You are either very disingenuous, or have trouble with reading comprehension. The point is, if your hands get cold easily it's not possible to go too low in temperature without discomfort. Of course while having sufficiently warm clothing to have a warm core, as you said earlier.
The 4% figure I mentioned is from the Wikipedia abstract; I haven't bothered to check the research, but I believe it grounds this firmly in the "common" territory instead of the "I never heard of such a thing in my life".
Yeah I am already wearing a sweater, warm pants, wool slippers with socks and a beanie / hat. The hands are unexposed and I'm thinking at this point I need a different slippers that are bit more breathable. Also staying warm with breathable fabrics can be somewhat deceptive, because your dehydrating yourself faster via sweat your not perceiving.
Wool doesn't work well for me due to skin issues unless I cover it with a layer of nylon / cotton. Yes I've tried good merino wool, and it's still minorly irritating. I've given up on most wool that touches my skin.
Also my apartment is in a fairly temperate place, and what is hot / cold is a bit weird. The floor is a fairly cold hardwood floor, and I think it sucks a lot of heat out somehow. I'm not in a place that is consistently cold, it's only cold for like 4 months, so places here are not very well designed for it. It's also not carpet which probably solves a lot of the cold floor problems via it's built in insulation.
Also I'm more perceptive about my body state than probably most people and try to avoid wearing antiperspirant when I know I'm not going out that day with WFH. Your are probably blocking a lot of the sweating your armpits would do in this modern age as a result, and I believe we should making clothing that keeps that area a little bit more cool.
My internal body temperature can run hotter if I start eating a lot of carbs and more calories, but then I start consistently gaining weight so I don't do that.
I'm also more doing this as a challenge, I can definitely afford to just heat my room to t-shirt levels and put rugs everywhere, but I'm trying to figure out clothing that would work well without it while using a computer for hours. I'm not raynauds level of issues, but it makes sense this is mostly an computer worker issue too.
That is what most people I know do for a living, and often during personal time, including me - it's probably the most common job activity among HN readers. And what are we doing now to post these comments? And yet, I've never heard those complaints.
Also, I think you have things reversed: Active people are the ones who like to buy clothes with pit zips.
> your temperature will rise up a lot, so you may sweat a lot and then get cold fast again in your wet clothing
Tangentially: You can avoid this problem with the proper materials: Don't wear cotton in these situations - it is worse than nothing if damp; it chills you. Wear breathable materials that insulate when wet and dry quickly. Wool is probably best, and then 'fleece', which is effectively synthetic wool. Down (e.g., from geese) is even better but if it gets wet, it clumps up into useless balls; however, I've never seen it do that from perspiration, only from external water sources (rain, falling in a river, etc.). Synthetic down can be very warm and still insulates when wet; I suspect it's warmer per liter or per gram than wool, but I'm not sure.
Also, wear a wind-proof outer shell. Preventing the convection of wind does as much as anything to keep you warm.
> Managing good comfort while minimizing room-heating is not easy at all
In fact, it's very easy and people have been doing it for most of history: Put on a sweater. Are we really debating how hard that is? I mean, we can make anything hard, but ... wow.
