Love Stinks: The Association Between Body Odors and Romantic Relationship Commitment

Anecdotal reports indicate that women dislike their partner's body odor (BO) during the breakdown of a relationship; however, whether disliking a partner's BO is associated with intentions to break up has not been empirically tested. Therefore, the aim of the current study was to investigate, for the first time, whether disliking one's partner's BOs is associated with experiencing lower commitment to a romantic relationship. Eighty participants (48 partnered, 32 single and previously partnered) completed self-report questionnaires about their current or previous romantic relationship and the amount of exposure to-and hedonic ratings of-their current or former partner's BOs. Olfactory function was also tested, and participants smelled and rated various pieces of clothing imbued with a stranger's BO. The results demonstrated that for participants who had experienced a breakup, historically higher levels of relationship commitment were associated with higher hedonic ratings of a previous partner's BOs, regardless of the type of BOs. For participants currently in a relationship, lower relationship commitment was associated with higher breakup intentions in response to smelling their partner's BOs. These preliminary results contribute evidence for the positive association between exposure to a partner's BOs and favorable hedonic appraisals of BOs; however, further research needs to be conducted in this area to investigate nuances. Lower levels of exposure to one's partner's BOs may be more indicative of relationship commitment than exposure to hedonically unpleasant BOs of one's partner. The findings are discussed with reference to their implications for interventions in relationship breakdown.
