Music and Sleep Hygiene Interventions for Pregnancy-Related Insomnia: An Online Randomized Controlled Trial.
Nadia Flensted Hoegholt, Camilla Eva Krænge, Peter Vuust and 2 others
PMID 39417384WHAT IT FOUND
Sleep hygiene instructions and music listening both improved sleep quality and reduced insomnia severity in pregnant women.
Adding music to sleep hygiene advice did not produce better outcomes than sleep hygiene alone.
Key findings
01Both the sleep hygiene only group and the sleep hygiene plus music group showed significant reductions in insomnia severity and improvements in sleep quality from baseline to post-intervention.
02There was no significant difference in the improvement of sleep quality or insomnia severity between the group that received music and the group that received only sleep hygiene instructions.
03Adherence to sleep hygiene instructions was significantly lower in the group that also received music compared to the group that received sleep hygiene alone.

What it does not show
Attrition was high, particularly in the music group, which may bias the results. Adherence to sleep hygiene instructions was significantly lower in the music group, making it difficult to isolate the specific contribution of music versus sleep hygiene. The reduction in insomnia severity (3.42 points) was below the commonly cited clinically important difference of 6 points, though the authors argue this may still be relevant for a population expected to worsen.
Declared interests
The authors have no conflicts of interest to disclose.
The easy way to misread this
Do not conclude that music is ineffective for sleep. The lack of added benefit may be due to lower adherence to sleep hygiene instructions in the music group, rather than music failing to work. The study design makes it hard to separate the effects of the two components.
