what temperature do you keep your Living Area?

I think that the optimum for the older person is 21c, particularly if their health is not up to scratch.

Franbern Your daughter is right, what you are describing is a route to hypothermia, which is slow, quiet and can eventually kill you.

You do not feel cold when you have hypothermia because you cool down very slowly, so as your outer body calls down so does your core, and that is the danger, you just gently start slowing down, feeling a bit drowsy. In extremis your organs fail and you die.

I speak with experience. I first suffered from hypothermia on a sailing holiday when I was 20. On a cold day I had been in the cockpit manning a sail for about three hours when all of a sudden the skipper told me to go into the cabin and get into my sleeping bag and he called other crew members to make me a hot drink and heap more sleeping bags on me. He was an experienced offshore sailor and had recognised the symptoms. I wasn't aware of anything wrong. I felt a little spaced out, but otherwise fine. he explained it all to me later

It has happened to me a number of times since. Most recently just before Christmas, when I stood in the market in the rain queuing for vegetables. I had gone out in a wool coat not a waterproof because the rain was unexpected. My coat - and me got soaked. I then queued, outside, but undercover for an hour at the farm shop waiting to collect the turkey. Fortunately I realised what was happening and as soon as I got home I asked DD to make a hot drink, and as she was only just up she brought her still warm duvet from her bedroom and wrapped it round me. After about an hour I warmed up, but I was left exhausted and slept for several hours after.

Hypothermia is insidious and dangerous. This American site explains it better than the NHS site.

Our downstairs heating is always on 20C throughout the day, my mobility is not so good, and I spend much of my day in my recliner chair. I don’t like to feel ‘bunched up’ by a lot of restrictive clothes, and prefare light soft easy to wear garments. I also keep a single 10.5tog Cotton covered Duvet over the back of my recliner chair in case l fancy a snooze!
DH often complains that he’s too warm, and takes himself off to watch Tv upstairs where the heating is set at 18C, some nights l prefer to sleep in my big recliner and can happy sleep soundly fully reclined until l awake the next morning, having changed into my night clothes in my downstairs bathroom.

We have regular arguments about this - husband likes it warm and 'stuffy' and I like it much cooler.When it's too warm I keep dozing off. I feel as if all the oxygen is being sucked out of the air. So I go out for a walk every morning and come back refreshed.
That's during the day - at night we sleep separately and I have no heating on, window open.

We have our thermostat at 18°- 19°c. We turn it right down at bedtime as neither of us like a warm bedroom. We do have a log burning stove in the living room which we light when it's very cold.
Older people need to be warm!

i do as OP. i try not to put on heating during the daytime, as it is so expensive. i can usually mange until it comes on about 8.20pm. it then stays on, at a low setting until about 1.20am. on again for about 90 minutes 7.30am. but if there is frost i leave it on longer, for the sake of the pipes.
i am living on less than £10 a day income. and savings.

10 to 13 degrees here....with electric blanket and a heating boost when needed.....but I am a bit extreme.

I’m afraid 16 is too chilly for me at this time of year, even with layers on.

I wear base layer merino wool long sleeve vests and long johns, thermal roll neck, trousers, fleece and sometimes a down gillet indoors. I still keep the house at 22. Yes I am a cold soul!

My house is constant 16 twenty four hours a day. I sometimes do booster of individual fire/heater but that's seldom. Do dress warmly but feel absolutely top notch. I have read that 16 is the 'save the planet' aspiration. Not why I do it but, is that nonsense understanding, please?

You do exactly what I do Franbern I have mine set on 13* at night 15* in the day but if I’m cold I turn it up. I wear a thermal top and sweater I move around quite a lot keep a throw nearby for my legs if I feel cold, at 18* I’m just too hot.

For older people the room should be warm cold rooms can cause illness. I have my living room at about 19.

16 degrees is fine for bedrooms but not living areas. I feel cold when it gets to 18 degrees and put the heating on at 17.5. Over the cold weather my living room has been over 20 degrees and I have only turned it off today.
Listen to your daughter- she cares about you. It is also important to be active.

The house will get damp if the temperature is too low , I would say 18 is the minimum , I have the bedroom and corridor at 18 but the living room is 20
