Having trouble sleeping? Don’t bother with a cup of cocoa or counting sheep - listening to music at bedtime is the way to get a restful night, Taiwanese researchers have found.

In a paper published in the February issue of the Journal of Advanced Nursing, a team from Taiwan’s Tzu Chi University said they studied the sleep patterns of 60 people between 60 and 83 years who had difficulty sleeping.

Half were given relaxing music to listen to for 45 minutes at bedtime and half were given no help to sleep.

The team found that those who listened to a selection of soft, slow music experienced physical changes that aided restful sleep, such as lower heart and respiratory rates.

“The difference between the music group and the control group was clinically significant,” said lead author Hui-Ling Lai, vice director of nursing at the Buddhist Tzu Chi General Hospital and assistant professor at Tzu Chi University.

“The music group reported a 26 percent overall improvement in the first week and this figure continued to rise as they mastered the technique of relaxing to the sedative music.”
