How Gross Was the Past, Really?
In a Nutshell
Pre-modern hygiene was far worse than most people realize: Romans shared parasite-infested sponges, medieval streets were open sewers, and entire households bathed in the same filthy water. Medical care relied on bloodletting and surgeons who never washed their hands, killing patients who would have survived. These practices weren't stupidity—they were the best options available before germ theory and modern sanitation existed.

Right now, you're probably clean. You showered this morning or yesterday, or at worst, the day before. You have running hot water, soap that actually kills bacteria, toilet paper, and a toilet that flushes. You live in conditions that most humans who ever existed would consider a miracle. Most of them did not have any of that, and the ways they managed without it were in some cases genuinely stomach turning.
Despite being the most technically advanced civilization of the ancient world, the Romans had aqueducts delivering fresh water into the city from mountain springs miles away. They had sewer systems so large you could row a boat through the main channel. They had public bathhouses where thousands of citizens bathed every day. By the standards of their era, they were a hygienic civilization.
The Romans shared a single sponge on a stick to wipe themselves after using the toilet. It was called a tersorium, a sea sponge fixed to the end of a wooden rod roughly the length of your forearm. It sat in a bucket of saltwater or vinegar in the corner of public latrines, which were communal, open social spaces where Romans thought nothing of sitting side by side doing their business while having a conversation. When you were finished, you reached for the tersorium, used it, dipped it back in the bucket, left it for the next person. The vinegar had mild antiseptic properties and they understood this empirically even without knowing why.
