What trait do these fragrances share? According to researchers at Chicago’s Smell & Taste Treatment and Research Foundation, they all put men in the mood. In a recent study, men aged 18 to 64 sniffed 30 different scents while scientists measured fluctuations in blood flow to their nethers. While all the aromas (including peppermint, chocolate, pink grapefruit, and florals) enhanced arousal, orange, vanilla, musk, and lavender got the biggest rise out of the guys. Researchers believe these smells increase the production of alpha brain waves, associated with a more relaxed state. According to study author Alan Hirsch, MD, reduced anxiety and inhibition lead to increased arousal. Ready, set, spritz!
