Why not both? First, insulation works both way, so if you have hot summers and use A/C insulation will help you here. Second, I spent some time in mostly unheated house, indoors tempeature around 5C. And yes, with proper clothing, that's fine, but getting to the shower is not particularly comfortable... For sleeping, I had a heated blanket which I put between the sheets and a regular blanket. Probably not recommended…

Another consideration if you live in a damp climate is the risk of mold if you don’t heat your house to keep it dry.

> Because vasoconstriction only occurs when the core body temperature falls, it won't happen if you're dressed warmly enough. While insulating your neck and feet will greatly improve your thermal comfort, there is no need to wear gloves or caps indoors. In fact, it doesn't matter very much which parts of your body you choose to insulate - the important thing is to limit total heat loss so that the body core temperature remains stable

This may be true for many people, but I haven't found it true for me.

My wife and I reverse the stereotype of married couples and thermostats: she was raised in an area of the world that never got below 10C in Winter, and thus no buildings ever had heat. In the Winter you just put on more clothing. I was raised near the Canadian border; so our houses were always reasonably warm. She'd prefer the thermostat at 15C. We had sort of negotiated to keep it at 19C.

When I started working from home due to the lockdown, however, I had no choice but to turn up the temperature in the room I was working in: At 19C, sitting still all day, even wearing long underwear, woolen socks, and a very warm top, my feet got cold enough to get numb, in spite of my torso being almost hot enough to sweat.

Maybe if I found the right clothing, my legs would keep my feet warm again. But the "torso warm therefore extremities warm" is definitely not true for me.

EDIT: Just to be clear, my goal was to contradict the specific claim that I quoted, not to contradict the general idea of wearing more clothes. I've tried a couple of different solutions with the equipment at hand (like hot water bottles and thick socks) and not found them effective. The heat is already controlled on a per-room basis, so an additional electric heater would probably be a lot more wasteful than just turning up the temperature by one degree. I've been looking at woolen "boot slippers" online and looser-fitting garments. I'm sure I'll find a solution -- but all of these additional measures prove that "just keep your torso warm" is not always enough.

Yeah, I find that people spend the least amount of money on insulation/heat that they can. I’m from Edmonton, and the coldest I’ve ever been was the winter when I lived in London, UK, as their insulation sucks and their heating sucks. In Edmonton, that’s not possible, because you have a few days of -40C weather annually, so your pipes will freeze without proper insulation (and you’ll die).

Now, it’s not comfortable living through -40C weather, but it’s as cold inside as -5C in the UK (outside it’s way, way worse, of course).

I am from Siberia. I no longer live there, but I cannot tolerate the temperature at home lower than 23 degrees C. For the same exact reason.

It's because you're sitting all day. Get a small foot heater.

Had to laugh at your comment about Scotland because people in Maine do the same thing. Heat is either blasting or turned off. Very poor insulation.

We had a problem with this in older Chicago apartments, usually 2 flats and quads. These buildings usually had radiator heat fired by a common boiler in the basement and city mandated turn-on dates and minimum daily/nightly temperatures.

In theory each radiator has a regulator valve that allows you to moderate the amount of steam flowing through it. In reality these valves are all painted over/corroded/never worked in the first place, and all radiators run at full blast. It was not uncommon to see apartments with open windows in January to help regulate the heat produced by the radiator. Tenants didn't care because they didn't pay for the gas directly, although it was obviously built into the rents, and the land lords never wanted to spend the money to upgrade these old buildings, since the excessive usage of gas was built into everyone's rent and the upgrades were not.

Then again, given the age of those windows there probably was very little difference between them being open and closed anyways.

This problem was fixed when I moved into a new construction apartment which had a minisplit to heat/cool the living space. Until I found out that mini-splits have the same issue heating as ACs occasionally have in very hot summers; they can't provide any heat once the ambient temperature gets colder than the exterior coils (since it's literally an AC running backwards). That was a bad surprise.

I've stopped using heating altogether since I moved out of my hometown (it was -20c or less in winter). When I'm cold I just add an extra layer of cloth or do a few squats or push/pull ups, heating XXX cubic meters of air is a pure waste of energy if you're healthy That being said your flat/home insulation plays a huge role. I'm living in Germany for a few years now, when it's 0c outside it's still 18c+ indoor even w…

Tell me how you feel about that when the water in your pipes freezes. Because that is sure as hell not a good time.

Known as the Brooklyn Thermostat.
