A couple weeks ago we stumbled upon a few facts for Trivia Tuesday that said you will eat over 70 insects and 10 spiders in your sleep over the course of a lifetime, which is gross. However, after a recent analysis of that statement by some professional spider people, they have come to the conclusion that it’s highly unlikely that even one arachnid would meet it’s demise through your sleeping hole of doom.
Here are the facts in detail to calm your soul, courtesy of MentalFloss:
Think about it this way, says Rod Crawford, Curator of Arachnids at Seattle’s Burke Museum and a dedicated buster of spider myths: To swallow even just one spider in your sleep, a number of very unlikely circumstances all have to happen at once.
The first, Crawford says, is that your mouth needs to be open. Sure, some people sleep that way, but not everyone. No open mouth, no swallowed spiders.
Second, the spiders have to get in your bed. “A totally normal, neatly made bed,” Crawford says, “has maybe one or two spiders cross it per year.” Add some humans to the bed, and spiders really don’t want anything to do with it. “Most people roll around in their sleep,” write doctors Aaron Carroll and Rachel Vreeman in their book, Don’t Swallow Your Gum!: Myths, Half-Truths, and Outright Lies About Your Body and Health. “This rolling would probably scare the spiders from wandering anywhere close to your face.”
Third and fourth, Crawford says, the spider would have to just happen to cross your body where your mouth is and be so bold as to enter an orifice that’s exhaling warm breath. “Just try blowing on a spider and see how they react to that!” Crawford says. “It’s not attractive to them!”
Finally, you’d have to swallow the spider while sleeping, and Carroll and Vreeman point out that, “we do not automatically swallow every time something goes into our mouths.”
The odds are pretty clearly stacked against you swallowing any one spider, let alone multiple ones over the years. “The chance that all of these things would happen together—that there would be a wandering, potentially suicidal spider in close vicinity to your mouth and that they would actually wander in to the wet dark breathing space and trigger your swallowing reflex,” Carroll and Vreeman write, “is really incredibly small.”
You may sleep easy now, my child.
