In this seminar I explore how a hot medium reshapes hadronic properties and the stability of two-hadron bound states. Working in imaginary time, one can compute one-loop self-energies through Matsubara-frequency summation and extract the resulting temperature-dependent propagators. Using these propagators in a schematic contact-interaction model, one can trace the poles corresponding to hadronic molecules as the temperature increases. The analysis reveals progressive broadening, mass shifts, and eventual dissolution of the molecular states near the critical region (T=150 MeV), providing quantitative criteria for their survival in heavy-ion collisions. This behavior may also be used to disentangle the compact and molecular components in the wavefunction of these states.
