I find that in cold rooms, my fingers slow down even if I'm warmly dressed.
typing with cold fingers might be a recipe for arthritis.
Going back and forth over winter break I definitely noticed a productivity shift being some place I was warm and comfortable.
Perhaps there are less noticeable psychology benefits for it being cold but I do not think being uncomfortable and dealing with it is a long term strategy for success. And probably completely impractical if you live with other people in the same house.
If that isn't sufficient, there are still cheaper ways to deal with it than adjusting the furnace. A low power radiative space heater (the sort with a reflective dish) can be very efficient at heating up the person it's pointed at without heating up the whole room. Having a warm drink to pick up and sip on also helps; it'll warm your fingers directly and also give your core a little boost of heat. Heated electric blankets are also extremely effective.
Bathrooms and kitchens are a special case, which can be addressed with ventilation. One of the upsides of keeping your home cool in the winter is it's much cheaper to circulate in new air from outside. You get to have fresh air all winter without paying to heat all that air up. I believe fresh air throughout the year has many health benefits.
It might be like you said only if you don't use that room, or you have a big house so maybe you don't use most rooms and then you don't fill them with humidity from your own breath. Walls are cold but also dry.
Opening the windows in the winter is how you let all that humidity out.
Absolutely, being able to open your windows is a big advantage of keeping your thermostat low.
Also, they either a) don't own a piano, or b) don't care about taking care of the piano they own.
Parents in nordic countries leave their babies outside bundled up in strollers in the winter to nap.
The key point here with this napping thing that did the rounds is that this is just for short naps. People in Norway/Finland do not leave their babies in a cold environment for long periods of time. Presumably the main reason they do this cold outside nap is that it's easier to get a baby to fall asleep in a pram (safely wrapped up) but very disruptive to then bring it inside, where it will be warm, have to undress it and then inevitably wake it. But I don't know, there are probably also other reasons. But parents in nordic countries are the same as everyone else when it comes to heating their homes appropriately, especially for night time sleeping.
Personally I would imagine even things like eating would be harder if the room is too cold and the infant must always be maximally layered up. It doesn't need to be any harder.
As for guests, you can turn up the heat when guests come to stay and still see dramatic energy savings, vs running the heat full blast the whole winter.
Anyway, enjoy your... [checks thread]... bathtub waste water heat reclaimer. I'm sure that will make a big difference to your energy bill when your thermostat is turned up to 30C in January.

Which lie do you do want to believe for making your poorer?
- have one fewer child (60 tons of carbon dioxide equivalents)
- live car free (2.5 tons)
- avoid one round-trip trans-Atlantic flight (1.5 tons)
- Buy green energy (1.3 tons)
- Buy a more efficient car (1.2 tons)

But instead people focus on recycling and replacing lightbulbs while paying no attention to the 20 flights they took last year.
Perhaps even making inaccurate value judgements on those that didn't recycle that year but also took 0 flights.
