Cyclic Meditation and Sleep Quality: A Review.

Sleep science (Sao Paulo, Brazil) December 1, 2024 Deenadayalan Boopalan, Venugopal Vijayakumar, Govindasamy Karuppasamy et al.

Objectives Insufficient sleep leads to several short- and long-term physical and mental consequences. Yoga is a popularly known complementary health approach that maintains physical and mental health through asanas, meditation, and breathing techniques. Cyclic meditation (CM), derived from one of the Upanishads, is practiced by combining physical postures (asanas) with relaxation techniques....

Detecting Lucid Dreams by Electroencephalography and Eyebrow Movements.

Sleep science (Sao Paulo, Brazil) December 1, 2023 Michael Raduga, Andrey Shashkov 1 citation

Objective When metacognition arises during rapid eye movement (REM) sleep, people experience lucid dreaming (LD). Studies on this phenomenon face different obstacles. For example, its standard verification protocol requires at least three types of sensors. We hypothesized that preagreed frontalis movements (PAFMs), as a sign of lucidity, could be seen on electroencephalography (EEG) during REM...

An Overview of the Methods Used to Measure the Impact of Mindfulness-Based Interventions in Sleep-Related Outcomes.

Sleep science (Sao Paulo, Brazil) December 1, 2023 Julia Ribeiro Da Silva Vallim, Gabriela Sant'Ana Lima, Gabriel Natan Pires et al.

Introduction Systematic reviews and metanalyses have shown that mindfulness-based interventions can have positive effects on health, such as reducing anxiety, depression, and chronic pain. However, their effect on sleep-related outcomes is not yet well established. Sleep can be assessed subjectively (questionnaires, sleep logs, self-reporting) and/or objectively (actigraphy, polysomnography,...

A Retrospective Pilot Study of Imagery Rehearsal Therapy Enhanced with Narrative Therapy Principles for the Treatment of Nightmares in US Military Veterans.

Sleep science (Sao Paulo, Brazil) December 1, 2023 Ann Marie Wagner, Anne Richards, Christine Chiros et al.

Introduction Chronic nightmares are a common and disabling feature of posttraumatic stress disorder (PTSD) for which broadly effective treatments are still lacking. While imagery rehearsal therapy (IRT) demonstrates benefits for patients with idiopathic nightmares and some patients with PTSD-related nightmares, research indicates it may be less beneficial for veterans. Narrative therapy (NT) is...

Taking Heart: Cardiac Symptoms and Nightmares Differentiate Nightmare Proneness and Psychological Distress among Young Adults.

Sleep science (Sao Paulo, Brazil) March 1, 2023 William E. Kelly

Introduction Nightmare proneness, a trait-like disposition to experience frequent nightmares, has been strongly related to psychological distress. The aim of the present study was to examine if cardiac symptoms and hypothetically-related variables, nightmares, and perceived physical health could be used to differentiate nightmare proneness and psychological distress. Materials and Methods In...

Enhanced dehydroepiandrosterone levels are positively correlated with N3 sleep stage in long-term mindfulness meditation practitioners.

Sleep science (Sao Paulo, Brazil) 2022 Ravindra P. Nagendra, Talakad N. Sathyaprabha, Bindu M Kutty 11 citations

Meditation practices positively influence the neural, hormonal and autonomic systems. We have demonstrated that long-term practice of mindfulness meditation increases N3 and rapid eye movement (REM) sleep stages and bring efficient autonomic modulation during sleep. In the present study, the probable humoral correlation that could bring about these changes is evaluated. Long-term Vipassana...

'I love you': the first phrase detected from dreams.

Sleep science (Sao Paulo, Brazil) 2022 Michael Raduga 8 citations

Many people have dreams nightly and some maintain consciousness during dreams. Such dreams are referred to as lucid dreams (LD). During dreams, our speech correlates with facial muscle activity, which is hard to decode, but LD could solve this problem. The primary hypothesis of this study was that the facial muscles electric activity during LD corresponds to specific sounds. Understanding this...

Sleepwalking and prolonged partial sleep paralysis in a case of obstructive sleep apnea.

Sleep science (Sao Paulo, Brazil) 2021 Sudheer Tale, Akash Kumar, Lokesh Kumar Saini et al.

Observation of episodes of sleepwalking and prolonged partial sleep paralysis in the same patient is a rare condition. We present a case of 42 years gentleman who presented with recurrent episodes of sleepwalking and prolonged incomplete sleep paralysis. He was on tablet divalproate 1000mg/day and tablet olanzapine 5mg/day in view of a psychotic episode that occurred 4 years ago....

Nightmare frequency and nightmare distress: Socio-demographic and personality factors.

Sleep science (Sao Paulo, Brazil) 2019 Michael Schredl, Anja S Goeritz

The diagnosis of a nightmare disorder is based on clinically significant distress caused by the nightmares, e.g., sleep or mood disturbances. In order to understand nightmare etiology better empirical research should focus on studying factors that affect nightmare distress in addition to nightmare frequency. Overall, 2492 persons (1437 woman, 1055 men) completed the online survey. Nightmare...
