  • Descrição: Introduction Nearly all adolescents and young adults listen to music everyday, with music listening near its highest level in the evening. The National Institutes of Health have recommended listening to quiet music as part of the bedtime routine, and some researchers have claimed that listening to music before bedtime improves sleep efficiency to the level of hypnotic medications. These recommendations are based solely on studies in which participants self-reported their sleep quality. Methods Participants were 50 healthy young adults (M=21.2 years, 70% female). Following visual analogue ratings, participants were told to relax and listen to quiet music for 10 minutes. We standardized the music playlist to include three songs with high familiarity. The songs were played at a quiet volume (42 dB) while participants sat upright in bed with the lights dimmed (40 lux) to simulate a bedtime routine. Participants were randomly assigned to listen to the lyrical or instrumental-only versions of the songs. They then repeated visual analogue ratings prior to lights out. Experimenters were masked to conditions at all time points. Results Participants self-reported greater relaxation after listening to music in both conditions (ps<.05). In contrast to the popular notion that quiet instrumental music improves sleep quality, we observed significantly worse sleep efficiency in the instrumental condition than the lyrical condition, p<.05. Instrumental music impaired sleep quality because participants were nearly twice as likely to experience a nocturnal “earworm,” that is, a song stuck in their head. Nocturnal earworms were associated with longer sleep onset latency, lower sleep efficiency, greater time in N1, and less time in N3 (ps<.05). By contrast, polysomnography outcomes were unrelated to daytime earworms (i.e., earworms experienced the next morning). Conclusion The perceived relaxing effects of music may reinforce bedtime listening behaviors, even when that music does not objectively improve sleep. In contrast to studies that measured sleep quality using self-report scales, the current work provides polysomnographic evidence that instrumental music can worsen sleep quality, particularly when instrumental music increases susceptibility to having a song stuck in one’s mind at night.
