We’re Attracted to the Smell of People With Different Immune Systems

About this video

Huberman’s guest describes a study in which heterosexual participants smelled sweaty T-shirts worn by members of the opposite sex and ranked how attracted they were to each scent. The guest explains that people were more drawn to the smell of those whose immune systems, examined in the genome, were most different from their own. Huberman and the guest note that similar behaviour is seen in mice, and wonder how much this influences human choice of mates and spouses.

Key takeaways

• The guest describes participants ranking attraction to sweaty T-shirts by smell alone.
• The guest explains people preferred scents from those with immune systems most different from their own.
