How Did People in Ancient Times Survive without Central Heating?
没有集中供暖，古代人是如何生存的?
I've come across a large number of questions on Quora asking how people in ancient times managed to survive during the winter without modern central heating. It seems that many people are just outright baffled by the very idea of people living through the cold of winter without central heating.
The answer to the question of how people survived is fairly straightforward, although there are a few surprises. For instance, some people may not have known this, but there are still people living in relatively cold environments today without central heating. Also, even more surprisingly, some wealthy aristocrats in ancient Rome actually did have a kind of early form of central heating system in their villas.
Believe it or not, there are still people today who live in cold climates without modern central heating. For instance, I’m from a town in northern Indiana. In January and February, the temperatures can often get well below freezing.
I graduated from high school a couple years ago. During my senior year of high school, I had a friend who told me about how her father’s house didn’t have any central heating or air conditioning at all. She told me that, in the winter, her bedroom would often be twenty degrees Fahrenheit or colder, with ice all over the window.
I was quite astonished to hear this at the time because, although I had already known that many people in town did not have air conditioning, I had assumed that everyone in Indiana at least had heating. I asked her how she and her father kept warm in the winter without central heating.
She said that her father’s house had been built back in the nineteenth century before heating or air conditioning were invented. She said that her father didn’t have a lot of money and it was much cheaper and easier for them to simply make do without heating or air conditioning than it would have been for them to have had those things installed.
She told me that they had a small gas heater that they kept in the living room downstairs that could generate enough heat for the room, but that was the only heating they had. They tried to keep doors in the house open so the heat could spread throughout the house. She also mentioned that they always used “lots of blankets” during the winter.

People in ancient times coped with cold temperatures in a similar way to how my friend from high school did it. They didn’t have gas space heaters, but, during the winter, they would almost always keep a fire blazing on the hearth. On especially cold days, people could gather around the hearth for warmth. It was also common for people in ancient times to use blankets and furs for warmth. The colder it was, the more blankets they used.
People who lived in areas that got especially cold during the winter, such as northern Europe, normally built their homes with thick, well-insulated walls to keep in as much warmth as possible. They knew that winters were cold, so they built their homes accordingly.
People in ancient times also adjusted their clothes according to the weather. This may come as a surprise to many people, but even people in ancient Greece and Rome didn’t just wear short tunics all year round. Greece may be warmer than, say, Norway, but it can still get quite chilly in Greece during the winter. The average low temperature for the city of Athens, Greece, in the month of January is 7 °C (44.6 °F).
The Athenian historian Xenophon (lived c. 430 – c. 354 BCE) portrays his mentor, the philosopher Socrates, as referencing the practice of wearing warmer clothing during the winter and cooler clothing during the summer in his Memorabilia or Memoirs of Socrates 1.6.6. Socrates says, on page 96 of the Penguin edition, translated by Hugh Tredennick and revised by Robin Waterfield:
雅典历史学家色诺芬(Xenophon，公元前430年-公元前354年)在他的《苏格拉底回忆录》(Memorabilia or Memoirs of Socrates, 1.6.6)中描述了他的导师哲学家苏格拉底在冬天穿暖和的衣服，在夏天穿凉爽的衣服的做法。苏格拉底说，在企鹅版的第96页，由休·特雷登尼克翻译，罗宾·沃特菲尔德修订
“As for cloaks, you know that people change them because of cold or hot weather, and they wear shoes to prevent things from hurting their feet and so impeding their movements. Well, have you ever known me to stay indoors more than anybody else on account of the cold, or compete with anyone for the shade on account of the heat, or fail to walk wherever I wanted because my feet were sore? Don’t you know that those who are physically weakest by nature, if they train with a particular end in view, become better able to achieve that end, with less effort to themselves, than the strongest athletes who neglect their training?”
During the winter, many people in ancient Greece probably wore a kind of long cloak made from a single large rectangular piece of heavy woolen fabric known as a himation. This kind of cloak usually covered the body down to the ankles. People of all ages, social classes, and genders wore it. It could be worn over another garment or on its own with nothing under it.

The himation could also be wrapped around the body like a blanket. Depictions of Achilleus mourning for Patroklos in ancient Greek pottery sometimes show him completely wrapped tightly in his himation from head to toe to signify his mourning. It is easy to imagine that people might have wrapped themselves up in a similar manner for warmth on exceptionally cold days in winter.

In the Roman Empire, some buildings, such as bathhouses and villas belonging to extremely wealthy aristocrats, did have an early form of central heating system, known as a hypocaust（热炕）. Hypocausts may have been originally invented by the Greeks, but they only became more commonly used during the time of the Roman Empire.
A hypocaust operated on a fairly simple mechanism; basically, heat from a wood furnace was conducted through empty spaces underneath the floor of the building and into rooms through pipes in the walls, which were known as “caliducts.”
A hypocaust operated的运作机制相当简单;基本上，来自木炉的热量通过建筑物地板下面的空空间，通过墙壁上的管道进入房间，这些管道被称为“caliducts（暖气管道）”。
The hypocaust, however, was an extremely rare and expensive system that was never available to the majority of people in the Roman Empire. The vast majority of people who lived in the Roman Empire lived in buildings without hypocausts.
After the collapse of the western Roman Empire in the fifth century CE, hypocausts generally fell out of use in most parts of western Europe for about a thousand years. The technology was never really lost, but, in most places, the system ceased to be used. Hypocaust-like systems continued to be used in the eastern Empire, in the Arab world, and in parts of Spain.
