Do We Swallow Spiders in Our Sleep? Myths and Truths

Myth or reality? How likely are we to swallow spiders or insects while sleeping? A widespread urban myth claims that we swallow an average of eight spiders a year in our sleep. However, according to experts, this claim is not based on any scientific study.

Entomologist Matan Shelomi states that insects avoid humans as they perceive the threat. Vibrations from our breathing and movements deter them. Even if an insect reaches our mouth, the body's natural reflexes, such as the gag reflex, will remove it.

According to Bobbi Pritt of the Mayo Clinic, swallowing an insect usually does not cause any problems, as the digestive system can handle it like any other organic matter. Exceptions include insects that bite or sting, such as bees and wasps, which can cause local pain or allergic reactions. Also, cockroaches can cause respiratory problems, and flies can carry bacteria.

In conclusion, although swallowing insects is rare, it is usually not dangerous, except in specific cases.
