We derive the finite-temperature quantum-tunneling rate from first principles. We generalize previous results for general initial states and identify distinct behavior in the high- and low-temperature limits, incorporating effects from background fields. We construct a consistent perturbative scheme that incorporates large finite-temperature effects.
