I promise this story about microwaves is interesting.

Despite everything else he accomplished in his quite storied professional career as one of the last independent scientists... Including his work on the Viking mars landers! [LINK] To me he will always be the man who invented his own microwave to thaw frozen hamsters. The whole story is worth a watch since Tom Scott does an admirable job of explaining how he went digging up a weird fact expecting to debunk it only to wind up recording an amazing interview with James Lovelock [VIDEO] but if you’re impatient the interview with lovelock about cryopreserved hamsters and his "microwave" starts here [VIDEO]

They already studied this. It sometimes worked with small animals like mice, but fails as organisms get larger. There was a really interesting video about how microwaves were first used to test this: [VIDEO]

That's purely a size thing iirc. Lot quicker to get enough heat into a mouse to thaw it, than a human. Edit to add an interesting related video: [VIDEO]

This Tom Scott's video from last year about microwave ovens features a nice interview with Lovelock: [VIDEO]

Tom Scott interviewed him last year in a really wonderful video about microwaves. [VIDEO] > I found an article that said "The microwave was invented to heat hamsters humanely in 1950s experiments." And I thought, no it wasn't. ...was it? At over 100 years old, the man was remarkably coherent and healthy. Quite sad to hear he's passed now.

This where I can post Tom Scott’s video on Microwaves, in which James Lovelock is interviewed: [VIDEO] Spoiler warning, well you wouldn’t watch it if I didn’t tell you would you.

Yes, Tom Scott is one talented YouTuber. See, for example, his video on microwaving frozen hamsters back to life[0], in which he interviews the 101-year-old J. E. Lovelock, the scientist who did the work back in the fifties. [0] [VIDEO]

Tom Scott made a great video about it, he even got to the guy who started using microwaves for thawing entire small animals. Before microwaves (diathermic heating) they would use a hot piece of metal, like a large spoon. [VIDEO] And yes, you can unfreeze a rock solid rat, then see it walk around. This is why cryogenics was hyped so much, because it sort of works on small animals.
