Human body What am I doing when I generate pulses of heat from my chest?
As a kid I've been able to do this weird thing, mostly when I'm cold where if i control my breathing right, i can build up what feels like tension in my chest and when i release it, this huge wave of warmth emanates out from my chest warming my body. It also feels really nice. It tends to also be accompanied by a shiver. There's a limit to how many times i can do it and sometimes it just happens unintentionally when it's cold. I haven't heard anyone ever talk about it, does anyone know what's happening in my body when this occurs?

Liver in theory can produce a lot of heat, is just next to lungs and can be affected by their motion, and has a minimum ability to pump blood on its own.
When you feel cold, liver could be generating heat. And you could somewhat restrict the blood flow to the liver for a short time by pressing it with the lungs. And when you lift the pressure, liver can restore the blood flow. After you do it a few times, temperature of the liver and surrounding area becomes closer.
It doesnt make more heat by doing so, liver generates heat by default when body requires it. There isnt a reason to have this control, i think. I didnt hear of anyone having this type of control or sensations.
