The effects of listening to healing beat music on adults' recovery from exposure to stressful stimuli: A randomized controlled trial.

BACKGROUND: Musical auditory stimulation can affect the brain and autonomic nervous system, resulting in psychological and physical relaxation. In particular, listening to healing beat music with a tempo synchronized with an individual's heart rate can make a person feel comfortable. This study investigated whether healing beat music, utilized as a heartbeat-matched auditory stimulus, could be employed to improve patient recovery after exposure to stressful stimuli. METHODS: This study was a randomized controlled trial and participants were adults above age of 20 who voluntarily participated. As outcome variables, stress index, BIS index, sympathetic nerve activity, and blood pressure were measured and compared at 5 min intervals. RESULTS: Following the treatment, the stress index (F = 3.78, p < .001), BIS index (F = 5.61, p < .001), and systolic blood pressure (F = 3.14, p =.019) of the a healing beat music listening group (HBMG) were significantly lower than those of the control group (CG). More specifically, the stress index (P <.05) and the BIS index (P <.05) of the HBMG were lower than the indices of the preferred music listening group (PMG) and the CG at 30 min. CONCLUSIONS: Listening to healing beat music with a tempo synchronized with the heart rates of the participants had the effect of lowering stress index and systolic pressure. Accordingly, healing beat music may be utilized as a treatment method to relieve stress in both clinical and daily life contexts.

Effects of the Healing Beats Program among University Students after Exposure to a Source of Psychological Stress: A Randomized Control Trial.

This study is a randomized pre- and post-controlled trial to determine the effects of the Healing Beats program on anxiety, autonomic nervous balance, Bispectral (BIS) index, and heart rate among university students after exposure to a source of mental stress. Data were collected from candidates who volunteered from November 2018 to May 2019 in response to recruitment announcements. The analysis was performed using data of 99 participants in three groups: 32 in an experimental group, 35 in a placebo group, and 32 in a control group. The experimental group who received treatment via the Healing Beats program exhibited a significant effect on calming anxiety, autonomic nervous balance, BIS index, and heart rate, compared with the placebo group and the control group. The group interaction also showed a significant difference. The Healing Beats program can be used as an effective intervention for sedation in clinical situations or calmness in stressful situations in everyday life. Specifically, the Healing Beats program could serve as basic data for nursing interventions, according to the stability effect in stressful situations; it can also be applied to effective nursing practice as an initial study to confirm theoretical and practical indicators.
