Smelling Your Romantic Partner’s T-Shirt May Help You Sleep Better
It actually induces slumber as well as Melatonin.

Scent has powerful ties to emotion, allowing us to conjure up old memories after only a quick whiff of something. Now, new research out of the University of British Columbia (UBC) suggests that it can also help us sleep. No, it’s not a soothing lavender aromatherapy treatment: the study found that your romantic partner’s scent can improve your slumber, even if they aren’t sharing your bed.
Researchers analyzed sleep data from 155 participants who were given two identical T-shirts to use as pillowcases. One belonged to their romantic partner, while the other was worn by someone else, or was clean. After sleeping with the two pillowcases for two nights, the participants were asked to rate their sleep quality. The researchers also had data from actigraph sleep watches which monitored participants’ tossing and turning in bed.
As it turns out, people slept better when they slept with the pillowcase with their partner’s scent. In fact, their sleep improved by more than two percent, which is as effective as using melatonin supplements, Marlise Hofer, the study’s lead author and a graduate student in the UBC department of psychology, said in a statement.
“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 in the same statement. “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.”
Ultimately, the researchers hope that this discovery could lead to treatments for people with difficulty sleeping. Their next research project will determine whether infants sleep better when exposed to their parents’ scent.
