But you know what heats a cold heart faster than blood from another body part?
Direct exposure to microwave radiation…
That’s what I mean, there’s a safe temperature differential to warm the body, and even stuff as conventional as a warm bath or hut tub can be too much.
If we shoot microwaves at a heart, the heat increase is waaaaaaaay above the safe limits.
So if someone was in a situation where the only method was microwave radiation, it wouldn’t result in an increase in heating without running serious risks.
There’s just no benefit and it introduces insane risks if you tried to do it slow enough.
