Don't know for sure, but if you're pregnant or planning to be pregnant..don't use one continually.
I used to use them a lot....did start using the microwave grain bag and feel better about falling asleep with it than with a heating pad.
Mind you..there are ones with an timer on them....remember, you can burn yourself with them...been there done that.

I agree, the microwaveable ones with grains are nice and you don't have to worry.
Plus they smell good (I have a lavender one).
