In this work we review converging evidence, from several lines of research, which suggeststhat altruism in humans can be intrinsically rewarding. Various investigations illustrate how humanaltruism can have beneficial effects on health and well being. In this contribution we propose a modelthat includes positive effects of altruism. These beneficial effects lead to significant changes in thedynamics of the system, favouring higher levels of altruism and facilitating abrupt changes towardscooperation. In the present model, social modulation occurs at both individual and collective levels.The potential beneficial role of altruism proposed here may account for its occurrence among non-kinand beyond reciprocity.
