For one thing, they really seem to have worried about accidentally being buried alive:

It is unclear to me how prevalent those fears were. The device was invented sure, someone had this fear or someone thought someone did, but how common was that really.

They were desperately concerned about women’s uteruses falling out and wanted them to avoid strenuous activities like reading fiction.

I'm curious as well.
