Andy is not a cold doll !

Her body is warm as every human body, with some parts with different heat as human.

see the above pic :

You won't have a ice-block in your arms but a welcome and warm doll.

The blue zones are less warm than the red ones. 
The body's temperature in the blue zones is between : 
70 à 75 °F ; 
and in red and pink zones between :
78.8 à 89.6 °F.

in bed Andy's body warm can go up to 100°F, as every human temperature.

The heat is obtained by hot wires in the internal silicone couch that make the skin. The electricity comes from an external electric power supply low tension.
