We use the method of thermal QCD sum rules to investigate the effects of temperature on the neutron electric dipole moment d_n induced by the vacuum θ̅-angle. Then, we analyze and discuss the thermal behaviour of the ratio d_n θ̅ in connection with the restoration of the strong CP symmetry breaking.
