Feeling stressed? New study says sniffing your partner’s shirt might help

Study found that women feel calmer after being exposed to their male partner’s scent

The scent of a romantic partner could be just what you need to help lower stress levels, a new University of British Columbia study has found.

The study, led by UBC graduate student Marlise Hofer, involved 96 opposite-sex couples.

The men were given a clean T-shirt to wear for 24 hours, and were told to refrain from using deodorant and scented body products, smoking and eating certain foods that could affect their scent. The T-shirts were then frozen to preserve the scent.

Meanwhile, the women were randomly assigned to smell a T-shirt that was either unworn, or had been worn by their partner or a stranger, but they were not told which one they had been given.

Each woman underwent a stress test that involved a mock job interview and a mental math task, and also answered questions about their stress levels and provided saliva samples used to measure their cortisol levels.

The study found that women feel calmer after being exposed to their male partner’s scent. Conversely, being exposed to a stranger’s scent had the opposite effect and raised levels of the stress hormone, cortisol.

“Many people wear their partner’s shirt or sleep on their partner’s side of the bed when their partner is away, but may not realize why they engage in these behaviours,” Hofer said.

“Our findings suggest that a partner’s scent alone, even without their physical presence, can be a powerful tool to help reduce stress.”

Those leading the study, including co-authors Hanne Collins and Ashley Whillans, also say that evolutionary factors could influence why the stranger’s scent affected cortisol levels.

“From a young age, humans fear strangers, especially strange males, so it is possible that a strange male scent triggers the ‘fight or flight’ response that leads to elevated cortisol,” Hofer said. “This could happen without us being fully aware of it.”

Frances Chen, the study’s senior author and assistant professor in the UBC department of psychology, said the findings could have practical implications to help people cope with stressful situations when they’re away from loved ones.

“With globalization, people are increasingly traveling for work and moving to new cities,” Chen said. “Our research suggests that something as simple as taking an article of clothing that was worn by your loved one could help lower stress levels when you’re far from home.”
