Long-term meditation practitioners have a faster psychophysiological recovery from stress, study finds

first_imgLinkedIn Share on Facebook Share The study compared 29 long-term meditation practitioners to 26 matched non-meditating controls. The long-term meditators had been practicing Buddhist meditation for least 3 years with a regularity of at least 3 hours per week.Gamaiunova and her colleagues examined how the participants’ responded to the Trier Social Stress Test, a common experimental technique for inducing a stress response, in which the participants were asked at short notice to complete a 5-minute speech and a 5-minute math task in front of an unfriendly committee, a camera and a microphone.The researchers found that long-term meditation practitioners had faster cortisol recovery from stress than controls. The long-term meditation practitioners also reported experiencing less self-conscious emotions after the stressful task.“Even though it is early to talk about conclusive evidence of robust effects of meditation on the physiology of the stress response, this study, among others, demonstrates that contemplative practice might indeed be related to the way our body deals with threats,” Gamaiunova told PsyPost.“The study shows that meditation is related to the physiological recovery from stress, and proposes an explanation supported by the data: mediators are more prone to use an emotion regulation strategy of acceptance, characterized by non-judgment and receptivity towards our experiences.”A growing body of research suggests that meditation can help in the fight against stress. For instance, a previous study, published in Psychiatry Research, found that anxiety disorder patients had reduced cortisol responses to the Trier Social Stress Test after taking a mindfulness meditation course.But the new study — like all research — includes some limitations.“First, when we talk about meditative practices, we need to keep in mind that there exist a variety of contemplative approaches that do not always work in the same manner. An increasing number of researchers design studies that allow us to differentiate the effects of different types of meditations. Future studies should help us to gain insights on what types of contemplative practices are most related to the psychobiological stress response,” Gamaiunova explained.“Second, stress response is quite complex: in order to understand how meditation practice affects our physiology, we need to investigate the complex dynamics of the stress response: are we getting stressed already anticipating something unpleasant? How long do we remain stressed after the danger is over? Meditation practice might affect some or all of the phases of our stress response.”“Third, we need to understand the psychological mechanisms underlying the beneficial effects of contemplative training on our body. Do mediators learn to appraise the stressors differently? Do they experience the same emotions going through stress? How is meditation related to emotion regulation? These questions are very important for our understanding of what makes contemplative approaches effective,” Gamaiunova added.“And, of course, we need more research on shorter interventions, as not everyone is able to dedicate thousands of hours to meditative practice.”The study, “Exploration of psychological mechanisms of the reduced stress response in long-term meditation practitioners“, was authored by Liudmila Gamaiunova, Pierre-Yves Brandt, Guido Bondolfi, and Matthias Kliegel. New research published in Psychoneuroendocrinology has found that long-term meditation practitioners have a faster cortisol recovery from stress. The findings suggest the practicing meditation can improve the psychophysiological response to stress by reducing self-conscious emotions.“Stress is responsible for a variety of negative health outcomes, and takes a toll on quality of life and well-being. Thus, research on behavioral approaches that can help to attenuate the stress response is of utmost importance,” explained study author Liudmila Gamaiunova, a PhD candidate at the University of Lausanne.“I was intrigued by previous findings indicating that certain types of meditation could help to diminish the stress response. Equally, I was interested in why it might be the case, what are the mechanisms behind this relationship?”center_img Pinterest Share on Twitter Emaillast_img read more

California revises high speed plans again

first_imgUSA: The California High Speed Rail Authority released a third substantially-revised business plan on April 2, covering construction of an initial 480 route-km of dedicated high speed tracks between Merced and the San Fernando Valley north of Los Angeles.CHSRA’s original vision of a 1 100 km network running from Sacramento in the north of the state to Anaheim in the south has now been scaled back to save $30bn from the previous projected capital cost of $98·5bn. Much of this saving comes from a decision to shelve plans to build dedicated tracks for high speed services to reach central Los Angeles and San Francisco. Instead, the existing Metrolink and Amtrak corridor between the San Fernando Valley and Anaheim and the Caltrain route from San Jose to San Francisco will be electrified and substantially upgraded at a cost of $2bn to allow shared running between high speed and commuter rail trains. Last month a memorandum of understanding for electrification and the installation of PTC on the Caltrain route was agreed by the Metropolitan Transportation Commission, five Bay Area transport agencies, two municipalities and CHSRA. The business plan calls for Caltrain electrification to be completed by 2020.Within a budget of $68·4bn, CAHSRA hopes to start construction on an ‘initial operating segment’ in the Central Valley by early next year with a view to launching commercial services by 2023. Through services giving a ‘one seat ride’ over the 832 km from Anaheim via Los Angeles to San Francisco would start in 2029. CAHSRA confirmed that $6bn in funding is already in place to start construction, whilst ‘cap and trade funds’ would be used to eliminate the need for state or federal support to complete the initial section of route.last_img read more

IEEE Releases Report on Wake-Up Radio Technology Aimed at Increasing Battery Life for Wireless Devices

first_img An overview of IEEE 802.11ba Wake-Up Radio Near-and long-term use cases Market forecasts A comparison of IEEE Wake-Up Radio to other technologies A look at potential future developments Click here to learn more. IEEE has released the IEEE Technology Report on Wake-Up Radio. Wake-Up Radio is a breakthrough technology from the IEEE 802.11ba Standards Task Group that significantly extends the battery life of devices and sensors, particularly those that are part of the Internet of Things (IoT). With the projected growth of IoT devices exceeding 20 billion by 2020, Wake-Up Radio will greatly reduce the need for frequent recharging or replacement of batteries while still maintaining optimum device performance.Energy conservation is a critical requirement for the billions of future networked devices exclusively dependent on battery power with a target operational lifetime in excess of five years. These devices are expected to make up a substantial fraction of the Internet of Things market. IEEE P802.11ba – Wake Up Radio is a key enabling energy conserving technology for the markets they will serve, and this insightful report has been crafted to help stakeholders better understand the potential of the technology and market.From smart homes and smart warehouses, to logistics and transport, to wearable health-monitoring devices and more, achieving low-power, low-latency objectives are essential for organizations designing or using IoT devices. Wake-Up Radio, running on the common standard IEEE 802.11, offers solutions to overcome design challenges, and to meet the unique requirements for low-power and low-latency in a world of ubiquitous IoT device deployments.The IEEE Wake-Up Radio is an add-on to existing IEEE 802.11 radios that substantially improve power-saving performance of IEEE 802, removing the need to compromise between power savings and latency. This makes the technology suitable for a new class of battery-powered devices that will drive innovation and exciting new applications in the market.The IEEE Technology Report on Wake-Up Radio provides:last_img read more
