Each area of the body dissipates heat at different rates in order to keep a constant temperature. This is because the enzymes in your body (that catalyse with other substances to create everything your body needs to go on) are very sensitive to temperature (which is the quantum movements of atoms). Your head and body may not be the same temperature externally but that is because they are regulating your internal body temperature to keep a core constant.
I think this is to do with circulation to your hands and feet as you move them a lot. This extra blood causes the warmth.
cold
Heat flows from hot to cold because when hot and cold bodies contact with each other (thermal contact), the fast moving molecules of the hot body collide with slow moving molecules of the cold body; therefore the molecules of hot body become slower and body becomes cool, and the molecules of other body (cold) becomes faster and the cold body becomes hot. Notice: when molecules of a body moves faster it's kinetic energy increase therefore temperature increases and it becomes hot.

no. Cold is just the heat in your body leaving so people just think they are cold. Hot is just heat coming in your body.
Sensory receptors gives the sensation of hot or cold to a body. For example, heat receptors detect warmth while cold receptors detect the cold.
How hot or cold a persons body is.
its abnormal when body fells cold in hot temperature or cold in hot temperature because our body and mind adjusts themselves with according to surroundings. A normal and healthy persons body temperature is 37.5 degree celcius.
Undoubtfully no. Whenever a hot substance comes in contact with a cold one then heat energy always flow from the hot body to the cold body till equilibrium temperature is attained.
They both explode.
Each person's body tempature changes and is diffrent and the diffrent climate has alot to do with getting hot and cold.
The heat comes from fever which is the body's way to combat what is causing the cold.
