Believe it or not, all our bodies emit a certain scent that’s unique on its own. And now science says that we might be subconsciously smelling those we met and that’s how we make friends.
The study stated that people with similar odours are more likely to make friends with each other. Researchers used a device called eNose to smell the clothes of close friends to assess the chemical signatures of the close friends’ odours on their t-shirts. As a result, close friends actually have similar body odours and if two strangers meet, the possibility of two strangers becoming friends with similar body odours is as high as 71 per cent.
So overall, researchers think body odour contains information that can predict the quality of social interactions between strangers and if they could become friends.
