It’s time to put away your sleeping pills because smelling your partner’s shirt could be the answer to your sleepless nights, a recent study suggests.
Researchers have found that the scent of your romantic partner can potentially improve your sleep quality, according to a study from the University of British Columbia.
During the research, it was bared that participants who were exposed to their lover’s scent overnight experienced better sleep. It was also revealed that even when the partner is not around as long as the scent is present, it could still lead to a good night’s sleep.
“Our findings provide new evidence that merely sleeping with a partner’s scent improves sleep efficiency. Our participants had an average sleep efficiency improvement of more than two percent,” said Marlise Hofer, the study’s lead author.
“We saw an effect similar in size to what has been reported from taking oral melatonin supplements – often used as a sleep aid,” she further said.
The researchers had analyzed sleep data from 155 participants who were asked to sleep on a pillow with two different shirts as pillowcase. One is from their partners, the other one is worn by a stranger.
The participants slept using one shirt each night for two-straight days before completing a survey each morning.
“One of the most surprising findings is how a romantic partner’s scent can improve sleep quality even outside of our conscious awareness,” Frances Chen, the study’s senior author and associate professor in the UBC department of psychology, said.
“The sleep watch data showed that participants experienced less tossing and turning when exposed to their partners’ scent, even if they weren’t aware of whose scent they were smelling,” Chen added.
The study further stated that “the physical presence of a long-term romantic partner is associated with positive health outcomes such as a sense of safety, calm and relaxation, which in turn leads to better sleep.”
