Gauss + collective minimal understanding on electromagnetic fields over time(by Scientific studies), would be enough to make me move the bed...
Immediately!
Even if you research and consider after that, it is a minimal risk, it has horrid possible outcomes if true, add moving the bed is an easy minimum effort and move the bed.
I would see it similar to sleeping on the edge of a cliff 500ft above the ground. Even if you don't roll around when you sleep, I would tell you "It's a 20ft wide cliff! Sleep away from the edge!!"

If it is really deeply worrying you, that will likely be physically detrimental to you as well in the long run.
So move the bed and sleep in peace.
