Study: Natural inability to block out noise impacts sleep
Published: 10 August 2010
Some people are better at blocking out sounds than others, meaning they tend to sleep better.
A process in the brain that enables some sounds to be blocked out could be the key to sleeping properly, US researchers have claimed.According to the study published by the Harvard team in journal Current Biology, some people are better at processing sounds than others, meaning they tend to get better quality rest.
The findings, reported by the BBC, were made after 12 healthy volunteers were assessed over the course of three nights.
Each was monitored on a nightly basis using an electroencephalograph, which takes note of electrical activity within the brain.
Dr Jeffrey Ellenbogen of Harvard Medical School highlighted that the research could be beneficial in helping to acknowledge disturbances to natural brain rhythms.
"We have a lot of work to do before using this in people, mostly because we want to be absolutely clear that this is safe and effective," he added.
Researchers at the University School of Medicine in West Virginia recently said that getting seven hours sleep can help improve heart health.
