Abstract: In this contribution we propose that the possible existence of a component of self-annihilating dark matter in the universe may result in a local inner core warming of medium-age neutron stars on a time-scale of $\sim 10^2$ yr. The energy released from annihilation of a massive ($m_{\chi}\gtrsim$ TeV) dark matter particle in the central regions of the star could be capable of injecting an extra neutrino/photon component allowing a positive emissivity, opposed to the usual negative values for the standard cooling processes. As a result, an enhanced early warming era in the neutron star coolig scenario may result.
