  Motivated by the very recent discovery of the strange hidden-charm exotic
state $Z_{cs}(3985)$ by the BESIII Collaboration, we study possible
interpretation of this exotic state both at $ T= 0 $ and $ T\neq 0 $. We
analytically compute the mass and meson-current coupling constant of this
resonance with spin-parity $ J^{PC} = 1^{+-}$ at finite temperature
approximation up to sixth order of the thermal operator dimension including
non-perturbative contributions. Extracting thermal mass and meson-current
coupling constant sum rules, the modifications on properties of $Z_{cs}(3985)$
state in hot medium is determined. As a by product, the hadronic parameters of
the bottom partner of $Z_{cs}(3985)$ is estimated as well. Moreover the search
of temperature effects on the hadronic parameters of hidden-charm meson
$Z_{cs}(3985)$ and the bottom partner make us understand the phase transitions,
chiral symmetry breaking and the properties of hot-dense matter in QCD.
