The Science of Sleep: A Scented Experience
Study leader Marlise Hofer, a graduate student in the Department of Psychology at UBC, shares the revealing findings: “Our findings provide evidence that simply sleeping with a partner's scent improves sleep efficiency. Our participants experienced an average increase in sleep efficiency of more than two percent. We saw an effect similar in size to that reported with taking melatonin supplements, often used as a sleep aid.”
Given that Americans spent US$$67.51 billion on sleep aids in 2022, it seems wise to explore healthier options before turning to supplements and medications, which are often wasteful, ineffective, and have troubling side effects.

The Study Methodology: Preserving the Perfume
But how did the research team reach this conclusion? They didn't sneak around grabbing dirty t-shirts from the laundry basket, that's for sure! The study involved 155 participants, whose partners were presented with a clean t-shirt and told to wear it for 24 hours. They were instructed to avoid using deodorant or perfumed products, as well as to refrain from smoking, intense exercise or eating foods with strong odors. The t-shirts were then frozen to preserve their aroma. (Pro tip: Keep your sweetie's t-shirt in the freezer for lonely nights!)
Participants were given two identical T-shirts to use as pillowcases: one impregnated with their partner's scent and the other clean or worn by a stranger. They were not told which was which and alternated between them for two consecutive nights. After each night, they completed a survey about their resting state, while their sleep quality was objectively measured by a sleep clock that monitored their movements throughout the night.
Positive and Surprising Results: The Unconscious Power of Aroma
At the end of the study, participants were asked to guess which t-shirt had been worn by their partner. Not surprisingly, they felt more rested on nights when they believed they were sleeping with their partner's scent. However, UBC explains that, “regardless of their beliefs about aroma exposure, sleep clock data indicated that objective sleep improved when participants were actually exposed to their partner's aroma.”
The Physical Presence and Long-Term Power of Aroma
As it turns out, the long-term physical presence of a romantic partner is linked to health benefits such as a feeling of security and reduced stress, which can result in better sleep. “By signaling recent physical proximity, the simple scent of a partner can have similar benefits,” the University notes.
Hofer highlights that the study could pave the way for more research into easy and effective ways to improve sleep, such as “taking your partner’s shirt the next time you travel alone.” So for anyone in a romantic relationship, it certainly wouldn't hurt to grab a used t-shirt to snuggle up with on nights you're apart. Now, you have a perfect excuse to do so!
Conclusion: The Perfume of Love, Your Alliance for a Refreshing Night’s Sleep
In a world where the search for a good night's sleep is constant, the findings of this study offer an unusual and romantic alternative. Sleeping with the scent of your loved one can be a simple but effective practice to improve sleep quality. Instead of resorting to pharmaceutical solutions, which often come with worrying side effects, why not try something as simple as hugging a t-shirt impregnated with the perfume of your loved one?
Ultimately, this study not only highlights the importance of emotional bonding and physical closeness in a relationship, but also suggests that scent may play a vital role in our overall well-being, even while we sleep. So, the next time you find yourself enveloped in your love's scent, enjoy not just the scent but also the prospect of a rejuvenating night's sleep. Your partner can be your best medicine for a smooth journey towards the world of dreams.
