What is the coldest temperature you can comfortably sleep in?

This comes up every year and we get more and more extreme posts about the room temperature they tolerate before heating is switched on. iirc 8c was the lowest.

I post this article each year:

Quote:
24C - top range of comfort
21C - recommended living room temperature
Less than 20C - death risk begins
18C - recommended bedroom temperature
16C - resistance to respiratory diseases weakened
12C - more than two hours at this temperature raises blood pressure and increases heart attack and stroke risk
5C - Significant risk of hypothermia

Personally I like the temperature to be at least 21C when sitting down watching TV etc.

I don't have a thermometer in my bedroom so don't know what the temperature is. However the heating isn't on unless the outside temperature is well below freezing.

the chart gives 18C for a bedroom which is my comfort level for the living-room.

It doe snt really make much difference the temperature of the air that you breathe. I ve slept in minus 10 in a down sleeping bag and had a good nights sleep. Heating the bedroom up is just completely wasteful. Powercuts are forecast this winter, global warming is thrust down our throats and people bleat on about the air temperature of what they breathe whilst sleeping. Its not the temperature of the air you breathe but the core temperature of your body,. so insulate that properly . Electric blankets and hot water bottles,blankets rather than a crude single duvet which is either too hot or too cold.

It's not so bad, the way things are going, we will all be converted sunni muslims long before we re-engage with logic. Lets keep building those mosques and islamic schools David.... The Koran must a verse somewhere on who to kill depending on their sleeping habits.. and who gets the virgins in paradise for sleeping well..

I sleep in a campervan whilst working away throughout the year... coldest i ever did was about -12C... on the flipside I have woken in the afternoon whilst doing night shift and the temp inside the van was about 38C which is over 100F! Give me spring and autumn anyday! :rotfl:

I'm clearly no hero, neither do I intend to be. My living room is set at 21.5C, the bedrooms at 19C and other areas somewhere in between (excepting bathroom which is slightly warmer at 22C).

The question was about comfort, not "how low can you go". These temperatures for me are the most comfortable.

Same here.


It went below zero last night, clear frost in the early hours when I took the dog for a walk. On the allotment the hens weren't impressed with the temp and didn't all run out when I opened up. There was a good layer of ice on the drinking troughs.


I have modern double glazing and draft excluders plus the curtains closed, but the temp still drops, lots of condensation on the inside (not between glazing), totally cold on the outside compared to inside.


It dropped to about 66f during the day yesterday (heating off) and that feels cold.

Well there was a hard white frost, and thick fog here over night, but we find it ok without the heating on. Jumpers over PJs, thick bed socks, and duvet, which I taper around my body. I stayed lovely and warm.

If it's "comfort" you are talking about, there are more considerations than simply air temperature. Humans perceive temperature as the rate of loss of energy as heat from their bodies. Therefore humidity, draughts and radiated energy all come into play.

For me, 16C is fine under a duvet. We heat to 18C in the 45mins before going to bed, then heat loss takes us down to 16C overnight with the current low single figure outdoor temps. Would like to improve that with less ventilated heatloss and improved insulation, but those are projects for the future!

In our house, the heating is off at 9pm (if its been on at all), with the thermostat set around 18oC. Usually in bed by 10pm, then heating goes on at 4:45am to get up at 5:15. The bedroom gets as cold as it gets, if it's really cold, we get a duvet from the spare bedroom. Not sure what the temperature of the heating has to do with the temperature in bed when there's 2 of you snuggling under a cosy duvet, even without PJ's !
