When wearing jacket+short on cold winter or going shirtless+full pant on hot sunny days or tucked in partially in blanket when sleeping, how does body control temperature uniformly?

Your body temperature isn’t uniform at all, that’s why in the past a thermometer without a logic board needed to be inserted into the rectum, or under the tongue, to get the *core temp*. It’s that core temp that needs to be maintained in a specific range, and the rest of your body varies wildly. Beyond that, blood flow and dilation/constriction of blood vessels which determines blood flow, are the main mechanisms to modify body temp, along with sweating.

We’re water cooled. Your blood flows to your hands, feet, and ears more easily when it’s hot, and cools you down through sweating. Then, when it’s cold, it doesn’t flow as easily to those far away parts of the body. That keeps the heat in, to the appropriate level.

This blood goes everywhere, so the whole body remains mostly the same temp.
