  In this paper we apply hydrodynamics for systems with continuous broken
symmetries to heavy ion collisions in the framework of (1+1) dimensional
Bjorken model. The temperature profile with respect to proper time determined
in that context exhibits no differences with the ideal fluid. On the contrary,
it is shown that the profile obtained when M\"{u}ller-Israel-Stewart second
order theory of dissipation is included on top of standard hydrodynamics
indicates a slower cooling of the system.
