Forget counting sheep. If you really want a good night’s sleep, all you may need is your romantic partner’s favorite T-shirt wrapped around your pillow.
New research accepted for publication in the journal Psychological Science suggests that the scent of a romantic partner can improve your quality of sleep. This is true regardless of whether or not you are consciously aware that the scent is even present.
“A growing body of evidence has shown that close relationships are essential to our health and well being,” said Frances Chen, a researcher at the University of British Columbia, Vancouver, and co-author on the paper. “But far less is known about the role of scent in relationships and social support processes. The current study provides new evidence that the mere scent of a romantic partner improves sleep efficiency.”
