygdaloid complex result in elimination or attenuation of the conditioned freezing that is normally seen in the conditioned emotional response (CER) paradigm and the active avoidance (AA) task. We observed the effect of amygdalar tissue transplantation on the ability of lesioned (central nucleus of amygdala, CeA) rats to learn CER and AA. In two groups of adult Wistar rats, sham operation or bilateral lesions of the CeA were produced electrolytically (2mA for 8 sec). In a third group, fetal amygdalar tissue was transplanted at the CeA-lesioned site 2 d postoperatively. All rats were trained on CER and AA from the 6th postoperative day. In comparison with the sham-operated group, bilaterally CeA-lesioned rats showed a significant (p < 0.001) increase in all CER scores, indicating an acquisition deficit. After fetal amygdalar tissue transplantation, the CER scores significantly decreased (p < 0.05) when compared with the lesioned group. A significant (p < 0.01) decrease in the percentage of avoidance in the AA task occurring after CeA lesion returned to control values after amygdalar tissue transplantation. In conclusion, in CeA-lesioned rats a complete behavioral deficit in learning CER and AA was restored by transplanting fetal amygdalar tissue at the lesioned site.

The formalin test: a tonic pain model in the primate.

The formalin test has been used in monkeys for assessing pain. After formalin injection in the palmar surface of the hand just proximal to the base of the fingers, the monkey's responses are rated for 1 h according to objective behavioral criteria. The present 'tonic' pain model has a fair degree of objectivity, validity, reproducibility and quantifiability. The analgesic effects of morphine and pethidine have been evaluated.
