I didn’t see the “hair dryer” thing. But I’m serious about some kind of electronic device to keep her energized. And before she starts throwing ashtrays at employees someone simply “turns her off”.
Go back and look if you have it recorded. It looked like whoever was doing it thought they were out of the frame, but they weren’t even close. It was extremely visible and I couldn’t believe what I was seeing. They were clearly trying to cool her down right at the moment when she was really looking sickly.
