Introduction

Music is an inherent aspect of human existence, evident in the rhythms of our heartbeats, breaths, and movements, as well as in the sounds of our laughter, cries, and songs. It serves as a means to express a wide range of emotions through various rhythms, harmonies, styles, and musical expressions. The emotional depth of musical sounds significantly impacts morale, personality, and the nurturing of human emotions.(1)

The notion of music possessing therapeutic properties has roots dating back to the writings of Aristotle and Plato, evolving over time. Defined as the intentional use of music for health and well-being, music therapy has gained recognition, aiming to improve mental and physical health. Music serves as a powerful tool for eliciting excitement, and its reception doesn't always require conscious recognition of its elements.(2) The brain's neural networks respond sensitively to musical perception, influencing arousal and mood. Various elements within music, such as mode, harmony complexity, and rhythm, contribute to emotional responses and arousal levels. In contemporary times, the adverse effects of many pharmaceutical treatments have spurred interest in alternative therapies like music, massage, and relaxation techniques.(3)

Music, deeply ingrained in human history, remains a captivating form of art used across medical, psychological, and counseling domains. As non-pharmacological methods gain popularity for pain management and anxiety relief, music therapy emerges as a promising psychological intervention across diverse conditions and diseases.(4)

Music and Attention Deficit Hyperactivity Disorder

ADHD, or Attention Deficit Hyperactivity Disorder, ranks among the most common conditions affecting individuals. Research indicates that music therapy holds promise in reducing aggression and symptoms of ADHD in children by influencing brain function. Music has been observed to elevate dopamine levels in various brain regions, curbing aggressive tendencies, while also enhancing the function of affected areas like the prefrontal regions, thereby ameliorating ADHD symptoms in children.(5)

Moreover, listening to music has shown potential in enhancing attention and memory performance. Studies have demonstrated that engaging in music, dance, and rhythmic movements positively impacts emotional and behavioral symptoms in young boys aged 5 to 7 with ADHD.(6) Implementing music therapy has proven beneficial in treating children with ADHD, particularly when combined with rhythmic body movements, either individually or in group settings. The collective impact of group therapy tends to be more pronounced than individual treatment. Considering the established connections between the brain's musical centers in the temporal lobe and areas implicated in ADHD, music may exert its therapeutic effects by altering the functioning of these neural centers, thus offering potential relief for individuals with ADHD.(7)

Music and pain

Recent research suggests that soothing music can effectively alleviate pain by engaging the brain's opioid and dopamine systems. Specifically, gentle music has been found to trigger these systems, offering relief from discomfort. In cancer patients, music therapy has emerged as a non-invasive approach to pain management.(8) Studies evaluating non-pharmacological pain relief methods, including music therapy and progressive muscle relaxation, have demonstrated their effectiveness in reducing pain levels among cancer patients. Additionally, combining progressive muscle relaxation with calming music has shown promise in alleviating fatigue and pain in individuals with breast cancer. Music's ability to stimulate opioidergic neurons and increase opioid substances like endorphins contributes to pain reduction, as evidenced by lowered heart rate and blood pressure. Furthermore, music aids in pain relief by mitigating the severity of depression and anxiety symptoms. Utilizing music therapy not only alleviates pain but also diminishes the reliance on analgesic drugs, thereby mitigating the potential side effects associated with such medications.(9)

Music and spiritual health

Research conducted on adolescent girls in Shiraz suggests that both relaxing and instrumental music significantly improve their spiritual health. Music serves as a powerful tool for expressing emotions and fostering awareness of oneself and the surrounding environment. When verbal communication falls short, music has the capacity to amplify emotions, empathy, and sympathy. It can be particularly beneficial for individuals in search of meaning, hope, and acknowledgment. Additionally, combining music with spiritual therapy has been found to reduce depression, anxiety, and stress levels in pregnant women, highlighting the profound impact music can have on spiritual well-being and mental health.

Music and anxiety treatment

The therapeutic potential of music in anxiety treatment within the medical field has garnered increasing attention in recent years. Music therapy, characterized by the deliberate use of music to achieve therapeutic goals, offers a non-invasive adjunctive approach to anxiety management.(10) Mechanistically, music modulates physiological, psychological, and neurobiological pathways implicated in anxiety, including autonomic nervous system activity, emotional regulation, and neural reward processing. Through passive listening, live performances, improvisational music-making, and relaxation techniques, music therapy engages individuals in tailored interventions aimed at reducing anxiety symptoms and promoting emotional well-being.(11) Empirical evidence supports the efficacy of music-based interventions across diverse anxiety disorders, including generalized anxiety disorder, panic disorder, social anxiety disorder, and post-traumatic stress disorder. Integrating music therapy into multidisciplinary treatment approaches in clinical settings enhances treatment outcomes and underscores the versatility and feasibility of music therapy in real-world contexts. Further research efforts should focus on elucidating optimal treatment parameters and identifying biomarkers of treatment response to advance our understanding of music's role in anxiety management within medicine.(12)

Music and addiction

The relationship between music and addiction involves complex neurobiological mechanisms. Pleasant music activates various brain regions associated with motivation, pleasure, and reward, including the nucleus accumbens, orbitofrontal cortex, amygdala, and ventral striatum. Studies have indicated that listening to music can trigger dopaminergic pathways, leading to increased dopamine release in key reward centers such as the nucleus accumbens and ventral tegmentum.(13) Additionally, music has been shown to modulate neurotransmitters like GABA in the amygdala, influencing relaxation and reward processes. However, the effects of music on addiction can vary depending on factors such as tempo and rhythm. While upbeat music may exacerbate morphine dependence, slower music appears to lack such effects. Music therapy has emerged as a potential intervention to reduce relapse rates and alleviate stress among individuals struggling with addiction, offering a non-pharmacological approach to addressing its consequences.(14) Moreover, music's analgesic effects are mediated by pathways involving oxytocin secretion, serotonin modulation, and other mechanisms distinct from inflammation or steroid hormones, highlighting its multifaceted role in pain management and addiction treatment.(15)

Music and childbirth

Music has been increasingly recognized as a valuable adjunctive therapy in childbirth, offering potential benefits for both mothers and infants. During labor, music can serve as a powerful tool to promote relaxation, reduce anxiety, and alleviate pain. By creating a calming atmosphere, music helps expectant mothers to manage stress and maintain a sense of control during the birthing process. Additionally, rhythmic music may assist in regulating breathing patterns and promoting a sense of rhythm, which can aid in pacing contractions and facilitating labor progression.(16)

Moreover, music can enhance the overall childbirth experience by fostering a positive emotional state and promoting feelings of empowerment and connection between the mother, her partner, and healthcare providers. For many women, the use of carefully selected music playlists or live performances during labor can create a supportive and comforting environment, helping them to feel more confident and empowered throughout the birthing process.(17)

Furthermore, music's benefits extend beyond labor and delivery to the postpartum period. Listening to calming music can help mothers to relax and recover from the physical and emotional demands of childbirth. It can also promote bonding between mother and baby, as soothing melodies can have a calming effect on infants and facilitate breastfeeding and nurturing behaviors.(18)

Music and cardiovascular disorder

Music has demonstrated promising effects on cardiovascular health, with research indicating reductions in resting heart rate, blood pressure, and respiratory rate. Reviews have highlighted music's ability to enhance cardiovascular and respiratory function, even in premature infants, while also alleviating stress in their parents.(19)

Moreover, studies have shown significant reductions in systolic and diastolic blood pressure among individuals undergoing dental procedures when exposed to music, suggesting its potential to mitigate physiological responses to stressors. Listening to music or instrumental sounds has been associated with decreased secretion of catecholamines, further contributing to lower blood pressure and heart rate. Music therapy may exert antihypertensive effects by addressing risk factors for cardiovascular disorders and modulating the autonomic nervous system's influence on heart rate. However, caution is warranted in specific contexts, as evidenced by findings suggesting that listening to music immediately after high-intensity exercise may temporarily impact cardio-respiratory efficiency by altering stroke volume, tidal volume, and increasing respiratory and heart rates during the recovery phase.(20)

Music and depression

Music therapy has emerged as a promising intervention for alleviating symptoms of depression, a prevalent psychological disorder associated with various biochemical, cognitive, behavioral, and psychological changes. According to the World Health Organization, depression ranks as the second leading cause of referrals to health centers as of 2020. Studies have consistently demonstrated the efficacy of music therapy in reducing depression severity across different populations, including the elderly and women. Additionally, music therapy has been shown to improve mental status in individuals with depression disorders and to alleviate symptoms in patients with dementia. Importantly, music therapy not only reduces depression but also addresses comorbid symptoms such as anxiety, enhances functional status, and increases cheerfulness and quality of life.(21) Group music therapy, in particular, has proven effective in enhancing the outcomes of psychological treatments and promoting patient adherence and engagement. Mechanistically, music's therapeutic effects are attributed to its ability to modulate endogenous opioids, improving both positive and negative emotions. Overall, music therapy represents a cost-effective and accessible intervention for depression management, offering a holistic approach to addressing the multifaceted nature of the disorder and improving overall well-being.(22)

Music and sleep

Music has been widely studied for its effects on sleep quality and duration, offering a non-pharmacological approach to improving sleep hygiene. Research suggests that listening to calming music before bedtime can promote relaxation, reduce anxiety, and facilitate the transition to sleep. Specifically, slow-tempo music with a smooth melody and minimal fluctuations in volume is particularly effective in inducing sleep. Additionally, music can serve as a distractor, diverting attention away from intrusive thoughts or worries that may interfere with falling asleep.(23)

Moreover, the rhythmic and repetitive nature of music can synchronize brain activity and promote a state of relaxation conducive to sleep onset. This synchronization may help regulate physiological processes such as heart rate and breathing, further promoting sleep induction. Furthermore, music therapy interventions involving guided imagery or progressive muscle relaxation combined with music have shown promising results in improving sleep quality among individuals with insomnia or sleep disturbances.(24)

Music and Autism

Music therapy has emerged as a promising intervention for individuals with autism spectrum disorder (ASD), offering a range of benefits across various domains of functioning. Research suggests that music therapy can improve social skills, communication abilities, emotional expression, and sensory integration in individuals with ASD. The inherent structure and predictability of music can provide a safe and structured environment for individuals with ASD to engage in meaningful interactions and express themselves creatively.

One key aspect of music therapy in autism is its ability to facilitate social engagement and interaction. Group music therapy sessions offer opportunities for individuals with ASD to practice turn-taking, joint attention, and collaborative activities in a supportive and inclusive environment. Music-based interventions such as improvisation and group singing promote peer interaction and foster a sense of belonging and connection among participants.(25)

Moreover, music therapy can address sensory sensitivities commonly associated with ASD. Through carefully selected music elements such as rhythm, tempo, and instrumentation, music therapists can help individuals with ASD regulate sensory input, reduce anxiety, and improve self-regulation skills. Additionally, music therapy techniques such as auditory-motor synchronization and rhythmic entrainment can enhance motor coordination and facilitate movement in individuals with ASD.(26)

Music and schizophrenia

Music therapy has emerged as a promising adjunctive treatment for individuals with schizophrenia, providing comprehensive benefits across social, cognitive, and emotional domains. Through group music therapy sessions, participants can cultivate interpersonal skills, foster connections with peers, and experience a sense of belonging through activities like group singing and improvisation. Additionally, music therapy interventions target cognitive deficits by incorporating structured exercises such as rhythm-based activities and memory games, while techniques like lyric analysis and music listening stimulate verbal expression and emotional processing, enhancing overall cognitive functioning.

Furthermore, music therapy serves as a valuable tool for managing emotional expression and reducing negative symptoms in individuals with schizophrenia. Engaging in music-making activities facilitates non-verbal exploration and communication of emotions, fostering emotional awareness and self-confidence. Through participation in activities like songwriting and improvisation, individuals can effectively express and process their feelings within a supportive therapeutic environment, ultimately contributing to improved emotional well-being and symptom management.(27)

Conclusion

 Music processing involves a complex interplay of neural networks distributed across various regions of the brain, including the auditory cortex, motor areas, anterior temporal lobe, and frontal regions. Research indicates that different aspects of music, such as melody and rhythm, are processed in distinct hemispheres, with the right hemisphere predominantly involved in melody processing and the left hemisphere in rhythm processing. Moreover, music is recognized as a powerful tool for eliciting emotions and has communicative functions akin to language, with specific brain regions dedicated to music processing. The findings discussed in this article underscore the diverse therapeutic effects of music, including pain relief, improvement of sleep disorders, enhancement of learning and memory, and alleviation of depression, anxiety, schizophrenia, and autism symptoms. By harnessing the positive impacts of music, there is potential for its practical application in various fields to promote well-being and improve quality of life. As our understanding of musical influences continues to grow, exploring and leveraging the therapeutic potential of music may lead to innovative interventions and approaches in healthcare and beyond.
