Is that everyone's experience though? We set ours to 18 and only occasionally turned it up to 19 and it was fine all winter.

Everybody's body is different. I'm normally very resistant to cold, esp, if I'm moving, yet I cool down when I don't move, and esp. at nights (when body slows down even more), so I need a warmer environment (~20 degrees C) to live comfortably at nights.

Today I'm walking around in a T-Shirt when everyone has some kind of thin coats on, but when I sit and idle for an hour, or get hungry, I cool down considerably.

My wife is extremely resistant to heat, but this disadvantages her in normal and cold weather severely. Her baseline is 22-23 degrees C to live comfortably, with long sleeved warm clothes.

Also, temperature doesn't always indicate cold's penetration power. If the air is dry, -18 degrees C is survivable with a mid-thickness polar coat. If it's humid, try to survive 2-3 degrees C with a down / wind-resistant coat. It won't be easy.

Your observations are spot on. People are different and thus handle temperatures differently. The bit about humidity is absolutely 100% in line with my experience. I could handle -11 degrees C in Germany with clothing that would leave me freezing in the UK at -2 degrees C.

The same goes for handling heat and humidity. I grew up with average temps of 35 degrees C in a dry climate. It was not a problem at all. 28 degrees in high humidity I find unbearable.

If you need a warmer temperature at night to feel comfortable, I would strongly recommend trying out a waterbed. It is more expensive than a normal mattress but if correctly fitted to your body it is infinitely more comfortable and always the ideal temperature for you. I would also assume that it is more energy efficient to heat the (well insulated on the bottom/sides) mattress and keep the room cool than heating up the entire room.

Thanks a lot. Sleeping in the cold with a blanket is not a problem for me. My gripe is the period between dinner and bedtime. Body slows down, hence I can't heat myself even with warm clothing if the room is cold. To keep warm, I need a kind of blanket, which impedes my mobility a lot.

Also, feeling cold at night lowers my mood, and I don't want to do anything. However, I'm fine during the day when my body's running at its usual. I live with a t-shirt all year round, even.

> esp. at nights (when body slows down even more), so I need a warmer environment (~20 degrees C) to live comfortably at nights.

Adult sleep quality benefits quite a bit from even cooler temperatures at night, ~18.5 degrees C. Use a heavier blanket.

As I said elsewhere, problem is not about sleeping. It's the time period after dinner and bedtime. My body loves to sleep at colder temperatures.

Being tired, not being able to warm oneself after dinner at home because of a slowed down metabolism at 18 degrees C is not comfortable for me (yes, even with warmer clothes, socks, etc. Hot drinks helps, but temporarily).

You're describing something that is true of every human on Earth. Everyone gets cold when they don't move. Everyone's body cools down at night. You don't need 20C to sleep at night.

I've probably written 5 times on this thread already. It's not about sleeping at night.

18 can feel quite cold if you're already cold, it's drafty, or the warmth isn't distributed fairly evenly.

Read any historical story of how it used to be to live in this world and stop whining.

That’s a lot of assumptions and prejudice about me packed into a single comment. I invite you to read my comment a bit under yours.

I apologize. Was feeling particularly aggravated by the state of the world that day.

Apology accepted. We're all human, these things happen. No hard feelings here. Please take care.

We set ours to 18.5 and we felt fine al winter by simply using warmer clothes at home than what we were used to. Your mileage will vary, but for the environment warmer clothes are much friendlier than warmer houses.

Try to do office work from home with a subpar temperature. I hate it and it's unhealthy. 20 celsius is a healthy temperature, I'm not taking anything less.

I'm sure it's uncomfortable, but I'm not sure why it would be unhealthy.

Well, I do work from home, so I worked all winter at 18.5 without issues. People are different.

Then question why to even stop lowering? Most parts of Europe never goes to extreme cold. No heating needed if you wear enough clothes.

Damp and raised relative humidty is neither healthy for the buildings envelope and the occupants

Put on a sweater and more underwear. Come on. 18C (about 64.5F for Americans) is not cold.

It’s only cold me at nights, after my body slows down for the night.

Since my body cools down at night, warmer clothes doesn’t help (since I generate way less heat). I need to get under a blanket, which hampers my mobility a lot.

In the day, I’m very resistant to cold.

I've found that warm clothes combined with hot drinks (consuming the heat directly!) helps quite a bit.

A mug of mint tea just before bed keeps you warm and is also quite calming.

64 degrees is going to be extremely cold for most Americans. At least in the north where I've spent considerable time.

I grew up in a household that would keep it at 60 during the day, and 52 degrees at night in order to save money. I then took on a job that had me doing service calls into people's homes and it was eye opening that even the most poor run down apartment I'd visit would have the heat blasting at 75+. Oftentimes with a window cracked to boot.

I don't think I have a single friend these days that keeps it lower than 70, usually in the 72-74 range. And yes, I find it extremely hot when visiting.

No wonders that country is one of the worst polluters in the world. Windows open at 75F in the winter? That's just stupid. Plain stupid and irresponsible.

I set mine to 18.5, but I draught-proofed every door and, more noticeably, put plastic film taped over each window - inside and outside: already double-glazed windows became 4x so with the addition of two extra air barriers. Cost maybe €25 for seven glass doors/ windows. Bathroom temp inside 19C, behind the first layer of added plastic 17.5C, behind the glass 12.5C, behind that 10C. I also have wooden blinds - draught-proofed and lined with bubble-wrap - temp was 7.5C and actually outside was 5-6. Add: warm shower when I got home, or got up, sensible warm clothing, and whilst my neighbours thought my plastic looked crappy I was happy with my results. I also send in over-read meter readings thru the year: late december i told the truth...gas bill was actually -€30 ie €0. Waiting for the electric bill.
