Why covering our shoulders with a mantle or blanket is so efficient at warming us?
Why isn't that common to cover with a blanket other parts of our body when we feel cold, like the belly or lower back?
My mom always says warm you neck. Her explanation is that an artery runs through it and you can lose heat quite quickly there.
She was a nurse, so I do trust her.
Correct answer here.
also the nasal passages since theres a ton of blood vessels. thats why it gets cold, because the nose is the first to restrict blood vessels in the head.

It... is?
First of all, I'm talking about when I'm outside, not in bed. I start covering my belly if there is strong wind, otherwise I start by covering my shoulders before covering the rest of the body, if the blanket is big enough
You lose a lot of your hear through your head. "If your feet are cold, put on a hat" - camping advice
Wasn't that a stupid study where they didn't cover the heads and then concluded that people lost most of their heat through the head?
Cannot remember if the study was stupid or if peoples interpretations of it where. But when covered up else where you will lose a lot of heat through your head. More so then if just an arm or just a leg was exposed as with your arms and legs your body will slow down blood flow through them to try and converse your core temperature - it cannot do that with your head.
I have heard that you lose the most heat through your head from multiple sources as well. That would make sense, because I'm pretty sure the brain uses the most energy among all organs.
Edit: Probably depends on how you measure it. Per cm²? Total area? The latter makes it more likely that you lose most heat through your torso.
Bin mir aber nicht sicher und lasse mich gerne eines besseren belehren.
Afaik there is a specific spot between the shoulders with brown fat that acts as a temperature regulator. As a caveat, i read this in a (scientific) article decades ago.
More or less. It varies a bit, but it extends a tiny bit along the shoulders and down the spine.
The brown fat is basically a metabolic heater, so insulating it will help warm things up.
I always wet the back of my neck before entering a cold body of water to make it easier. Does it work or is it psychological? I'm not sure.
Most likely works, since evaporation helps keep your temps down
My dad always said that you need to cover your feet to warm up the fastest, so I dunno :3.. that's the one I always did
Heat rises. It gets trapped under the blanket and helps keep you warm.
Semi related, your body loses the most heat through your head so wearing a warm hat on a cold day makes a huge difference.
For me, it has always been my triceps. If they are warm, the rest of my body is warm.
After reading through the comments, I'm imagining everyone walking around with a constant stream of steam puffing up from their head. What if the heat we lose was visible at all times?
Have you tried sweating in extreme cold? You'll see steam/condensation raising from your head
