The next time you yawn, beware – you could be sending out an erotic message to someone sitting close to you – say experts. Academics from Europe, the U.S., India and the Middle East attended the first ever International Conference on Yawning and discussed topics that ranged from “Yawning over a Life Span” to “Yawning in Non-Human Primates” to “The Theory of the Hidden Sexuality of the Yawn,” according to Dutch academic and author Wolter Seuntjens. It’s his theory that some forms of yawning send out an erotic subliminal message.
Ditching the old theory that we yawn because of lack of oxygen, they agreed that a range of emotional triggers probably sets off the yawn response. Interest, stress and even sexual desire may play a factor.
