In this note, we revisit the thermal fluctuations generated during bouncing cosmology, taking Unruh effect into account. We find that due to the additional effect on temperature, the dependence of power spectrum on k will get corrected with an indication of blue tilt at large k region, which is in consistent with the case of vacuum initial conditions.
