Nucleons in a hot pion gas are studied within the framework of chiral
soliton models which contain pions and also baryons as solitons of the
same chiral action. The semiclassical treatment of the soliton soluti
ons must be augmented by pionic fluctuations which requires renormaliz
ation to one loop, and finite temperatures do not introduce new ultrav
iolet divergencies and may easily be considered. Alternatively, a reno
rmalization scheme based on the renormalization group equation at fini
te temperature comprises and extends the rigorous results of chiral pe
rturbation theory and renders the low-energy constants temperature dep
endent, which allows the construction of temperature-dependent soliton
s below the critical temperature. The temperature dependence of the ba
ryon energy and the pion-nucleon coupling is studied. There is no simp
le scaling law for the temperature dependence of these quantities.
