I've heard it's because baby can't regulate their own temperature yet...so if you heat them up too much they can't cool down. But I'm not sure, so maybe research it?
I was told you can take hot baths and showers just not hot tubs . Reason being a hot tub is at a steady temperature as a shower and bath can and will get cooler as time goes on especially a bath .so it will not over heat your body or rise you heart rate . However don't make your bath super hot to begin with .
Cause I take hot baths every day I just make sure they aren't too hot and I drink ice water to keep baby cool
Thanks girls 😊😊
