Temperature swings can definitely cause restless behavior, I noticed that especially in my Ratsnakes.

One year our AC gave out. In the deep south, fourth of july weekend ...

It got HOT in the house. I got a couple portable AC's and ran fans all over the house, kept the blinds drawn. It was quite comfy for the Ball Pythons, but the Russians started cruising like mad. They didn't have any heat source at all, even with the AC on, because they prefer "mild" temps.

They were definitely un-comfortable with the ambient heat up in the 80's. If it had gotten any hotter in the house I would have had to go to a hotel. Thankfully we were able to "just" keep it tolerable.
