Oct. 3 (UPI) -- Rotten sleep might accelerate the aging of a person's brain, partly by increasing inflammation, a new study says.
People's brains aged faster as they scored worse on a five-point scale of sleep quality, researchers reported Sept. 30 in the journal eBioMedicine.
"The gap between brain age and chronological age widened by about six months for every one-point decrease in healthy sleep score," said senior investigator Abigail Dove, a postdoctoral researcher in neurobiology, care sciences and society at Karolinska Institute in Sweden.
"People with poor sleep had brains that appeared on average one year older than their actual age," she said in a news release.
