Experts believe that a fluffy pair of warm socks can promote better circulation throughout your body while you slumber, allowing you to achieve a more restful night’s sleep. Note that we said sleep, not other things you might want to do in bed. While keeping your socks on might be a mood killer, consider slipping your bed socks back on after intimacy time is over and bedtime is upon you.

The term “sock” may come from the Latin word soccus, which referred to a loose-fitting stocking worn by comedic actors in ancient Rome. The term could also refer to a low-heeled light shoe. Over time, the term “socc” entered Old English to refer to lightweight slippers.

The word might also derive from “sykkos,” a Greek word referring to a thin shoe worn under the sandals, like a sock would be worn under a shoe. Both Greek and Latin evolved from Proto Indo-European, a lost language that linguists believe gave rise to the languages spoken by 43% of today’s human beings. So there could be an even older version of the word “sock” we will never know about.

Without historical records to inform them, anthropologists attempt to piece together the lifestyles and habits of prehistoric humans from preserved evidence. While it’s hard to be sure, anthropologists suspect they know enough about our ancient ancestors to deduce that cave-dwelling humans probably wore socks.

Cavemen and cavewomen would have killed animals, skinned them, and wrapped those skins around their feet, securing them in place by tying them at the ankles. They probably did so to keep their feet warm during cold seasons.
