音樂對年輕族群睡眠的影響

Abstract

Sleep, a vital ingredient in life, is an active and complex rhythmic state that may affected the health of people. Based on theory, sedative music may induce relaxation and distraction responses. Music also has the effect on the change of muscular energy, heart rate, respiratory rates, blood pressure, and psychological distress. Music intervention could enhance sleep quality. The purpose of this study was to investigate the effect of music for sleep in young people.Twenty people aged 20-30 years in normal state of sleep were recruited and assigned randomly to different music conditions into this study. Each participant received one night for adaptation, then randomly arranged into sleep with no music (NM), music (M), or music combined block sound (MB) in the nighttime for the rest three nights. Participants listen to sedative piano music with or without block sound one hour at sleep time. Polysomnography was used for recording of sleep and physiology variation in each subject. Outcome measures included the change of sleep parameters (sleep latency, sleep efficiency, sleep stage time percentage, awake time) and physical signs (heart rate and heart rate variability) in three different conditions for each subject. From the result of sleep promotion, young people sleep with music had a tendency of shorter period of latency to fall asleep than without music, but did not reach significant in all parameters of sleep record. However, under the three different conditions music combined block sound might enhance the effect of music for the onset of sleep in young people. Furthermore, slow down of heart rate after sleep with music was also found. In addition, the analysis of heart rate variability (HRV), there were significant difference of change in low frequency (LF) to high frequency (HF) ratio at two and half hours of asleep with music and music combined blocked sound than without music condition (p＜0.05). These may represent the increase of parasympathetic activities and decrease of sympathetic activities of the participant for better rest during sleep. These findings might suggest that soft slow music was effective on the improvement of sleep quality in young people. Music is pleasant, safe and cost-effective, can be used for promotion of good sleep in young people. However, the therapeutic effect of music in sleep for people with insomnia need further investigation.
