The Journal of Personality and Social Psychology has published a study on sniffing men.
It has found that the scent of your male partner can help lower stress levels
“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,” said Marlise Hofer, the study’s lead author and a graduate student in the UBC department of psychology. “Our findings suggest that a partner’s scent alone, even without their physical presence, can be a powerful tool to help reduce stress.”
The survey, predominantly of straight couples, found that after a man wore a clean shirt for 24-hours his partners stress levels were significantly lowered after they smelt his shirt.
“Our findings suggest that a partner’s scent alone, even without their physical presence, can be a powerful tool to help reduce stress,” said Hofer.
The study also found that sniffing a strangers shirt increased stress 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,” said Hofer. “This could happen without us being fully aware of it.”
