Love Is in the Air


With Valentine’s Day approaching, the topic of love is something on everyone’s mind. And since scent is the only sense that directly is tied to the emotional center of the brain, it makes “scents” to talk about the fragrance of love.


Pheromones are chemical scents released in order to attract the opposite sex. They are not smelled in the same way as a fragrance, but with specialized receptors inside the nose. Pheromones are well known to work among various species of animals, however, their effectiveness in human sexual attraction is somewhat controversial. Some scientists say that human beings have “outgrown” the need for such chemical markers in choosing a mate through evolution, while others maintain their continued relevance.


Science has confirmed that people do sniff out potential love interests by gravitating to those with opposite natural immunities within our genetic makeup. The reason is that the resulting offspring will be stronger because of the combination of immunities. A Brazilian study found that, when women were given unwashed t-shirts worn by men, they rated the smell more pleasant for those men who had opposite MHC.[1]


Interestingly, when people marry those with differing MHC, (major histocompatibilty complex, which transmits information about immunities), they tend to have better, more loving and longer lasting relationships than those with similar MHC.


However, when women are on birth control pills, they tend to choose partners with the same MHC as theirs. The reason, scientists say, is that the pill tricks the body into thinking that it is pregnant, and for a pregnant woman, it is safer to surround herself with males who are family members. Women who form relationships with MHC similar men are more likely to feel sexually unsatisfied and cheat on their partners.[2]


So, assuming that you have found your perfect match, what scents can rev up the romance? Traditional romantic fragrances include roses, musk and chocolate. A study confirmed that people are, indeed, sexually/romantically stimulated by scent. However, the kinds of scents that work may surprise you. The top scent for male stimulation was a combination of pumpkin pie and lavender, followed by a licorice/doughnut blend. Women like to wear sexy perfumes with musk, but tend to be aroused more by the musk than the men.


Aromatherapy identifies a number of scents that act as an aphrodisiac, including basil, jasmine, neroli, ylang ylang, bergamot and sandalwood. So try one of these scents to infuse a little extra romance this Valentine's Day. Your partner will love it!

  1. Pheromones are mostly heard in the study of attraction and other social responses in the animal kingdom. However, a number of research have pointed out that pheromones are also found in the case of human attraction.
