we tell patients to avoid hot tubs druing pregnancy because the higher the temperature the higher the risk to the unborn fetus. there is some concern for temperatures above 104 degrees because it can affect brain development. if you think about a child or even you when you have a fever that high it can cause you to be delerious. i would take a bath that is at your body temperature or slightly higher.
