Using the QCD sum rules, we investigate the effects of temperature on the nucleon below the phase transition. The mass and width of the nucleon are analyzed using various parametrizations of the nucleon continuum. Overall, the nucleon mass is found to depend substantially on temperature variations in the quark condensate, irrespective of the continuum parametrization. Our results are compared with the ones discussed in the context of the chiral approach.
