There are many benefits of being in a relationship. Right from having someone to keep you company and the feeling of being in love to amazing sex–good relationships can also be good for your mental health. And you’ve got your partner to thank for that.
Here’s another thing that you need to thank your partner for: his scent! Because according to a research from the University of British Columbia your partner’s scent can help you sleep better.
According to this unique study your partner has positive impact on your health
You don’t need your partner around for peaceful sleep. Just his scent–wearing his worn T-shirt can help with that–is enough to put you to sleep.
“Our findings provide new evidence that merely sleeping with a partner’s scent improves sleep efficiency,” says Marlise Hofer, the study’s lead author. “Our participants had an average sleep efficiency improvement of more than two per cent. We saw an effect similar in size to what has been reported from taking oral melatonin supplements, often used as a sleep aid,” she adds.
Researchers analysed sleep data from 155 participants who were given two identical-looking t-shirts to use instead of pillowcases. One had been previously worn by their romantic partner, and the other one had either been previously worn by a stranger or was clean.
To capture body odour on the T-shirts, the participants’ partners were given a clean t-shirt to wear for 24 hours and were asked to refrain from using deodorant and scented body products, smoking, exercising and eating certain foods that could affect their body odour. The T-shirts were then frozen to preserve their scent.
Each participant was then given two shirts to place over their pillows, without being told which one was which. They spent two consecutive nights sleeping with each T-shirt. Each morning, they completed a survey about how well-rested they felt.
This is how it impacted their sleep quality
The way they slept was objectively measured using an actigraphy sleep watch that monitored their movements throughout the night. At the end of the study, participants guessed if the shirts they had been sleeping with had previously been worn by their partner.
Participants reported feeling more well-rested on the nights when they believed they were sleeping with their partner’s scent. Moreover, regardless of their beliefs about scent exposure, data from the sleep watches indicated that objective sleep improved when participants were actually exposed to their partner’s scent.
“One of the most surprising findings is how a romantic partner’s scent can improve sleep quality even outside of our conscious awareness. 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,” added Frances Chen, an associate professor in the UBC Department of Psychology.
The researchers further mentioned 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.
By signalling recent physical proximity, the mere scent of a partner may have similar benefits.
Hofer said the research could pave the way for future work examining the efficacy of simple and effective methods of improving sleep, such as bringing a partner’s shirt the next time you travel alone.
All in all…
Not that you needed another reason to cuddle up with your partner at night, but let this study encourage you snuggle for the sake of a good night’s sleep and your health.
