As well as the heat, I would consider just making sure there is fresh water to drink and soak in. The heat is key though. Monitor her response to the heat and to hydration. You may want to place her in a small locking tub to soak. Don't offer too many meals frequently bc that will reinforce refusals. The level of water to soak in shouldn't be deep at all just enough to cover her ventral scales and cloaca.
