Noone really knows why we yawn, fascinating eh? Stop yawning.
Hardly any research has been done on yawning, as it hasn’t ever been considered to be a problem behaviour. We know it’s contagious though, because 55% of people will yawn within 5 minutes of seeing someone else yawn and scientists have recorded blind people yawning more after hearing audio of others yawning.
The anti-depressant Clomipramine had an interesting yawn-related side effect and is no longer prescribed as 5% of users suffered spontaneous orgasms.
A female patient told doctors that her depression had been cured but sheepishly asked to stay on the medication as she had experienced orgasm when she yawned, and had started deliberate yawning. Well, wouldn’t you?
A male patient also experienced orgasm, with ejaculation every time he yawned.
Although he found this both awkward and embarrassing, he elected to continue the medication because of the therapeutic benefit he obtained.
Insert Tui ad here. This Clomipramine seems to be addictive stuff, just researching it makes me force a yawn.
