Objective The aim of this study is to evaluate the acute impact of breathing exercises based on yogic pranayama on cravings in abstaining smokers.Methods Participants visited the laboratory on two occasions 24 h apart and were asked to abstain from smoking12 h prior to the first visit until the end of the second visit. Smokers (N096) were randomly allocated to a yogic breathing exercise (YBG) or video control (VCG) group. The former was instructed on breathing exercises, practised these for 10 min and asked to use these when experiencing cravings until the next visit. The latter was shown a breathing exercise video for 10 min and asked to concentrate on their breathing. Strength of urges to smoke, other craving measures and mood and physical symptoms associated with cigarette withdrawal were assessed at the beginning and end of the first visit, and again at the second visit. Results At immediate follow-up, in the laboratory, all craving measures were reduced in YBG compared with VCG (strength of urges: F(1, 96)016.1, p<0.001; cigarette craving: F(1, 96)0 11.3, p00.001; desire to smoke: F(1, 96)06.6, p00.012). There was no effect on mood or physical symptoms. Adherence to the breathing exercise regimen in the following 24 h was low, and at 24 h follow-up, there was no evidence of reduced cravings in YBG compared with VCG. Conclusions Simple yogic-style breathing exercises can reduce cigarette craving acutely in the laboratory. Further

Is all yoga good for anxiety?This is a good question, and most likely it comes from her own experience that some types of yoga causes her to become more restless and some styles of yoga are more calming. I find turning to Ayurvedic Medicine can be a powerful way to find the answers to the question. According to Ayurvedic Medicine, anxiety is a sign of vata being in excess. People with a predominantly vata dosha tend to be incredibly creative, always on the go, their energy comes in bursts and they are prone to fatigue. Vatas have thin frames, dry skin and hair and cold hands and feet. Ayurvedic Medicine works on the philosophy that like increases like. So when vata goes into excess and you start to experience anxiety, it is a symptom of too much air, too much thinking, too much movement, too much in your head. This is no big deal, it is not a problem. It is simply a matter of bringing this imbalance back into balance. So you can imagine if experience has moved up into your head with worry, stress, your mind has sped up - you need practices that are calming, grounding, nourishing, slow to find balance. Vata is the most exquisitely sensitive dosha, so you need to take great care and gentleness. In my opinion, yoga styles like power yoga, vinyasa flow, ashtanga yoga, kundalini yoga, bikram yoga and hot yoga can leave delicate people that are predominantly vata feeling further exhausted, ungrounded, and stressed out. For anxiety, I would recommend practices such as yin yoga and restorative yoga. Both these styles have long holds and are incredibly grounding because they are practiced on the floor, and in the case of restorative yoga with many props. I would also recommend practices like yoga nidra which can help to release the anxiety and worry. The focused attention of bringing your awareness back into your body can help to change your neural pathways and release anxiety at its root. So today I have a gift for you, 7 days of the best and most appropriate yoga to relieve anxiety: If you made it all the way to the end give yourself a thumbs up and put, I am balancing vata dosha in the comments. Thanks for watching, Namaste, Melissa

Hamilton’s theory of inclusive fitness showed how natural selection could lead to behaviors that decrease the relative fitness of the actor and also either benefit (altruism) or harm (spite) other individuals. However, several fundamental issues in the evolution of altruism and spite have remained contentious. Here, we show how recent work has resolved three key debates, helping clarify how Hamilton’s theoretical overview links to real-world examples, in organisms ranging from bacteria to humans: Is the evolution of extreme altruism, represented by the sterile workers of social insects, driven by genetics or ecology? Does spite really exist in nature? And, can altruism be favored between individuals who are not close kin but share a “greenbeard” gene for altruism?

<p>Interest in mindfulness-based interventions for children and adolescents is burgeoning, bringing with it the need for validated instruments to assess mindfulness in youths. The present studies were designed to validate among adolescents a measure of mindfulness previously validated for adults (e.g., Brown &amp; Ryan, 2003), which we herein call the Mindful Attention Awareness Scale—Adolescent (MAAS–A). In 2 large samples of healthy 14- to 18-year-olds (N = 595), Study 1 supported a single-factor MAAS–A structure, along with acceptably high internal consistency, test–retest reliability, and both concurrent and incremental validity. In Study 2, with a sample of 102 psychiatric outpatient adolescents age 14–18 years, participants randomized to a mindfulness-based stress reduction intervention showed significant increases in MAAS–A scores from baseline to 3-month follow-up, relative to nonsignificant score changes among treatment-as-usual participants. Increases in MAAS–A scores among mindfulness-based stress reduction participants were significantly related to beneficial changes in numerous mental health indicators. The findings support the reliability and validity of the MAAS–A in normative and mixed psychiatric adolescent populations and suggest that the MAAS–A has utility in mindfulness intervention research.</p>

Mindfulness- and acceptance-based strategies effectively alter clients' relationships with their internal experiences, which may have been previously restricted, avoided, or even beyond clients' awareness. Even though the scientific exploration of the psychological benefits of mindfulness in the treatment literature continues to be in its infancy, it is important to uphold best practices by exploring the applications of these therapeutic approaches in diverse community populations. In this article, we discuss recommendations for addressing challenges that have arisen while delivering mindfulness- and acceptance-based behavioral therapies to consumers of mental health services from underserved and underrepresented backgrounds (e.g., marginalized racial, religious, and socioeconomic groups). Specific case examples illustrate the challenges of promoting acceptance in the face of adversity, the acceptability of mindfulness, attending to differences in the therapist and client perspectives, and promoting the pursuit of values in the face of adversity. Clinical recommendations and suggestions for dissemination of these approaches to clinicians working with racially and ethnically diverse, underserved populations are discussed.

Explaining altruistic cooperation is one of the greatest challenges for evolutionary biology1,2,3. One solution to this problem is if costly cooperative behaviours are directed towards relatives4,5. This idea of kin selection has been hugely influential and applied widely from microorganisms to vertebrates2,3,4,5,6,7,8,9,10. However, a problem arises if there is local competition for resources, because this leads to competition between relatives, reducing selection for cooperation3,11,12,13,14. Here we use an experimental evolution approach to test the effect of the scale of competition, and how it interacts with relatedness. The cooperative trait that we examine is the production of siderophores, iron-scavenging agents, in the pathogenic bacterium Pseudomonas aeruginosa15,16,17. As expected, our results show that higher levels of cooperative siderophore production evolve in the higher relatedness treatments. However, our results also show that more local competition selects for lower levels of siderophore production and that there is a significant interaction between relatedness and the scale of competition, with relatedness having less effect when the scale of competition is more local. More generally, the scale of competition is likely to be of particular importance for the evolution of cooperation in microorganisms, and also the virulence of pathogenic microorganisms, because cooperative traits such as siderophore production have an important role in determining virulence6,9,17,18,19.

AimTo explore, for the first time, whether a modified mindfulness-based cognitive therapy (MBCT) course has the potential to reduce stress and burnout among National Health Service (NHS) General Practitioners. Background There is a crisis of low morale among NHS GPs, with most describing their workload as ‘unmanageable’. MBCT has been demonstrated to improve stress and burnout in other populations, but has not yet been evaluated in a cohort of NHS GPs. Methods NHS GPs in South East England (n=22) attended a modified version of the MBCT course approved by National Institute for Health and Care Excellence for prevention of depressive relapse. This comprised eight weekly 2-h sessions with homework (mindfulness practice) between sessions. Participants completed the Maslach Burnout Inventory (MBI) and Perceived Stress Scale (PSS) before (baseline) and then again one month (T2) and three months (T3) after attending the course. We also obtained qualitative data on participants’ experiences of the course. Findings Compliance with the intervention was very high. All GPs attended at least six sessions and all completed baseline questionnaires. At T2, data were obtained from 21 participants (95%); PSS scores were significantly lower than at baseline (P<0.001), as were MBI emotional exhaustion (P<0.001) and depersonalization scores (P=0.0421). At T3 we obtained data for 13 participants (59%); PSS scores and MBI emotional exhaustion scores were significantly lower (P<0.001; P=0.0024, respectively) and personal accomplishment scores were significantly higher (P<0.001) than at baseline. Participants reported that the course helped them to manage work pressures, feel more relaxed, enjoy their work and experience greater empathy and compassion (for self, colleagues and patients). Findings of this preliminary evaluation are promising. Further research is needed to evaluate this approach within a larger randomized-controlled trial.

Reports an error in "The experience of racism and anxiety symptoms in an African-American sample: Moderating effects of trait mindfulness" by Jessica R. Graham, Lindsey M. West and Lizabeth Roemer (Mindfulness, 2013[Dec], Vol 4[4], 332-341). In the original article, there is an error in the interpretation of the significant interaction. The second paragraph on page 6 and Fig 1 was incorrect. The corrections are present in the erratum. (The following abstract of the original article appeared in record 2013-39495-006). The current study explores the potential buffering effect of trait mindfulness on the impact of racism on anxiety symptomology in an African-American sample. Fifty-seven participants completed a questionnaire packet containing measures of anxious arousal and stress (general anxiety) symptoms, trait mindfulness, and experience of racist events. Results indicated that trait mindfulness moderated the relationship between past-year frequency of racist events and anxious arousal. Specifically, the relationship between past-year frequency of racist events and anxious arousal was significantly positive at low levels of trait mindfulness and not significant at high levels of trait mindfulness. The clinical implications of these findings and future research directions are discussed.

Hamilton's inclusive fitness theory represents one of the most important developments in evolutionary biology. In particular, the idea that individuals benefit from the reproduction of relatives (kin selection) has been extraordinarily successful in explaining a wide range of phenomena, especially cases of supposed altruism. However, recent work has emphasized how the importance of kin selection can be overestimated ? an estimate of high relatedness between interacting individuals is not in itself sufficient evidence that kin selection is responsible for promoting altruism. In particular, supposedly altruistic traits can have direct fitness benefits, and competition between relatives can reduce the importance of indirect fitness benefits.

This podcast discusses the effective altruism movement.

The occurrence of cooperation poses a problem for the biological and social sciences. However, many aspects of the biological and social science literatures on this subject have developed relatively independently, with a lack of interaction. This has led to a number of misunderstandings with regard to how natural selection operates and the conditions under which cooperation can be favoured. Our aim here is to provide an accessible overview of social evolution theory and the evolutionary work on cooperation, emphasising common misconceptions.

AbstractOur understanding of the social lives of microbes has been revolutionized over the past 20 years. It used to be assumed that bacteria and other microorganisms lived relatively independent unicellular lives, without the cooperative behaviors that have provoked so much interest in mammals, birds, and insects. However, a rapidly expanding body of research has completely overturned this idea, showing that microbes indulge in a variety of social behaviors involving complex systems of cooperation, communication, and synchronization. Work in this area has already provided some elegant experimental tests of social evolutionary theory, demonstrating the importance of factors such as relatedness, kin discrimination, competition between relatives, and enforcement of cooperation. Our aim here is to review these social behaviors, emphasizing the unique opportunities they offer for testing existing evolutionary theory as well as highlighting the novel theoretical problems that they pose.

From an evolutionary perspective, social behaviours are those which have fitness consequences for both the individual that performs the behaviour, and another individual. Over the last 43 years, a huge theoretical and empirical literature has developed on this topic. However, progress is often hindered by poor communication between scientists, with different people using the same term to mean different things, or different terms to mean the same thing. This can obscure what is biologically important, and what is not. The potential for such semantic confusion is greatest with interdisciplinary research. Our aim here is to address issues of semantic confusion that have arisen with research on the problem of cooperation. In particular, we: (i) discuss confusion over the terms kin selection, mutualism, mutual benefit, cooperation, altruism, reciprocal altruism, weak altruism, altruistic punishment, strong reciprocity, group selection and direct fitness; (ii) emphasize the need to distinguish between proximate (mechanism) and ultimate (survival value) explanations of behaviours. We draw examples from all areas, but especially recent work on humans and microbes.

Abstract In recent years there has been a large body of theoretical work examining how local competition can reduce and even remove selection for altruism between relatives. However, it is less well appreciated that local competition favours selection for spite, the relatively neglected ugly sister of altruism. Here, we use extensions of social evolution theory that were formulated to deal with the consequences for altruism of competition between social partners, to illustrate several points on the evolution of spite. Specifically, we show that: (i) the conditions for the evolution of spite are less restrictive than previously assumed; (ii) previous models which have demonstrated selection for spite often implicitly assumed local competition; (iii) the scale of competition must be allowed for when distinguishing different forms of spite (Hamiltonian vs. Wilsonian); (iv) local competition can enhance the spread of spiteful greenbeards; and (v) the theory makes testable predictions for how the extent of spite should vary dependent upon population structure and average relatedness.

A 2016 study found that yoga nidra helped employees manage stress in the workplace. The study suggests that the process of yoga nidra accesses the parasympathetic response and decreases the sympathetic nervous system response which results in more physical, mental and emotional relaxation in our bodies. In other words less anxiety.

BACKGROUND: More than a third of the approximately 10 million women with histories of interpersonal violence in the United States develop posttraumatic stress disorder (PTSD). Currently available treatments for this population have a high rate of incomplete response, in part because problems in affect and impulse regulation are major obstacles to resolving PTSD. This study explored the efficacy of yoga to increase affect tolerance and to decrease PTSD symptomatology.METHOD: Sixty-four women with chronic, treatment-resistant PTSD were randomly assigned to either trauma-informed yoga or supportive women's health education, each as a weekly 1-hour class for 10 weeks. Assessments were conducted at pretreatment, midtreatment, and posttreatment and included measures of DSM-IV PTSD, affect regulation, and depression. The study ran from 2008 through 2011. RESULTS: The primary outcome measure was the Clinician-Administered PTSD Scale (CAPS). At the end of the study, 16 of 31 participants (52%) in the yoga group no longer met criteria for PTSD compared to 6 of 29 (21%) in the control group (n = 60, χ²₁ = 6.17, P = .013). Both groups exhibited significant decreases on the CAPS, with the decrease falling in the large effect size range for the yoga group (d = 1.07) and the medium to large effect size decrease for the control group (d = 0.66). Both the yoga (b = -9.21, t = -2.34, P = .02, d = -0.37) and control (b = -22.12, t = -3.39, P = .001, d = -0.54) groups exhibited significant decreases from pretreatment to the midtreatment assessment. However, a significant group × quadratic trend interaction (d = -0.34) showed that the pattern of change in Davidson Trauma Scale significantly differed across groups. The yoga group exhibited a significant medium effect size linear (d = -0.52) trend. In contrast, the control group exhibited only a significant medium effect size quadratic trend (d = 0.46) but did not exhibit a significant linear trend (d = -0.29). Thus, both groups exhibited significant decreases in PTSD symptoms during the first half of treatment, but these improvements were maintained in the yoga group, while the control group relapsed after its initial improvement. DISCUSSION: Yoga significantly reduced PTSD symptomatology, with effect sizes comparable to well-researched psychotherapeutic and psychopharmacologic approaches. Yoga may improve the functioning of traumatized individuals by helping them to tolerate physical and sensory experiences associated with fear and helplessness and to increase emotional awareness and affect tolerance.
