What did Ancient Romans do without toilet paper?

Many of the bathrooms uncovered at Pompeii and elsewhere were communal.

We've all been caught unawares by our digestive tract at one time or another.


It happened to the Nash family several months ago. We were nearing the end of an extended road trip, driving down a secondary highway through a sparsely populated area of Colorado at night, when one of my 9-year-old twin sons had to use the bathroom. Despite my pleading, he said he couldn't make it to the next town. (He had to poop.) So we pulled over and headed for the bushes. After he took care of his business, we realized that we didn't have toilet paper with us.

The whole dramatic episode got me thinking, and for the next couple of hours, I pondered toilet paper and the cultural nature of bathroom routines. (Cut me some slack. It was a long drive.)

Toilet paper is now such a routine part of our lives that we rarely give it any thought. That boring reality, however, should make us think—because toilet paper is an artifact, a technology, and is therefore grounded in culture.

As we finally re-entered Denver—my wife and kids blissfully asleep—I saw the Colorado state capitol building, beautifully lit on the horizon. I started thinking about the ancient Romans. With tall columns, colonnades, and a high, golden dome, the capitol is nothing if not a Roman temple to civics.

Modern American society, and Western societies more generally, tend to look back on ancient Rome as the pinnacle of Western civilization. We emulate their institutions and cultural practices. Why? Are they worth it?

When I thought more about their everyday habits, I realized that, despite all of their accomplishments, ancient Romans engaged in some practices that many people today would find thoroughly revolting. Take a minute to consider, for example, what many of those supposedly "civilized" people did when they had to go to the bathroom.

When Mt. Vesuvius erupted on August 24 in A.D. 79, Pompeii, Herculaneum, and other Roman settlements were sealed as time capsules. They were first excavated in the 18th century, and since then these sites have given us a wonderful view into ancient Roman society.

Many of the bathrooms uncovered at Pompeii and elsewhere were communal. In many cases, they were beautiful, with frescoes on the walls, sculptures in the corners, and rows of holes carved into cold, Italian marble slabs.

Roman toilets didn't flush. Some of them were tied into internal plumbing and sewer systems, which often consisted of just a small stream of water running continuously beneath the toilet seats.

In the same way that we use an American-style toilet, a Roman user would sit down, take care of business, and watch number two float blissfully away down the sewer system. But instead of reaching for a roll of toilet paper, an ancient Roman would often grab a tersorium (or, in my technical terms, a "toilet brush for your butt"). A tersorium is an ingenious little device made by attaching a natural sponge (from the Mediterranean Sea, of course) to the end of a stick. Our ancient Roman would simply wipe him- or herself, rinse the tersorium in whatever was available (running water and/or a bucket of vinegar or salt water), and leave it for the next person to use. That's right, it was a shared butt cleaner. (And of course, there were other means of wiping as well, such as the use of abrasive ceramic discs called pessoi.)

OK, so ancient Roman pooping habits seem strange, but what about their customs around pee?

As best we can tell from historic and archaeological data, ancient Romans peed in small pots in their homes, offices, and shops. When those small pots became full, they dumped them into large jars out in the street. Just like with your garbage, a crew came by once a week to collect those hefty pots of pee and bring them to the laundromat. Why? Because ancient Romans washed their togas and tunics in pee!

Human urine is full of ammonia and other chemicals that are great natural detergents. If you worked in a Roman laundromat, your job was to stomp on clothes all day long—barefoot and ankle deep in colossal vats of human pee.

(Frankly, I wonder why we haven't emulated this aspect of Roman culture in our age of green, eco-friendly, and sustainable businesses. I'm thinking of opening a chain called Urine-Urout All-Natural Laundromat. It's a sparkling business opportunity!)

As peculiar as personal hygiene practices in ancient Rome may seem to us, the historical fact is that many Romans successfully and sustainably used tersoria and washed their clothes in pee for several centuries—far longer than we've used toilet paper. Indeed, toilet paper is not a universal technology even today, as any trip to India, rural Ethiopia, or remote areas of China will make abundantly clear.

The memorable stop we made for my son in rural Colorado will always remind me of our culture's widespread dependence on toilet paper. We've become so accustomed to the stuff that we are loath to consider widely used alternatives. (Heck, even the elegant bidet gets short shrift in our society.)

As an archaeologist, this is surprising to me, especially because toilet paper was formally introduced in this country only in 1857, a comparatively short time ago. At that time, New York entrepreneur Joseph Gayetty first created commercial toilet paper; each individual paper sheet bore his name. He claimed that, in addition to their novel utilitarian function, they were medicinal and prevented hemorrhoids.

In 1890, Clarence and E. Irvin Scott developed the first toilet paper on rolls; their brand thrives today. (It happens to be my favorite. Too much information?) Like Gayetty's sheets, Scott tissue was originally marketed as a medicinal product. In the late 1920s, Hoberg Paper Company marketed Charmin brand toilet paper to women, with an emphasis on softness (thank goodness) and femininity, rather than medicinal properties that didn't actually work.

Today, toilet paper is ubiquitous in Western cultures; it's a US$9.5 billion-a-year industry in the United States. Americans, in their typical excess, use more than 50 pounds per person per year! About 1.75 tons of raw fiber are required to manufacture each ton of toilet paper. That doesn't seem sustainable, and frankly, I'm surprised that people haven't protested more as a result.

Given these numbers and the marketing efforts behind them, it's hard to argue that the use of toilet paper is somehow natural. On the contrary, toilet paper is nothing more than a technology. So the next time you're enjoying a morning constitutional, think about the fact that defecation and urination are more than biological functions; they are cultural activities that involve artifacts and technologies that change through time.

Speaking of which, it's high time that we consider changing how we clean ourselves after we use the toilet. Tersorium, anyone?

Correction: April 6, 2018

An earlier version of this piece used the term "tersoriums" for the plural form of "tersorium." After scrubbing for more information, we confirmed that "tersoria" is the correct plural form of the term. The text has also been updated to clarify that the butt-brush "cleaning" ritual varied and to note that tersoria were certainly not the only means ancient Romans used to clean themselves after defecation. We don't mean to be abrasive, but it's impossible to convey all the minutiae of personal hygiene practiced by the ancient Romans. (And would you really want to know more?)

The surprise reason sleep-deprivation kills lies in the gut

New research establishes an unexpected connection.

Reactive oxygen species (ROS) accumulate in the gut of sleep-deprived fruit flies, one (left), seven (center) and ten (right) days without sleep.

Surprising Science
  • A study provides further confirmation that a prolonged lack of sleep can result in early mortality.
  • Surprisingly, the direct cause seems to be a buildup of Reactive Oxygen Species in the gut produced by sleeplessness.
  • When the buildup is neutralized, a normal lifespan is restored.

We don't have to tell you what it feels like when you don't get enough sleep. A night or two of that can be miserable; long-term sleeplessness is out-and-out debilitating. Though we know from personal experience that we need sleep — our cognitive, metabolic, cardiovascular, and immune functioning depend on it — a lack of it does more than just make you feel like you want to die. It can actually kill you, according to study of rats published in 1989. But why?

A new study answers that question, and in an unexpected way. It appears that the sleeplessness/death connection has nothing to do with the brain or nervous system as many have assumed — it happens in your gut. Equally amazing, the study's authors were able to reverse the ill effects with antioxidants.

The study, from researchers at Harvard Medical School (HMS), is published in the journal Cell.

An unexpected culprit

The new research examines the mechanisms at play in sleep-deprived fruit flies and in mice — long-term sleep-deprivation experiments with humans are considered ethically iffy.

What the scientists found is that death from sleep deprivation is always preceded by a buildup of Reactive Oxygen Species (ROS) in the gut. These are not, as their name implies, living organisms. ROS are reactive molecules that are part of the immune system's response to invading microbes, and recent research suggests they're paradoxically key players in normal cell signal transduction and cell cycling as well. However, having an excess of ROS leads to oxidative stress, which is linked to "macromolecular damage and is implicated in various disease states such as atherosclerosis, diabetes, cancer, neurodegeneration, and aging." To prevent this, cellular defenses typically maintain a balance between ROS production and removal.

"We took an unbiased approach and searched throughout the body for indicators of damage from sleep deprivation," says senior study author Dragana Rogulja, admitting, "We were surprised to find it was the gut that plays a key role in causing death." The accumulation occurred in both sleep-deprived fruit flies and mice.

"Even more surprising," Rogulja recalls, "we found that premature death could be prevented. Each morning, we would all gather around to look at the flies, with disbelief to be honest. What we saw is that every time we could neutralize ROS in the gut, we could rescue the flies." Fruit flies given any of 11 antioxidant compounds — including melatonin, lipoic acid and NAD — that neutralize ROS buildups remained active and lived a normal length of time in spite of sleep deprivation. (The researchers note that these antioxidants did not extend the lifespans of non-sleep deprived control subjects.)

The experiments

The study's tests were managed by co-first authors Alexandra Vaccaro and Yosef Kaplan Dor, both research fellows at HMS.

You may wonder how you compel a fruit fly to sleep, or for that matter, how you keep one awake. The researchers ascertained that fruit flies doze off in response to being shaken, and thus were the control subjects induced to snooze in their individual, warmed tubes. Each subject occupied its own 29 °C (84F) tube.

For their sleepless cohort, fruit flies were genetically manipulated to express a heat-sensitive protein in specific neurons. These neurons are known to suppress sleep, and did so — the fruit flies' activity levels, or lack thereof, were tracked using infrared beams.

Starting at Day 10 of sleep deprivation, fruit flies began dying, with all of them dead by Day 20. Control flies lived up to 40 days.

The scientists sought out markers that would indicate cell damage in their sleepless subjects. They saw no difference in brain tissue and elsewhere between the well-rested and sleep-deprived fruit flies, with the exception of one fruit fly.

However, in the guts of sleep-deprived fruit flies was a massive accumulation of ROS, which peaked around Day 10. Says Vaccaro, "We found that sleep-deprived flies were dying at the same pace, every time, and when we looked at markers of cell damage and death, the one tissue that really stood out was the gut." She adds, "I remember when we did the first experiment, you could immediately tell under the microscope that there was a striking difference. That almost never happens in lab research."

The experiments were repeated with mice who were gently kept awake for five days. Again, ROS built up over time in their small and large intestines but nowhere else.

As noted above, the administering of antioxidants alleviated the effect of the ROS buildup. In addition, flies that were modified to overproduce gut antioxidant enzymes were found to be immune to the damaging effects of sleep deprivation.

The research leaves some important questions unanswered. Says Kaplan Dor, "We still don't know why sleep loss causes ROS accumulation in the gut, and why this is lethal." He hypothesizes, "Sleep deprivation could directly affect the gut, but the trigger may also originate in the brain. Similarly, death could be due to damage in the gut or because high levels of ROS have systemic effects, or some combination of these."

The HMS researchers are now investigating the chemical pathways by which sleep-deprivation triggers the ROS buildup, and the means by which the ROS wreak cell havoc.

"We need to understand the biology of how sleep deprivation damages the body so that we can find ways to prevent this harm," says Rogulja.

Referring to the value of this study to humans, she notes,"So many of us are chronically sleep deprived. Even if we know staying up late every night is bad, we still do it. We believe we've identified a central issue that, when eliminated, allows for survival without sleep, at least in fruit flies."

Withdrawal symptoms from antidepressants can last over a year, new study finds

We must rethink the "chemical imbalance" theory of mental health.
