Objective:To investigate the differences between meditation and resting states using infrared thermal imaging(IRTI)to determine facial temperature distribution features during meditation and annotate the patterns of facial temperature changes during meditation from the perspective of traditional Chinese medicine facial diagnosis.Methods:Each participant performed 10 min meditation and 10 min resting but in different sequences.A concentration test was set as the task load,followed by a meditation/resting or resting/meditation session,during which the participants'facial temperatures were observed using IRTI.Participants were scored on the Big Five Inventory(BFI)and Mindful Attention Awareness Scale(MAAS).Results:Forehead temperatures decreased more during meditation than during the resting state.The chin temperature increased only during meditation(Pmeditation experience,there were significant differences in the temperatures of the left forehead(Pmeditation and resting state at the 10~(th)min.In the nontask state,the BFI-Extraversion showed a negative correlation with the temperature of the left forehead(R=-0.41,P=.03).In the post-task state,the temperature of the left forehead was negatively correlated with scores on the MAAS(R=-0.42,P=.02).Conclusion:Using IRTI to study meditation offers a practical solution to the challenges in meditation research.The results indicate that an increase in chin temperature may be a representative feature of a meditation state,and forehead temperature is also a potential indicator.

This paper provides a literature review of current studies investigating the effects of meditation and mind-body exercise on peripheral concentrations of brain-derived neurotrophic factor(BDNF),an important mediator of the neuroplasticity of the central nervous system and cognitive function.A literature search was conducted to collect currently published randomized controlled,non-randomized controlled and uncontrolled intervention studies.Fifteen studies were identified;and among these studies,seven were randomized controlled studies,three were non-randomized studies,and five were uncontrolled studies.Current limited evidence tends to support that mindfulness meditation and mind-body exercise(e.***.yoga and tai chi)increase circulating BDNF concentrations in healthy and diseased individuals.It is noteworthy that these findings are based on current studies with a relatively small sample size,or without a randomized controlled design.Further studies are needed to identify a definite effect of meditation or mind-body exercise on BDNF and its role in improving/maintaining brain functions in various populations.

It is worth mentioning that meditation,which acts as emotional therapy,has become popular in human lives nowadays.Some psychology-related software provides users with guided meditation.However,after experiencing this,several users cannot detect the effect of meditation on their mood and sleep quality.This study aims to investigate whether different kinds of sounds would affect meditation effectiveness.Specifically,it provides a reference for that software to improve the meditation function.In this context,meditation is defined as a mental exercise that trains attention and awareness.To test the hypothesis that white noise meditation would be the most effective one,while silent meditation is the least effective,an online meditation was carried out among 40 participants.They were divided into four conditions,A for vocal guidance,B for white noise,C for pure music,and D for silent condition.Responses were recorded using both pre-questionnaire and post-questionnaire about meditation,and then it was analyzed through bar charts.The results and hypothesis deviated insignificantly:Guided meditation is the most effective one in affecting participants’mood and sleep quality,while silent meditation is the least effective one.These results suggested that the meditation software provided do have a positive impact on users’mood calming and sleep quality improvement.By contrast,some participants who did not have meditation experience before this study support that software should also concentrate on white noise meditation.

Background: Stress is a universal experience, now more than ever due to an ongoing worldwide pandemic. Modern college students are not only faced with the external pressures of succeeding academically, but they’re also affected by a multitude of other variables that are causing their mental health to suffer. This social trend highlights the need for a simple, efficient, and immediate remedy for individuals suffering from these stressors. Objective: In this controlled study, we assessed the effects of two methods proven by existing research to have stress-relieving effects. Participating college students underwent music (Weightless by Marconi Union) and mindfulness meditation (Daily Calm) treatments. Methods: Ten college students were screened via a self-reporting questionnaire to identify any pre-existing conditions that may present as extraneous variables. Quantitative variables related to stress, such as alpha frequency waves and heart rate, were obtained during baseline and post-treatment stress-induced environments using an iWire EEG recorder and oximeter pulse monitor. Each individual underwent treatments for a duration of five minutes, each with noise-canceling headphones. Students were placed in an experimental stressor state induced by the Stroop test, which provided baseline stressor data. Subsequently, participants underwent each treatment, recording their heart rate before and after each. Upon each treatment’s conclusion, the Stroop test was administered again while alpha wave data was recorded. The final data set was analyzed using a repeated-measures Analysis of Variance (ANOVA) test and paired T-tests. Results: Participants’ data showed a decrease in both max-min and mean frequencies for both treatment methods, though the only statistically significant difference between baseline recordings was found in mean frequencies for meditation treatment. No significance or trend was found in changes in heart rate. Conclusions: We concluded that our hypothesis was not supported as the statistical tests showed

Stress can be associated with many physiologicalchanges resulting in significant decrements in human performance.Due to growing interests in alternative and complementary medicine by Westerners,many of the traditions and holistic yogic breathing practices today are being utilized as a measure for healthier lifestyles.These state-of-the-art practices can have a significant impact on common mental health conditions such as depression and generalized anxiety disorder.However,the potential of yogic breathing on optimizing human performance and overall well-being is not well known.Breathing techniques such as alternate nostril,Sudarshan Kriya and bhastrika utilizes rhythmic breathing to guide practitioners into a deep meditative state of relaxation and promote self-awareness.Furthermore,yogic breathing is physiologically stimulating and can be described as a natural"technological"solution to optimize human performance which can be categorized into:(1)cognitive function(i.e.,mind,vigilance);and(2)physical performance(i.e.,cardiorespiratory,metabolism,exercise,whole body).Based on previous studies,we postulate that daily practice of breathing meditation techniques play a significant role in preserving the compensatory mechanisms available to sustain physiological function.This preservation of physiological function may help to offset the time associated with reaching a threshold for clinical expression of chronic state(i.e.,hypertension,depression,dementia)or acute state(i.e.,massive hemorrhage,panic attic)of medical conditions.However,additional rigorous biomedical research is needed to evaluate the physiological mechanisms of various forms of meditation(i.e.,breath-based,mantra,mindfulness)on human performance.These efforts will help to define how compensatory reserve mechanisms of cardiovascular and immune systems are modulated by breath-based meditation.While it has been suggested that breath-based meditation is easier for beginning practitioners when compared to other forms of meditation more research is needed to
