Do You Really Swallow Spiders While You Sleep?
If you’ve spent any time on the internet or chatting with friends, you’ve probably heard the spine-chilling claim that on average, a person swallows eight spiders a year while they sleep. It’s a terrifying thought, especially for those of us who aren't particularly fond of eight-legged creatures. But is there any truth to this widely believed tale? Spoiler alert: it's more fiction than fact.
Origins of the Myth
The myth that people swallow spiders while they sleep likely originated from misunderstandings about spider behavior and a healthy dose of the human tendency to exaggerate. One story suggests that the myth was intentionally spread as part of an experiment to see how easily misinformation could circulate—a testament to our love for a good story, no matter how creepy it might be.
Other stories suggest the myth may have arisen from older superstitions or even exaggerated reports from people who have found bugs in their beds. Either way, the notion that you swallow spiders while you sleep is simply not grounded in reality.
Why the Myth Doesn't Hold Up
Spider Behavior
Spiders are generally reclusive creatures. They prefer to avoid humans and spend their time in dark, undisturbed places where they can hunt for prey. The idea that a spider would voluntarily crawl into a person’s mouth is highly unlikely. Spiders are sensitive to vibrations, and the noise and movement from a sleeping person would be enough to send most spiders scurrying away, not closer.
Human Behavior
Even in our sleep, our bodies are not entirely still. We toss, turn, snore, and breathe heavily. The mouth, in particular, is a moist, warm, and noisy place—a far cry from the environment a spider would seek out. Moreover, our reflexes, even when we’re unconscious, would likely kick in if something as large as a spider entered our mouths, causing us to wake up, cough, or swallow in a way that would expel the intruder.
Lack of Evidence
There is no scientific evidence to support the idea that people swallow spiders while they sleep. Despite the prevalence of the myth, no studies or documented cases exist that confirm it as a widespread occurrence. In fact, many experts in arachnology (the study of spiders) and entomology (the study of insects) have debunked the myth as baseless.
Why Do We Believe It?
So, if it’s so unlikely, why do so many people believe that they’re swallowing spiders in their sleep? The answer lies in the power of suggestion and the way myths spread. The idea is memorable because it’s shocking and taps into common fears—namely, the fear of insects and spiders. Once the idea is planted, it’s hard to shake, especially when it’s repeated by multiple sources.
Additionally, many people enjoy sharing strange and creepy facts, which helps the myth persist over time. The idea that something so unsettling could happen without our knowledge or control also plays into deeper anxieties, making it a story that’s easy to believe even without evidence.
The Real Risks of Spiders
While the thought of swallowing a spider is unsettling, the real risks posed by spiders are minimal for most people. Of the thousands of spider species, only a small number are venomous, and even fewer are dangerous to humans. In most cases, spider bites result in mild irritation, similar to a mosquito bite. Dangerous encounters with spiders are rare, and most spiders you encounter in your home are harmless.
Conclusion: Rest Easy
The next time you hear someone claim that you swallow eight spiders a year in your sleep, you can confidently debunk the myth. Rest easy knowing that your slumber is unlikely to be interrupted by an unwelcome eight-legged visitor. And remember, not everything you hear—especially on the internet—is true. The world is full of myths, but this one, thankfully, is just a figment of our imaginations.
