In 2015 German composer Max Richter released ‘Sleep’, an eight-hour ‘lullaby for a frenetic world’ and at the world premiere in London, listeners were offered beds instead of chairs.
Adults with insomnia, with the aim of improving sleep quality.
On the Epworth Sleep quality scale, music intervention showed a moderate effect (a 1 standard deviation improvement) in favour of intervention.
Music may improve sleep by enhancing relaxation (decreasing sympathetic arousal, anxiety and stress responses) and/or acting as a distraction from stressful thoughts. Different effects may depend on the type of music used, the aetiology of the insomnia and the length and duration of the intervention.
Although listening to music can lead to clinically significant improvement in subjective sleep quality, it does not appear to specifically reduce the length of time it takes to get to sleep, increase the amount of sleep someone gets, or reduce the number of times someone wakes up.
