while that is true I'm not convinced thats all this can be blamed on.... we use AC down here year round, it isnt like our home is 80-90s+ all the time.. our house inside ambient temp (away from ball rack/windows/ac vent/beardie cage/ exc im talking middle of the room temp) is about 70-73 during the day... sometimes slightly higher if were gone and turn the AC up to conserve energy. Although I hate to do it I would assume people in TN are keeping their homes warmer than we are down here where the outside temp is much hotter. but thats just my 0.02, take it for what its worth...
I personally wouldnt be so quick to make assumptions that someone is "retarded" or less capable to caring for their animals based on part of their husbandry alone.. perhaps she did have perfect husbandry and the animal wasnt healthy... or perhaps she fed it only mealworms and no salad/crickets.. go a step further and perhaps the animal wasnt all that healthy to begin with considering the PP said it was a baby bearded... a 55gal tank is WAY to big to begin with for a baby.. that has little to do with adequate heat IMO.
