According to the Huffington Post, new research has indicated eight genes that may be responsible for sleep disorders like insomnia.

What’s more, the data showed that some of the genes associated with disturbed sleep identified in this study seemed to be linked to certain metabolic and neuropsychiatric diseases, too, like restless legs syndrome, schizophrenia and obesity.

 “It was [previously] known that sleep disturbances may co-occur with many diseases in humans, but it was not known that there are shared genetic components that contribute both to sleep problems and these conditions,” Richa Saxena, study co-author and assistant professor of anaesthesia at the Massachusetts General Hospital and Harvard Medical School, told The Huffington Post.
