They only worry about your internal body temperature raising. So as long as you're not overheating yourself, you should be fine. My doctor okayed me to stay in the hot tub for as long as I want as long as it's set at 95 degrees.
I wouldn't make it super hot and don't stay in for a long time
I'm 36 weeks and take a hot bath at least 3 times a week.
thank yall for the input.
