Actually, hot tubs ARE SAFE. Honest, I swear. There was a very good study quoted in Midwifery Today earlier this year that said that in a 104* tub, it took something like 2-4 HOURS for a woman's body temp to raise even half a degree. And all the women WANTED to get out before then. Raised temps aren't even remotely dangerous until AT LEAST over 100. Hot tubs are safe! (Well, maybe not with the chlorine, but that's a different topic.

)
We're mammals - it
really takes a
lot to raise our core temp significantly. Yes, if it's 110 degrees where you are and you're dehydrated, I might worry, but more because of the risk of passing out than of damaging the baby.
And I don't think you're insane at all, Jenny, and if it makes you feel better to avoid hot tubs and saunas, by all means do so. It's just not evidence based (like much of OB recommendations - it was a good theory, but isn't supported by science).
