One time I was at work and I was on the phone with this guy and he was yelling at me about something and just being really really mean..and my bg dropped.. I think he just stressed me out big time..cuz I started getting weak and sweaty...It sucked...
I once watched my youngest have two front teeth extracted under a local.
It was absolutely horrible. My BG crashed so hard it was ridiculous. I had to ask the dentist for a juice pouch :)
A middle chapter in a book I'm reading mentions the development of speech in humans. It mentions a couple things that brought me back to this question:
When a person is at rest, about 20% of their energy is used by their brain.
Talking is "an energy expensive process" it involves a lot of organs, including specialized regions of the brain, and respiratory system, which we don't normally consider. This is why we are the only animals able to make the sounds that allows us to talk.
I would say that talking can absolutely drop your BG, but it is something that we normally wouldn't consider. Thanks for bringing it up.
