The difference there is the humidity making you feel cold.
I live in the Yukon where -40C is the standard daytime temp for months, and I'm perfectly happy/used to it.
I felt cold to my bones in the UK.
- kortilla 6y agoThe comment isn’t about the temps outside, it’s inside the house. The point was that in really cold places people have to have good heating and insulation so the house feels better than places with more mild winters.
- grecy 6y agoThe humidity is still a big factor inside, and it's why you feel colder than in places with low humidity.
- cududa 6y agoOdd you were downvoted down much for mentioning that humidity impacts how we feel temperatures..
- fulafel 6y agoHumid -40C air becomes very dry +20C air when it gets inside a heated house. Saturated vapour density, the basis of relative humidity, about doubles every 10C.
- grecy 6y agoHave you ever experienced Humid -40C air? It doesn't happen. I've had very humid -25C air in Alaska, and wearing literally everything I own (which is perfect at -48C), I was freezing cold for the entire day, even when running, snowboarding, jumping up and down and beating my chest.
- widforss 6y agoThing is, it's almost always close to 100 % humidity when it's cold, since the air can hold so little vapor.
- UnFleshedOne 6y agoI don't think it is, unless temperature stays constant or there is incoming source of water vapor. It reaches 100% when it is coldest in the night and all water deposits down as frost (to provide exercise to people parking outside), then it warms up and the air is dryer. Bigger the temp swings drier the air outside. Applies to continental climate though, when you are near sea you probably have air constantly replaced with humid air.
- Majromax 6y ago> Have you ever experienced Humid -40C air? It doesn't happen. > I've had very humid -25C air in Alaska You haven't had very humid -25C air, in an absolute sense. Take a look at a vapour pressure calculator (https://www.omnicalculator.com/chemistry/vapour-pressure-of-water https://www.omnicalculator.com/chemistry/vapour-pressure-of-...): the vapour pressure of water at -25C is about 63 Pa, but about 13 Pascals at -40C. The difference of 50 Pa is trivial compared to the ~100,000 Pa pressure of air at sea level. Once you're below 0C, there just isn't enough water around in a vapour (or suspended) phase to have much impact. A Globe and Mail article from 2016 discussed this phenomenon (https://www.theglobeandmail.com/life/health-and-fitness/fitness/is-damp-cold-really-the-worst/article28346087/ https://www.theglobeandmail.com/life/health-and-fitness/fitn...). Its conclusions were still tentative, but the strongest correlate of the effect seemed to be cloud cover, where bright sunlight felt warmer despite colder air temperatures.
- fulafel 6y agoFor indoor humidity, it's the same for -25C weather as for -40C. Its going to be dry when heated up.
- giantg2 6y agoAgree. Humidity and altitude play a huge role in how cold it feels (and in how effective the cold is - specific heat).

- DoofusOfDeath 6y agoHow do you folks in the Yukon manage air humidity inside your houses during the winter? I would think that by default, the indoor heated air would be so dry that it would cause havoc on your sinuses.
- leipert 6y agoNot from there, but a humidifier? My grandma always had a little thing filled with water hanging on the radiator during winter.
- grecy 6y agoMany, many people struggle with dry and cracked skin (hands, face), blood noses, etc. For me personally I do notice it whenever I leave and come back, though I seem to adjust OK. I use moisturizer a lot.
