Music and Stress

Music boosts the recovery of attention after mental fatigue in healthy young male subjects: A human auditory event-related potential study

Daily life faces continuous cognitive tasks. Several methods could lessen cognitive fatigue including music. To find out how music functions in recovering cognitive fatigue, twenty-seven participants were randomly assigned to the rest group (N = 12) and the music group (N = 15). To evaluate the effects of Mozart K488 music on attention function after a continuous cognitively demanding task. Participants completed subjective questionnaires and the contingent negative variation (CNV) task before fatigue, after fatigue, and after the rest/musical intervention. EEG and ECG data were also collected during the experiment. The results showed that 5 min of Mozart K488 music resulted in improved CNV task performance in the musical intervention group. For EEG data, recoveries of the initial CNV and terminal CNV amplitude in Cz and CPz electrodes were observed and compared with the values after Mental Fatigue, which music increased the iCNV and tCNV. Alpha-ERD was lower after listening to music than after resting. Moreover, during music playing, compared to other brain regions the EEG alpha power of participants was significantly high in the central frontal region. This study demonstrates a short-term musical intervention can effectively boost the recovery of attention after Mental Fatigue.

Dance and stress regulation: A multidisciplinary narrative review

BACKGROUND

Physical exercise is known to aid stress regulation, however the effects of specific exercise types are under-researched. Dance uniquely combines several characteristics that are known to have stress regulatory effects, such as music listening. Nonetheless, dance has received only little attention in studies examining the stress regulatory effects of exercise.

OBJECTIVE

We used a multidisciplinary narrative review as a novel approach to explore the complex relationship between dance and stress by integrating psychological, neurobiological, physiological, and socio-cultural findings. In particular, we looked at the effects of music and rhythm; partnering and social contact; and movement and physical activity.

FINDINGS

There is strong empirical evidence for the beneficial stress regulatory effects of music, social contact, and movement, illustrating that dance can promote coping and foster resilience. Neurobiological research shows that these findings can be explained by the effects that music, social contact, and movement have on, amongst others, dopamine, oxytocin, and β-endorphin modulation and their interplay with the stress system. Socio-cultural considerations of the significance of dance help to understand why dance might have these unique effects. They highlight that dance can be seen as a universal form of human expression, offering a communal space for bonding, healing, and collective coping strategies.

DISCUSSION

This review is the first to integrate perspectives from different disciplines on the stress regulatory effects of dance. It shows that dance has a large potential to aid coping and resilience at multiple levels of the human experience. At the same time, we identified that the existing evidence is often still limited by a narrow focus on exercise characteristics such as intensity levels. This hinders a more holistic understanding of underlying stress regulatory mechanisms and provides important directions for future research.

Comparing the mental effects of interacting with farm animals and walking in a botanical garden

Over the past two decades, farm animal-assisted therapies have become popular. However, the effects of farm animals on healthy people's mental states have not yet been investigated. In Study 1, we aimed to explore whether positive effects of human-animal interaction (HAI) can be detected in healthy farm volunteers even after short-term (2-3 hours) work with goats and goatlings on a goat farm. We found that the participants' state anxiety decreased (p < 0.001) while their trust levels increased (p < 0.001) after interacting with goats. Nevertheless, it is possible that time spent in nature alone can have a beneficial effect on well-being. Therefore, in Study 2, we compared the results of Study 1 with those of a similar short-term outdoor treatment, walking in a botanical garden as a visitor. Similar but smaller effects were found for garden visitors. Decreases in anxiety scores and increases in trust scores were more pronounced in farm volunteers (anxiety: 25% vs 13%, p < 0.001; trust: 13% vs 3%, p = 0.002) after the treatments. Overall, the results suggest that the novel experience of interacting with goats and goatlings has a more positive effect on the mental state of healthy humans than walking in a botanical garden. This finding offer a strong foundation for developing animal assisted therapy methods for individuals with short or long term mental problems, but they can also enhance the wellbeing of mentally healthy people.

Dealing with job search reactions: How strength of music preference predicts job seekers' stress and knowledge-skill development

This research investigates the relationship between music preference strength and job search reactions, specifically stress and knowledge-skill development, with career adaptability as a mediating factor. Results obtained using a two-wave data collection procedure (wave one: N = 337; wave two: N = 188; the final sample size after matching: N = 182) reveal that music preference strength is positively correlated with career adaptability, which significantly mediates the relationship between music preference strength and both lower job search stress and greater knowledge-skill development. These findings suggest that fostering strong music preferences is associated with enhanced career adaptability, which predicts reduced stress and improved skill development during job searches. However, limitations to this research, such as the two-wave design and the exclusion of other theoretical explanations, call for caution in generalizing these results and interpreting causal relationships.

The double mediating effect of stress regulation and life satisfaction on music use as a coping mechanism and happiness in Chinese older adults during the COVID-19 pandemic

BACKGROUND

This study investigated the relationship between music use as a coping mechanism and subjective happiness among Chinese older adults (COAs) during Coronavirus disease 2019 (COVID-19); it also focused on the mediating effect of stress regulation by music and life satisfaction in this relationship.

METHODS

Participants were 329 male and female Chinese adults aged 60 years or older. Data were collected using the Sojump application for an online survey. The double mediating effect was analyzed using PROCESS Macro 3.5 Model 6.

RESULTS

The results revealed that music use as a coping mechanism and stress regulation by music were not significantly correlated with subjective happiness of COAs, whereas these were positively correlated with their life satisfaction. Additionally, life satisfaction of COAs was positively correlated with subjective happiness. Stress regulation by music and life satisfaction completely mediated the relationship between music use as a coping mechanism and subjective happiness of COAs during COVID-19. In the double mediation model, music use as a coping mechanism positively influenced stress regulation by music (β = 0.704), stress regulation by music positively influenced life satisfaction (β = 0.162), and life satisfaction positively influenced subjective happiness (β = 0.498).

CONCLUSION

Therefore, music can promote happiness in COAs in stressful situations through stress regulation and life satisfaction.

Current scenario and potential of music therapy in the management of diseases

Over the preceding years, music therapy has gained tremendous attention due to new findings of music in management of various conditions like Alzheimer's, depression, anxiety, insomnia, etc. Music is a non-invasive, patient-friendly and pleasant form of therapy with minimal or no side effects. It activates the reward pathway of brain by influencing several processes such as dopamine release, reduction in cortisol levels, increase in estrogen and testosterone levels. This review article focuses on advantages and disadvantages of music therapy, mechanism of action of music in brain and its effective applications in the management of different diseases. The article covers history of music therapy in America, Egypt, and India with practice of music therapy. The advanced effects of music therapy in autism, cancer, post-operative pain, Parkinson's disease, selective mutism, stroke, heart problems, pregnancy, eating disorders, bone fractures and obsessive compulsive disorders are discussed. Also the effect of music therapy on the quality of sleep and brain waves has been discussed. This is an established profession in western countries like America, UK, Australia, and Canada, but not in low-income countries like India where it needs to be standardized.

Selected Acoustic Frequencies Have a Positive Impact on Behavioural and Physiological Welfare Indicators in Thoroughbred Racehorses

(1) Background: Since antiquity, it is considered that sounds influence human emotional states and health. Acoustic enrichment has also been proposed for domestic animals. However, in both humans and animals, effects vary according to the type of sound. Human studies suggest that frequencies, more than melodies, play a key role. Low and high frequencies, music tuning frequency and even EEG slow waves used for 'neurofeedback' produce effects. (2) Methods: We tested the possible impact of such pure frequencies on racehorses' behavior and physiology. A commercial non-audible acoustic stimulus, composed of an array of the above-mentioned frequencies, was broadcasted twice daily and for three weeks to 12 thoroughbred horses in their home stall. (3) Results: The results show a decrease in stereotypic behaviors and other indicators such as yawning or vacuum chewing, an increase in the time spent in recumbent resting and foraging, and better hematological measures during and after the playback phase for 4 of the 10 physiological parameters measured. (4) Conclusions: These results open new lines of research on possible ways of alleviating the stress related to housing and training conditions in racehorses and of improving physical recovery.

Effectiveness of music-based interventions to address well-being in people with a vision impairment: a scoping review

OBJECTIVES

The objectives of this review were to identify the types of music-based interventions and associated accessibility challenges for people who have visual impairment (VI) and their reported effects on psychological, physiological and social well-being.

DESIGN

A scoping review was developed according to the Joanna Briggs Institute methodology and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist and guidelines. A narrative synthesis was conducted to map out the types of music-based interventions undertaken and to compare the therapeutic outcomes. The studies were evaluated according to the music reporting checklist.

RESULTS

In total 5082 records were identified, 69 full-text articles were screened and 13 studies were included. Eleven studies included younger children and teenagers, two focused on adults with acquired VI. Ten studies involved active music therapy strategies and three used passive music listening. Eleven of the studies focused on social outcomes and two reported mental health. Although the studies reported that music-based intervention strategies improved psychosocial well-being in people with a VI, conclusions could not be drawn as robust outcome measures were not generally used and only four of the studies included any statistical analysis.

CONCLUSIONS

Although potential was evident, details of intervention protocols and training requirements were not sufficiently reported and further, high-quality evidence-based studies are required.

Does Music Intervention Improve Anxiety in Dementia Patients? A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Music interventions (MIs) have been widely used to relieve anxiety in dementia in clinical settings. However, limited meta-analysis with randomized controlled trials (RCTs) on this topic has been conducted so far. A systematic search was conducted in four major databases (PubMed, EMBASE, Web of Science, and Cochrane Library) for data provided by RCTs from the inception to February 2023. The search strategy employed the terms "anxiety AND music AND dementia OR Alzheimer's disease". Thirteen RCTs (827 participants) were included. The results showed MI reduced anxiety significantly (SMD = -0.67, p < 0.001), especially for Alzheimer's disease (p = 0.007) and Mixed (p < 0.001)-type dementia. Moreover, significant improvements in agitation (p = 0.021) and depression (p < 0.001) in dementia were observed. Additionally, several psychological mechanisms which may be associated with MI were reviewed comprehensively. In conclusion, our findings support the efficacy of MI in alleviating anxiety symptoms in dementia patients. PROSPERO Registration (ID: CRD42021276646).

A qualitative study on stress, coping strategies and feasibility of music intervention among women with cancer receiving chemotherapy during COVID-19 pandemic in Vietnam

Breast and gynaecological cancer (BGC) patients receiving chemotherapy may experience high levels of stress during the COVID-19 pandemic. Music interventions may be effective in lowering their stress levels. This study explored stressors, coping strategies, and the feasibility of music interventions among BGC patients in Vietnam. An exploratory qualitative study with individual face-to-face semi-structured interviews was conducted. A convenience sample of BGC patients receiving chemotherapy was recruited from the oncology centre of a public hospital in Vietnam. Twenty patients were interviewed with open-ended questions developed based on the transactional model of stress and coping to explore stress-causing factors and coping strategies and based on guidelines for music therapy practice to explore their music preferences and perceptions. Field notes and interview transcripts were analysed following the qualitative content analysis approach. Two stressor themes were identified: undesirable experiences during treatment and patients' inability to fulfil their own roles and responsibilities. Our findings revealed a new coping strategy-self-realisation of responsibilities towards the family-that is not listed in the transactional model of stress and coping. Future psychological interventions for stress management among BGC patients should focus on raising the patients' awareness of their values and responsibilities towards their families. Three categories of preferred music genres for stress reduction were identified: religious, softly melodic, and revolutionary music. The patients were aware of the positive effects of music and had different musical preferences. This study also explored the acceptance of music interventions and facilitators and barriers to implementing them among BGC patients in Vietnam. The findings suggest that before implementing music interventions, the musical preferences, religions, and beliefs of each individual should be considered to achieve desirable results. Music interventions for BGC patients receiving chemotherapy in Vietnam are feasible. Further intervention studies are needed to evaluate their effectiveness.

Valence-arousal classification of emotion evoked by Chinese ancient-style music using 1D-CNN-BiLSTM model on EEG signals for college students

During the COVID-19 pandemic, young people are using multimedia content more frequently to communicate with each other on Internet platforms. Among them, music, as psychological support for a lonely life in this special period, is a powerful tool for emotional self-regulation and getting rid of loneliness. More and more attention has been paid to the music recommender system based on emotion. In recent years, Chinese music has tended to be considered an independent genre. Chinese ancient-style music is one of the new folk music styles in Chinese music and is becoming more and more popular among young people. The complexity of Chinese-style music brings significant challenges to the quantitative calculation of music. To effectively solve the problem of emotion classification in music information search, emotion is often characterized by valence and arousal. This paper focuses on the valence and arousal classification of Chinese ancient-style music-evoked emotion. It proposes a hybrid one-dimensional convolutional neural network and bidirectional and unidirectional long short-term memory model (1D-CNN-BiLSTM). And a self-acquisition EEG dataset for Chinese college students was designed to classify music-induced emotion by valence-arousal based on EEG. In addition to that, the proposed 1D-CNN-BILSTM model verified the performance of public datasets DEAP and DREAMER, as well as the self-acquisition dataset DESC. The experimental results show that, compared with traditional LSTM and 1D-CNN-LSTM models, the proposed method has the highest accuracy in the valence classification task of music-induced emotion, reaching 94.85%, 98.41%, and 99.27%, respectively. The accuracy of the arousal classification task also gained 93.40%, 98.23%, and 99.20%, respectively. In addition, compared with the positive valence classification results of emotion, this method has obvious advantages in negative valence classification. This study provides a computational classification model for a music recommender system with emotion. It also provides some theoretical support for the brain-computer interactive (BCI) application products of Chinese ancient-style music which is popular among young people.

Does art reduce pain and stress? A registered report protocol of investigating autonomic and endocrine markers of music, visual art, and multimodal aesthetic experience

The pain- and stress-reducing effects of music are well-known, but the effects of visual art, and the combination of these two, are much less investigated. We aim to (1) investigate the pain- and (2) stress-reducing effects of multimodal (music + visual art) aesthetic experience as we expect this to have stronger effects than a single modal aesthetic experience (music/ visual art), and in an exploratory manner, (3) investigate the underlying mechanisms of aesthetic experience, and the (4) individual differences. In a repeated-measures design (music, visual art, multimodal aesthetic experience, control) participants bring self-selected “movingly beautiful” visual artworks and pieces of music to the lab, where pain and stress are induced by the cold pressor test. Activity of the pain and stress responsive systems are measured by subjective reports, autonomic (electrocardiography, electrodermal activity, salivary alpha-amylase) and endocrine markers (salivary cortisol).

Mothers as Home DJs: Recorded Music and Young Children's Well-Being During the COVID-19 Pandemic

As the COVID-19 pandemic continues to disrupt our lives in unimagined ways, families are reinventing daily rituals, and this is likely true for musical rituals. This study explored how parents with young children used recorded music in their everyday lives during the pandemic. Mothers (N = 19) of child(ren) aged 18 months to 5 years living in the United States played the role of home DJ over a period of one week by strategically crafting the sonic home environment, based on resources provided by the authors, in response to their children's mood and state. Using a newly developed data collection tool, inspired by the Experience Sampling Method, a total of 197 episodes were collected about children's engagement with recorded music. Findings showed that while mothers utilized music to fulfill various emotional needs, they tended to use it to maintain or reinforce their child's positive mood rather than to improve a negative mood. Also, mothers' reports suggested various ways that young children engaged with music, being aligned with the multimodal nature of their musical experiences. Lastly, mothers reported that their strategic approaches to use recorded music seemed to help their children feel less distressed and happier, and this, in turn, aided in the reduction of some of the burdens associated with parenting.

Beneath the surface: The influence of music and the dark triad traits on stress and performance

Examining factors that protect against the negative repercussions of stress on everyday functioning is paramount. This experimental study investigated the effects of music listening and personality on the reduction of perceived stress and cognitive performance. Seventy adults (18–45 years, M = 22.8, SD = 6.6) completed measures of the Dark Triad traits (psychopathy, narcissism, and Machiavellianism), music preferences, and music uses, and undertook a stress-inducing procedure. Participants were randomly allocated to three groups: hip-hop/rap, classical music, control, being exposed to the respective genre or silence for 20 min after the predicted peak in stress. Results showed that classical and hip-hop/rap music equally facilitated stress reduction. Narcissism predicted lower stress when classical music preference was high. Narcissism also predicted enhanced performance but also greater stress, when paired with infrequent stress-management through music. These novel findings demonstrate how particular genres and traits, despite being predominantly negatively perceived, can enhance stress reduction or cognitive performance.

Musical Engagement and Parent-Child Attachment in Families With Young Children During the Covid-19 Pandemic

The onset of the Covid-19 pandemic has disrupted the lives of families in the United States and across the world, impacting parent mental health and stress, and in turn, the parent-child relationship. Music is a common parent-child activity and has been found to positively impact relationships, but little is known about music's role in parent-child interactions during a pandemic. The current study utilized an online questionnaire to assess the use of music in the home of young children and their parents in the United States and Canada during Covid-19 and its relationship with parents' affective attachment with their child. Musical activity was high for both parents and children. Parents reported using music for both emotion regulation and to socially connect with their children. Parent-child musical engagement was associated with parent-child attachment, controlling for relevant parent variables including parent distress, efficacy, education, and parent-child engagement in non-musical activities. These results indicate that music may be an effective tool for building and maintaining parent-child relationships during a period of uncertainty and change.

Music as a factor associated with emotional self-regulation: A study on its relationship to age during COVID-19 lockdown in Spain

The purpose of this research is to reveal the possible relational influence of age on frequency and form of music consumption, its use, and value as a factor associated with emotional self-regulation in pandemic contexts. With this objective, this study applied a transversal, descriptive and analytical design in a sample of 1377 Spaniards during the confinement of COVID-19 from March 14 to June 20, 2020. The results report that music has been an essential generalized support for living with isolation and a powerful instrument for emotional self-regulation and relief from loneliness. Although an increase of 56% in the daily use of music for self-regulation of emotions was detected, higher frequencies of consumption, mainly in solitude, and a better conception of this artistic expression are identified in the population over 51 years old. However, young people between 18 and 40 years old stood out in the use of music as a resource to alleviate loneliness. These results confirm that music seems to have arisen as one of the most used artistic expressions to cope with loneliness, to relate to the outside or as a tool to endure psychological and emotional states catalogued as negative such as anxiety, anguish and depression, among others. Likewise, they evidence its role in personal and social wellbeing in distant age ranges, and the relational influence of music and age in contexts of isolation and loneliness.

Looking through blue glasses: bioelectrical measures to assess the awakening after a calm situation

Colors can elicit cognitive and emotional states. In particular, blue colour is associated to "refresh" and "restart" effects and is suggested to enhance a wake-up after a calm situation. In this exploratory study, these claims are investigated using Electroencephalographic (EEG), Skin Conductance (SC) and pupil diameter data. The results confirmed the "wake-up effect" for subjects wearing the lenses, as measured by Global Field Power (GFP) in Theta Band, Skin Conductance Response (SCR) and pupil diameter data.

Human stress classification using EEG signals in response to music tracks

Stress is inevitably experienced by almost every person at some stage of their life. A reliable and accurate measurement of stress can give an estimate of an individual's stress burden. It is necessary to take essential steps to relieve the burden and regain control for better health. Listening to music is a way that can help in breaking the hold of stress. This study examines the effect of music tracks in English and Urdu language on human stress level using brain signals. Twenty-seven subjects including 14 males and 13 females having Urdu as their first language, with ages ranging from 20 to 35 years, voluntarily participated in the study. The electroencephalograph (EEG) signals of the participants are recorded, while listening to different music tracks by using a four-channel MUSE headband. Participants are asked to subjectively report their stress level using the state and trait anxiety questionnaire. The English music tracks used in this study are categorized into four genres i.e., rock, metal, electronic, and rap. The Urdu music tracks consist of five genres i.e., famous, patriotic, melodious, qawali, and ghazal. Five groups of features including absolute power, relative power, coherence, phase lag, and amplitude asymmetry are extracted from the preprocessed EEG signals of four channels and five bands, which are used by the classifier for stress classification. Four classifier algorithms namely sequential minimal optimization, stochastic decent gradient, logistic regression (LR), and multilayer perceptron are used to classify the subject's stress level into two and three classes. It is observed that LR performs well in identifying stress with the highest reported accuracy of 98.76% and 95.06% for two- and three-level classification respectively. For understanding gender, language, and genre related discriminations in stress, a t-test and one-way analysis of variance is used. It is evident from results that English music tracks have more influence on stress level reduction as compared to Urdu music tracks. Among the genres of both languages, a noticeable difference is not found. Moreover, significant difference is found in the scores reported by females as compared to males. This indicates that the stress behavior of females is more sensitive to music as compared to males.

A Pilot Study Exploring the Use of an Online Pre-Composed Receptive Music Experience for Students Coping with Stress and Anxiety

College/university students face many stressors as they balance their studies, work, personal relationships, and personal/family expectations. Music therapy students have additional stressors related to academic, musical, and clinical development. College/university students have increased mental health needs compared to previous generations, with volume impacting institutions. The objective of this study was to investigate the use of an online receptive music experience for music therapy students' stress and anxiety levels, and also to examine if a particular musical element was perceived as more beneficial in decreasing stress and anxiety. Twenty-three participants (undergraduate and graduate-equivalency music therapy students) engaged in a study offered online. Measures included the Spielberger State Trait Anxiety Inventory (STAI), the Stress Overload Scale (SOS), and a post-experience survey about musical element effectiveness. Results indicated that the receptive music experience elicited a significant decrease in students' stress and anxiety levels. A subscale analysis of the SOS indicated that participants had a significant decrease in personal vulnerability, and an overall decrease in event load, though this decrease was not significant. Participants' reflections about the musical elements indicated that melody was most effective and instrumentation was least effective, with groups of elements also indicated. Pilot study results support further research investigating the use of an online receptive music experience for students, professionals, and music therapy clients as a way to manage acute stress.

Listening to Relaxing Music Improves Physiological Responses in Premature Infants: A Randomized Controlled Trial

BACKGROUND

Premature infants are exposed to high levels of noise in the neonatal intensive care unit (NICU).

PURPOSE

This study evaluated the effect of a relaxing music therapy intervention composed by artificial intelligence on respiratory rate, systolic and diastolic blood pressure, and heart rate.

METHODS

A double-blind, randomized, controlled trial was conducted in the NICUs of 2 general public hospitals in Andalusia, Spain. Participants were 17 healthy premature infants, randomly allocated to the intervention group or the control group (silence) at a 1:1 ratio. To be included in the study, the subjects were to be 32 to 36 weeks of gestation at birth (M= 32.33; SD = 1.79) and passed a hearing screening test satisfactorily. The intervention lasted 20 minutes, 3 times a day for 3 consecutive days, while infants were in the incubator. Infants' heart rate, respiratory rate, and blood pressure were assessed before and after each intervention session.

RESULTS

After each session, the respiratory rate decreased in the experimental group (main between-groups effect (F1,13 = 6.73, P = .022, ηpartial = 0.34). Across the sessions, the heart rate increased in the control group (main between-groups effect, F1,11 = 5.09, P = .045, ηpartial = 0.32).

IMPLICATIONS FOR RESEARCH

Future studies can use this music intervention to assess its potential effects in premature infants.

IMPLICATIONS FOR PRACTICE

Nurses can apply the relaxing music intervention presented in this study to ameliorate the impact of the stressful environment on premature infants.

Exploring the effect of sound and music on health in hospital settings: A narrative review

BACKGROUND

Sound in hospital space has traditionally been considered in negative terms as both intrusive and unwanted, and based mainly on sound levels. However, sound level is only one aspect of the soundscape. There is strong evidence that exploring the positive aspect of sound in a hospital context can evoke positive feelings in both patients and nurses. Music psychology studies have also shown that music intervention in health care can have a positive effect on patient's emotions and recuperating processes. In this way, hospital spaces have the potential to reduce anxiety and stress, and make patients feel comfortable and secure. This paper describes a review of the literature exploring sound perception and its effect on health care.

DATA SOURCES AND REVIEW METHODS

This review sorted the literature and main issues into themes concerning sound in health care spaces; sound, stress and health; positive soundscape; psychological perspective of music and emotion; music as a complementary medicine for improving health care; contradicting arguments concerning the use of music in health care; and implications for clinical practice. Using Web of Science, PubMed, Scopus, ProQuest Central, MEDLINE, and Google, a literature search on sound levels, sound sources and the impression of a soundscape was conducted. The review focused on the role and use of music on health care in clinical environments. In addition, other pertinent related materials in shaping the understanding of the field were retrieved, scanned and added into this review.

RESULTS

The result indicated that not all noises give a negative impression within healthcare soundscapes. Listening to soothing music was shown to reduce stress, blood pressure and post-operative trauma when compared to silence. Much of the sound conveys meaningful information that is positive for both patients and nurses, in terms of soft wind, bird twitter, and ocean sounds.

CONCLUSIONS

Music perception was demonstrated to bring about positive change in patient-reported outcomes such as eliciting positive emotion, and decreasing the levels of stressful conditions. Whilst sound holds both negative and positive aspects of the hospital ecosystem and may be stressful, it also possesses a soothing quality that induces positive feelings in patients. Conceptualizing the nature of sound in the hospital context as a soundscape, rather than merely noise can permit a subtler and socially useful understanding of the role of sound and music in the hospital setting, thereby creating a means for improving the hospital experience for patients and nurses.

Influence of Music on Anxiety Induced by Fear of Heights in Virtual Reality

Music is a potent mood regulator that can induce relaxation and reduce anxiety in different situations. While several studies demonstrate that certain types of music have a subjective anxiolytic effect, the reported results from physiological responses are less conclusive. Virtual reality allows us to study diverse scenarios of real life under strict experimental control while preserving high ecological validity. We aimed to study the modulating effect of music on the anxiety responses triggered by an immersive virtual reality scenario designed to induce fear of heights. Subjects experienced a virtual scenario depicting an exterior elevator platform ascending and descending the total height of its 350 meters tall supporting structure. Participants were allocated to either a group that experienced the elevator ride with background music or without, in a between-groups design. Furthermore, each group included participants with different degrees of fear of heights, ranging from low to high fear. Recordings of heart rate, galvanic skin response, body balance, and head movements were obtained during the experiments. Subjective anxiety was measured by means of three questionnaires. The scenario produced significant changes in subjective and physiological measures, confirming its efficacy as a stressor. A significant increase in state anxiety was found between pre and post-assessment in the silence group, but not in the music group, indicating that post-stress recovery was faster in the musical group. Results suggest that music can ameliorate the subjective anxiety produced by fear of heights.

Music-based interventions in palliative cancer care: a review of quantitative studies and neurobiological literature

PURPOSE

This study aimed to review quantitative literature pertaining to studies of music-based interventions in palliative cancer care and to review the neurobiological literature that may bare relevance to the findings from these studies.

METHODS

A narrative review was performed, with particular emphasis on RCTs, meta-analyses, and systematic reviews. The Cochrane Library, Ovid, PubMed, CINAHL Plus, PsycINFO, and ProQuest were searched for the subject headings music, music therapy, cancer, oncology, palliative care, pain, anxiety, depression, mood, quality of life, prevalence, neuroscience, functional imaging, endogenous opioids, GABA, 5HT, dopamine, and permutations of these same search terms. Data for the review were comprised of articles published between 1970 and 2012. References of all the cited articles were also reviewed.

RESULTS

Available evidence suggests that music-based interventions may have a positive impact on pain, anxiety, mood disturbance, and quality of life in cancer patients. Advances in neurobiology may provide insight into the potential mechanisms by which music impacts these outcomes.

CONCLUSIONS

More research is needed to determine what subpopulation of cancer patients is most likely to respond to music-based interventions, what interventions are most effective for individual outcomes, and what measurement parameters best gauge their effectiveness.
