If you're separated from your beloved this Valentine's Day, havinga piece of clothing near you tonight could help you sleep better, according to a new study.
Carried out by researchers from the University of British Columbia, Canada, the new study recruited 155 participants and gave them two identical-looking t-shirts to use as pillowcases while they slept.
One of the t-shirts had been worn by their romantic partner for a period of 24 hours in order to capture their body scent. The other t-shirt had either been worn by a stranger or was clean.
The participants were asked to sleep with each t-shirt over their pillow for two consecutive nights without knowing which was which. Their sleep quality was measured using an actigraphy sleep watch, which detects movement throughout the night. The next morning, participants were asked to fill in a survey saying how well rested they felt.
