Popis:	We review recent work on thermal resonances and their connection with chiral symmetry and $U(1)_A$ restoration within the QCD phase diagram. In particular, the $f_0(500)$ and $K_0^* (700)$ states generated from $\pi\pi$ and $\pi K$ scattering within Unitarized Chiral Perturbation Theory (ChPT) at finite temperature allow one to describe scalar susceptibilities, which combined with Ward Identities yield interesting conclusions regarding the interplay between chiral and $U(1)_A$ restoration, key to understand the nature of the transition Comment: 6 pages, 2 figures, contribution to the proceedings of the 19th International Conference on Hadron Spectroscopy and Structure (HADRON 2021). Accepted for publication in Suplemento de la Revista Mexicana de F\'isica
