The primary reason you can safely hold your fingers on both sides of a candle flame without getting burned is due to convection. Convection involves the movement of heat through a fluid (which includes gases like air) in a manner that the hotter, less dense fluid rises and the cooler, denser fluid sinks. This process circulates heat away from the flame and your fingers, preventing direct heat transfer that could cause burns.
