No, it's not.

The sensation of warmth/heat you're experiencing is the result of the transfer of heat from your palms to the molecules in the space between them.

The tingling or pressure sensations could be the result of a number of things. It could be the result of holding your hands in the same position for a prolonged period of time, poor blood circulation, your imagination, wishful thinking, etcetera.
