Wats it mean wen u get a warmth feeling on part of your body?

VasodilationOrAware: All perceptions are in our brain's image/model of our body. Look up homunculus. In the body, there are just millions of nerve signal commands/minute, top-down + feedback back-up. If you relax arterioles to an area, blood flow & temp increases (from >flow of warmer blood from deeper in body). However, we can also just perceive greater warmth without this for other reasons, rarely well understood.
